Lottery Winner Will Guide: How to Protect Your Family and Estate

A major lottery win can change the size and complexity of your estate overnight. An old will may still be legally valid while no longer reflecting the family, assets or decisions you now need to plan for.

A current, properly executed will can set out who inherits, who administers the estate, how younger beneficiaries are provided for and what should happen to property, investments, businesses, charities and personal gifts.

Quick answer

Should a lottery winner make a new will?

A major lottery winner should review any existing will promptly after the prize has been confirmed.

A new will is not automatically required simply because you won, but the old document may no longer suit a much larger or more complex estate. New property, investments, beneficiaries, charitable plans, trusts and tax considerations can all justify a professionally drafted update.

The purpose

Why does a lottery winner need a will?

A will is not simply a list of who gets the money. It is the legal foundation for how the estate should be managed after death.

You choose the beneficiaries

You can provide for family, an unmarried partner, friends, charities and anyone else you deliberately wish to include.

You appoint the executors

You choose the people or professionals responsible for identifying assets, settling liabilities and distributing the estate.

You protect younger beneficiaries

A carefully drafted will can use trusts and trustees rather than leaving a large inheritance outright at the earliest legal age.

You can nominate guardians

Parents can record who they want to care for children under 18 if both parents die.

You can support charities

Specific gifts or a share of the estate can be left to causes that matter to the winner.

You reduce uncertainty

Clear instructions make it less likely that relatives are left guessing, arguing or relying entirely on intestacy law.

A lottery win does not require a special type of “lottery will”. It requires a robust will designed around a suddenly larger and potentially more complex estate.

Why a £5 million estate needs more thought than a £50,000 estate

The legal principles are the same, but the practical consequences are much larger.

More assets and structures

A winner may acquire several properties, investment portfolios, businesses, overseas assets or trusts. Executors need enough authority and skill to manage them.

Greater tax exposure

The £325,000 nil-rate band and possible residence nil-rate band can be small compared with a multimillion-pound estate. Exemptions and reliefs require careful, individual advice.

More people may expect help

Relatives, friends and charities may believe they were promised something. A clear will and accurate records can reduce ambiguity.

Young beneficiaries face greater risk

Receiving £20,000 at 18 is different from controlling millions. Trustees, access ages and guidance may become central to the plan.

Liquidity can be misleading

An estate may be valuable but hold much of that value in property or private investments. Executors may need flexibility rather than being forced into quick sales.

Privacy and security matter

The will becomes a public document after probate is granted in England and Wales, so confidential detail is often better placed in a separate letter of wishes where appropriate.

No valid will

What happens if a lottery winner dies without a will?

The estate is distributed under intestacy rules. Those rules follow family relationships—not personal promises or assumptions.

With a valid will

  • You choose beneficiaries
  • You appoint executors
  • You can nominate guardians
  • You can create trusts
  • You can include friends and charities
  • You can explain personal wishes separately
  • You retain far greater control

Without a valid will

  • The law determines who inherits
  • An unmarried partner has no automatic entitlement
  • Friends and charities receive nothing automatically
  • Stepchildren are not automatically included unless adopted
  • Children’s inheritances follow the default rules
  • Family disputes may become more likely
  • Administrative delay and uncertainty can increase
One of the most serious risks is assuming that a long-term unmarried partner will “obviously” inherit. That is not how intestacy operates in England and Wales.
Core provisions

What should a lottery winner’s will include?

The final wording belongs with a qualified solicitor, but these are the issues a winner should expect to discuss.

1

Executors

Who will take legal responsibility for administering the estate?

2

Beneficiaries

Who receives specific gifts, cash sums or shares of the remaining estate?

3

Guardians

Who should care for children under 18 if both parents die?

4

Trustees

Who will manage money held for children or other beneficiaries?

5

Inheritance ages

Should beneficiaries receive money at 18, 21, 25 or under a more flexible trust?

6

Property

How should homes, holiday properties and investment property be treated?

7

Businesses

What happens to shares, control and any family or trading business?

8

Personal gifts

Jewellery, vehicles, collections and sentimental belongings can be addressed.

9

Charities

Named charities can receive a fixed gift, percentage or part of the residue.

10

Backup provisions

What happens if an executor or beneficiary dies before the winner?

