Wills vs Trusts: Which Estate Planning Tool Do You Need?

Planning for the future means understanding the difference between wills and trusts. Getting this right is essential to making sure your assets are protected and pass to the people you choose — not lost to inheritance tax (IHT), care fees, or family disputes.

A will is a legal document that sets out who inherits your assets after you die. It only takes effect on death and must go through the probate process. A trust, on the other hand, is a legal arrangement where you (the settlor) transfer assets to trustees, who hold and manage them for your chosen beneficiaries. A lifetime trust can take effect immediately — meaning it can protect your assets while you’re still alive.

Choosing between wills and trusts can feel overwhelming, especially when your family’s security is at stake. In this article, we explain the key differences between these two estate planning tools under English and Welsh law, so you can make an informed decision about which approach — or combination — best protects your family.

Understanding the Basics of Wills and Trusts

To make sure your assets go where you want them — and are properly protected along the way — you need to understand how wills and trusts work differently. Estate planning is about far more than writing down who gets what. It’s about protecting your family’s financial future against real, measurable threats.

What is a Will?

A will is a testamentary document that sets out how you want your estate distributed after your death. It allows you to name beneficiaries, appoint executors to administer your estate, and — crucially for parents — nominate guardians for minor children. However, a will only takes effect after you die and must go through the probate process. During probate, all sole-name assets are frozen — bank accounts, property, investments — and your will becomes a public document that anyone can obtain a copy of for a small fee once the Grant of Probate has been issued.

What is a Trust?

A trust is a legal arrangement — not a legal entity — where you (the settlor) transfer assets to trustees, who hold the legal ownership and manage those assets for the benefit of your named beneficiaries. England invented trust law over 800 years ago, and it remains one of the most powerful asset protection tools available. There are two primary types based on when they take effect: lifetime trusts (which take effect during your lifetime) and will trusts (which are created by your will and take effect on death). Within these, the most common and protective structure is the discretionary trust, where trustees have absolute discretion over distributions — meaning no single beneficiary has a legal right to the assets. This is the key mechanism that provides protection from care fees, divorce, and creditors.

Key Differences Between Wills and Trusts

Wills and trusts serve different purposes in estate planning. Here’s a comparison of their key characteristics:

Understanding these differences is essential for choosing the right estate planning approach. A will tells people who gets what — but a trust actually protects those assets before, during, and after that transfer. For most homeowning families, the strongest approach is to have both working together.

The Importance of Estate Planning

Estate planning is about far more than deciding who inherits your possessions. It’s about protecting the wealth you’ve built — your home, your savings, your family’s security — from the very real threats of inheritance tax, care fees, probate delays, and family disputes. Not losing the family money provides the greatest peace of mind above all else.

Why You Should Plan Your Estate

A proper estate plan protects your assets and your loved ones from multiple threats. With the right planning, you can:

• Make sure your assets pass to the people you choose — not according to the intestacy rules.
• Reduce or mitigate inheritance tax, which is charged at 40% on everything above the nil rate band (currently £325,000 per person, frozen since 2009 and confirmed frozen until at least April 2031).
• Protect your family home from being sold to fund care fees — currently averaging £1,200-£1,500 per week, with between 40,000 and 70,000 homes sold annually to pay for care.
• Nominate guardians for your children, ensuring they’re looked after by people you trust.
• Ensure your family can access assets quickly after your death, rather than waiting months for the probate process to complete.

Good estate planning advice helps you understand how wills, trusts, Lasting Powers of Attorney (LPAs), and other tools work together. This ensures your plan is comprehensive and tailored to your specific situation.

Consequences of Not Having an Estate Plan

Failing to plan can have serious consequences for your family. These include:

1. Intestacy rules deciding who inherits — your assets may not go to the people you’d choose. For example, under English intestacy rules, unmarried partners receive nothing regardless of how long you’ve been together.
2. Family disputes and legal challenges, which can damage relationships permanently and eat into the estate’s value.
3. A significant inheritance tax bill — with the average home in England now worth around £290,000, even modest estates can be caught by IHT, especially when other assets like pensions (which become liable for IHT from April 2027), savings, and life insurance are added. The nil rate band hasn’t increased with inflation since 2009, which is the number one reason ordinary homeowners are now caught by IHT.
4. Your home being sold to fund care fees because no protection was put in place in advance. In England, if you have capital above £23,250 you’re treated as a self-funder — and care costs can quickly erode a lifetime of savings.

