Here's my situation:

I've gotten back with my boyfriend of 8 years and we're now engaged. When we get married, he wants to adopt my 8 month old son and change my son's last name to his.

My son has his biological father's last name. The bio father completed an Affidavit of Parentage when my child was 4 months old. He didnt do it at the hospital because he had to go out of town 12 hours after our son was born.

Can my fiance adopt my son if the biological father refuses to give up parental rights? Can I change my baby's last name without the biological father's consent? (We were never married.) HELP! I live in Michigan.
