G.F.
Sounds crazy and I'm sorry you have to go through this. If you want the child support from him, you can go to the Child Support Enforcement office..and they'll make sure he pays without the sexual favors. But, it sounds to me that you just want him to give up parental rights so that your husband can legally adopt him? If I am correct, you will need to go to court. Your best bet would be to hire a lawyer for this. good luck