Understanding these risks helps you take action before it’s too late. As the saying goes: plan, don’t panic.

Who Needs a Will?

Every adult in England and Wales should have a will — it’s the foundation of any estate plan. A will is a legal document that sets out how you want your estate distributed after your death, who should administer it, and who should care for your children. While a will alone cannot protect assets from care fees or IHT, it’s still an essential starting point.

Individuals Without Significant Assets

Even if you don’t own property or have large savings, a will serves important purposes. It allows you to appoint an executor — someone you trust to handle your affairs. You can specify who receives personal items, sentimental possessions, or small amounts of money.

Without a will, even a modest estate is distributed according to intestacy rules, which may not reflect your wishes at all. Your estate could go to relatives you barely know, while close friends or an unmarried partner receive nothing. A simple will prevents this.

Parents with Minor Children

For parents with children under 18, a will is absolutely essential. It’s the only legal way to nominate guardians — the people who will raise your children if you and your partner both die. This is arguably the most important decision in any estate plan.

Without a will, the family court decides who cares for your children. This process can be stressful, time-consuming, and may result in your children being placed with someone you would never have chosen.

Those in Blended Families

Blended families — where one or both partners have children from previous relationships — particularly benefit from careful will drafting. Without a will, the intestacy rules could leave children from a previous relationship with little or nothing, while your current spouse inherits most or all of the estate.

A well-drafted will can specify exactly how assets are divided between your current partner and children from all relationships. However, it’s important to understand that a will alone may not fully protect against “sideways disinheritance” — where a surviving spouse later changes their own will and cuts out your children. For that level of protection, a trust (often an interest in possession trust created by the will) is the stronger solution, ensuring the surviving spouse can use the assets during their lifetime while guaranteeing that the capital ultimately passes to your children.

Who Needs a Trust?

Trusts are not just for the rich — they’re for the smart. If you own a home in England and Wales, a trust is likely to be relevant to you. With the average home now worth around £290,000, ordinary homeowning families face real threats from IHT, care fees, and family disputes that a will alone simply cannot address.

High-Net-Worth Individuals

For those with larger estates, trusts are an essential part of tax-efficient planning. The IHT nil rate band has been frozen at £325,000 per person since 2009 and won’t increase until at least April 2031. With the Residence Nil Rate Band at £175,000 (and only available when a qualifying home passes to direct descendants — not nephews, nieces, siblings, friends, or charities), even a married couple with a family home and modest savings can find themselves approaching the combined £1,000,000 threshold. A properly structured irrevocable lifetime trust — such as a Gifted Property Trust — can remove assets from your estate and start the 7-year clock for IHT purposes, potentially saving your family tens or even hundreds of thousands of pounds. It’s worth noting that a revocable trust provides no IHT benefit at all — HMRC treats the assets as still belonging to the settlor.

Those Seeking Privacy

Privacy is a significant benefit of trusts. When a will goes through probate, it becomes a public document — anyone can obtain a copy of it, along with details of the estate’s value. A trust, by contrast, remains entirely private. While all UK express trusts must be registered with HMRC’s Trust Registration Service (TRS), that register is not publicly accessible — unlike Companies House. For families who value discretion — or who have complex personal situations — this privacy can be extremely important.

People with Special Needs Beneficiaries

If you have a loved one with a disability or additional needs, a discretionary trust can be vital. When assets are held in a discretionary trust, no beneficiary has a legal right to them — which means the trust assets should not affect their entitlement to means-tested benefits such as Personal Independence Payment (PIP), Universal Credit, or local authority care funding. Without a trust, an outright inheritance could push them over the capital threshold and disqualify them from the support they need. This type of planning requires specialist advice to get right, but it can make an enormous difference to your loved one’s quality of life.

