San Diego Paternity and Father's Rights Attorney

Being an unmarried father shouldn’t mean being shut out of your child’s life. Yet without legal paternity established, you have no enforceable rights to custody, visitation, or decision-making—even if you’re listed on the birth certificate. Many fathers discover this harsh reality only after being denied access to their children or facing child support obligations without any parental rights.

At Neinas Smolina APC, we support your drive to be an active, involved parent. California law provides strong protections for fathers’ rights, but only after you navigate the legal requirements to establish paternity. Our experienced attorneys guide fathers through this critical process, ensuring you secure the legal standing necessary to build and maintain meaningful relationships with your children.

This Guide Covers:

  • Establishing legal paternity in California
  • Father’s rights to custody and visitation
  • Child support obligations and calculations
  • Emergency custody procedures
  • San Diego County’s specific requirements

Understanding your rights and options empowers you to take decisive action, whether you’re seeking to establish paternity voluntarily or facing a contested situation. Although California law treats mothers and fathers equally once paternity is established, getting to that point may take a long time and requires following specific procedures and meeting strict deadlines.

We help fathers throughout San Diego County secure their legal rights while focusing on what matters most—building strong, lasting bonds with their children.

Common Concerns for Unmarried Fathers in San Diego

You may fear that without marriage, you have no legal right to see your child or make important decisions about their upbringing. The prospect of paying child support while being denied any time with your child feels fundamentally unfair. Many fathers worry that courts automatically favor mothers, leaving them fighting an uphill battle regardless of their involvement or commitment.

The legal maze seems overwhelming: forms, deadlines, DNA tests, court hearings. Being listed on the birth certificate DOES NOT guarantee your rights. These anxieties intensify when every day apart means missing irreplaceable moments in your child’s life.

The good news is California family law provides a clear route to equal parental rights. Fathers have full standing to seek custody, visitation, and shared decision-making for their child.


Why Mothers and Fathers Start Differently

The Legal Reality of Parental Rights at Birth

When a child is born in California, parental rights aren’t distributed equally. Mothers gain automatic legal rights at birth: they can make medical decisions, enroll the child in school, apply for benefits, and relocate without permission. This automatic recognition exists whether the parents are married, living together, or have no relationship at all.

For married couples, fathers receive the same automatic rights through the marital presumption. The law assumes a husband is the legal father of any child born during marriage. But for unmarried fathers, the situation is different. Without taking legal action, they have no rights, even if they’re listed on the birth certificate, actively involved, or providing financial support. 

However, when an unmarried father signs a Voluntary Declaration of Paternity (VDOP), it carries the same legal weight as a court judgment. But he may still need to go to court to enforce that judgment and secure actual visitation rights.

This disparity isn’t about favoring one parent over another. It reflects the biological certainty of motherhood versus questions that can arise about paternity. While many people still believe mothers automatically get favored in custody battles, California law has evolved significantly. Today’s courts focus on the child’s best interests regardless of gender, and mothers sometimes find themselves needing to defend their parenting time just as fathers do. The state provides clear pathways for both parents to establish and protect their rights.

Why Establishing Paternity Matters for Everyone

Establishing paternity benefits children, mothers, and fathers alike. Children gain financial security through both parents’ support obligations, inheritance rights, access to family medical history, and eligibility for benefits like Social Security or veterans’ benefits. Most importantly, they gain the legal right to relationships with both parents.

For mothers, established paternity means shared financial responsibility and the ability to pursue child support. For fathers, it transforms them from legal strangers into parents with enforceable rights to custody, visitation, and decision-making authority.


Understanding Paternity in San Diego County

Parentage action establishes the legal father-child relationship, creating enforceable rights and responsibilities. In California, being a biological father doesn’t automatically grant legal rights—courts distinguish between biological connection and legal recognition. This distinction becomes crucial when seeking custody, visitation, or defending against child support claims.

California fathers must take affirmative steps to establish paternity through voluntary declarations of paternity signed at the hospital at child’s birth or through court proceedings.

California law recognizes several categories of fathers with different legal standings:

Presumed fathers gain automatic rights through marriage to the mother, signing a Voluntary Declaration of Paternity (VDOP), or receiving the child into their home and openly holding them out as their own.

Biological fathers have genetic connections but no legal rights without establishing paternity.

Alleged fathers are named as possible fathers but haven’t established legal status.

