We guide families through a clear choice: a do-it-yourself route or professional help from a solicitor. It is possible to make a will without a legal professional, but mistakes are easy to make and expensive to fix.
Safe here means more than having words on paper. It means your wishes actually work in practice when loved ones need them most. Poor drafting, incorrect witnessing, or unclear wording can push an estate into intestacy or spark a dispute that drains the inheritance.
In this guide we explain when a DIY option is practical, when a solicitor is the smarter choice, and how to decide quickly without wading through legal jargon. We cover witnessing rules, executors, property ownership, inheritance tax, and probate delays. We also show how a relatively modest professional check often prevents problems that cost families thousands of pounds.

- Professional advice is important for complex estates, inheritance tax (IHT) planning, and trust provisions.
- Even a short review from a solicitor can prevent disputes that erode the estate years later.
- Store the original safely and tell your executors exactly where to find it.
Why making a will matters for your estate in the UK
Without a clear plan, the intestacy rules of England and Wales step in and dictate who receives your assets. That outcome may bear no resemblance to your wishes — and it cannot account for the people and causes you actually care about.
When we say “estate,” we mean everything you own: your home, savings accounts, investments, pensions, life insurance payouts, and personal possessions. With the average home in England now worth around £290,000, many ordinary families find their combined estate exceeds the inheritance tax nil rate band of £325,000 per person — a threshold that has been frozen since 2009 and is confirmed frozen until at least April 2031. That means IHT at 40% could apply to anything above that figure. A properly drafted will is the first step towards making sure more of your money reaches the people you choose.
What happens if you die without a valid will
The intestacy rules of England and Wales apply a rigid formula. Only married spouses, civil partners and certain close blood relatives can inherit. If you are married with children, your spouse receives the first £322,000 of the estate plus personal chattels, with the remainder split between spouse and children. If you have no spouse and no children, the estate passes to parents, then siblings, then increasingly distant relatives — and ultimately to the Crown as bona vacantia.
Protecting unmarried partners
Cohabiting couples face the greatest risk. No matter how long you have lived together, an unmarried partner has no automatic right to inherit under intestacy. They may have to make a claim under the Inheritance (Provision for Family and Dependants) Act 1975, which is stressful, uncertain, and expensive. A will — ideally supported by wider estate planning such as a lifetime trust or correctly structured property ownership — is the only reliable way to protect an unmarried partner.
Planning for children
Naming testamentary guardians in your will gives the people you trust clear legal authority to care for your children if both parents die. Without this, the court decides — and the outcome may not be what you would have chosen. Where money is being left to children, a trust within the will (a will trust) can ensure funds are managed responsibly until they reach a sensible age, rather than everything landing in their lap at 18. A discretionary will trust is particularly effective here, because no beneficiary has an automatic right to the funds — giving trustees flexibility to distribute according to each child’s needs and circumstances.
“A clear will often shortens probate delays, calms disputes and keeps more of the estate for those you choose — rather than handing a slice to HMRC or solicitors sorting out a mess.”
Simple clarity prevents unintended outcomes. Without it, assets might pass to distant relatives rather than those closest to you, and the people you most wanted to protect could be left with nothing.
can i write my own will or use a solicitor uk: choosing the safest route
Deciding whether to draft at home or get professional help depends on how genuinely simple your situation is. We set out when a DIY path can work, when instructing a solicitor gives real protection, and how to tell the difference.
When a DIY approach can be appropriate
A DIY will is reasonable only for genuinely straightforward circumstances. Think: a single property held as joint tenants with a spouse, a clear set of beneficiaries, no trust provisions needed, no business interests and no overseas assets.
A simple family setup — married couple, no stepchildren, modest savings and equal gifts to children — carries lower risk. Even so, the witnessing formalities must be followed exactly or the will is invalid.
When solicitors are typically safer
Complexity raises risk quickly. Shared property with someone who is not a spouse, blended families, business assets, inheritance tax planning, property held as tenants in common, or potential claims under the Inheritance Act all need expert input.
Solicitors spot gaps that templates miss. What happens if a beneficiary predeceases the testator? How should the residuary estate be distributed? Is a discretionary trust needed to protect vulnerable beneficiaries or shield assets from sideways disinheritance? These questions reduce the chance of disputes and probate delays that can freeze assets for 12 months or longer.
A quick decision check
Use this two-minute checklist:
- Do you own more than one property, or hold any overseas assets?
- Are your beneficiaries clear and straightforward, with no competing claims?
- Do you have dependants with special needs or disabilities?
- Are there business interests, complex investments, or inheritance tax concerns?