In short, trusts are beneficial for a wide range of families — from homeowners concerned about care fees, to parents worried about a child’s marriage breaking down, to those planning for a vulnerable beneficiary. Understanding the benefits helps you make better estate planning choices.

Advantages of Having a Will

A will is the cornerstone of any estate plan. While it has limitations compared to a trust, it serves several vital functions that a trust alone cannot replace.

Simplicity and Cost-Effectiveness

A will is generally simpler and less expensive to create than a trust. For straightforward estates, a professionally drafted will provides a clear, legally binding record of your wishes at a modest cost.

Key benefits of simplicity and cost-effectiveness include:

• Lower initial cost compared to setting up a trust
• Straightforward process — your solicitor or estate planning specialist takes instructions and drafts the document
• Suitable as a starting point for everyone, regardless of estate size

Control Over Asset Distribution

A will gives you direct control over who inherits your assets. You can leave specific items to named individuals, make charitable gifts (which can reduce the IHT rate to 36% if 10% or more of the net estate is left to charity), and ensure your estate is divided exactly as you wish. Without a will, the intestacy rules of England and Wales dictate who inherits — and the results are often surprising. For example, unmarried partners receive nothing under intestacy, no matter how long the relationship.

By clearly setting out your wishes in a will, you ensure your assets pass according to your instructions rather than default legal rules.

Naming Guardians for Children

If you have children under 18, a will is the only legal way to nominate who should look after them if both parents die. No trust can do this — it must be done in a will. This alone makes a will essential for every parent.

Naming guardians in a will:

• Ensures your children are cared for by someone you trust and have chosen
• Provides peace of mind that your children’s future is secure
• Prevents the family court from making this decision for you — a process that can be distressing for the whole family

Advantages of Having a Trust

A trust goes far beyond what a will can achieve. While a will simply distributes assets on death, a trust provides ongoing protection for those assets — both during your lifetime and for generations to come. It’s one of the most effective estate planning tools available under English law, which invented the concept over 800 years ago.

Bypassing Probate Delays

One of the most significant advantages of a trust is that trust assets bypass the probate process entirely. When someone dies, all sole-name assets are frozen until a Grant of Probate is issued — a process that currently takes 3-12 months for the full administration, and often longer when property needs to be sold (9-18 months is not unusual). During this time, your family cannot access those assets — meaning they may struggle with everyday expenses at the worst possible time. Trust assets, by contrast, are already held by the trustees, who can act immediately on the settlor’s death with no court involvement and no delays.

Flexibility in Asset Management

A discretionary trust gives trustees the flexibility to respond to changing circumstances. Unlike a will, which gives a fixed instruction at a single point in time, a discretionary trust allows trustees to decide how and when to distribute assets to beneficiaries over the trust’s lifetime (up to 125 years under current UK law). This means they can respond to changes in beneficiaries’ financial situations, health needs, marital status, or tax circumstances — exactly the kind of adaptability that a modern family needs. Trustees are guided by a letter of wishes from the settlor, which sets out the settlor’s intentions without being legally binding, keeping the trust flexible while ensuring the settlor’s views are considered.

Protection from Care Fees, Divorce, and Creditors

Perhaps the most powerful advantage of a properly structured discretionary trust is asset protection. Because no single beneficiary has a legal right to the trust assets, those assets are protected from:

• Care fees: If a beneficiary needs residential care (currently averaging £1,200-£1,500 per week), assets held in a discretionary trust are not their personal capital and should not be assessed by the local authority — provided the transfer was made well in advance and not for the purpose of avoiding care fees. There is no fixed time limit for deprivation of assets (unlike the 7-year IHT rule), but the longer the gap between the transfer and the need for care, the harder it is for a local authority to argue the transfer was deliberate deprivation.
• Divorce: With the UK divorce rate at around 42%, a child’s inheritance held in a discretionary trust cannot be claimed by their ex-spouse in divorce proceedings. As the concept goes: “What house? I don’t own a house” — because the trustees own it, not the beneficiary.
• Creditors and bankruptcy: Assets in a discretionary trust are not owned by any individual beneficiary, so they’re generally not available to that beneficiary’s creditors.

