What does a witness to a will do?

Signing a will is never just a formality. In the UK, particularly in England and Wales, witnessing a will plays a vital role in ensuring the document reflects the true, voluntary intentions of the person making it (the testator). Strict will witness requirements exist to avoid conflicts of interest and reduce the risk of disputes after death.

A witness for will signing confirms that the testator signed the will willingly, while in sound mind. Although the task may appear straightforward, choosing who can witness a will must follow precise legal criteria. Even a minor error, such as selecting a beneficiary or someone too closely connected, can invalidate part of the will or call its validity into question.

What are the legal requirements to be a witness to a will?

Under UK law, to satisfy the will witness requirements, a valid witness for will signing must meet:

• Be at least 18 years old;
• Be physically present at the time the will is signed;
• See the testator sign the will, or acknowledge their signature in in the witness’s presence;
• Not be a beneficiary, nor married to or in a civil partnership with a beneficiary (which answers the common question: can a beneficiary witness a will? The answer is no).

These strict criteria exist to ensure impartiality and to protect the testator from any appearance of undue influence.

Can a beneficiary witness a will?

This is one of the most common, and serious, mistakes in will writing. While it may seem convenient to ask a close friend or relative to serve as a witness for will signing, UK law is clear: can a beneficiary witness a will? No. Under the Wills Act 1837, if a beneficiary, or their spouse or civil partner, acts as a witness, the gift made to them becomes void. The will itself remains legally valid, but the beneficiary in question loses their entitlement.

These avoidable often lead to family disputes or even litigation. To protect your final wishes, it is essential to choose independent witnesses with no connection to any named beneficiary.

For peace of mind, always seek help from a solicitor specialising in wills, trusts and estate law, who can guide you through the drafting process and ensure your will complies with all legal requirements.

Can a family member be a witness to a will?

Legally, the answer to can a family member be a witness to a will is yes—provided they are not a beneficiary and not married to or in a civil partnership with one.
However, doing so can raise doubts or lead to disputes if the will is later challenged. Even when technically valid, having a relative as a witness for will signing may create the perception of bias or undue influence.

For this reason, most solicitors specialising in will writing recommend choosing independent witnesses with no family or financial connection to the estate.

Can a solicitor witness a will?

A solicitor can witness a will, provided they are not a beneficiary and are not named as executor. In many will writing or law firms settings, solicitors frequently serve as independent witnesses to help ensure the will’s validity and prevent future disputes.

Can an executor witness a will?

An executor can act as a witness, but with a key condition:  they must not also be a beneficiary. While this is legally permitted, it can cause practical complications, as executors are often close family members who also inherit under the will. If in doubt, choose separate individuals for these roles.

Good to know: To avoid any conflict, appoint an executor who is not a beneficiary, and choose neutral witnesses. A solicitor specialising in wills, trusts and estate law can help you structure this correctly.

Can a married couple witness a will in the UK?

Can a husband and wife witness a will? Yes, as long as neither person is a beneficiary. If even one of them is named in the will, the gift to that person becomes void. For full legal protection, it’s best to choose witnesses who are completely independent of the estate.

Can a non-UK national witness my will?

A foreign national can act as a witness, as long as they meet the legal criteria.  A non-UK national can witness your will as long as they over 18, physically present during the signing, and are not a beneficiary of the will.

However, there may be practical complications, especially if the witness resides abroad and must later be contacted during a legal challenge. While legally valid, choosing a witness who is easily reachable is often more prudent.

Can a relative witness a will, specifically a parent?

Yes—if they are not a beneficiary under the will. That said, involving a parent as a witness for will signing can raise red flags in contentious situations, especially where undue influence might be alleged.  For this reason, legal experts in wills, trusts and estate law usually advise appointing truly independent witnesses to avoid disputes.

What are the powers of an executor in the UK?

Quite a lot. An executor is the person named in the will to carry out the testator’s instructions, manage their estate, and ensure legal and financial matters are properly settled. This role is governed by UK law and carries serious responsibilities.

Key duties include:

• Gathering the deceased’s assets (bank accounts, property, life insurance, valuables, etc.);
• Paying outstanding debts, bills, and funeral expenses;
• Managing tax obligations, including final income tax returns and Inheritance Tax;
• Distributing the estate according to the terms of the will.

This is a position of trust that demands diligence, transparency, and impartiality. Poor handling of these duties can lead to estate delays, family conflict, or legal action.

To ensure your estate is managed properly, a solicitor specialising in wills, trusts and estate law can help you choose a suitable executor, or act as one professionally. This is often the best solution for complex estates or where disputes may arise.

FAQs

• What happens if a witness to a will dies UK? If the witness dies after signing the will, the will remains valid. However, it may be harder to prove its validity if the will is contested later, so keeping clear records is advisable.
• Can anyone witness a will? While many adults can witness a will, they must be over 18, not a beneficiary, and not married to or in a civil partnership with a beneficiary.
• Can a stranger be a witness to my will? A stranger, someone with no interest in the will, is often the best choice, as they are independent and less likely to raise concerns of bias or conflict of interest.
