Self-proving affidavitA will can be made self-proved when the will-maker and witnesses sign before a notary public, justice of the peace, or other official authorized to give oaths, who completes the acknowledgment and affidavit wording set out in the statute. A will meeting the Uniform International Wills Act (RSA 551-A) also counts as self-proved.
