Let me rephrase my question my fiance (man) wants to adopt my son when we are married?

To be safe, let things die down with the despute re your fiance and his ex first. After you get married, wait six months to show the court he provides support for you and your child without the bio dad's help. Then petition for termination of the sperm donor's parental rights. Even if the slouch isn't listed on the birth certificate, unless you doent just cause, he can always show up like an *** later just to be a hater.
