Randy,
I located this site, which is a summary of CA adoption law:
http://www.adoptionsolutions.com/general/state laws/ca_law.htm
Consent to Adoption
The following parties must consent to the adoption:
1.
the mother;
2.
the man who is presumed to be the father by marriage or attempted marriage to the mother at the time of birth or within 300 days prior to birth; or has been legitimated as the father by other specified means;
3.
Department of Social Services or county adoption agency, where parental consent
is not necessary; and
4.
an adoptee who is over 12 years of age.
No consent is required in the following circumstances:
1.
one parent has been awarded custody and the other parent has not communicated with nor paid support and care of the child for 1 year, then the custodial parent alone may consent, as long as the noncustodial parent is given notice of the hearing;
2.
when parental rights have been terminated or the parent has voluntarily given up his or her rights to the child;
3.
when the parent has deserted the child; or
4.
when the parent has given up the child for adoption by relinquishing rights to the Department or a licensed agency.
The court shall order that relevant persons and agencies make efforts to identify the alleged natural father. Any potential natural father who is identified must be given notice of the hearing. After the natural father, or more than one natural father, is notified, they must claim paternity within thirty days and appear at the hearing or their parental rights will be terminated. If the natural father does appear in court, the court will determine if he is in fact the father and then determine if it is in the child's best interest for the father to retain his parental rights. If so, the father's consent will be required. If not, the court will terminate the father's parental rights.....
If after making efforts, the court is unable to identify the natural father, the court will enter an order terminating the unknown father's parental rights. (This information regarding alleged father's rights is found in Sections 7610 to 7670 of the California Civil Code).
I don't know if this helps, but it provides some information you may not have had.