If any answer points to complexity, a solicitor review is sensible. Even a short professional check can save legal costs that would otherwise erode the estate — and protect your wishes from challenge. Remember, the law — like medicine — is broad. You wouldn’t want your GP doing surgery.

DIY wills in the UK: benefits, limitations and common mistakes
Paper kits, downloadable templates and online tools look sensible when affairs are simple. Each option saves time and upfront cost. But there are clear limits that people often miss — and the consequences tend to surface at the worst possible moment, when someone has died and the family is already under strain.
- Paper kits — cheap and basic, providing standard wording for simple gifts.
- Templates — editable documents for straightforward gifts and residuary clauses.
- Online tools — guided question-and-answer forms with some prompts, but limited or no legal advice.
Where mistakes crop up
Common drafting faults include vague phrases such as “my house to the kids,” unclear residuary clauses, and no substitution provisions if a beneficiary dies before the testator. Another frequent error is failing to distinguish between property held as joint tenants (which passes automatically by survivorship, outside the will) and property held as tenants in common (which must be dealt with in the will).
Legal formalities matter. The testator must sign the will in the presence of two witnesses, who must each then sign in the testator’s presence. The witnesses — and their spouses or civil partners — must not be beneficiaries, or their gifts will be void. These requirements are not optional. A single mistake can invalidate the entire will, potentially sending the estate into intestacy and generating probate disputes paid for out of the estate itself.
Overlooked assets
People frequently forget to deal with jointly held property, death-in-service benefits, pension death nominations, life insurance policies and overseas property. These items may not pass under the will at all — pensions and life insurance, for instance, usually pass via a separate nomination form — and leaving them unaddressed creates confusion and potential tax liabilities. From April 2027, inherited pensions will also become liable for inheritance tax, making proper planning even more important.

Using a solicitor: how legal advice reduces risk
Good legal advice shapes a will to match your actual family life and financial circumstances — not a generic template designed for the simplest case imaginable. The result is a document that executors can follow without guesswork, and that stands up to challenge.
Tailored drafting for your wishes and finances
Custom wording addresses complex families, trust provisions and business interests properly. A solicitor can draft discretionary will trusts to protect assets from sideways disinheritance in blended families, include interest in possession trusts that let a surviving spouse use the family home while preserving capital for children, and advise on inheritance tax planning — including whether the residence nil rate band (worth up to £175,000 per person, or £350,000 for a married couple) will be available. The RNRB only applies when a qualifying residential interest passes to direct descendants — children, grandchildren and stepchildren — so it is not available if you leave your home to siblings, nieces or friends. That level of detail reduces ambiguity and the chance of costly disputes.
Correct execution and safer signing
A solicitor ensures that the signing and witnessing steps meet the strict requirements of English law. The will is signed in the correct order, the witnesses are independent, and the attestation clause records exactly what happened. Proper execution is one of the biggest safety wins — and one of the most common areas where DIY wills fail.
Professional standards and protection
Solicitors are regulated by the Solicitors Regulation Authority (SRA). That means a duty of care, adherence to professional conduct rules, and compulsory professional indemnity insurance. If a solicitor makes an error in drafting your will, you or your estate have a route to compensation — something no DIY template can offer.
Secure storage and quality markers
Many solicitors’ firms offer secure storage so the original will can be found immediately when needed. Membership of the Law Society’s Wills and Inheritance Quality Scheme (WIQS) signals higher standards and specialist expertise in wills, probate and estate administration.
“Clear legal advice often shortens probate delays and lowers stress for family members — leaving more of the estate for the people who matter.”
- Tailored drafting prevents one-size-fits-all mistakes.
- Correct execution reduces the risk of the will being declared invalid.
- SRA regulation, indemnity insurance and scheme membership add layers of protection.
Legal requirements for a valid will in the UK
A valid will in England and Wales depends on a few clear steps. Get them right and your wishes are protected. Get them wrong and the will may be challenged or declared invalid — pushing the estate into intestacy.
Capacity and voluntariness
The testator must be 18 or older and have testamentary capacity at the time of making the will. This means understanding the nature and effect of the will, knowing the extent of their assets, and appreciating who might reasonably expect to benefit.
They must act freely, without undue influence or coercion.
Pressure from relatives is one of the most common grounds for later challenges.
Where there is any doubt, a solicitor may arrange a capacity assessment — sometimes called following the “golden rule” — by obtaining a letter from a GP or appropriate medical professional to provide evidence that the testator was of sound mind. This is particularly important for older testators or those with early-stage cognitive decline.