These protections are simply not available with a will alone, which passes assets outright to beneficiaries — leaving them exposed to all of these threats.

Potential Drawbacks of Wills

While a will is an essential starting point, it has significant limitations that every homeowner should understand. Relying on a will alone leaves your assets exposed to several risks.

The Probate Process and Delays

The biggest practical limitation of a will is the probate process. Before your executors can distribute anything, they must apply for a Grant of Probate from the Probate Registry, gather all asset information, pay any IHT due, and settle debts. Only then can they begin distributing assets to beneficiaries.

The typical probate timeline involves:

• Gathering financial information and valuing the estate
• Applying for the Grant of Probate — currently taking around 4-8 weeks for straightforward cases
• Paying inheritance tax (which must be paid before the Grant is issued for estates above the nil rate band — often requiring executors to borrow or use the Direct Payment Scheme)
• Settling debts and liabilities
• Distributing the remaining assets to beneficiaries

The full process typically takes 3-12 months, and if property needs to be sold, it can stretch to 9-18 months or more. During this entire period, all sole-name bank accounts, investments, and property are frozen. Your family may not be able to access funds they need for everyday expenses — a situation that causes real hardship and stress at what is already a difficult time.

Public Record Disclosure

Another significant drawback is that once a Grant of Probate is issued, your will becomes a public document. Anyone can apply to the Probate Registry and obtain a copy for a small fee. This means the details of your estate — what you owned, who inherits, and how much — are available for anyone to see.

Public disclosure can lead to:

1. Unwanted approaches from claims management companies or financial firms targeting beneficiaries
2. Family disputes when relatives discover the terms of the will
3. Potential targeting of beneficiaries who are known to have received a large inheritance

Understanding these limitations helps you decide whether a will alone is sufficient or whether adding a trust would better protect your family. For most homeowning families, the answer is both.

Potential Drawbacks of Trusts

Trusts are powerful planning tools, but they do require some investment and ongoing attention. It’s important to understand these aspects so you can weigh them against the substantial benefits.

Higher Initial Setup Costs

Setting up a trust costs more than a simple will. A straightforward trust from a specialist provider starts from around £850, with more complex arrangements typically costing £850-£2,000 or more depending on the assets involved and the number of trust structures needed. However, it’s worth putting this cost in perspective.

Here’s how trust costs compare to the risks they protect against:

When you compare the cost of a trust to the potential costs of care fees or inheritance tax, it’s one of the most cost-effective forms of protection available. A trust typically costs the equivalent of just one or two weeks of care — a one-time fee versus ongoing costs that continue until assets are depleted to £14,250.

Complexity in Management

Trusts do involve ongoing responsibilities for trustees. These include maintaining proper records, registering the trust with HMRC’s Trust Registration Service (within 90 days of creation — a requirement for all UK express trusts), and filing trust tax returns (SA900) when required. Trustees must also act in accordance with the trust deed and in the best interests of beneficiaries.

However, for most family trusts — particularly those holding a family home where the settlor continues to live in the property — the day-to-day management is minimal. The trustees don’t need to do anything on a daily or weekly basis. The key responsibilities are administrative and periodic, typically amounting to a few hours per year. Many specialist firms, including MP Estate Planning, provide ongoing support and guidance to trustees to help them fulfil their duties with confidence.

The law — like medicine — is broad. You wouldn’t want your GP doing surgery. Trust planning requires specialist knowledge, so working with a firm that focuses specifically on trusts rather than a general high-street solicitor makes a real difference to the quality and effectiveness of your plan.

When You Might Need Both a Will and a Trust

For most homeowning families, the strongest estate plan combines both a will and a trust. Each serves a different purpose, and together they provide comprehensive protection that neither can achieve alone.

A will handles things only a will can do — such as appointing guardians for children and distributing any assets not held in trust. A trust protects the assets that need protecting — typically your home and other valuable property. Let’s look at the situations where this combined approach is most important.

