If the change involves adding a father's information to a birth certificate on which the father's information was left blank, the supporting documentation needed is either the certified copy of a marriage license or an Acknowledgement of Paternity. However, if paternity was established by a court order, you must submit a certified copy of that court order. A court order will also be required if changes have previously been made to the birth certificate.
If the change you are wanting to make involves removing the father's information or removing one man's information and adding the information of another man, the supporting documentation must be a certified copy of a court order saying that the man listed on the birth certificate is not the biological father or that the man to be added to the birth certificate is the biological father. In some cases, a properly filled out and signed, first-time-ever Acknowledgement of Paternity can be submitted if ths "denial" portion has been filled out.
Texas Vital Statistics will create a new supplemental record based on paternity, remove the original from the records, and file the supplemental record. A copy of the supplemental record will also be forwarded to the local registrar and will replace the original record in the local registrar's files. The Application for New Birth Certificate Based on Parentage, supporting documents, and the original birth certificate will be placed in a sealed paternity file upon acceptance for filing. This sealed file can be opened only by a district court or a court with family-law jurisdiction.
Since 1966, most paternity actions through Texas courts have been reported to Texas Vital Statistics. If a court has provided sufficient information to validate an adjudicated action, a certified copy of the court decree is not required.
When an application for a new birth certificate based on parentage is submitted along with a certified copy of a marriage license or an Acknowledgment of Paternity, the parents can, in most cases, change the child's name without needing a court-ordered change of name. If the application for a new birth certificate based on parentage is supported with an adjudicated action, the court order must specify the new name of the child in order for the new name to be incorporated into the supplemental certificate.
A specialist trained in parentage issues will review your application. However, we cannot file the new application until all aspects of your application have been reviewed. If filing is not possible, Texas Vital Statistics will send you a letter explaining the situation.
