Essential Legal Documents for Later Life

Written by James Tyrrell · Reviewed by Anthony Dalton · Last reviewed 16 March 2026

Most people have a will. Far fewer have a Lasting Power of Attorney, an advance decision, or up-to-date pension nominations. Yet without these documents, your family could face months of legal delays, unexpected costs, and decisions made by strangers. This guide covers the essential legal documents everyone should have in place — not just in later life, but ideally well before they are needed.

Lasting Powers of Attorney

A Lasting Power of Attorney (LPA) is arguably the single most important legal document you can create during your lifetime. There are two types, and ideally you should have both:

Each LPA costs £92 to register with the Office of the Public Guardian. Without an LPA, your family would need to apply to the Court of Protection for a deputyship order — a process that costs over £1,000 and can take many months. Crucially, you must create an LPA while you still have mental capacity. Once capacity is lost, it is too late.

A Valid Will

While an LPA protects you during your lifetime, a will protects your family after your death. A valid will ensures that your assets are distributed according to your wishes, rather than according to the intestacy rules (which apply if you die without a will).

Your will should cover:

• How your estate (property, savings, investments, personal possessions) should be divided among your beneficiaries
• The appointment of executors who will administer your estate
• Guardianship of any dependent children
• Any specific gifts to individuals, charities, or organisations
• Trusts for vulnerable beneficiaries or minor children

Review your will regularly and update it after significant life events such as marriage, divorce, the birth of grandchildren, or a substantial change in your financial circumstances. An outdated will can cause as many problems as having no will at all.

Advance Decision (Living Will)

An advance decision — sometimes called a living will — allows you to record specific medical treatments that you do not want to receive in the future, in case you later lose the capacity to make or communicate those decisions yourself. Unlike a Health and Welfare LPA, which gives someone else the authority to make decisions on your behalf, an advance decision is a direct instruction from you about your own care.

An advance decision can cover any medical treatment, but it is most commonly used for:

• Refusing life-sustaining treatment in certain circumstances (such as a persistent vegetative state)
• Refusing specific treatments such as blood transfusions, CPR, or artificial ventilation
• Setting conditions under which certain treatments should or should not be given

To be legally binding, an advance decision that refuses life-sustaining treatment must be in writing, signed, witnessed, and must include a specific statement that the decision applies even if your life is at risk. Other advance decisions do not need to be in writing to be legally valid, but putting them in writing is strongly recommended to avoid disputes.

If you have both an advance decision and a Health and Welfare LPA, be aware that a later-made LPA giving your attorney authority over life-sustaining treatment will override an earlier advance decision on the same matter. It is essential that these documents are consistent with each other.

Pension Death Benefit Nominations and Life Insurance

Many people do not realise that their pension and life insurance may not be covered by their will. Most workplace and personal pensions allow you to nominate who should receive any death benefits — including any lump sum payable on your death and, in some cases, an ongoing pension for a spouse or dependant.

Key points to consider:

• Pension death benefit nominations — these are usually separate from your will. Pension trustees have discretion over who receives death benefits, but they will normally follow your expressed wishes. Review your nominations regularly, especially after a change in relationship status
• Life insurance policies — check whether your policy is written in trust. If it is, the payout goes directly to the named beneficiaries without passing through your estate, which can speed up payment and potentially reduce inheritance tax liability
• Employer death-in-service benefits — many employers offer a death-in-service benefit (typically a multiple of your salary). Ensure your nomination form is up to date with your employer's HR department

Funeral Plans and Letters of Wishes

While not strictly legal documents in the same way as a will or LPA, funeral plans and letters of wishes play an important practical role in later-life planning:

• Funeral plan — a pre-paid funeral plan locks in today's prices and ensures your funeral is arranged according to your wishes without placing a financial burden on your family. Since 29 July 2022, funeral plan providers in the UK must be regulated by the Financial Conduct Authority (FCA)
• Letter of wishes — a non-binding document that provides guidance to your executors and attorneys about your preferences. It can cover funeral wishes, how you would like your personal possessions distributed, messages to family members, and any other guidance that does not fit neatly into a formal legal document

A letter of wishes is particularly useful alongside an LPA, as it can give your attorneys additional context about your values, preferences, and priorities that may help them make decisions that are truly in your best interests.

Later Life Legal Documents: Complete Checklist

The documents outlined above form a comprehensive later-life planning toolkit. Here is a summary checklist:

• Property and Financial Affairs LPA — ensures someone you trust can manage your money and property
• Health and Welfare LPA — ensures someone you trust can make care and medical decisions
• A valid, up-to-date will — ensures your estate goes to the people you choose
• Advance decision (if appropriate) — records specific treatments you wish to refuse
• Pension death benefit nominations — ensures your pension benefits go to the right people
• Life insurance review — check policies are in trust and nominations are current
• Funeral plan or written wishes — reduces burden on your family and ensures your preferences are known
• Letter of wishes — provides helpful guidance to your executors and attorneys

None of these documents need to be created all at once. However, the two types of LPA and a valid will should be treated as priorities, as these are the documents that carry the most significant legal weight and are the most difficult (or impossible) to put in place after the fact.
