Updated January 09, 2023

An Idaho self-proving affidavit is a legal form that can be incorporated into, or attached to, a last will and testament to help prove the validity of the will. The affidavit assures the probate court that the testator (the individual who created the will) made the will voluntarily and was competent at the time of its execution. A self-proven will makes it unnecessary for the testator’s witnesses to visit the probate court to affirm the truthfulness of the will following the testator’s death. When executing the document, the testator must provide their signature in the presence of two (2) witnesses and a notary public.


  • Statute§ 15-2-504
  • Signing Requirements – Two (2) witnesses and a notary public.
