The short answer is, yes. A father is entitled to notice of an adoption. He can give his consent, or the adopting family can move to terminate his parental rights. An adoption agency or adoption attorney can help you obtain the father's consent, or explain the grounds or adoption without consent. The right attorney can connect you with a reputable adoption agency, or an adoptive family who can help with your medical and legal expenses. Please act soon. Delay could limit your options.
