Understanding will validity requirements UK

For a will to be valid in England and Wales, it generally has to meet the formalities in section 9 of the Wills Act 1837: it is in writing, signed by the testator (or by someone in their presence and at their direction), and that signature is made or acknowledged in the presence of two witnesses present at the same time, who then each sign in the testator's presence. Alongside the formalities, the law also asks about testamentary capacity, knowledge and approval of the contents, and the absence of undue influence.

Common document themes include how and where the will was signed, who the witnesses were, whether a witness or their spouse benefits under the will, whether the testator understood the document, and whether it was properly dated and stored. VetroCheck publishes this page as general legal information only. No solicitor-client relationship is created by using this service. There is no paid document upload for this topic.

Where fees are mentioned (for example probate application fees later in the process) they are policy amounts that change — as of July 2026 confirm any figure on the live GOV.UK page linked under Official resources rather than an older source. This guide explains the general requirements and the issues that commonly lead people to question a will. It does not assess any individual will, estate, or family situation, and it makes no prediction about how a court would decide.

The section 9 formalities

Section 9 of the Wills Act 1837 requires a will to be in writing and signed by the testator (or by another person in their presence and at their direction), with the signature made or acknowledged before two witnesses present at the same time, each of whom then signs in the testator's presence. A failure in any of these steps can put validity in question. The formalities are strict, which is why signing procedure matters so much.

Testamentary capacity

The long-standing test from Banks v Goodfellow asks, in broad terms, whether the testator understood the nature of making a will and its effect, the extent of their property, and the claims of those they might be expected to provide for, without a disorder of the mind affecting their decisions. Capacity is assessed at the relevant time. Doubts about capacity are a frequent basis on which wills are questioned.

Knowledge and approval

A valid will requires that the testator knew and approved its contents at the time of execution. This is usually presumed where a capable testator signs a properly executed will, but the presumption can be displaced where there are suspicious circumstances, such as a will prepared by a major beneficiary. Evidence of how the will was explained and read can be relevant to this question.

Undue influence and fraud

A will can be challenged if it was made because of undue influence amounting to coercion, or through fraud. The bar for proving undue influence in the context of wills is high, and mere persuasion is not enough. Allegations of this kind are fact-heavy and depend on the surrounding circumstances and evidence. This is an area where specialist advice is common.

Witnesses and the beneficiary rule

The two witnesses must be present together when the testator signs or acknowledges the signature. A significant pitfall is that if a witness, or the spouse or civil partner of a witness, is a beneficiary, the gift to that person is generally void, even though the will itself can remain valid. Choosing independent witnesses avoids losing a gift for this reason.

Revocation and later wills

A will can be revoked by a later will or codicil, by a formal act such as destruction with the intention of revoking, and in some circumstances by marriage or the formation of a civil partnership. A later valid will usually revokes earlier inconsistent provisions, and a clear revocation clause helps. Divorce or dissolution can affect gifts to a former spouse. The current law governs how these rules apply.

Common practical pitfalls

Recurring problems include witnessing done remotely or not simultaneously, a beneficiary acting as a witness, unclear amendments or crossings-out on the face of the will, missing dates, and uncertainty about which document is the last will. Storage matters too: an original that cannot be found raises a presumption issue. Careful execution and safe storage prevent many disputes later.

What happens if a will is invalid or missing

If there is no valid will, the estate passes under the intestacy rules, which set a fixed order of who inherits and may not match what the deceased would have wanted. A partial failure, such as a void gift to a witness-beneficiary, is dealt with according to the will's terms and the law. Establishing which document is the valid last will is often the first question in an estate.

FAQ

Frequently asked questions

  • In general terms a will must meet the section 9 Wills Act 1837 formalities: in writing, signed by the testator (or at their direction), with the signature made or acknowledged before two witnesses present together who each then sign. Alongside this, the testator must have had capacity, known and approved the contents, and not acted under undue influence. Whether these general points apply to a particular will depends on the specific facts, the document, and the up-to-date law — a qualified solicitor or the relevant probate registry can address an individual situation, and this guide is information only and does not assess any individual will.

