Will Witnessing Requirements: What Every State Needs in 2026

Improper witnessing is the #1 reason wills fail in probate. Getting it right takes about 15 minutes.

Universal rules - Two adult witnesses in nearly every state - Witnesses must be disinterested — not beneficiaries - Witnesses must be present at the same time the testator signs - Witnesses must sign in the testator's presence

Self-proving affidavit A sworn statement signed by the testator and witnesses in front of a notary at the time of signing. Lets the court accept the will without tracking down witnesses years later. Strongly recommended.

Common mistakes that void a will - Beneficiary served as witness - Witnesses signed at different times or locations - Notary signed but no witnesses present - Electronic signatures used in a state that does not allow them

What to do Print, gather two adult disinterested witnesses, drive to a notary, sign all three signatures in front of the notary in one sitting. Store the original where your executor can find it.
