What Is an Executor UK (2026)? A Plain-English Guide

An executor (sometimes called a 'personal representative') is the person named in a will to carry out the testator's wishes and administer their estate after death. The role is one of legal duty and personal responsibility. Executors act under the authority of the will, confirmed by the Grant of Probate. Key duties and powers: (1) Applying for a Grant of Probate: the executor applies to the Probate Registry for a Grant of Probate — the formal legal document confirming their authority to administer the estate. Without the Grant, most banks and institutions will not release assets. The application involves completing probate forms, submitting the will, paying the probate fee (£300 for estates over £5,000 plus £1.50 per copy), and paying or arranging to pay any IHT due; (2) Collecting and valuing the estate: the executor must identify, trace, and collect all assets belonging to the estate — bank accounts, property, investments, savings, personal possessions, business interests. They must obtain valuations (at the date of death) for property (a formal RICS or agent's valuation), shares (HMRC quarter-up rule), and other assets. The valuation feeds into the IHT account; (3) Paying debts and liabilities: before distributing the estate, the executor must pay all debts: mortgages; credit cards; personal loans; utility bills; HMRC income tax (up to date of death); IHT (due before the Grant is issued); administration expenses; (4) Distributing the estate: once debts are paid and the Grant obtained, the executor distributes what remains to the beneficiaries according to the will. This includes transferring property (via an Assent to the beneficiary's name), paying cash legacies, and dealing with trusts for minor beneficiaries; (5) Completing tax returns: the executor must submit any outstanding income tax returns for the deceased (including the tax year of death) and may need to file an SA900 estate administration tax return; (6) Keeping proper accounts: the executor should maintain detailed estate accounts, and beneficiaries are entitled to see them.

The rules on who can be an executor are relatively permissive: (1) Age: the executor must be 18 or over at the time of acting. A minor can be named as an executor in the will, but they cannot act until they turn 18. If they are still a minor when the testator dies, administration is deferred or a power of attorney is granted to someone to act until the minor reaches 18; (2) Mental capacity: the executor must have the mental capacity to act. If they lack capacity at the date of the testator's death, administration can be granted to another person; (3) Beneficiaries can be executors: there is no rule preventing a beneficiary from also being an executor. In fact, in most family wills, the executors ARE the beneficiaries (e.g. a spouse as both executor and main beneficiary). An executor-beneficiary must be careful to distinguish between acting in their official capacity (impartially) and their personal interest; (4) Professional executors: solicitors, trust corporations, and banks can act as professional executors. They charge a fee, typically a percentage of the estate value (1–2%). Professional executors are useful for complex estates, where family relationships are likely to cause conflicts, or where there is no suitable person to act; (5) Non-UK residents: a non-UK resident can be an executor, but it may complicate the administration (HMRC compliance; managing property remotely; additional legal requirements); (6) Who CANNOT be an executor: (a) someone under 18; (b) someone who lacks mental capacity; (c) someone who has been convicted of certain criminal offences (the court can remove them under s.116 Senior Courts Act 1981 if there are circumstances rendering it necessary); (7) How many executors: up to 4 executors can be named and appointed. More than 4 can be named in the will as substitute executors (acting if a primary executor cannot or will not act), but only 4 can obtain the Grant at any one time. Most family wills name 2 executors as joint and several — either can act, but both provide a check on the other.

