- a parent served by citation by publication;
- an alleged father who failed to register with the registry under Texas Family Code chapter 160 and whose identity or location is unknown; and
- an alleged father who registered with the paternity registry under Texas Family Code Chapter 160, but the petitioner's attempt to personally serve citation at the address provided to the registry and at any other address for the alleged father known by the petitioner has been unsuccessful.
