Executor of a will: roles, responsibilities and legal powers explained

An executor of a will is the person (or organisation) legally appointed to carry out the instructions in someone’s will after they die. As the executor, you become a personal representative under the Administration of Estates Act 1925 and Trustee Act 2000 Section 1, with fiduciary duties to beneficiaries and creditors. Your role includes locating assets, paying debts, managing inheritance tax, applying for probate, and distributing the estate fairly. This guide explains what executors of a will do, their legal responsibilities and powers, eligibility, and when you need professional help, and when it may be advisable to consult a solicitor specialising in probate.

Key Takeaway: What is an executor of a will and what are their main responsibilities?

• An executor of a will is a legal representative appointed to manage the deceased’s estate, apply for probate, pay debts and taxes, and distribute assets to beneficiaries according to the will’s instructions.
• Executors have significant powers after probate is granted but face strict fiduciary duties to act in beneficiaries’ best interests, not their own, and can face personal liability for mistakes.
• Simple estates may be manageable without a solicitor, but professional help is essential for complex estates, family disputes, inheritance tax, or when you lack confidence in legal processes.

Consult a wills and probate solicitor (specialising in estate administration and probate law) if your estate is complex, beneficiaries disagree, assets are scattered, or inheritance tax is due.

Who can act as an executor?

Almost anyone over 18 with mental capacity can act as an executor, but being legally eligible doesn’t mean everyone should.

Under UK law, there are minimal legal barriers to becoming an executor of a will:

• You must be at least 18 years old and have the mental capacity to make decisions about estate administration (assessed under the Mental Capacity Act 2005).
• You can renounce (decline) the role at any time before accepting it or carrying out duties, which is why many people nominated as executors step back after the person dies.
• Family members, friends, professionals (solicitors, accountants), and corporate entities like banks can all serve.

However, being legally eligible isn’t the same as being practically suitable. The best executors combine trustworthiness, organisational ability, and either financial knowledge or willingness to seek expert help. If you lack these qualities, renouncing in favour of someone more capable (or a professional) avoids months of stress and potential legal liability. Most people appoint 1–2 executors (ideally family) but name a solicitor as a backup in case the main executor cannot act.

Can an executor also be a beneficiary?

Yes, it’s normal and legally permissible for an executor to also inherit from the estate, but fiduciary duties must be upheld fairly.

It’s extremely common for the main beneficiary (spouse, adult child) to also be the executor. The law permits this because many people want a trusted family member to manage their affairs. However, being both creates a potential conflict: your personal interest in inheriting must never override your fiduciary duty to treat all beneficiaries fairly.

Under equity law, executors must act in the best interests of all beneficiaries, not themselves. Courts treat this principle as fundamental to trust and probate law. In the landmark case Rukhadze v Recovery Partners GP Ltd [2025] UKSC 10, the UK Supreme Court reinforced the “no-profit rule”: fiduciaries cannot make unauthorised gains from their position.

If you’re both executor and beneficiary, disclose any personal interest in writing to all beneficiaries, keep detailed records of all decisions, and consider getting written agreement from beneficiaries before making major choices (like selling property or retaining professional advisers). If conflict becomes serious, a professional executor or solicitor-led administration protects everyone.

What does an executor do? (Duties & powers)

As executor, you manage the entire estate from death until final distribution, a responsibility that spans two distinct phases with different duties and powers.

Before probate is granted

Your duties:

• Locate and verify the latest will.
• Calculate inheritance tax liability.
• Check for funeral wishes and arrange the funeral.
• Gather a complete inventory of assets and liabilities.
• Notify banks and relevant organisations of the death.
• Apply for a grant of probate from HM Courts & Tribunals Service.
• Decide whether DIY probate is realistic or professional help is essential.

After probate is granted

Your duties:

• Sign off on final accounts.
• Complete inheritance tax returns.
• Access and manage all estate assets.
• Sell property if instructed by the will.
• Keep meticulous records of every transaction.
• Collect funds from banks and investment firms.
• Ensure each beneficiary receives their correct share.
• Distribute the remaining estate according to the will.
• Pay all debts (funeral costs, mortgages, loans, final tax bills).
• Transfer land and property via an assent under Administration of Estate
• Your underlying legal duty is fiduciary responsibility: you ms Act 1925 Section 36.ust act in the best interests of the estate and all beneficiaries, not yourself. Breach of this duty under the Trustee Act 2000 may expose you to personal liability.

What an executor cannot do (Legal limits & restrictions)

Executors have significant power, but that power is strictly limited by law, the will’s terms, and fiduciary duty.

What you cannot do:

• Change or alter the will.
• Borrow against estate assets for personal gain.
• Distribute assets before paying all debts and taxes.
• Ignore known debts to favour certain beneficiaries.
• Give yourself or others unauthorised gifts from the estate.
• Act contrary to the will’s instructions, even if beneficiaries request it.
• Sell property below market value to benefit yourself or a favoured person.
• Retain estate funds for your own use, even temporarily, without permission.
• Act in your own self-interest rather than the estate’s and beneficiaries’ interests.
• Unreasonably delay distribution beyond the “executor’s year” (12 months from death).

What if the executor cannot or will not act?

If an executor dies, lacks capacity, or refuses the role, there are clear legal pathways, but delays are common and can frustrate beneficiaries.

Before probate: A named executor can renounce via a formal Deed of Renunciation, signed before or immediately after death. Once renounced, the next executor named in the will steps in. If no one renounces but no one applies for probate within a reasonable time, the courts may allow a beneficiary or creditor to apply instead. If all executors renounce or cannot act, the estate falls under intestacy rules, and a beneficiary (usually the closest relative) must apply for Letters of Administration.

After probate: If an executor dies after probate is granted, the remaining executors continue, and they alone administer the estate; the deceased executor’s role does not automatically pass on. If the sole executor dies, beneficiaries must apply to court (complex and slow) to have a new executor appointed.

If an executor refuses to act but doesn’t renounce, beneficiaries can apply for “Power Reserved” (naming an alternative executor to act while the original executor reserves their right to step in later). This avoids probate delays.

If an executor acts incompetently or breaches fiduciary duty, beneficiaries can petition for their removal under Section 50 of the Administration of Justice Act 1985, but this requires court evidence of unfitness.

FAQs

Can an executor change or challenge the will? No. Your duty is to carry out the will as written, even if you disagree with it. Challenging the will requires a formal court claim by a beneficiary or interested party—never the executor unilaterally.

Can an executor take everything from the estate? Absolutely not. Executors have no entitlement to the estate beyond what the will specifies. Taking assets not authorised by the will is theft and breach of fiduciary duty, exposing you to criminal prosecution and civil liability.

What if no executor is named in the will? The estate is treated as intestate. The probate court appoints an administrator (usually the closest relative) who follows intestacy rules rather than the will’s terms, unless the will existed but named no executor.

Being an executor of a will is a serious legal responsibility requiring fiduciary duty, meticulous record-keeping, and sound decision-making. Understanding your duties, powers, and limits protects both the estate and your personal interests. Professional guidance ensures compliance and peace of mind.

This guide provides general legal information and should not replace advice from a qualified solicitor. Every estate is unique, and professional guidance protects your interests and ensures compliance with strict legal requirements.
