Can You Legally Cut Your Children Out of Your Will in the UK?

In England and Wales, you have what’s known as testamentary freedom — the right to leave your assets to whoever you choose in your will. Unlike many European countries that operate under civil law systems with forced heirship rules, there is no automatic right for children to inherit. However, certain legal protections exist for children who may be excluded from a will, and understanding them is essential before making any decisions about your estate.

We’ll explore the legal framework surrounding wills and inheritance in England and Wales, including the rules governing disinheritance and the claims that excluded family members can bring. This knowledge will help you make informed decisions and — critically — plan your estate in a way that reduces the risk of your wishes being overturned after your death.

Key Takeaways

• England and Wales grant broad testamentary freedom, but the Inheritance (Provision for Family and Dependants) Act 1975 allows excluded dependants to challenge a will.
• Simply omitting a child from your will is not enough — you should explicitly acknowledge and address the exclusion, with documented reasoning kept separately.
• Disinheriting a child can have significant legal and emotional consequences, including costly court disputes that erode the estate for everyone.
• Alternatives such as discretionary trusts, specific bequests, and lifetime gifts can achieve your goals while reducing the risk of a successful claim.
• Specialist legal advice is essential to ensure your will is robust and your reasons for disinheritance are properly documented.

Understanding Inheritance Laws in the UK

Navigating inheritance law in England and Wales is crucial for ensuring your wishes are respected after you’re gone. The law attempts to balance your freedom to dispose of your assets as you choose with protections for family members who may have been financially dependent on you. Getting this balance right — through proper planning — is the difference between a legacy that holds firm and one that ends up in court.

The Importance of a Will

Having a valid will is the foundation of any estate plan. Without one, your estate is distributed under the rules of intestacy — a rigid statutory formula that may not reflect your wishes at all. For example, under intestacy, a cohabiting partner of 30 years could receive nothing, while estranged children could inherit everything. It’s one of the most common — and most easily avoided — estate planning failures.

A well-drafted will doesn’t just state who gets what — it builds a defensible record of your intentions. This is especially important if you’re considering excluding a child, because courts will scrutinise your will closely if a claim is brought under the Inheritance (Provision for Family and Dependants) Act 1975. The clearer and more carefully constructed your will, the harder it becomes for anyone to overturn it.

Legal Framework Surrounding Wills

The law governing wills in England and Wales is primarily set out in the Wills Act 1837, which establishes the formal requirements for a valid will. Beyond validity, the law provides mechanisms for certain people to challenge a will if they believe they’ve been left without reasonable provision.

The most important piece of legislation in this area is the Inheritance (Provision for Family and Dependants) Act 1975, which gives eligible individuals — including children of any age — the right to apply to the court for reasonable financial provision from the estate. Understanding how this Act works, and how to plan around it, is essential for anyone considering disinheritance.

Inheritance (Provision for Family and Dependants) Act 1975

The Inheritance (Provision for Family and Dependants) Act 1975 is the single most important piece of legislation affecting disinheritance in England and Wales. It provides a safety net for family members and dependants who have not received reasonable financial provision — whether through the will or under the intestacy rules.

A key distinction under the Act is how “reasonable provision” is measured. For a surviving spouse or civil partner, the court considers what would be reasonable in all the circumstances — not limited to mere maintenance. For all other applicants, including adult children, the standard is limited to what is reasonable for their maintenance — a significantly lower threshold.

This means that while an adult child can bring a claim, they face a higher burden of proof than a surviving spouse. They typically need to demonstrate a genuine financial need or dependency, not simply that they expected to inherit. The landmark case of Ilott v The Blue Cross [2017] confirmed that courts will not routinely override a testator’s wishes simply because a child has been excluded — the Supreme Court awarded just £50,000 from an estate of approximately £486,000, emphasising that the maintenance standard is a real constraint.

This legislation underscores why proper planning and documentation are so important. A will that simply ignores a child is far more vulnerable than one that explicitly acknowledges the child, explains the reasoning, and is supported by a separate signed confidential statement.

