If you have consent of the father of record, then it's straightforward. You both fill out the order, etc... (http://texaslawhelp.org/resource/chi...ions-english-s), notarize and file it. You'll get a court hearing. The TFC still requires the judge to determine it's in the best interest of the child.
If the father doesn't agree (or isn't known), you've got additional steps of actually serving or publishing.