Signature and witnesses
The testator must sign the will (or direct someone to sign on their behalf) in the presence of two witnesses, who must each then sign in the testator’s presence.
Witnesses — and their spouses or civil partners — must not be beneficiaries under the will.
If they are, their gift will be void, though the rest of the will remains valid. This is one of the most common traps with DIY wills.
Dating and changes
Always date the will.
Dating establishes which version takes priority if more than one exists, and helps resolve disputes about revocation.
Handwritten changes made after signing — crossings out, added names, marginal notes — do not take effect unless they are properly executed with fresh witnessing.
Informal alterations are simply ignored by the Probate Registry, which can produce outcomes the testator never intended.
Privileged wills for service personnel
Members of the armed forces on active service, and certain seafarers, may make privileged wills with relaxed formalities — for example, oral wills or wills without witnesses.
These follow special rules and the relaxed formalities only apply while the qualifying conditions are met.
“Getting the formalities right at signing protects your wishes and gives those left behind the clarity they need at the hardest time.”
| Requirement | Who it affects | Effect if missing |
|---|---|---|
| Age 18+ and testamentary capacity | The testator | Will may be challenged and declared invalid |
| Two independent witnesses | Witnesses must not benefit (nor their spouses/civil partners) | Gifts to witnesses are voided |
| Clear date | Everyone involved in the estate | Confusion between versions; revocation disputes |
| No informal alterations | Executors and beneficiaries | Changes made after signing are ignored |
| Privileged will exception | Active service personnel and seafarers | Relaxed formalities apply in limited circumstances |
When it is particularly advisable to use a solicitor
Certain family and financial circumstances create risks that a simple template cannot address. We recommend professional help in these situations — not because a DIY will can never work, but because the cost of getting it wrong is disproportionately high.
Shared property with a non-spouse co-owner
The way property is held — joint tenants or tenants in common — fundamentally affects what happens on death. Joint tenancy means the property passes automatically to the surviving co-owner by right of survivorship, regardless of what the will says. Tenants in common means each owner’s share forms part of their estate and passes under their will.
Why this is high risk: getting the ownership structure wrong, or failing to address it in the will, can leave a co-owner without practical rights to the home or accidentally disinherit the people you intended to benefit. A solicitor ensures the title, the will and any trust provisions all work together.
Dependants who cannot care for themselves
Providing for a vulnerable or disabled beneficiary often requires a discretionary will trust. Leaving money outright to someone receiving means-tested benefits such as Universal Credit, Employment and Support Allowance or local authority care funding can disqualify them from that support — effectively handing their inheritance to the state.
Careful planning through a properly drafted discretionary trust keeps funds available for the beneficiary’s comfort and wellbeing without disrupting their entitlements. The trustees have absolute discretion over when and how much to distribute — no beneficiary has a right to income or capital — which is the key protective mechanism.
Blended families and potential claims
Second marriages and children from earlier relationships are one of the most common sources of estate disputes. Without proper planning, a surviving spouse could inherit everything and then leave it all to their own children — cutting out the first family entirely. This is known as sideways disinheritance.
We frequently see situations where the testator’s intentions were perfectly clear in their own mind, but the will did not reflect them properly. Interest in possession trusts, life interest trusts and carefully drafted substitution clauses can all help — but they need specialist drafting. With the UK divorce rate at around 42%, even first marriages can end in ways that affect estate planning, making proper trust provisions all the more important.
Business ownership and complex assets
Businesses need continuity plans. Valuation, inheritance tax reliefs such as Business Property Relief (BPR), shareholder agreements and the practical question of who runs the business after death all make succession planning materially different from distributing personal assets. From April 2026, BPR is capped at 100% for the first £1 million of combined business and agricultural property, with 50% relief on the excess — making professional advice more important than ever.
A solicitor helps determine whether business assets should pass to family members, be sold, or continue within the enterprise — and structures the will accordingly.
Living abroad or holding overseas property
Different legal systems may clash. A will valid in England and Wales may not be recognised abroad, and foreign succession rules — including forced heirship provisions in many European countries — can override your intentions. Probate delays and unexpected tax charges are common where foreign property is involved.
Professional advice co-ordinates cross-border rules, often using separate wills for each jurisdiction, and avoids costly mistakes.