The Concept of Disinheritance

Disinheritance — the deliberate exclusion of a family member from your will — is a decision that carries both legal weight and emotional consequences. In England and Wales, testamentary freedom means you are legally permitted to disinherit anyone, including your children. But the right to do so and the wisdom of doing so are two different things entirely.

What Does It Mean to Disinherit?

To disinherit someone means to deliberately exclude them from receiving any share of your estate upon your death. When it involves children, it goes against a deeply held societal expectation — and that’s precisely why the 1975 Act exists as a potential backstop for those with a genuine financial need.

Disinheritance can range from a complete exclusion to leaving a significantly reduced share compared to other beneficiaries. Whatever form it takes, the legal approach matters enormously. Simply leaving someone out of your will without acknowledgement is far riskier than explicitly addressing the exclusion and documenting your reasons in a separate confidential statement. The difference between those two approaches can be the difference between a will that holds up in court and one that doesn’t.

Reasons for Disinheriting Children

Parents may choose to disinherit their children for a variety of reasons. Some common factors include:

• Long-term estrangement or a complete breakdown in the relationship
• The child is already financially independent or has received substantial lifetime gifts
• Serious disagreements over values, lifestyle choices, or behaviour — such as addiction or criminality
• A desire to provide for a more vulnerable family member, such as a disabled child or an elderly partner
• A wish to leave assets to charitable causes
• Concerns about the child’s ability to manage money, or a risk that inherited assets could be lost to creditors, divorce, or poor financial decisions

Each of these reasons carries different weight in the eyes of the court if a claim is later brought. For example, a court is far more likely to uphold disinheritance of a financially independent adult child than the exclusion of a young child who was financially dependent on the deceased. The better your reasons are documented, the stronger your position.

Emotional Implications of Disinheritance

The decision to disinherit a child can have profound emotional consequences — not just for the excluded child, but for the wider family. Feelings of rejection, guilt, anger, and betrayal are common, and the situation can fracture relationships between siblings and other relatives who may disagree with the decision.

It’s crucial to consider the potential for lasting family conflict. Even where a will is legally unassailable, the emotional damage of disinheritance can persist for generations. This is one reason why many estate planning specialists — including Mike Pugh at MP Estate Planning — often recommend exploring alternatives that achieve similar goals without the nuclear option of complete exclusion. A discretionary trust, for example, can give you the control you need without cutting someone out entirely.

By understanding disinheritance, the motivations behind it, and its emotional fallout, you can make a more informed decision about whether it’s truly the right approach — or whether a more nuanced strategy might better serve your family’s long-term interests. As Mike often says: “Plan, don’t panic.”

Legal Requirements for Disinheriting Children

To disinherit a child legally, your will must meet the formal requirements set out under the law of England and Wales. A will that fails to comply with these requirements can be declared invalid — meaning your estate would be distributed under the intestacy rules, potentially giving the very child you wished to exclude a statutory share.

Formal Will Requirements

Under the Wills Act 1837, for a will to be valid in England and Wales, it must satisfy these requirements:

• The will must be in writing (handwritten or typed — both are acceptable).
• The testator (the person making the will) must sign or acknowledge the will in the presence of two witnesses who are both present at the same time.
• Both witnesses must then sign the will in the presence of the testator.
• The testator must have mental capacity to make the will (known as “testamentary capacity”) and must not be acting under undue influence or duress.

These requirements may seem straightforward, but failing to meet even one of them — for example, having only one witness present at the time of signing — can render the entire will invalid. When disinheritance is involved, this is an especially costly mistake.

Necessary Language in Wills

When drafting a will that disinherits a child, the language used is critical. Simply omitting a child’s name is not sufficient — and is one of the most common mistakes people make. A court could interpret the omission as an oversight rather than a deliberate decision, which significantly weakens the will’s defensibility if a 1975 Act claim is brought.

