I just recently got married and my husband is wanting to adopt my two children from my previous marriage. My ex-husband still has rights to the kids but we are wondering how difficult it would be to have his rights terminated. He has not seen the children in 10 months, has had absolutely no contact with them for that entire time. He also is not paying for the things he was court ordered to pay. He just recently began paying child support after not paying for 7 months and is behind over $3000. I have talked to him about signing over his rights and he refuses. How difficult would this be to do?
