Is the biological father’s consent necessary?
Most states require that the biological father consent to an adoption if his identity is known. Depending on state law, the consent of the biological father, even if not married to the biological mother, may still be required, particularly when he has provided support in the past or has been involved in the child’s upbringing. If he has not seen or supported the child for an extended period, his consent may in some cases not be required.