“Kelsey S.” fathers (named after the California Supreme Court case Adoption of Kelsey S.) demonstrate full commitment to parental responsibilities, thus gaining constitutional protection to be fathers even without formal parentage establishment. Such responsibilities include attempting to provide support, communicate with the child, and take on other responsibilities.

Once paternity is established through any recognized method, unmarried fathers gain rights identical to married or divorced fathers. The law makes no distinction based on marital status regarding custody, visitation, or decision-making authority.

San Diego County divides family law cases among four courthouses: Central (downtown), South County (Chula Vista), East County (El Cajon), and North County (Vista). Each location accepts filings with your assigned zip code. When you file your Petition for Parentage, you will need to complete the local SDSC Form D-049 (venue declaration) indicating that your zip code allows you to file at the specific court. Understanding both state law and local procedures is important. It will ensure your case proceeds efficiently.


California’s Paternity Laws and Requirements

California family law provides multiple pathways to establish a father’s custody and visitation rights while protecting children’s interests.

Uniform Parentage Act (Family Code §7600-7730)

California’s Uniform Parentage Act establishes that parent-child relationships extend equally to every child and parent, regardless of marital status. This fundamental principle ensures unmarried fathers can achieve the same legal standing as married fathers, eliminating historical discrimination while maintaining procedural requirements for establishing those rights.

Presumptions of Paternity (Family Code §7611)

California law creates several presumptions of paternity that grant immediate legal father status. These include being married to the mother at conception or birth, signing a valid Voluntary Declaration of Paternity, or receiving the child into your home and openly holding them out as your own. Each presumption carries different evidentiary weight and procedural implications.

Marital Presumption (Family Code §7540)

The marital presumption creates a conclusive presumption that a husband is the father of children conceived during marriage. This powerful presumption can only be challenged within two years of the child’s birth, and only through specific procedures. This provision is designed to protect established family relationships.

Voluntary Declaration Process (Family Code §7570-7577)

The Voluntary Declaration of Paternity (VDOP) is very important. Signed on form CS-909, typically at the hospital or later at vital records offices, this declaration carries the same force as a court judgment. Fathers have only 60 days to rescind the declaration. After that, challenges require proving fraud, duress, or material mistake of fact—a high legal standard.

Genetic Testing Standards

When paternity is disputed, courts order genetic testing through approved facilities. Modern DNA testing achieves over 99% accuracy, effectively resolving biological questions. Testing typically costs around $500 and provides results within 3-5 business days. Courts generally require the party disputing paternity to pay testing costs if results confirm fatherhood.

Jurisdictional Flexibility

Unlike divorce proceedings requiring six months of California residency, paternity cases have no residency requirements. California courts have jurisdiction if the child was conceived, born, or artificially inseminated in the state. The Uniform Child Custody Jurisdiction and Enforcement Act (UCCJEA) governs multi-state issues, with the child’s “home state” (where the child lived for six consecutive months) typically having jurisdiction.


Establishing Paternity in San Diego County

Establishing paternity through California courts is designed to protect both fathers’ rights and children’s interests. 

Step 1: Petition for Parentage or Custody & Support

The Voluntary Declaration of Paternity (VDOP) using form CS-909 establishes paternity when both parents agree. You can sign this declaration at the hospital when your child is born or later at vital records offices. The VDOP has the same legal effect as a court judgment. Remember that you have only 60 days to change your mind. After that window closes, challenging the declaration requires proving fraud, duress, or material mistake of fact.

If you have a VDOP, but the mother is preventing you from seeing your child, you will need to file a petition for custody and support (FL-260) asking for a parenting plan. You will need to attach the VDOP to your petition. 

For contested situations or when the mother refuses to acknowledge paternity, you’ll need to file a parentage petition (FL-200). You can request parenting orders within this petition. This formal process provides a forum to present evidenc and obtain paternity judgment and orders for a parenting plan.

Step 2: File and Serve Papers

Court proceedings begin with filing essential documents at one of San Diego County’s four family law courthouse locations. For Custody and Support, you will need the FL-260 petition, FL-210 summons, FL-105 UCCJEA declaration, and SDSC Form D-049 venue declaration. For parentage, you’ll need the FL-200 petition, FL-210 summons, FL-105 UCCJEA declaration, and SDSC Form D-049 venue declaration. The first filing fee is $435; income-based fee waivers are also available.