England & Wales formalities

What makes a will legally valid in England and Wales?

Good estate planning only works if the will itself is validly made and executed.

You must usually be 18 or over

The person making the will must normally be at least 18 and have the required testamentary capacity.

It must be voluntary and in writing

The will must reflect the will-maker’s own decisions, without coercion or undue influence.

Two witnesses are required

The will-maker signs or acknowledges the signature in the presence of two witnesses, who must both be present at the same time.

The witnesses must sign too

Each witness signs in the will-maker’s presence. The same document must be correctly executed.

Do not use a beneficiary as a witness

A beneficiary, or the spouse or civil partner of a beneficiary, should not witness the will because the intended gift can fail.

Use a codicil or new will for changes

Do not make informal handwritten alterations after execution. A valid codicil uses the same signing formalities, while major changes are usually better dealt with by a new will.

For a multimillion-pound estate, execution errors can be as serious as drafting errors. A private-client solicitor can help ensure the document, witnesses and wider estate plan work together.

Assets that do not always pass under the will

A will is central, but it does not control every asset in every case. The wider estate plan should review:

Jointly owned property

Property held as joint tenants may pass automatically to the surviving owner. A tenancy in common is treated differently.

Pensions and death benefits

Many pension benefits are distributed under scheme rules, nominations and trustee or administrator decisions rather than by the will itself. Separately, from 6 April 2027 most unused pension funds and pension death benefits will be brought into the estate for Inheritance Tax purposes, with specified exceptions.

Life policies written in trust

These may sit outside the estate and pay to named trustees or beneficiaries.

Trust assets

Property already held in trust is governed by the trust terms, not simply by the winner’s will.

Overseas assets

Foreign succession and tax rules may apply. Separate or coordinated wills may be needed.

Digital accounts

Access, ownership and provider terms vary. A secure digital record may help executors find what exists.

Do not assume that naming someone in a will overrides every nomination, joint-ownership arrangement or trust. The documents need to work together.
Family protection

How can a lottery winner protect children?

For many winners, the most important question is not who inherits, but when and under whose supervision.

Guardians

A parent with parental responsibility can name a testamentary guardian in a will. Whether that appointment takes effect immediately can depend on who else has parental responsibility and any relevant court orders.

Trustees

Trustees manage money and property held for children. They should be capable, trustworthy and able to work together.

Access age

Default arrangements may allow control at 18. A professionally drafted will may provide a later age or a discretionary structure where appropriate.

Education and living costs

The trust can be drafted to permit payments for education, housing, health and maintenance before full access.

Vulnerable beneficiaries

Disability, addiction, financial vulnerability or means-tested benefits may require specialist trust and benefits advice.

Fair does not always mean equal

Different needs can justify different arrangements, but decisions should be documented carefully to reduce later disputes.

The aim is not to control children forever. It is to prevent life-changing wealth arriving before they have the maturity, support and structure to handle it.
Partners and blended families

How should a winner protect a spouse or partner?

Family positionMain issuePlanning discussion
Married or civil partnersSpouse exemption may apply, but outright inheritance may not achieve the family’s longer-term aims.Review ownership, tax allowances, children from earlier relationships and what happens on the second death.
Unmarried partnersThere is no automatic inheritance under intestacy.A will, property ownership and nominations should clearly protect the intended partner.
Second marriageAn outright gift to the new spouse can leave children from an earlier relationship dependent on that spouse’s later decisions.Consider appropriate trusts or rights of occupation with specialist advice.
Separated but not divorcedA spouse may still have legal rights and an existing will may remain relevant.Obtain urgent legal advice and do not assume separation alone has resolved succession.
Blended familyBiological children, adopted children and stepchildren may not be treated identically under default law.Name intended beneficiaries precisely and consider competing housing and inheritance needs.
Marriage or formation of a civil partnership will usually revoke an existing will in England and Wales. An important exception can apply where the will was validly made in contemplation of that specific marriage or civil partnership and was intended to survive it. Review the will before or immediately after the change in status.
Estate administration

How should a lottery winner choose executors?

Executors may have to manage millions of pounds, property, investments, tax, businesses, trusts and sensitive family relationships.

