Will Witnesses UK: Who Can Sign & Legal Rules
We're not a law firm — we help you find the right legal support. For advice on your situation, speak to a legal adviser or find a solicitor.
Putting a will in place is one of the most important steps you can take for the people you care about, yet the part that trips most people up is not the wording itself, it is the signing. Under the law of England and Wales, a will only becomes legally effective once it has been signed and witnessed in a very particular way.
Get the witnessing wrong and even the most carefully drafted will can fall apart, leaving your estate to be distributed under the intestacy rules rather than your own wishes. This guide walks through who can act as a witness, who really should not, what the witnesses are actually doing on the day, and the common mistakes that make wills vulnerable to challenge. The aim is to give you a clear picture of how to get this final step right.
What this document is
A witness to a will is someone who observes you signing your will (or acknowledging your signature) and then adds their own signature to confirm what they saw. In England and Wales, the core rule comes from the Wills Act 1837, which requires two witnesses to be present together when the will is signed, and for each of them to sign in your presence.
Their job is not to read your will, check its contents, or verify what it says. They are there to confirm, if ever asked, that you signed it freely, that you appeared to know what you were doing, and that the formalities were followed on that date.
Because of this, witnesses play a quiet but powerful role. If someone later challenges the will, for example on the basis that you lacked mental capacity or were pressured into signing, the witnesses may be asked what they observed. Choosing the right people, and carrying out the signing properly, is what gives a will its legal backbone.
How to use this document
- Pick two adults who will not benefit. Choose two people aged 18 or over who have no personal stake in the will. That means not your spouse or civil partner, not anyone named as a beneficiary, and not the spouse or civil partner of a beneficiary. A gift to a witness or their partner can be forfeited even though the will itself remains valid.
- Check they have the capacity to witness. Your witnesses should be of sound mind, able to see you sign, and able to understand what they are being asked to do. Someone who cannot see, who is heavily intoxicated, or who lacks mental capacity on the day is not a safe choice. Neutral adults such as neighbours, colleagues or friends from outside the family usually work well.
- Gather everyone in the same place at the same time. The law requires both witnesses to be present together when you sign, or when you acknowledge a signature you have already made. You do not need a solicitor's office, your kitchen table is fine, but the three of you must be in the same room, able to see each other, for the whole signing process.
- Sign the will in their presence. Sign and date the will yourself while both witnesses watch. Use the same pen throughout if possible, and sign in the place the will indicates, usually at the end of the document and sometimes on every page. Do not leave any blanks unfilled before signing, as unexplained gaps can raise questions later.
- Have both witnesses sign and record their details. Each witness then signs the will in your presence, ideally directly after you, and prints their full name, address and often their occupation next to their signature. Keep the original will somewhere safe and tell your executors where it is. A will that cannot be found is almost as unhelpful as one that was never made.
Common questions
Q Can a family member witness my will?
A family member can witness your will as long as they are not a beneficiary and are not married to or in a civil partnership with a beneficiary. So an adult child who inherits nothing under the will could technically witness it, but it is usually safer to choose someone entirely outside the family. That way there is no argument later about influence or bias, and no risk of a gift being lost due to a witnessing mistake.
Q What happens if a beneficiary accidentally witnesses the will?
Under section 15 of the Wills Act 1837, any gift to a witness or to their spouse or civil partner is generally void. The will itself usually remains valid, and everything else in it takes effect, but that particular beneficiary loses what they would have received. This is one of the most common and costly mistakes, and it is why beneficiaries and their partners should never be asked to witness.
Q Do witnesses need to read the will before signing?
No. Witnesses are not there to check the contents or approve what the will says. They are confirming that they saw you sign it, that you appeared to do so freely, and that you seemed to understand what you were signing. Many people prefer to keep the contents private, and witnesses can sign without seeing anything other than the page with the signatures on it.
Q Can a will be witnessed over video call in the UK?
Temporary rules introduced during the COVID-19 pandemic allowed video witnessing of wills in England and Wales for a limited period, but those arrangements have now ended. The safest course today is to treat in-person witnessing as the standard requirement. If your circumstances make that difficult, speak to someone experienced before relying on any remote arrangement, as getting this wrong can invalidate the whole will.
Q What if one of my witnesses dies before me?
A witness dying does not affect the validity of your will. Once the will has been properly signed and witnessed, it stays valid regardless of what happens to the witnesses afterwards. Their details may still be useful to your executors during probate if any questions arise, which is why it is helpful to record full names and addresses at the time of signing.
Q Does a solicitor have to be one of the witnesses?
No. There is no rule that a solicitor or any other professional must witness your will. Two independent adults with capacity are all the law requires. That said, people sometimes prefer to have a professional involved because it reduces the chance of procedural mistakes and can make it easier to defend the will if it is ever challenged on capacity or undue influence grounds.
Q Can my executor be a witness?
Yes, an executor can witness your will provided they are not also a beneficiary under it. Being named as executor alone is not a gift, so it does not trigger the forfeiture rule in section 15 of the Wills Act 1837. However, if your executor is also inheriting something, asking them to witness would cause them to lose their inheritance, so it is better to pick someone else.
