Do I need to have my WillMaker will notarized?
No. You must sign your will in front of two witnesses, but no state requires that a will be notarized to be valid.
That said, some states allow you to attach a self-proving affidavit, which must be notarized, to your will. A self-proving affidavit is a separate document, signed by your witnesses, that makes it simpler to admit your will to probate after your death. If your state offers this option, your WillMaker will will print out with a self-proving affidavit.
