My wife had a baby out of wedlock in the state of texas and has been raising the child by herself for 5 years now. The biological father of the child is in the military and obligated to pay child support. He does not see the child, visit, communicate or anything by his own doing. i married my wife 3 years ago and have been the only father figure that she knows. We have tried to make contact with the father to give him updates about her our address phone number etc but he doesn't respond or he would have "agents" send misc emails saying he doesn't want anything to do with the child. We have relocated to a overseas location and the child needs to have her passport updated in order to leave the country but we cannot find/locate/contact the biological father. Is there any way that i can legally adopt my stepdaughter without his consent, stop him from paying child support and have full custody/support of my child. Can anyone that has been in a similar situation or has advice comment. thanks
