In Texas, you don't need to notarize your will to make it valid. A notary is required if you want to make your will self-proving. When a will is self-proving , the court can accept your will without needing to contact your witnesses to prove its validity. This can speed up the probate process. To make your will self-proving, you must include a self-proving affidavit. In it, you and your witnesses state that your will was signed by you in the witnesses' presence, and that you've declared it to be your will. Your self-proving affidavit must be signed ( or acknowledged) by both you and your witnesses in front of a notary, who will then notarize the affidavit.