  • Yes. For a standard will the signature must be made or acknowledged in the presence of two witnesses who are present at the same time and who then each sign in the testator's presence. Getting the witnessing wrong, such as witnesses not being present together, is a common reason validity is later questioned. There are limited exceptions for privileged wills, which are narrow. Whether these general points apply to a particular will depends on the specific facts, the document, and the up-to-date law — a qualified solicitor or the relevant probate registry can address an individual situation, and this guide is information only and makes no prediction about any outcome.

  • A beneficiary, or the spouse or civil partner of a beneficiary, can technically witness a will, but doing so generally makes the gift to that person void, even though the will as a whole can remain valid. Using two independent witnesses who take no benefit avoids losing a gift in this way. It is a frequent and avoidable pitfall. Whether these general points apply to a particular will depends on the specific facts, the document, and the up-to-date law — a qualified solicitor or the relevant probate registry can address an individual situation, and this guide is information only rather than advice on any one document.

  • Testamentary capacity, under the test from Banks v Goodfellow, broadly means the testator understood that they were making a will and its effect, the extent of their property, and the claims of those they might be expected to provide for, without a disorder of the mind affecting their decisions. It is assessed at the relevant time. Capacity concerns are a common basis for questioning a will. Whether these general points apply to a particular will depends on the specific facts, the document, and the up-to-date law — a qualified solicitor or the relevant probate registry can address an individual situation, and this guide is information only and makes no assessment of any person's capacity.

  • A will can be questioned on grounds such as a failure of the formalities, lack of capacity, lack of knowledge and approval, undue influence, or fraud, and separately a claim for reasonable financial provision can be made under the relevant 1975 Act. These are distinct routes with different tests and time limits. Whether any of them fits a particular estate depends heavily on the facts. Whether these general points apply to a particular will depends on the specific facts, the document, and the up-to-date law — a qualified solicitor or the relevant probate registry can address an individual situation, and this guide is information only and does not predict any result.

  • If there is no valid will, the estate is distributed under the intestacy rules, which set a fixed order of inheritance that may not reflect what the deceased would have chosen. A void gift within an otherwise valid will is handled according to the will and the law. Establishing which document is the valid last will is often the first step in administering an estate. Whether these general points apply to a particular estate depends on the specific facts, the documents, and the up-to-date law — a qualified solicitor or the relevant probate registry can address an individual situation, and this guide is information only.

  • Alterations made after a will has been signed are generally not effective unless they are executed with the same formalities, so handwritten changes or crossings-out can create uncertainty rather than a valid amendment. A separate codicil, properly executed, is the usual way to make a change, and a new will is common for larger changes. Whether these general points apply to a particular will depends on the specific facts, the document, and the up-to-date law — a qualified solicitor or the relevant probate registry can address an individual situation, and this guide is information only and does not assess any particular alteration.

  • In many circumstances marriage or the formation of a civil partnership revokes an earlier will unless the will was made in contemplation of that marriage, while divorce or dissolution can affect gifts to and appointments of a former spouse. Because these rules can change the effect of an existing will significantly, reviewing a will after a major life event is common. Whether these general points apply to a particular will depends on the specific facts, the document, and the up-to-date law — a qualified solicitor or the relevant probate registry can address an individual situation, and this guide is information only.

  • The original signed will should be stored safely and its location recorded, because if the original cannot be found after death, the law may presume it was destroyed with the intention of revoking it, which can complicate the estate. Options include storage with a solicitor, a will-storage service, or the probate service where available. Whether these general points apply to a particular situation depends on the specific facts and the up-to-date law — a qualified solicitor or the relevant probate registry can address an individual situation, and this guide is information only rather than advice on any one estate.

  • This is an information guide explaining the section 9 formalities, capacity, knowledge and approval, undue influence, and the common pitfalls that lead people to question a will. There is no paid upload for this topic, and any fee mentioned is treated as changeable. Related guides cover probate, codicils, trusts, and inheritance provision claims. Whether these general points apply to a particular will depends on the specific facts, the document, and the up-to-date law — a qualified solicitor or the relevant probate registry can address an individual situation, and this guide is information only and makes no prediction about how any dispute would be decided.
