A California parentage case determines a legally significant relationship. Once legal parentage is established, the determination can affect child custody, visitation, support, and other parental rights and responsibilities.

That makes it important to identify everyone who may have a legitimate claim to parentage. California parentage proceedings can involve more than the two people who initially disagree about whether someone is a parent. In some cases, additional presumed, genetic, intended, or other potential parents must receive notice or become parties to the proceeding.

Why Do All Potential Parents Matter in a California Parentage Case?

Failing to address another person’s potential parental rights can create serious complications.

Depending on the circumstances, relevant individuals can include a gestational or biological mother, a presumed parent, an alleged genetic parent, or people whose parental claims arise from assisted reproduction.

When competing claims exist, the court may need all necessary parties before it can properly determine who has legal parentage rights.

For example, when someone seeks to establish biological parentage while another person already qualifies as a presumed parent, the existing presumed parent’s rights cannot simply be ignored.

Do Potential Parents Have a Right to Notice?

California parentage law requires notice to specified people who may have legally recognized claims involving the child.

These can include a child’s natural parent, people qualifying under applicable parentage presumptions, certain parents recognized through assisted-reproduction provisions, and alleged genetic parents when they are not legally barred from establishing parentage.

Qualifying individuals must be given notice and an opportunity to be heard and may be entitled to joinder when they request it.

Notice is important because a parentage judgment can substantially affect a person’s future parental rights and obligations.

Can the Child Be a Party to the Parentage Case?

Yes.

When the child is at least 12 years old, California law requires the child to be made a party to the parentage action and represented by a court-appointed guardian ad litem.

When the child is younger than 12, the court may make the child a party. The court may also appoint private counsel to represent the child’s interests in appropriate circumstances.

Identifying the Right Parties Can Prevent Future Parentage Disputes

Parentage litigation is not simply about obtaining genetic test results.

California recognizes several legal paths to parentage, and more than one person may potentially assert parental rights. A case that overlooks a presumed or otherwise legally significant parent can leave unresolved issues that surface later.

Identifying potential parents at the beginning of a California paternity or parentage case can help ensure that everyone entitled to notice has an opportunity to participate and that the resulting judgment meaningfully resolves the child’s legal parental relationships.
