Texas Self-Proving Affidavit Form

Updated August 02, 2023

A Texas self-proving affidavit form is a sworn statement used to validate a last will and testament when the will goes to probate. State law requires that two (2) disinterested individuals bear witness to the signing of the will by the testator or another individual who the testator has instructed to sign on their behalf. Normally, when a testator dies, their will goes to probate at which the witnesses may be called to testify that the will is genuine. By attaching a signed and notarized self-proving affidavit to the will, the witnesses will not need to give any further testimony.


  • Statute§ 251-104
  • Signing Requirements – Two (2) witnesses and a notary public.
