Legal Question in Family Law in Texas

So you signed the birth certificate and a court has established the parent child relationship between you and the child? Unless the court did this within the last 30 days, I think you may be responsible from here forward. There maybe other factors that I do not know about. But it sounds like to me you are the legal father. I suppose you could find the real biological father and get an agreement with him to go to court and get all this resolved. Depnds a lot on the mother's cooperation as well.
