I'm not sure what the laws are where you live, but in Iowa, you have to be married at least 12 months or else child services and DHS will have to come to your house and do inspections. My son is now 12 and my hubby and I have been together since he was 5. We were married almost 2 years ago and he adopted my son last August. It was my son's idea. Our lawyer sent my x papers to sign and it took him almost 5 months to do so. But in that time he had gone to a lawyer to have him look over the papers, I guess, and then asked if he would be able to contact my son when he turns 18. He is a BIGGG dead beat dad (well was to my son and I'm sure he still is with his other son). Anyway, our lawyer told us her first move would be to get him to sign the papers and if he wouldn't, she would move forward to have his rights removed. I don't really know all that would have been involved as we didn't get that far, but my lawyer sounded like she had all she needed if it did go that far, but she had also been working with us for the past few years dealing with him, so she knew what kind of person he was and about all that had happened in the past couple of years with him.
I think if you do have to go that route you will need information about him and you'll have to have a reason why he should have his rights removed. Not paying child support is not a good enough reason. Courts won't even take visitation away for that, because the two have nothing to do with each other. You should document every time he calls and if he only talks to you and what he talks about. Why is he calling you every few months if he isn't calling to talk about your daughter?? That seems odd to me. But you should begin documenting everything with him and write down as much about past dealings as you can remember.
As far as talking to him or his family about it. If you are comfortable doing that, then it is up to you to talk to them first or not. In my case, I think if I had he wouldn't have signed. In my humble opinion, only tell them if you don't think they will freak out and get upset with you. You can explain to him and to them that he will still have the option of seeing her and so can they because it is an open adoption, but don't expect them to be happy about it. Have you ever mentioned it to him before or will this be a total shock to him if you do say something to him?? Even though he is a nice guy and such, things may change when he is no longer financially/leagally responsible for her. He won't feel obligated to see her. And if you are going to push on to have his rights removed if he doesn't sign the papers, I wouldn't plan on him being too happy about it.
My x nor his family ever kept in touch with us, so we gave them no warning.
Sorry for the long post. I hope the information I posted is/was helpful to you.
I wish you the best in the process. It is a long process. Ours took about 7 months or so, with most of the time us not knowing anything because our lawyer was waiting to hear from him or his lawyer on if he was signing the papers or not. Waiting is tough, but it was well worth it! It was one of the best things we've done.
Best of luck to you both!! If you have any specific questions, please feel free to send me a message and I would be happy to try to answer them. I may have forgotten things that I would remember if asked about them.
Hugs and God Bless! K.
