Acknowledgement of Paternity (AOP)
  • The AOP process establishes legal paternity for a child born to unmarried parents.
  • The AOP is a legal document under Texas Law and has the same effect as a court order establishing paternity.
  • The AOP is a critical process in ensuring the child is eligible for benefits such as Social Security, Veteran assets, child support and health care.

  • The fee to file a new birth certificate based on paternity is $25.00.
  • The additional fee for a certified copy of the updated birth record is $22.00.
  • Fees are paid directly to the State Vital Statistics Office at Austin, Texas.

For your convenience, a list of locations that provide walk-in AOP services without an appointment is here.
