Who can witness a will? Guide for England and Wales

When you make a will, choosing the right witnesses is a small step that protects the whole document. The law in England and Wales is straightforward, but there are some traps that can unintentionally affect gifts or lead to challenges. This guide explains who can witness a will, who should not witness, and practical tips to make sure your will is legally valid.

Who can legally witness a will?

Under the rules that govern wills in England and Wales, any person aged 18 or over, of sound mind, can act as a witness. The key legal requirements are that the witness must be physically present when you sign the will, they must understand that they are witnessing a will, and they must then sign the document in your presence.

These formalities come from long established law, including provisions found in the Wills Act 1837, so following them closely helps ensure your wishes are respected.

Why you need two witnesses

The law requires two independent witnesses. Both must see you sign the will, or see you acknowledge your signature, and then both must add their own signatures while in your presence. If a witness signs after you leave, or signs without being present, that section may be invalid and could put the will at risk.

Who should not witness your will?

There are some people you should avoid asking to act as witnesses:

• Named beneficiaries in the will, and their spouses or civil partners, should not witness. If a beneficiary acts as a witness, they may lose the gift left to them by the will. The rest of your will can still be valid, but the gift to that witness will usually be void under the rules that prevent witnesses gaining from the documents they witness.
• Anyone with an interest in the estate, including people you expect might benefit under intestacy rules, should be avoided where possible.
• People who may not understand what they are signing, for example if they are not of sound mind or are significantly impaired at the time of signing.

Practical tips when choosing witnesses

• Choose independent adults, such as trusted friends, neighbours, or professionals who are not named in the will.
• If you use a solicitor or will-writing service, they can often provide suitable witnesses, but practical checks are still important.
• Make sure witnesses bring ID if you want extra certainty about who they are. Record their names, addresses and occupations on the attestation clause of the will.
• If you expect a dispute, consider discussing your will with beneficiaries in advance, or take professional advice to reduce later challenges.

Signing when you cannot sign

If you are physically unable to sign, someone else can sign on your behalf, but only if you direct them to do so in your presence, and the two witnesses must be present for that act. This is less common, and professional legal help is advised to make sure the formalities are correctly observed.

If a beneficiary has witnessed your will by mistake

If a beneficiary or their spouse has witnessed your will, that person may lose the gift intended for them, but the rest of the will will normally remain valid. To avoid this risk, consider re-executing the will with appropriate independent witnesses. If you are unsure, seek advice promptly to correct the situation.
