I have sole custody of my two children and their father hasn't been around for years he pops in and out(through the phone) every two years and my husband wants to adopt them does anyone know what I can do? He pays child support for 2 months then stops for a year or so then another two months but he won't sign over his rights. What can I leagely do to make him? He is a acholic and drug user and he hasn't ask to visit them either. Visitation is court order as I see fit. Any help is sooo apprecitated.
