Create a high quality document online now!

Updated January 10, 2023

An Oklahoma self-proving affidavit form is a notarized document that can be attached to a last will and testament in order to validate it. A self-proving will bypasses the probate process whereby the will’s witnesses may be called to attest the will in person. This affidavit contains the sworn statement of the principal signatory (the testator) and two (2) witnesses affirming that the will was executed willingly and in full capacity by the testator. By having this affidavit attached to the will, the witnesses will not need to testify in person in probate court when the estate is divested, thus quickening the probate process.


  • Statute§ 84-55(5)
  • Signing Requirements – Two (2) witnesses and a notary public.
