Can a family member witness a will?

A family member can witness your will only if they are not a beneficiary or married to a beneficiary. If a beneficiary or their spouse/civil partner witnesses the will, they will lose their inheritance, although the will itself remains valid. For this reason, it’s safest to choose independent witnesses who are not related to you by blood, marriage, or partnership. Witnesses must also be over 18 and mentally capable. Using independent witnesses ensures there are no conflicts of interest and your will remains legally sound.
