Washington self-proving affidavit forms are sworn statements that may be attached to a last will and testament in order to make it a self-proving will. The purpose of the affidavit is to provide the sworn testimony of any or all witnesses who signed the testator’s will. This certificate will be admissible in court if their testimony is required. By making their will self-proving, the testator shortens the probate process and adds further validation to their final instructions. State law doesn’t require all of the witnesses to sign the affidavit, however, any witnesses who do not sign a self-proving affidavit will have to present themselves in court if they are called to give their testimony.
