Texas Biographical Affidavit Update is an affidavit form used to update biographical information for individuals who have previously submitted a Texas Biographical Affidavit. Individuals can use this form to update their name, address, date of birth, Social Security number, and other information. This form is commonly used by individuals who have changed their name or moved since they last completed a Texas Biographical Affidavit. There are two types of Texas Biographical Affidavit Updates: the Individual Update and the Family Update. The Individual Update is used to update the biographical information of a single individual, while the Family Update is used to update the biographical information of a family. Both forms must be notarized and signed by the individual or individuals listed on the form.