Instead, the will should explicitly name the child and state that the testator has intentionally decided not to make provision for them. Many solicitors also recommend preparing a separate signed statement — sometimes called a “letter of wishes” or a “statement of reasons” — explaining the rationale behind the exclusion. While not legally binding, this document provides powerful evidence of the testator’s intentions if the will is later challenged. Crucially, this statement should be kept separate from the will itself, because once a Grant of Probate is issued, the will becomes a public document — anyone can obtain a copy from the Probate Registry for a small fee.

Witnesses and Signatures

The witnessing and signing process is a fundamental safeguard against fraud, forgery, and undue influence. Both witnesses must be present at the same time when the testator signs (or acknowledges their signature), and each witness must then sign the will themselves.

Crucially, witnesses — and their spouses or civil partners — must not be beneficiaries under the will. If a witness is also named as a beneficiary, their gift under the will is void, though the will itself remains valid. It’s also wise to choose witnesses who are likely to be available to give evidence if the will is ever contested — younger, healthy individuals who know the testator well are ideal choices.

Where disinheritance is involved, some solicitors recommend obtaining a medical assessment of the testator’s mental capacity at the time the will is signed. This is especially prudent for older testators or those with any health conditions that could later be used to challenge the will. A contemporaneous medical report confirming testamentary capacity can be decisive in defeating claims of lack of capacity or undue influence.

The Role of Family Provision Claims

The Inheritance (Provision for Family and Dependants) Act 1975 is the primary mechanism by which a disinherited family member can challenge a will in England and Wales. Understanding how these claims work — and how to defend against them — is essential for anyone considering excluding a child from their estate.

What is a Family Provision Claim?

A family provision claim is a court application made under the 1975 Act by someone who believes the deceased’s will (or the intestacy rules) did not make reasonable financial provision for them. The claim must be brought within six months of the Grant of Probate or Letters of Administration being issued, although the court has discretion to extend this deadline in exceptional circumstances.

It’s important to understand that a successful claim doesn’t necessarily mean the court will rewrite the entire will. The court can make a range of orders — from a lump sum payment to periodic payments or the transfer of specific property — tailored to what it considers reasonable in the circumstances. During the claim process, the estate’s assets (including property) can remain frozen, which delays distribution to the beneficiaries you did intend to provide for.

Who Can Make a Claim?

The Act sets out specific categories of people who are eligible to bring a claim:

• The spouse or civil partner of the deceased
• A former spouse or civil partner who has not remarried or entered into a new civil partnership
• A child of the deceased (of any age — adult children can and do bring claims)
• Any person treated by the deceased as a child of the family in relation to a marriage or civil partnership (e.g., stepchildren)
• Any other person who was being maintained, wholly or partly, by the deceased immediately before their death

For a claim by an adult child to succeed, they generally need to demonstrate a genuine financial need or dependency — not simply a moral expectation of inheritance. The court applies the maintenance standard, which is a significantly lower bar than what a surviving spouse can claim. For more detailed information, you can visit Higgs LLP’s article on excluding a child from a will.

How Claims Are Assessed

When assessing a family provision claim, the court considers a wide range of factors, including:

The court’s primary objective is to determine what constitutes “reasonable financial provision” — for adult children, this means provision for their maintenance, not a windfall inheritance. This is a lower bar than many people expect, but it is still a bar that must be cleared. The stronger your documentation and the more professionally your will has been drafted, the harder it is for a claimant to clear that bar.

Alternatives to Disinheritance

Complete disinheritance is not the only option. For those looking to control how assets are distributed — or to protect assets from a particular child’s creditors, divorce, or poor financial decisions — there are alternatives to disinheritance that can achieve the same goals with less legal risk and family conflict.

Setting Up Trusts

A discretionary trust is one of the most powerful alternatives to outright disinheritance. Rather than giving a child an absolute inheritance (which they could squander, lose in a divorce, or have seized by creditors), you place assets into a trust managed by trustees. The trustees then have absolute discretion over when, how, and whether to distribute anything to each beneficiary. No beneficiary has a legal right to the trust assets — and that is the key protection mechanism.

