Updated June 01, 2022

A Michigan self-proving affidavit form is a document that can be attached to a last will and testament to validate the will after the testator’s death. The testator (person who created the will) can choose to use a self-proving affidavit, by signing in the presence of two (2) witnesses and a notary public, so that the witnesses needn’t appear before the court to advocate the legitimacy of the will. Similar to an attestation clause, a self-proving affidavit affirms that the will was created voluntarily and while the testator was of sound mind. While it is not a mandatory attachment to a will, the affidavit can significantly speed up the process so that the testator’s beneficiaries can claim their expected portion(s) of the estate.
