My fiancé and I are getting married soon and we wanted to know how we would go about relinquishing biological fathers rights and having my fiancé adopt my sion?;)

Not a day goes by and this question, or very similar ones, are asked. So I am going to direct you to the thread concerning this. Questions and answers.

First I would ask how long have you been together, is this something he wants to do the day after you are married ?

Where is the bio father, does he visit, does he pay child support.

But what you do is hire an attorney, who will fill out paper work, and send it to the bio father for him to fill out and sign, If he refuses, there is little you can do, because you have to have his OK.

If he can't be found ( and a search has to be made) it can go ahead
