If the biological father wants to do a voluntery relinquishment of his rights, you could file for adoption and termination. Even if he doesn't sign voluntarily, you could ask the court to terminate his rights because he has not provided support for the child. Depending on the grounds for termination, it might take longer than if he would voluntarily give up his rights so your fiance can adopt.