Complex Family Situations

In blended families, second marriages, or where there are vulnerable dependants, having both a will and a trust is particularly important. A will names guardians for minor children and acts as a “safety net” for any assets not already in trust. A trust — often a discretionary trust or an interest in possession trust created by the will — protects assets for specific beneficiaries over the long term.

For example, if you have children from a previous marriage and a current spouse, a will trust can give your spouse the right to live in the family home for their lifetime (an interest in possession), while ensuring the property ultimately passes to your children rather than being lost to your spouse’s new partner or their family. This prevents what’s known as “sideways disinheritance” — one of the most common estate planning failures in blended families.

Diverse Asset Types

Families with different types of assets — such as a family home, buy-to-let properties, investments, and business interests — often benefit from having both a will and one or more trusts. Different assets may require different trust structures: a Family Home Protection Trust for the main residence, a Settlor Excluded Asset Protection Trust for investment properties, or a Life Insurance Trust to keep a life insurance payout outside the estate for IHT purposes (which is typically free to set up).

A will then covers everything else — personal possessions, remaining bank balances, and any assets acquired after the trusts were established. Together, the will and trusts form a complete, coordinated plan that addresses every asset and every threat.

Understanding how a will and a trust complement each other helps you create a plan that truly protects your family. At MP Estate Planning, we help families put together exactly this kind of coordinated approach, tailored to their unique circumstances.

How to Decide Between a Will and a Trust

Choosing between a will and a trust — or deciding you need both — depends on your specific assets, family situation, and what you’re trying to protect against. Here’s how to think it through.

Assessing Your Assets

Start by taking stock of what you own. Your home is likely your most valuable asset — and with the average home in England now worth around £290,000, even a modest property can push your estate towards or above the IHT threshold. Consider the total value of your estate: property, savings, investments, pensions (which become liable for IHT from April 2027), and any life insurance policies not already written in trust. If your total estate exceeds £325,000 (single) or could exceed £650,000 (married couple), or if you own property you want to protect from care fees or divorce, a trust should be part of your plan.

Considering Your Family Dynamics

Your family situation is equally important. Think about whether you’re married or in a civil partnership, whether you have children from different relationships, whether any beneficiaries are vulnerable or have additional needs, and whether any of your children are going through — or could go through — a divorce. With the UK divorce rate at around 42%, the risk of a child’s inheritance being claimed by an ex-spouse is very real. A discretionary trust protects against this; a will does not.

By honestly assessing your assets and family dynamics, you’ll quickly see whether a will alone is sufficient or whether a trust — or a combination of both — is needed to properly protect your family. We provide specialist estate planning advice tailored to your individual circumstances, including a comprehensive threat analysis using our Estate Pro AI system that examines 13 potential risks to your estate.

Professional Help in Estate Planning

Estate planning — particularly when trusts are involved — requires specialist knowledge. Getting the right professional help is the difference between a plan that actually protects your family and one that falls apart when it’s needed most.

Seeking Professional Guidance

Speaking with a specialist trust and estate planning professional gives you tailored estate planning advice based on your specific situation. Whether you need a will, a lifetime trust, or a combination of both, a specialist can identify the threats to your estate and recommend the right structures. General high-street solicitors handle a wide range of legal work — conveyancing, family law, litigation — and may not have the in-depth trust knowledge needed for effective asset protection planning.

Selecting the Right Expert

When choosing an estate planning specialist, look for someone who focuses specifically on trusts and inheritance tax planning rather than offering estate planning as one of many services. Key things to look for include: published pricing (MP Estate Planning is the first and only company in the UK that actively publishes all prices on YouTube), specialist trust law knowledge, a clear process for explaining your options in plain English, and ongoing support after your trust is set up. You should feel confident that your adviser understands the difference between a discretionary trust and a bare trust, can explain the relevant property regime, and knows how to structure a trust that provides real protection — not just a document that looks impressive but offers no practical benefit.

With the right specialist help, you can create a comprehensive estate plan that gives you and your family genuine peace of mind — because keeping families wealthy strengthens the country as a whole.