This approach has several key advantages:

• Control over distribution: Trustees can withhold funds from a beneficiary who is in financial difficulty, going through a divorce, or struggling with addiction — then release assets when circumstances improve. This is far more flexible than an outright gift in a will.
• Asset protection: Because no beneficiary has a legal right to the trust assets (in a discretionary trust), those assets are protected from creditors, divorce settlements, and local authority care fee assessments. As Mike Pugh puts it, the answer to “what assets do you own?” becomes: “What house? I don’t own a house.”
• Reduced claim risk: Including a child as a potential beneficiary of a discretionary trust — even if you intend for trustees to exercise their discretion against distributing to them — can significantly weaken any 1975 Act claim, because the child has technically been “provided for” within the trust structure.
• Inheritance tax planning: Depending on the trust structure, there may be IHT planning benefits. For example, a Family Home Protection Trust can protect the family home while retaining the Residence Nil Rate Band (worth up to £175,000 per person, or £350,000 for a married couple).

Discretionary trusts can last up to 125 years in England and Wales and are the most commonly used trust type — accounting for the vast majority of family trusts. England invented trust law over 800 years ago, and the discretionary trust remains its most effective innovation for protecting family wealth. As Mike Pugh of MP Estate Planning often says: “Trusts are not just for the rich — they’re for the smart.”

Making Specific Bequests

Another approach is making specific bequests within your will. Rather than excluding a child entirely, you leave them a defined gift — perhaps a sentimental item or a modest sum — while directing the bulk of your estate elsewhere. This approach acknowledges the child without giving them an equal share.

Even a modest pecuniary legacy can make a significant difference to the defensibility of your will. A child who has received something has a much weaker basis for claiming they were not “reasonably provided for” than one who received nothing at all. Combined with documented reasoning, this approach can be highly effective.

Gifts During Your Lifetime

Making gifts during your lifetime is another strategy worth considering. By transferring assets to your children or other beneficiaries while you’re still alive, you can see the benefit your gifts bring — and you may also reduce the size of your estate for inheritance tax purposes.

Key points to understand about lifetime gifts:

• Gifts to individuals are treated as Potentially Exempt Transfers (PETs) — if you survive seven years, the gift falls completely outside your estate for IHT purposes.
• You have an annual exemption of £3,000 per tax year (with one year’s carry-forward), plus a small gifts exemption of £250 per recipient per tax year. There are also wedding gift exemptions: £5,000 from a parent, £2,500 from a grandparent, or £1,000 from anyone else.
• Regular gifts from surplus income — provided they form a pattern and don’t affect your standard of living — can be exempt from IHT immediately under the normal expenditure out of income exemption. This must be properly documented to satisfy HMRC.
• However, if you give away an asset but continue to benefit from it (for example, gifting your home but continuing to live in it rent-free), the gift will be treated as still in your estate under the Gift with Reservation of Benefit (GROB) rules — even if you survive the seven years. This is one of the most common traps in estate planning, and it’s why specialist advice matters.

By exploring these alternatives to disinheritance, you can create a more robust estate plan that reflects your wishes, reduces the risk of a successful legal challenge, and — where possible — minimises unnecessary family conflict. Plan, don’t panic.

Potential Consequences of Disinheritance

Disinheritance is not just a legal decision — it can ripple through your family for years, and potentially end up in court. Before making the decision, it’s worth understanding exactly what you’re risking.

Family Friction and Legal Disputes

One of the most immediate consequences of disinheritance is the potential for bitter family conflict. Disputes frequently arise between the disinherited child and siblings or other relatives who have been named in the will. These disputes can escalate into formal legal proceedings under the Inheritance (Provision for Family and Dependants) Act 1975.

Defending a 1975 Act claim is expensive. Legal costs are typically borne by the estate (at least initially), which means that even if the claim fails, your intended beneficiaries may receive significantly less than you planned. Contested estates can take years to resolve, during which time assets — including property — remain frozen and cannot be distributed. The whole estate is essentially held hostage by the dispute.

