What Is a Paternity Action?

A paternity action is a court case filed to establish who a child's parent is legally. It's a common misconception that only the father can file a paternity action.  Either parent can file the action to officially define the relationship between a parent and child. The legal determination of parentage is critical because an unmarried parent generally has no enforceable way to secure custody, visitation, or child support, even if that parent's name is on the birth certificate or a hospital declaration was signed. 

How Paternity Can Be Automatically Presumed

When a child is born to a married couple, or within a set period after death, annulment, or divorce, the husband is presumed to be the legal father. The presumption of paternity also applies to unmarried couples when a man has openly held out the child as his own and taken the child into his home in a family-like setting. 

For unmarried couples, a man can be presumed to be the legal father if he takes the child into his home and openly treats the child as his own. This includes letting the child call him "dad" or telling others the child is his. However, this presumption can still be challenged with evidence like DNA testing, so you should always confirm your status with an attorney.

Ways to Establish Paternity When It Is Not Presumed

When the marital or holding-out presumption of paternity doesn't apply, you must establish parentage another way. Several legal routes can recognize a man as a child's father, and each depends on different facts and proof. Some are based on a signed agreement, some on court findings, and others on the parties' conduct before and after the child's birth. 

In cases involving same-sex parents, parentage may also be established through a paternity action under California law. However, those cases are often highly fact-specific and should be reviewed with an attorney.

• Voluntary declaration of paternity (VDOP): A signed VDOP can establish legal parentage, and it may usually be rescinded within a short window after signing.
• Genetic testing in a paternity action: A court can order DNA testing to determine biological parentage and resolve custody or support issues.
• Parentage by estoppel: This applies when a man has acted as the child's parent and the law prevents him from denying that relationship later.
• Artificial insemination with written consent: If both parties signed a written agreement before insemination, the sperm donor is generally not treated as a legal parent.

Who Can File a Paternity Action?

While many believe that only fathers can file paternity actions, they can also be filed by the mother to prove fatherhood of her child, a man who believes he is the father, a man who has been identified as a potential father, child support agencies assisting a parent, or a relative with specific interests in the child's life in some circumstances. 

Curious family members may not file paternity actions simply to gain access to private information. However, in some cases, such as if the grandparents are taking care of the child, they may be able to file a paternity action. An attorney can help you determine if you qualify.

What a Paternity Judgment Means for Custody, Visitation, and Support

Once parentage is legally established, both parents can request custody and visitation orders. Either parent can then seek visitation time with the child and have a say in major decisions about their life. A San Diego custody attorney can help schedule time with the child. The court will issue orders based on what's in the child's best interests.

Legal parentage also establishes a duty to the child. Both parents must financially support the child. California uses a standard child support guideline formula based on both parents' incomes and how much time each parent spends with the child. A paternity judgment is not just about rights; it also governs parental responsibility.

Sharing Childcare, Medical, and Pregnancy-Related Costs

Child support is more than a simple monthly payment; it includes the child's needs and the other parent's child-related expenses. For example, if a parent needs to pay for childcare so they can work, pursue education, or attend job training, the cost of care is generally shared between the parents. Similarly, unreimbursed medical expenses such as  copays and prescriptions are also generally split between the parents.

A mother can also ask the court to have the father share the pregnancy- and childbirth-related expenses as part of the paternity action. The mother must make the request through the proper legal channels and support the request with evidence. An attorney can help you gather the proof and present the request correctly so the court can consider it. We recommend addressing "add-on" expenses from the beginning, rather than after the case is settled.

Where to File: Jurisdiction in a Paternity Case

Where you file a paternity action matters; filing in the wrong location can lead to case rejection and slow the entire process. California generally has jurisdiction to enter a paternity judgment when the child was conceived, born, or conceived through artificial insemination within the state. If none of those events occurred in California, the state where at least one took place is typically the correct place to file. 

A San Diego court may still have the ability to hear a paternity case even when the child was conceived or born in another county, depending on how long the child has lived in San Diego. However, a declaration under the Uniform Child Custody Jurisdiction and Enforcement Act is generally required with the filing to legally establish jurisdiction.

Confirming jurisdiction matters significantly when parents conceived or gave birth in another state, then relocated to San Diego. Military families often have ties to multiple states, so jurisdiction can become complex. Always confirm your jurisdiction with an attorney before you file to avoid unnecessary delays.
