(a) Authority to declare; duty to inquire (§ 316.2, 726.4)
The juvenile court has a duty to inquire about and to attempt to determine the parentage of each child who is the subject of a petition filed under section 300, 601, or 602. The court may establish and enter a judgment of parentage under the Uniform Parentage Act. (Fam. Code, § 7600 et seq.) Once a petition has been filed to declare a child a dependent or ward, and until the petition is dismissed or dependency or wardship is terminated, the juvenile court with jurisdiction over the action has exclusive jurisdiction to hear an action filed under Family Code section 7630.
(b) Parentage inquiry (§§ 316.2, 726.4)
At the initial hearing on a petition filed under section 300 or at the dispositional hearing on a petition filed under section 601 or 602, and at hearings thereafter until or unless parentage has been established, the court must inquire of the child’s parents present at the hearing and of any other appropriate person present as to the identity and address of any and all presumed or alleged parents of the child. Questions, at the discretion of the court, may include the following and others that may provide information regarding parentage:
(1) Has there been a judgment of parentage?
(2) Was the mother married or did she have a registered domestic partner at or after the time of conception?
(3) Did the mother believe she was married or believe she had a registered domestic partner at or after the time of conception?
(4) Was the mother cohabiting with another adult at the time of conception?
(5) Has the mother received support payments or promises of support for the child or for herself during her pregnancy or after the birth of the child?
(6) Has a man formally or informally acknowledged parentage, including the execution and filing of a voluntary declaration of parentage or paternity under Family Code section 7570 et seq., and agreed to have his name placed on the child’s birth certificate?
(7) Has genetic testing been administered, and, if so, what were the results?
(8) Has the child been raised jointly with another adult or in any other co-parenting arrangement?
(c) Voluntary declaration
If a voluntary declaration as described in Family Code section 7570 et seq. has been executed and filed with the California Department of Child Support Services, the declaration establishes the parentage of a child and has the same force and effect as a judgment of parentage by a court. A person is presumed to be the parent of the child under Family Code section 7611 if the voluntary declaration has been properly executed and filed.
(d) Issue raised; inquiry
If, at any proceeding regarding the child, the issue of parentage is addressed by the court:
(1) The court must ask the parent or the person alleging parentage, and others present, whether any parentage finding has been made, and, if so, what court made it, or whether a voluntary declaration has been executed and filed under the Family Code;
(2) The court must direct the court clerk to prepare and transmit Parentage Inquiry—Juvenile (form JV-500) to the local child support agency requesting an inquiry regarding whether parentage has been established through any superior court order or judgment or through the execution and filing of a voluntary declaration under the Family Code;
(3) The office of child support enforcement must prepare and return the completed Parentage Inquiry—Juvenile (form JV-500) within 25 judicial days, with certified copies of any such order or judgment or proof of the filing of any voluntary declaration attached; and
(4) The juvenile court must take judicial notice of the prior determination of parentage.
(e) No prior determination
If the local child support agency states, or if the court determines through statements of the parties or other evidence, that there has been no prior determination of parentage of the child, the juvenile court must take appropriate steps to make such a determination.
(1) Any alleged father and his counsel must complete and submit Statement Regarding Parentage (Juvenile) (form JV-505). Form JV-505 must be made available in the courtroom.
(2) To determine parentage, the juvenile court may order the child and any alleged parents to submit to genetic tests and proceed under Family Code section 7550 et seq.
(3) The court may make its determination of parentage or nonparentage based on the testimony, declarations, or statements of the alleged parents. The court must advise any alleged parent that if parentage is determined, the parent will have responsibility for the financial support of the child, and, if the child receives welfare benefits, the parent may be subject to an action to obtain support payments.
(f) Notice to office of child support enforcement
If the court establishes parentage of the child, the court must sign Parentage— Finding and Judgment (Juvenile) (form JV-501) and direct the clerk to transmit the signed form to the local child support agency.
(g) Dependency and delinquency; notice to alleged parents
If, after inquiry by the court or through other information obtained by the county welfare department or probation department, one or more persons are identified as alleged parents of a child for whom a petition under section 300, 601, or 602 has been filed, the clerk must provide to each named alleged parent, at the last known address, by certified mail, return receipt requested, a copy of the petition, notice of the next scheduled hearing, and Statement Regarding Parentage (Juvenile) (form JV-505) unless:
(1) The petition has been dismissed;
(2) Dependency or wardship has been terminated;
(3) The alleged parent has previously filed a form JV-505 denying parentage and waiving further notice; or
(4) The alleged parent has relinquished custody of the child to the county welfare department.
(h) Dependency and delinquency; alleged parents (§§ 316.2, 726.4)
If a person appears at a hearing in dependency matter or at a hearing under section 601 or 602 and requests a judgment of parentage on form JV-505, the court must determine:
(1) Whether that person is the biological parent of the child; and
(2) Whether that person is the presumed parent of the child, if that finding is requested.

