Cal. FAM § 8604

(a) Except as provided in subdivision (b), a child having a presumed father under Section 7611 shall not be adopted without the consent of the child’s birth parents, if living. The consent of a presumed father is not required for the child’s adoption unless the person became a presumed father as described in Chapter 1 (commencing with Section 7540) or Chapter 3 (commencing with Section 7570) of Part 2 of Division 12, or subdivision (a), (b), or (c) of Section 7611 before the mother’s relinquishment or consent becomes irrevocable or before the mother’s parental rights have been terminated.

(b) If one birth parent has been awarded custody by judicial order, or has custody by agreement of both parents, and the other birth parent for a period of one year willfully fails to communicate with, and to pay for, the care, support, and education of the child when able to do so, then the birth parent having sole custody may consent to the adoption, but only after the birth parent not having custody has been served with a copy of a citation in the manner provided by law for the service of a summons in a civil action that requires the birth parent not having custody to appear at the time and place set for the appearance in court under Section 8718, 8823, 8913, or 9007.

(c) Failure of a birth parent to pay for the care, support, and education of the child for the period of one year or failure of a birth parent to communicate with the child for the period of one year is prima facie evidence that the failure was willful and without lawful excuse. If the birth parent or parents have made only token efforts to support or communicate with the child, the court may disregard those token efforts.

(d) (1) If the birth mother of a child for whom there is not a presumed father leaves the child in the physical care of a licensed private adoption agency, in the physical care of a prospective adoptive parent who has an approved preplacement evaluation or private agency adoption home study, or in the hospital after designating a licensed private adoption agency or an approved prospective adoptive parent in a signed document, completed with a hospital social worker, adoption service provider, licensed private adoption agency worker, notary, or attorney, but fails to sign a placement agreement, consent, or relinquishment for adoption, the approved prospective adoptive parent or the licensed private adoption agency may apply for, and the court may issue, a temporary custody order placing the child in the care and custody of the applicant.

(2) A temporary custody order issued pursuant to this subdivision shall include all of the following:

(A) A requirement that the applicant keep the court informed of the child’s residence at all times.

(B) A requirement that the child shall not be removed from the state or concealed within the state.

(C) The expiration date of the order, which shall not be more than six months after the order is issued.

(3) A temporary custody order issued pursuant to this subdivision may be voided upon the birth mother’s request to have the child returned to the birth mother’s care and custody.