Impact on Family Relationships

The emotional impact of disinheritance often outlasts any legal dispute. Siblings may feel forced to “take sides,” and the resulting divisions can persist for decades — sometimes permanently. Grandchildren may grow up estranged from cousins, aunts, or uncles because of a dispute they had no part in creating.

It’s worth weighing these consequences carefully against the reasons for disinheritance. In many cases, a discretionary trust — where the child is named as a potential beneficiary but trustees have the power to withhold distributions — can achieve the same practical result without the scorched-earth consequences of outright exclusion. The child is technically “provided for,” which weakens any legal claim, while the trustees retain full control over whether anything is actually distributed.

Public Perception and Reputation

There’s also a practical consideration that many people overlook: once a Grant of Probate is issued, your will becomes a public document. Anyone can obtain a copy for a small fee from the Probate Registry. If your will contains blunt or unflattering statements about a child, those words will be permanently on the public record.

This is another reason why a separate, confidential letter of wishes or statement of reasons — rather than detailed reasoning within the will itself — is often the better approach for documenting your reasons. The letter is not a public document and can express your reasoning in a more measured way, while still providing strong evidence of your intentions if the will is ever challenged.

Understanding these broader implications — legal, emotional, and reputational — will help you make a more informed decision about how to structure your estate plan.

Ensuring Your Wishes Are Followed

A well-structured will is just the starting point. Ensuring your wishes are actually carried out requires ongoing attention, the right people in the right roles, and clear communication.

Communication with Family Members

One of the most effective ways to prevent disputes after your death is to have honest conversations with your family during your lifetime. We’re not suggesting you share every detail of your will — but giving your family a general understanding of your intentions can prevent the shock and sense of injustice that often triggers legal claims. For more thoughts on this, see our page on when to tell your children what’s in your will.

Where disinheritance or unequal distribution is involved, explaining your reasoning — even in broad terms — can make the difference between a family that grieves together and one that ends up in court. It’s a difficult conversation to have, but it’s far better to have it while you’re alive and can explain your thinking than to leave your family to discover it in a solicitor’s office after your death.

The Role of Executors

Your executors are the people responsible for administering your estate after your death — applying for the Grant of Probate, paying debts and inheritance tax, collecting assets, and distributing them to beneficiaries. Choosing the right executors is one of the most important decisions in your estate plan.

When selecting executors, consider:

• Their ability to handle financial and administrative tasks under pressure
• Their willingness to act impartially — particularly important if family dynamics are complicated or disinheritance is involved
• Whether they have the time and capacity to manage the process, which typically takes between 3 and 12 months (longer where property needs to be sold)
• Whether appointing a professional executor (such as a solicitor) might reduce the risk of disputes, especially in contentious estates

It’s essential to discuss the role with your chosen executors in advance. Being named as executor without prior knowledge can come as an unwelcome surprise, particularly in contentious estates where they may face immediate legal challenges.

Keeping Your Will Updated

Updating your will regularly is vital. Life events — marriages, divorces, births, deaths, changes in financial circumstances, changes in relationships — can all affect whether your will still reflects your true intentions.

A particularly important point: marriage automatically revokes an existing will in England and Wales (unless the will was made “in expectation of” that specific marriage). Divorce does not revoke a will, but it does treat the former spouse as if they had died for the purposes of executorship and any gifts made to them — which may have unintended knock-on effects on the rest of your estate distribution.

We recommend reviewing your will at least every three to five years, and immediately after any major life event. It’s also important to review your will in light of changing tax thresholds — the inheritance tax nil rate band has been frozen at £325,000 since 2009 and is set to remain frozen until at least April 2031, meaning more families than ever are being caught by IHT. By maintaining an up-to-date will and communicating openly with your family, you can have genuine peace of mind that your estate will be handled according to your wishes.

Professional Guidance and Legal Advice

If you’re considering disinheriting a child — or even making an unequal distribution — professional legal guidance isn’t just advisable, it’s essential. The law in this area is nuanced, and mistakes in drafting can undermine your entire estate plan. As Mike Pugh often says: “The law — like medicine — is broad. You wouldn’t want your GP doing surgery.”

