The address to mail all child support payments:

TEXAS CHILD SUPPORT DISBURSEMENT UNIT
P.O. BOX 659791
SAN ANTONIO, TX 78265-9791

You will need to include the following identifiers on the check: obligor’s name, TxCSDU case number and the county cause number. This will ensure that the child support payment is posted to the correct case. If payments are posted to an incorrect case due to missing identifiers, the TxCSDU may be unable to make the proper adjustments to retrieve the monies for the correct case. Therefore, it is imperative that the correct information is included on the face of each payment.

For additional options, please see more Child Support Payment Options.
