What are the three eligibility rules for witnesses?
Witnesses must be aged 18 or over, independent of the gifts in the will, and physically present together when you sign. A beneficiary, or their spouse or civil partner, must not witness — the gift fails under section 15 of the Wills Act 1837. Video witnessing ended on 31 January 2022.
- Aged 18 or over. Witnesses must be adults who understand what they are attesting to.
- Independent. A witness must never be a beneficiary of the will, nor the spouse or civil partner of a beneficiary. The will itself remains valid; the gift fails.
- Physically present. Both witnesses must be in the room with you at the same time when you sign or acknowledge your signature — see the exact signing rules.
Who can and cannot witness a will?
Neighbours, colleagues and friends who inherit nothing are ideal. Your spouse almost never can, because they usually inherit. An adult child who inherits must not witness; one who inherits nothing technically can, but independent witnesses are safer. An executor who is not a beneficiary can witness. Nobody aged 17 or under can.
| Person | Can they witness? |
|---|---|
| Neighbour, colleague or friend (not a beneficiary) | Yes — ideal |
| Your spouse or civil partner (a beneficiary) | No — almost always a beneficiary |
| Your adult child who inherits under the will | No — their gift fails (s.15) |
| Your adult child who inherits nothing under the will | Yes, but independent witnesses are safer |
| An executor who is not a beneficiary | Yes |
| A beneficiary's spouse or civil partner | No — the beneficiary's gift fails |
| Someone aged 17 or under | No — witnesses must be 18 or over |
Why does independence matter beyond the legal rule?
Even where a relative technically can witness, independent witnesses carry more weight if the will is challenged decades later. People with no stake in the outcome are easier to trace and harder to accuse of pressure. Neighbours and colleagues are the safer habit — see can a beneficiary witness a will?
When do you need more than a standard witness?
Blind, illiterate or non-English-reading testators need special attestation clauses recording that the will was read over and understood before signing. That is solicitor territory, and our suitability check redirects accordingly. Choose adults who could credibly confirm the ceremony later.