When to Consult a Solicitor

You should consult a solicitor or specialist estate planner whenever your estate involves any complexity — and disinheritance certainly qualifies. An experienced professional can advise on how to structure your will to maximise its defensibility against a 1975 Act claim, whether a discretionary trust might be a better vehicle for your intentions, and how to document your reasoning effectively.

This is particularly important where the estate includes property (the average home in England is now worth around £290,000), where there are blended families involved, or where one child has significant financial needs while another does not. With the IHT nil rate band frozen at £325,000 and the Residence Nil Rate Band at £175,000 per person, the intersection of disinheritance planning and inheritance tax planning requires specialist knowledge.

Finding Experienced Will Writers

Not all will writers are equal. When looking for a professional, check whether they hold membership of a recognised professional body such as the Society of Trust and Estate Practitioners (STEP) or the Institute of Professional Willwriters (IPW). For trust-based planning, look for specialists who work specifically in this area — generalist high-street solicitors may not have the depth of expertise required for complex trust arrangements or contentious disinheritance situations.

MP Estate Planning, founded by Mike Pugh, specialises in trust-based estate planning and is the first and only company in the UK that actively publishes all prices on YouTube — so you know exactly what you’re paying before you pick up the phone.

Costs Involved in Creating a Will

A straightforward will from a solicitor typically costs a few hundred pounds. More complex wills involving trusts, disinheritance provisions, and detailed documentation of reasoning will cost more — but when you consider what’s at stake (the average UK house price is around £270,000-£290,000, and inheritance tax is charged at 40% on estates above the nil rate band of £325,000), the cost of proper planning is modest by comparison.

If your estate plan involves a trust, setup costs typically start from around £850 for a straightforward trust. When you compare that to the potential cost of care fees (currently averaging £1,200-£1,500 per week), the erosion of a contested estate through legal fees, or a 40% IHT charge on everything above the nil rate band, proper planning represents one of the most cost-effective forms of financial protection available. A trust costs roughly the equivalent of one to two weeks of residential care — a one-time fee versus an ongoing cost that can drain an estate to below the £23,250 self-funding threshold.

By investing in professional guidance, you’re not just creating a document — you’re building a defensible plan that protects your wishes and your family’s future. As Mike puts it: “Not losing the family money provides the greatest peace of mind above all else.”

Common Misconceptions About Disinheritance

Disinheritance is surrounded by myths and misunderstandings — many of them imported from American legal dramas that bear no resemblance to how the law works in England and Wales. Let’s set the record straight.

Myths Surrounding Wills and Inheritance

Several persistent myths cause unnecessary confusion:

• Myth: Children have an automatic right to inherit in the UK. Reality: There is no automatic right to inherit in England and Wales. Testamentary freedom means you can leave your estate to whoever you wish. However, children (and other dependants) can bring a claim under the 1975 Act if they believe reasonable provision has not been made for their maintenance. This is a claim right, not an inheritance right — there is a significant difference.
• Myth: If you disinherit a child, the court will simply overturn your will. Reality: The court does not lightly override a testator’s wishes. The Supreme Court in Ilott v The Blue Cross [2017] made clear that adult children must demonstrate a genuine financial need — mere disappointment at being excluded is not enough. The court awarded just £50,000 from an estate of approximately £486,000, demonstrating real restraint.
• Myth: A will is invalid if it disinherits a family member. Reality: A will’s validity depends on meeting the formal legal requirements (writing, signature, witnesses, capacity). Who you include or exclude has no bearing on validity — though it may affect whether the will is challenged.
• Myth: You can’t disinherit a child if you’re divorced. Reality: Your right to make (or not make) provision for a child is entirely separate from your marital status. However, if there are existing court orders from divorce proceedings regarding financial provision for children, those may still apply and take priority.
• Myth: Putting assets into a trust is only for the wealthy. Reality: With the average home in England now worth around £290,000 and the IHT nil rate band frozen at £325,000, ordinary homeowners are now firmly in the estate planning territory that used to be reserved for the wealthy. A discretionary trust can protect a family home from care fees, divorce, and inheritance tax — regardless of the family’s overall wealth.

