When the court order for child support was entered it declared you as the legal father and may include language that says to add you to the birth certificate. If it doesn't you can request an amended birth certificate from the bureau of vital statistics by sending them a copy of the court order and paying a fee. Look up Texas Bureau of vital statistics on the web for directions. Good luck.
Please be advised the posting of this answer does not create an attorney-client relationship. Karen L. Marvel and the Law Office of Arthur G. Augustine, as a condition of their employment, require a signed written employment agreement prior to formally establishing an attorney-client relationship with any person.
You would contact the Bureau of Vital Statistics in Austin, and provide them with certified copy of your order determining paternity. They also have an application form that may be available online to change a birth certificate.
