Self-Proving Affidavit
You should include a notarized self-proving affidavit to the will. This is a separate sheet of paper attached to your will that is signed and sworn to under oath)at the same time you sign your will before witnesses.
If a will is accompanied by a self-proving affidavit, it may be admitted to probate without delay or further contacting the witnesses.
Without a self-proved affidavit, your will cannot be admitted to probate until the court determines that it is valid. This can mean the witnesses must be located and asked to sign an oath, or if the witnesses are dead, someone may have to verify your handwriting.
