Advise the testator if you are under 18, as this disqualifies you from witnessing a will. Ask if you are a beneficiary under the will, as in most cases beneficiaries should also not witness a will signing, advises the Washington State Bar Association.
Check to determine that there are at least two witnesses in the room in addition to the testator, or at least three witnesses in the state of Vermont, advises FindLaw.
Sit where you can physically observe the testator sign the will. Remain in the room while all necessary witnesses sign the will.
Sign the will where indicated by a witness signature line. Use a non-erasable ball point pen, or a fountain pen and ink,. You may also inscribe a date adjacent to your signature or on a separate designated date line. If requested, print your name in addition to your signature.