Plain-English Summary

The court does not wait to be asked. It has a duty to inquire about and try to determine the parentage of every child who is the subject of a petition, and it may enter a judgment of parentage under the Uniform Parentage Act. Once a petition is filed, the juvenile court has exclusive jurisdiction over a parentage action while the case is open.

The inquiry starts at the initial hearing in a dependency case, or at disposition in a delinquency case, and continues at later hearings until parentage is settled. The court asks the parents present, and anyone else who might know, about the identity and address of every presumed or alleged parent. The rule then lists the kind of questions that help: whether a judgment already exists, whether the mother was married or in a registered domestic partnership at or after conception, whether she believed she was, whether she was cohabiting, whether support was paid or promised, whether anyone acknowledged parentage formally or informally or agreed to go on the birth certificate, whether genetic testing was done, and whether the child has been raised in a co-parenting arrangement.

A properly executed and filed voluntary declaration has the force of a judgment, and the person who signed it is presumed to be the child’s parent.

Where the issue is raised, the court asks what has already been decided, has the clerk send form JV-500 to the local child support agency, and takes judicial notice of any prior determination that comes back. The agency has 25 judicial days to answer, with certified copies attached.

If there has been no prior determination, the court makes one. Any alleged father and his counsel complete form JV-505, which must be available in the courtroom; the court may order genetic testing; and it may decide parentage on testimony, declarations or statements. It must warn any alleged parent that a finding of parentage carries a duty of financial support, and may lead to a support action if the child receives welfare benefits. A finding of parentage is recorded on form JV-501 and sent to the local child support agency.

Alleged parents get notice. The clerk mails each named alleged parent, at the last known address by certified mail with return receipt, a copy of the petition, notice of the next hearing, and form JV-505 — unless the petition has been dismissed, the case has ended, the alleged parent has already denied parentage and waived notice, or they have relinquished the child to the welfare department. If an alleged parent appears and asks for a judgment on form JV-505, the court must decide whether they are the biological parent and, if asked, whether they are the presumed parent.

Frequently Asked Questions

Does the juvenile court have to look into who a child’s parents are?

Yes. The rule imposes a duty to inquire about and attempt to determine the parentage of every child who is the subject of a petition under section 300, 601 or 602, and the inquiry continues at hearings until parentage is established.

What is the effect of a voluntary declaration of parentage?

Once properly executed and filed with the California Department of Child Support Services, it establishes parentage with the same force and effect as a court judgment, and the signer is presumed to be the child’s parent.

How is an alleged parent notified?

The clerk sends the petition, notice of the next scheduled hearing, and form JV-505 by certified mail, return receipt requested, to the alleged parent’s last known address — unless the case has ended, the alleged parent has already denied parentage and waived notice, or has relinquished the child to the county.

Can the court order genetic testing?

Yes. To determine parentage the juvenile court may order the child and any alleged parents to submit to genetic tests, proceeding under the Family Code.

What must an alleged parent be told before a parentage finding?

That a finding of parentage carries responsibility for the child’s financial support, and that if the child receives welfare benefits the parent may face an action to obtain support payments.
