Co-Executor UK (2026): Appointing Multiple Executors in Your Will

Yes. You can name up to four executors in a will in England and Wales (the maximum number who can take out a grant of probate at the same time under rule 27 of the Non-Contentious Probate Rules 1987). There is no minimum — a sole executor is perfectly valid — but naming two is very common as it provides a backstop if the first executor dies or is unable to act. Named executors who are not needed immediately can have 'power reserved' to them, allowing them to step in later without having been party to the original grant.

Unlike trustees, who can be appointed 'jointly and severally' (enabling each to act independently), executors in England and Wales are always appointed jointly. This means that for significant estate decisions and legal acts — selling a property, signing documents, distributing assets — all proving executors must act together and agree. One co-executor cannot unilaterally sell an estate asset or distribute funds over the head of the other(s). For routine administrative acts (collecting post, cancelling direct debits, dealing with HMRC correspondence), a single executor can generally act without the others, but for any disposition of estate assets, unanimity is required. This joint requirement is the primary reason disputes between co-executors are so problematic — there is no straightforward way for one to override the other.

Power reserved is a mechanism under rule 27(6) of the Non-Contentious Probate Rules 1987 that allows a named executor not to prove the will alongside the other executors at the time of the original grant of probate, while preserving their right to apply for a grant later (known as a 'double probate'). An executor with power reserved is not renouncing — they are simply standing aside temporarily. This is useful where: one executor is abroad and the delay in obtaining their participation would be costly; one executor is elderly or unwell; or the testator has named a young child as executor (who would need to wait until they turn 18). Power reserved should be recorded formally by a notice served on the proving executors and confirmed in the statement of truth accompanying the probate application.

If co-executors cannot agree on a matter affecting estate administration, the options are limited and potentially expensive. The most common resolution mechanisms are: (1) Mediation — executors agree to use a neutral third party to facilitate agreement, avoiding court costs. (2) Court application — either executor can apply to the Chancery Division of the High Court for directions on a specific matter (for example, whether a particular property should be sold or retained). The court will consider the interests of the beneficiaries, not just the executors' personal preferences. (3) Removal — any executor who is obstructing the administration can be removed by the court under section 50 of the Administration of Justice Act 1985, and a substitute administrator appointed. Removal is a last resort and requires evidence of serious misconduct or deadlock; it will not be granted simply because co-executors disagree on timing. The costs of any court proceedings are typically borne by the estate, which ultimately reduces the beneficiaries' inheritance.

Yes. An executor who does not wish to act at all — rather than standing aside temporarily — can renounce their right to prove the will, provided they have not already intermeddled in the estate (taken any actions that constitute acting as executor). Renunciation is formal and irrevocable once filed: it is effected by signing a form of renunciation and filing it with the Probate Registry. An executor who renounces completely ceases to have any role in the estate administration. By contrast, power reserved is temporary — the executor retains the right to come back in later. If a co-executor has already started dealing with estate matters (collecting assets, paying debts, communicating with banks), they may have intermeddled and could be treated as having accepted the role even without proving the will, which can make renunciation impossible.

The most common approach for a straightforward estate is to appoint two executors: a primary executor (often a spouse or adult child) and a substitute in case the first is unable or unwilling to act. Naming three is also reasonable — it provides two levels of backup and can be useful for complex or valuable estates where multiple perspectives on decision-making are beneficial. Naming four (the maximum who can prove together) is less common and can increase the risk of disagreement. Some practitioners suggest that for a will creating a trust, it is useful for the executors and the trustees to overlap — trustees require at least two individuals or a trust corporation, and having the same people in both roles simplifies the estate-to-trust transfer.

Yes — a beneficiary can be (and often is) named as executor. There is no conflict of interest rule that prevents this in England and Wales. In practice, naming an adult child as executor is very common, even if that child is also a major beneficiary. The executor's fiduciary duty to all beneficiaries equally remains unchanged regardless of their own beneficial interest — an executor who is also a beneficiary cannot prefer their own interest over that of the other beneficiaries. Where there is a genuine conflict — for example, an executor who is also a creditor of the estate — they should disclose this to the other beneficiaries and consider whether a co-executor should handle that specific matter to avoid any suggestion of self-dealing.

The surviving executor(s) can continue to administer the estate and are entitled to apply for a fresh grant if needed (under the doctrine that the chain of representation continues). If the deceased co-executor had not yet proved (had power reserved), their right to prove lapses on their death. If the deceased co-executor had already proved and was party to the grant, the surviving executors carry on — the grant remains valid. If all proving executors die before the estate administration is complete, the residuary beneficiaries or their personal representatives may apply for letters of administration de bonis non (of the goods not yet administered) to complete the work. This underlines the importance of naming a substitute executor in the will.
