Do you have contact with your ex? Would he be willing to allow him to adopt them? You could always petition the courts or obtain a lawyer to assist. If it’s uncontested it will definitely be a lot easier and faster. @massgirl, she may be able to answer better for you
@greysonsmommy090316 good luck! If you guys aren't getting along I would suggest having your adoption attorney do it for you. That's what I did lol. My ex and I had nothing to talk about he knew what I wanted and just needed to sign or step up.