“If any of these situations apply, the fee for professional help almost always proves far cheaper than fixing a costly problem after someone has died.”
| Circumstance | Key risk | How legal help helps |
|---|---|---|
| Shared property | Survivorship confusion; co-owner left without rights | Correct title structure; clear drafting and trust provisions |
| Vulnerable dependant | Loss of means-tested benefits; misdirected funds | Discretionary will trust with tailored trustee powers |
| Blended family | Sideways disinheritance and Inheritance Act claims | Life interest trusts; substitution clauses; dispute reduction |
| Business owner | Continuity, valuation and IHT relief changes | Succession planning; BPR structuring; tailored transfers |
| Overseas property | Conflicting laws; forced heirship; probate delay | Separate jurisdiction wills; cross-border coordination |
How to write or update a safer will: a practical UK checklist
Begin at the kitchen table with a simple asset list and work through decisions that protect loved ones. Plan, don’t panic — taking it step by step makes the process manageable.
Step 1 — List assets
Record your home (and how it is owned — joint tenants or tenants in common), savings accounts, investments, pension funds, life insurance policies, death-in-service benefits, and any business interests. Include overseas property and note any debts or mortgages. This inventory becomes the foundation for everything that follows, and it is exactly what your executors will need.
Choose beneficiaries and record charity gifts
Name beneficiaries using their full legal names and relationship to you. Describe specific gifts (legacies) and residuary shares clearly so executors face no guesswork.
For charity gifts, give the charity’s full name, registered address and Charity Commission registration number to avoid administrative delay. Leaving 10% or more of your net estate to charity can reduce the inheritance tax rate from 40% to 36% — a point worth discussing with your solicitor.
Appoint executors
Always ask the person before naming them. Executors carry significant responsibilities: they apply for the Grant of Probate, collect assets, settle debts, pay any inheritance tax due to HMRC, and distribute the estate to beneficiaries.
We recommend appointing at least two executors. If beneficiaries are under 18 or a trust is included in the will, a minimum of two trustees (who are often the same people as the executors) is essential.
Guardians, trusts and storage
Name testamentary guardians for any children under 18. Consider including a will trust when money must be managed until children reach a sensible age — many parents choose 21 or 25 rather than the default age of 18, using a discretionary trust that gives trustees flexibility over distributions.
Store the original will where it is accessible: with your solicitor, through the Probate Service’s storage facility, or with a specialist document storage provider. Avoid keeping it in a bank safe deposit box — these can be difficult to access after death until legal authority has been obtained, creating a catch-22 situation. Tell your executors exactly where the will is held.
Review, change and revoke
Review your will every three to five years and after any major life event: marriage, divorce, separation, the birth of children or grandchildren, a significant change in assets, or a move abroad. Be aware that marriage automatically revokes an existing will in England and Wales unless the will was made in contemplation of that specific marriage. Divorce does not revoke a will, but it does treat the former spouse as having predeceased — which can produce unintended consequences if the will was not updated.
Minor changes can be made by a properly executed codicil. Larger changes are better handled by making a new will with a clear revocation clause revoking all previous wills and codicils. To revoke a will by destruction, it must be destroyed intentionally by the testator (or someone in their presence and at their direction) with the intention of revoking it — otherwise accidental revival disputes can arise.
“A short, practical checklist now can prevent probate delays of 12 months or more and protect family money when circumstances change.”
| Action | Why it matters | Practical tip |
|---|---|---|
| List assets | Shows executors what they must gather and how it is owned | Include property, pensions, life policies, debts and overseas items |
| Name beneficiaries | Prevents confusion and disputes | Use full legal names and specify clear shares or amounts |
| Record charity gifts | Ensures donations reach the intended charity; may reduce IHT rate | Include charity name, address and Charity Commission number |
| Choose executors | They manage probate and distribution | Ask them first; appoint at least two |
| Storage & review | Ensures quick access and keeps the will current | Store with a solicitor or the Probate Service; review after life changes |

Conclusion
A short, practical review now can save significant money and prevent disputes later.
Most people can write a workable will when their affairs are genuinely simple. Safety rests on three things: clarity of expression, strict compliance with the witnessing formalities, and an honest assessment of whether your situation is really as straightforward as it seems.
DIY suits simple wishes — one home held jointly with a spouse, straightforward gifts and no complicating factors. For blended families, shared property with a non-spouse, business interests, vulnerable dependants, inheritance tax concerns, or any situation involving trusts, seek regulated legal help from a solicitor with specialist estate planning experience.
The real cost is not the professional fee. Mistakes drain estate money through disputes, delays and additional probate work — and by then, it is too late to fix them. Not losing the family money provides the greatest peace of mind above all else.
Next step: list your assets, name the key people, and decide whether to draft and check — or go straight to a professional. That choice often brings lasting peace of mind for the whole family. If your estate involves property, consider whether a lifetime trust alongside your will could provide additional protection from care fees, inheritance tax and family disputes. Trusts are not just for the rich — they’re for the smart.