Understanding Your Rights

It’s crucial to understand both your rights as a testator and the rights of potential claimants. In England and Wales, the balance tips strongly in favour of testamentary freedom — but not absolutely. The 1975 Act exists as a safety valve for genuinely vulnerable dependants.

To minimise the risk of a successful claim against your estate:

1. Make a clear, unambiguous will that explicitly names the excluded child and states the exclusion is deliberate.
2. Prepare a separate signed and dated confidential statement documenting your reasons — this is not included in the will itself (which becomes a public document after Grant of Probate) but is kept with your estate planning papers.
3. Consider whether a discretionary trust might achieve your goals with less risk — naming a child as a potential (but not guaranteed) beneficiary undermines their claim significantly.
4. Obtain a medical assessment of your testamentary capacity at the time of signing, particularly if you are elderly or have any health conditions that could be used to challenge the will.
5. Seek specialist legal advice — not just any solicitor, but one experienced in contentious probate and trust planning. The law, like medicine, is broad — you need a specialist.

Clarifying Legal Terminology

Understanding the correct terminology helps you navigate this area with confidence:

• Disinheritance: The deliberate exclusion of someone from your will. Legal in England and Wales, but subject to challenge under the 1975 Act.
• Testamentary freedom: The principle that you may distribute your estate as you wish in your will — a cornerstone of English law, not shared by most civil law jurisdictions in Europe.
• Family provision claim: A court application under the Inheritance (Provision for Family and Dependants) Act 1975 by someone who believes the will (or intestacy rules) did not make reasonable financial provision for them.
• Maintenance standard: The threshold applied to claims by adult children — the court can only award what is reasonable for the claimant’s maintenance, not an outright share of the estate.
• Testamentary capacity: The mental ability to understand the nature and effect of making a will, assessed at the time the will is executed.
• Discretionary trust: A trust arrangement where trustees have absolute discretion over distributions to beneficiaries. No beneficiary has a legal right to the trust assets, making it the most common and effective trust type for family wealth protection in England and Wales.
• Letter of wishes: A confidential, non-binding document from the settlor or testator to the trustees, setting out their wishes for how the trust assets should be managed and distributed. It provides guidance without creating legal obligations.

Understanding these terms — and the distinctions between them — is essential for anyone considering disinheritance as part of their estate plan.

Case Studies: Disinheritance in the UK

Real-world cases illustrate both the power and the limits of testamentary freedom in England and Wales. These cases provide invaluable guidance on what works, what doesn’t, and how courts approach family inheritance disputes.

Notable Legal Cases

The most significant case in this area is Ilott v The Blue Cross [2017] UKSC 17. Heather Ilott had been estranged from her mother, Melita Jackson, for 26 years. Mrs Jackson left her entire estate (around £486,000) to three animal charities. Heather brought a claim under the 1975 Act.

The case went all the way to the Supreme Court, which ultimately awarded Heather £50,000 — enough to allow her to buy her council house, but far less than the £143,000 the Court of Appeal had previously awarded. The Supreme Court emphasised that the maintenance standard applies to adult children and that a testator’s wishes — even contentious ones — deserve respect.

This case established several important principles: adult children do not have an automatic entitlement to a share of the estate; the court will consider the testator’s documented reasons for disinheritance; and the maintenance standard for adult children is a real limitation on what the court can award. The fact that Mrs Jackson had written a detailed letter explaining her reasons — even though the court ultimately made some provision for Heather — demonstrates the critical importance of documenting your reasoning.

For more information on the legal aspects of disinheritance, you can visit BLB Solicitors’ guide on whether a parent can disinherit a child.