Family or trusted friends

They know the winner and family well, but may lack technical experience or become caught in emotional conflict.

Professional executor

A solicitor or trust corporation can add continuity and expertise, but professional fees should be understood in advance.

A mixed team

One trusted person and one professional can combine personal knowledge with technical support, provided they can work together.

Questions to ask before appointing somebody

  • Are they willing to act?
  • Are they organised and financially responsible?
  • Can they remain neutral between beneficiaries?
  • Are they likely to be available and capable when needed?
  • Can they manage complex assets or know when to obtain advice?
  • Have replacement executors been named?
Trust planning

Should lottery winners use trusts in their wills?

Sometimes—but a trust is a legal structure, not a magic shield or automatic tax-saving device.

Children and young adults

A trust can delay outright access or let trustees fund education, housing and wellbeing over time.

Vulnerable beneficiaries

Specialist trusts may help protect a beneficiary who cannot safely manage a large inheritance.

Blended families

A trust can sometimes provide for a spouse during life while preserving capital for children later.

Discretion and flexibility

Discretionary trusts allow trustees to respond to changing needs, although the winner must choose trustees carefully.

Tax and administration

Trusts can have their own tax reporting, charges, costs and administrative burdens.

Letter of wishes

A non-binding letter may guide trustees without placing every personal detail in the public will.

A winner should not transfer money into a trust merely because somebody says it will “avoid tax”. Trust tax depends on the structure, timing, residence and purpose, and the wrong arrangement can create cost and loss of control.
Inheritance Tax context

Does a will remove Inheritance Tax?

No. A will can support sensible planning, but it does not make a large estate tax-free.

For the 2026/27 tax year, the standard nil-rate band is £325,000. A residence nil-rate band of up to £175,000 may also be available when a qualifying home passes to direct descendants. The standard Inheritance Tax rate on the taxable part of an estate is 40%.

The residence nil-rate band starts to taper when the net estate exceeds £2 million, reducing by £1 for every £2 above that threshold. Unused nil-rate bands can sometimes transfer between spouses or civil partners, so a qualifying surviving spouse or civil partner may have combined allowances of up to £1 million, but this is not automatic and the residence conditions still matter.

If the relevant charitable-giving test is met, leaving at least 10% of the appropriate net estate component to charity can reduce the Inheritance Tax rate on that component from 40% to 36%.

Important 2027 change: for deaths on or after 6 April 2027, most unused pension funds and pension death benefits will also be brought within the value of the estate for Inheritance Tax purposes, subject to specified exclusions. A winner reviewing long-term estate planning in 2026 should make sure pension nominations and the will are considered together.
Keep it current

When should a lottery winner update a will?

Immediately after the win

Review whether the existing will still fits the new scale and complexity of the estate.

Marriage or civil partnership

This normally revokes an earlier will unless a specific legal exception applies.

Divorce or separation

Divorce affects provisions for a former spouse, but separation alone may not.

Births and deaths

New children, grandchildren, deaths and changing family responsibilities matter.

Major purchases

New homes, overseas property, businesses and large investments can alter the plan.

Lifetime gifts

Large gifts may change fairness between beneficiaries and create tax-record requirements.

Moving abroad

Residence, domicile and foreign succession law can create cross-border complexity.

At least every five years

Government guidance recommends reviewing a will every five years and after major life changes. A very large estate may justify more frequent professional review.

Will, letter of wishes and lasting power of attorney: what is the difference?

DocumentWhen it operatesWhat it does
WillAfter deathAppoints executors and sets out how the estate should pass.
Letter of wishesUsually after death alongside the will or trustGives non-binding guidance to executors or trustees and can hold personal detail more privately.
Property and financial affairs LPADuring life, once registered and subject to its termsCan allow chosen attorneys to deal with money and property. It may be used while the donor still has capacity if the LPA permits this and the donor agrees.
Health and welfare LPADuring life when the donor cannot make the relevant decisionAllows chosen attorneys to make specified health and welfare decisions, subject to the authority given in the LPA.
A will does nothing during incapacity. A winner who wants trusted people to manage finances or welfare decisions during life should consider registered lasting powers of attorney as a separate part of the plan.
Avoid these mistakes

Common will mistakes after a lottery win

Leaving the old will untouched

A document written for a modest estate may not suit multimillion-pound wealth.

