Massachusetts Self-Proving Affidavit Form

A Massachusetts self-proving affidavit form is used to validate a testator’s (creator of a will) last will and testament through acknowledging signatures from witnesses in the presence of a notary public. This type of document is advantageous as it simplifies the process a court must go through to check the legitimacy of a will. Furthermore, witnessing parties to a will who have signed a self-proving affidavit will most likely not have to physically appear before the court once the testator dies. In the State of Massachusetts, the law requires two (2) witnesses to sign this document, and a notary public must observe the signatures of the witnesses and the testator. A self-proving affidavit must be attached to the last will and testament once completed.
