Missouri Self-Proving Affidavit Form

Create a high quality document online now!

A Missouri self-proving affidavit form is a legal document that allows a last will and testament to move through probate court without the witnesses appearing in court to attest to the validity of the will. For a will to be “self-proved” in the State of Missouri, the testator (individual creating the will) and two (2) witnesses must sign the will in the presence of a notary public. The witnesses, having observed the testator sign the document, will sign the will in turn, corroborating that the testator signed under free will and free from undue influence. The notary public will complete the affidavit form after witnessing all three (3) signatures and attach it to the will. This affidavit is as good as in-court testimony and will make it difficult for a beneficiary or other individual to challenge it’s authenticity.
