Absent a court order stating that your husband "to be" cannot see his child without the supervision of a social worker he has the legal right to see the child per any existing court order of visitation or child custody as well as any agreement with the child's mother that he may have.From what you have written, I do not see how you or your husband "to be" could get in trouble with the court unless there is a court order precluding him contact with the minor absent a social worker being present.
