Updated June 01, 2022

A South Dakota self-proving affidavit is a legal form attached to a last will and testament in order to shorten the probate process when the testator’s (the individual who makes a will) estate is distributed among beneficiaries. To be considered legally valid, the affidavit must be signed by the Testator, two (2) witnesses, and a notary public. On the document, the signatories all make a sworn statement swearing that the Testator executed the Will of their own volition without any constraint or undue influence. This document is acceptable as sworn testimony and therefore the witnesses will not need to testify in probate court when the Testator dies and their estate is divided.

  • Signing Requirements – Two (2) witnesses and a notary public.
