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. This affidavit is as good as in-court testimony and will make it difficult for a beneficiary or other individual to challenge its authenticity.
