It is not a requirement to change your name in Texas, but you must notify the Secretary of State’s office of an address change. Name Change If you choose to change your name, you need to submit the name change application form (which you can obtain from a bonding agency), your certificate of commission, a rider or a new bond with your new name from your bonding agency, and the filing fee ($20). Once you have submitted the request to change your name you cannot continue using your old commission information. You must wait until you have a new commission certificate and a new seal before continuing your notary duties. You do not have to update your commission information with a name change, though. For instance, if you get married and change your last name, you do not need to update your commission information; you can continue using your old stamp, but then you must continue signing with the name on your stamp. Address Change The Secretary of State needs to be informed of the change of address within ten days.  You may either fill out a Notary Public Change of Address or you can submit a letter to the Secretary of State. The letter needs to include your name, your social security number, your old address and your new address. Send the letter to: Secretary of State Notary Public Unit P.O. Box 13375 Austin, Texas 78711-3375 All of this information can be found on the Secretary of State’s website or call one of our Customer Care Representatives at 800.821.0822.
