Your will can’t be witnessed by anyone who stands to benefit from it. This includes:
Anyone you’ve left a gift or part of your estate to – otherwise known as beneficiaries. This means that, if you’ve chosen to leave your estate to your partner and children, they can’t witness your will.
The spouse or civil partner of any beneficiaries. So, if you’ve chosen to leave part of your estate to your daughter, your daughter’s husband can’t witness your will.
It’s also important to note that your will can’t be witnessed and signed by someone who is blind, as they need to be able to see you sign your will.