After filing, you must personally serve the other parent through a process server or sheriff. The respondent has 30 days to file a response. Missing this deadline for the respondent can result in default judgment, so proper service and timely response are critical.

Step 3: Genetic Testing (If Needed)

When paternity is disputed, courts order DNA testing through approved facilities. Modern genetic testing achieves over 99% accuracy, effectively resolving biological questions. Testing typically costs around $500, with results available within 3-5 business days. Courts generally require the party disputing paternity to pay if results confirm fatherhood.

Step 4: Attend Hearings

Timeline varies significantly based on case complexity. Uncontested cases typically resolve within 6-8 months. Contested cases without trial average 6-12 months, while those proceeding to trial can extend 12-18 months. San Diego County requires mandatory mediation through Family Court Services (FCS) before custody hearings, adding additional time. It typically takes one month from the time you attend FCS appointment for the FCS recommendation to issue.  

Step 5: Obtain Orders

Your paternity judgment establishes legal father status and can also include custody orders, visitation schedules, and child support orders. You’ll also receive authority to amend the birth certificate through form VS-22. These orders carry legal weight, providing enforceable rights and responsibilities.

What Changes When Paternity Is Established in San Diego

Understanding what changes once paternity is established—and what rights you lack without it—helps you make informed decisions about timing and strategy.

After Paternity Is Established

Legal paternity transforms your status from biological father to legal parent with enforceable rights. You gain equal standing to seek custody and visitation, with no gender preference in California courts. The same “best interest of the child” standard under Family Code Section 3011 applies to all parents, evaluating factors like health, safety, welfare, frequent and continuing contact with both parents, and the child’s preferences when age-appropriate.

Child support obligations follow California’s statewide formula CS = K[HN – (H%)(TN)], considering both parents’ income, time-share percentages, and allowable deductions. 

Before Paternity is Established

Without established paternity, you have no legal relationship with your child. You cannot seek custody or visitation through the courts. You cannot make medical or educational decisions. Yet you may still face child support obligations if paternity is later established retroactively. 

Property Considerations for Unmarried Parents

Property acquired during your relationship remains separately owned unless specifically titled jointly. You have no automatic interest in assets accumulated by your partner, regardless of the relationship duration.

While “Marvin claims” based on the 1976 case Marvin v. Marvin allow unmarried partners to seek property division and spousal support through express or implied agreements, these require a court order. Outside of the Marvin action, unmarried parents cannot receive alimony regardless of financial disparity.


Your Rights and Options as a Father in San Diego

California family law protects your relationship with your children. Choosing the right approach depends on your specific circumstances and the level of cooperation from the other parent.

Emergency Custody Orders

You may need emergency orders when there is a risk of immediate harm to your child or risk that the child would be removed from California. Under these circumstances, you can seek emergency ex parte orders. These ex parte orders require detailed declarations with specific incidents and dates. While the standard is high, San Diego courts take genuine emergencies seriously.

Protection Strategies

Act immediately to establish paternity and/or seek custody orders. Delays only compromise your position. Document everything: school visits, medical appointments, support provided, and time spent with your child. This evidence proves invaluable in custody proceedings.

Seek temporary orders early in your case. These establish status quo arrangements and step-up parenting plans. Even imperfect temporary orders will provide you more time with your child than no orders at all.

Support Resources

San Diego County offers extensive resources for fathers navigating paternity proceedings. The Family Law Facilitator provides free assistance at all courthouse locations. Legal Aid Society of San Diego assists income-eligible clients at (877) 534-2524. The Department of Child Support Services helps establish parentage and support orders for mothers, with extended hours including Saturday service.

Common Questions About Paternity in San Diego

Do I have rights if I’m on the birth certificate? Being listed on the birth certificate doesn’t establish legal paternity for unmarried fathers in California. You need either a signed Voluntary Declaration of Paternity or a court order.

Can I get custody as an unmarried father? Yes, once you establish legal paternity, you have equal rights to seek custody. California courts apply the same “best interests” standard to all parents, with no preference based on gender or marital status.

What if the mother won’t let me see my child? Without established paternity, you have no legal recourse. Once you file for paternity and it is established, denying court-ordered visitation is illegal and can result in contempt charges and custody modifications favoring the denied parent.

Can DNA tests be required? Courts routinely order genetic testing when paternity is disputed. Modern DNA tests exceed 99% accuracy. If you’re proven to be the father after contesting paternity, you’ll likely pay the testing costs.