The terms 'executor' and 'administrator' are often confused: (1) Executor: a person named in a valid will to administer the estate. Their authority derives from the will. They apply for a 'Grant of Probate'; (2) Administrator: a person appointed by the Probate Registry to administer an estate where there is no will, or where there is a will but no executor is available. Their authority derives from the court appointment. They apply for 'Letters of Administration' (if no will) or 'Letters of Administration with Will Annexed' (if there is a will but no named executor can act). Collectively, executors and administrators are called 'personal representatives'; (3) When is an administrator appointed instead of an executor? (a) The deceased died without a will (intestate); (b) The will does not name an executor; (c) All named executors have predeceased the testator; (d) All named executors have renounced (formally declined) the role; (e) All named executors are minors or lack capacity; (f) The executor has intermeddled (started to act) but then abandoned the administration — creating a 'chain of representation' issue; (4) Who can be an administrator? Under the Non-Contentious Probate Rules 1987, there is a priority order for who can apply: (a) For intestacy: surviving spouse/civil partner first; then children; then parents; then siblings; then other relatives; (b) For a will without an executor: residuary beneficiaries first; then other beneficiaries; then creditors; (5) Powers: executors and administrators have broadly the same powers to administer the estate — the difference is in the source of authority. Executors derive their power from the will; administrators from the court's letters of administration; (6) Practical difference: naming an executor in a will means administration can begin immediately on death (technically, though in practice the Grant is still needed for most purposes). Administrators must wait for the court appointment — there is a hierarchy and potential delay.

Choosing an executor is one of the most important decisions in making a will. The qualities to look for: (1) Trustworthiness: the executor will have access to all your financial information, assets, and personal records. Trust is the most fundamental requirement; (2) Organisation and attention to detail: estate administration involves forms, deadlines, correspondence with HMRC, banks, insurance companies, and beneficiaries. An organised, methodical person is far better suited than a charismatic but disorganised one; (3) Availability: a full estate administration takes 9–18 months on average (longer for complex estates). The executor needs to be available to respond to correspondence, attend meetings, and make decisions throughout this period; (4) Geographic proximity: while not essential, an executor who lives near the deceased's home and assets will find administration more practical — especially for property-related tasks; (5) Not in conflict of interest: if you have complex family dynamics — an executor who is in dispute with another beneficiary, or who is themselves the residuary beneficiary in competition with other claimants — this can create problems. Consider whether the executor can act impartially; (6) Practical suggestions: (a) Appoint two executors — a primary and a backup. If one executor predeceases you or cannot act, the other can proceed without needing a court appointment; (b) Name a substitute executor in the will for the same reason; (c) Discuss the role with your chosen executors before naming them — an executor who is unaware they have been named can cause delays; (d) A professional executor (solicitor or trust corporation) is worth considering for large, complex, or contentious estates, or where family dynamics make impartiality important; (e) Review the appointment every 5 years — circumstances change.

Yes — executors can be personally liable for mistakes made in administering the estate: (1) Devastavit (waste of the estate): an executor who distributes the estate without first paying all debts, or who makes distributions that reduce the estate below what is owed to creditors, is personally liable to make up the shortfall. This is called 'devastavit' — wasting the estate. The executor must follow the order of priority for paying debts from an estate (funeral expenses; IHT and HMRC; administration costs; secured debts; preferred debts; ordinary debts); (2) IHT liability (IHTA 1984 s.204): if the executor distributes the estate before paying IHT, and there are insufficient assets left to pay the IHT, the executor becomes personally liable for the unpaid IHT up to the value of the estate assets that passed through their hands; (3) Creditor liability: if the executor distributes assets to beneficiaries and a creditor subsequently comes forward, the executor is personally liable if they did not take reasonable steps to identify creditors. The Trustee Act 1925 s.27 protects executors who advertise for creditors — anyone not responding to the advertisement cannot then claim against the executor personally; (4) Delay (devastavit by mismanagement): an executor who unreasonably delays administration — allowing IHT interest to accrue, or failing to preserve estate assets — can be personally liable for losses caused by the delay; (5) Incorrect valuations: an IHT valuation that is demonstrably too low can result in HMRC challenging the figure and imposing interest and penalties. The executor should obtain professional valuations for property and other significant assets; (6) Protection mechanisms: a well-informed executor can protect themselves by: obtaining professional valuations; advertising for creditors under TA 1925 s.27; not distributing early; keeping proper records and accounts; seeking legal advice for complex estates.
