This document outlines five things that are required for a successful probate application: 1) the original last will and testament, 2) an affidavit of execution sworn by a witness, 3) complete details of the estate's assets and their values, 4) proof of the death, such as an original death certificate, and 5) probate fees or estate administration taxes that need to be filed with the application.
