How to Start a Paternity Action in Los Angeles

When parents are not married at the time of a child’s birth, California law requires them to legally establish parentage before the courts can issue any orders regarding custody, visitation, or child support. Whether you are seeking to assert your parental rights or protect your child’s access to support and stability, starting a paternity action is often the first legal step—and it's one you shouldn’t take lightly.


At M.C. Law, P.C., we help clients throughout Los Angeles understand the process, navigate the legal system, and fight for the parenting rights they deserve.


What Is a Paternity Action?

A paternity action, also known as a parentage case, is a legal process to determine who the legal parents of a child are. Establishing parentage is essential before a court will issue any orders for:


  • Legal custody (decision-making rights)
  • Physical custody (where the child lives)
  • Visitation schedules
  • Child support


Once legal parentage is established, both parents gain equal rights and responsibilities regarding the child—whether or not they were ever in a relationship.


Who Can File a Paternity Case?

In California, either parent may file a Petition to Establish Parental Relationship. Common situations where a parent may want to initiate this legal action include:


  • A mother seeking child support from the father
  • A father seeking custody or visitation rights
  • A parent trying to resolve disputes regarding the child’s legal status


Important: In same-sex parenting situations, if the parents were not married when the child was conceived or born, a paternity action may also be required to establish legal parentage.


The Process of Starting a Paternity Case

  1. File a Petition
    The case begins when one parent files a Petition to Establish Parental Relationship with the family court.
  2. Serve the Other Parent
    The responding party must be officially served with the petition and has
    30 days to file a Response.
  3. Optional: Request Temporary Orders
    During the case, either party may request temporary orders for
    custody, visitation, or support while the final case is being resolved.
  4. DNA Testing (if necessary)
    If paternity is in dispute, the court may order
    genetic testing to confirm whether the alleged father is the biological parent. Note: At-home or private tests are not admissible—only court-ordered tests are valid.
  5. Final Orders and Judgment
    After parentage is legally established, the court can issue final orders addressing
    custody, visitation, and support.