Lessons Learned from Disinheritance Disputes

These cases teach several practical lessons for anyone planning their estate:

Key Takeaways:

• Document your reasons: Mrs Jackson had written a letter explaining her reasons for disinheriting Heather. While the Supreme Court awarded Heather something, the detailed documentation of Mrs Jackson’s reasoning was crucial in limiting the award to just £50,000 from a £486,000 estate.
• A well-structured will is essential: A professionally drafted will with clear, explicit language about the disinheritance is far harder to challenge than a DIY will with vague or ambiguous wording. The cost of professional drafting is negligible compared to the legal fees of a contested estate.
• Courts can adjust, but they respect your wishes: The Supreme Court signalled clearly that it will not routinely redistribute estates simply because a child feels aggrieved — there must be genuine financial need.
• Consider alternatives: Had Mrs Jackson placed her assets in a discretionary trust with Heather as a potential beneficiary, the litigation might never have happened — and Mrs Jackson’s charitable wishes could still have been fulfilled through the trustees’ discretion. A trust arrangement can achieve the same practical outcome as disinheritance with a fraction of the legal risk.

The Role of Media Coverage

Media coverage of disinheritance cases — particularly Ilott v The Blue Cross — has raised public awareness of both the 1975 Act and the limits of testamentary freedom. However, media reporting often sensationalises these cases, giving the misleading impression that wills are routinely overturned.

In reality, the vast majority of wills are administered without any challenge. And where challenges are brought, they frequently settle before reaching court — often because the cost of litigation (which is borne by the estate) makes settlement the pragmatic choice for all parties. Every pound spent on legal fees is a pound that doesn’t go to the beneficiaries you chose.

The real lesson from these cases is not that disinheritance is impossible, but that it requires careful planning, clear documentation, and specialist advice to be done effectively. As Mike Pugh puts it: “Not losing the family money provides the greatest peace of mind above all else.”

Preparing for the Future: Best Practices

Whether you choose to disinherit a child, use a trust to control distributions, or simply make an unequal will, the principles of good estate planning remain the same. Here are the best practices to ensure your plan stands the test of time.

Regular Will Reviews

Your will should be reviewed every three to five years — and immediately after any significant life event such as a marriage, divorce, birth, death, or major change in financial circumstances. Remember that marriage automatically revokes an existing will in England and Wales, and failing to update your will after a divorce could leave your estate distributed in ways you never intended.

Regular reviews also ensure your will reflects current tax thresholds and legislation. The inheritance tax nil rate band has been frozen at £325,000 since 2009 — and is set to remain frozen until at least April 2031. With the average home in England now worth around £290,000, more families than ever are being caught by IHT. What seemed like a comfortable estate plan five years ago may now have significant tax implications. From April 2027, inherited pensions will also become liable for IHT — another reason to keep your planning under regular review.

Documenting Your Decisions

If you’re making a decision to disinherit or reduce a child’s share, document your reasoning thoroughly — but do so in a separate confidential letter or statement, not in the will itself. Remember: your will becomes a public document once the Grant of Probate is issued and anyone can obtain a copy from the Probate Registry. A confidential letter of wishes or statement of reasons provides the court with evidence of your intentions without airing family matters in the public record.

This documentation should be dated, signed, and ideally witnessed. Review and update it whenever you review your will, to show that your decision was consistent and considered over time — not a hasty reaction to a single disagreement. A pattern of consistent documentation over several years is far more compelling to a court than a single letter written at the time the will was signed.

Ensuring Clarity and Transparency

Clarity in your will is your strongest defence against a successful challenge. Every provision should be drafted in clear, unambiguous language. Where you’re excluding someone, say so explicitly. Where you’re including a trust, ensure the trust deed clearly defines the trustees’ powers and the class of potential beneficiaries.

Transparency with your family — to the degree you’re comfortable with — can also reduce the risk of disputes. A family that understands your reasoning (even if they disagree with it) is less likely to litigate than one that is blindsided by the contents of your will.

Ultimately, good estate planning is about more than just writing a will — it’s about building a comprehensive plan that protects your assets, reflects your wishes, and gives your family the best chance of moving forward without conflict. Keeping families wealthy strengthens the country as a whole, and it starts with a plan. If you’re unsure where to start, a specialist estate planner can help you assess your situation and build a plan tailored to your circumstances.