Using vague beneficiary names

Poor identification can create uncertainty, especially in blended or extended families.

Ignoring asset ownership

The will may not control jointly held assets, pensions, trusts or nominated benefits.

Choosing unsuitable executors

A kind relative is not automatically the right person to administer a complex estate.

Making informal changes after signing

Do not simply write amendments onto an executed will. Use a properly executed codicil or, for major changes, make a new will.

Promising gifts without recording them

Verbal promises are difficult to prove and may contradict the final will.

Giving everything outright

Direct gifts may be inappropriate for young, vulnerable or financially inexperienced beneficiaries.

Using trusts without understanding them

Trustees, tax, reporting and costs require proper consideration.

Storing the will badly

Executors need to know that a valid original exists and where it is held securely.

Frequently asked questions

Lottery wills: FAQs

Do lottery winners need a special type of will?

No special legal category of lottery will exists. The winner needs a properly drafted will suited to the value, assets, beneficiaries and complexity of the new estate.

How soon after winning should I make a will?

Arrange a review promptly after the prize is confirmed, but do not sign a rushed document without understanding it. The will should coordinate with the wider financial and tax plan.

Can I write my own will?

Yes. A solicitor is not required for every will, but the document still has to meet the legal requirements for capacity, signing and witnessing. A multimillion-pound estate, trusts, a blended family, a business or overseas assets are strong reasons to obtain specialist drafting advice.

Does marriage cancel my will?

Marriage or civil partnership generally revokes an existing will in England and Wales unless it was validly made in contemplation of that specific marriage or partnership.

Does divorce cancel my will?

No. Divorce or dissolution of a civil partnership does not usually revoke the whole will in England and Wales. Broadly, provisions appointing or benefiting the former spouse or civil partner are treated as if that person had died, unless the will provides otherwise. The remaining document can therefore operate in a way you did not expect, so review it promptly.

Can an unmarried partner inherit?

Yes, when the will provides for them or another legal route applies. They do not inherit automatically under intestacy law merely because they lived with the winner.

Can I leave money to friends?

Yes. A valid will can leave specific gifts or a share of the estate to friends, provided the wording identifies them clearly.

At what age can children inherit?

Under intestacy, a child’s entitlement is generally held until 18. A professionally drafted will or trust can use different arrangements where legally appropriate.

Should I appoint a solicitor as executor?

Not automatically. A professional executor can help with complexity and neutrality but will charge. Some winners use a trusted individual alongside a professional.

Can an executor also inherit?

Yes. An executor can also be a beneficiary, although conflicts and family dynamics should be considered.

Is my will private?

Not permanently. When probate is required, the original will is submitted to the Probate Registry and becomes a public record. Copies can then be ordered through the probate-records service. Highly personal guidance may therefore be better placed in a separate letter of wishes where suitable.

Can I leave money to charity?

Yes. Qualifying charitable gifts are generally exempt from Inheritance Tax. Where the statutory charitable-giving test is met, leaving at least 10% of the relevant net estate component to charity can reduce the Inheritance Tax rate on that component from 40% to 36%.

Should I include funeral wishes?

You can record funeral wishes, but practical arrangements may begin before the will is located or read. If the wishes matter to you, tell the people who are likely to arrange the funeral and consider recording the details separately as well.

How often should I review the will?

GOV.UK recommends reviewing a will every five years and after major life changes such as marriage, separation or divorce, having a child, moving house or the death of an executor. A major lottery win is also an obvious point to review whether the document still fits.

Where should the original will be stored?

Keep it secure with a solicitor, professional storage service or another safe arrangement. Executors should know where the original can be found without being able to alter it.

Can family challenge a lottery winner’s will?

Potentially. A probate dispute may challenge whether the will was properly executed, whether the will-maker had testamentary capacity, knew and approved its contents, or whether undue influence or fraud was involved. Separately, certain eligible people may be able to make a claim for reasonable financial provision from the estate. Those are different legal issues, so specialist advice is important if a dispute is likely.

Does a will cover incapacity?

No. A will takes effect after death. Lasting powers of attorney are the main documents used in England and Wales to appoint trusted people for specified decisions during life.
