Moradi Neufer is a full-service California family law firm with an office in Irvine. Our Irvine paternity lawyers represent both mothers and fathers in establishing legal parentage, securing child custody, obtaining child support, and resolving contested paternity disputes throughout Orange County.
When a child is born to unmarried parents in Irvine, there is no automatic legal relationship between the father and the child. That might seem like a technical legal detail, but it has real and lasting consequences for everyone involved: the father has no legal right to custody or visitation, the child has no legal claim to the father’s financial support or inheritance, and the mother cannot compel financial contributions without a court order. Establishing legal paternity changes all of that, and it starts with having the right legal team on your side.
At Moradi Neufer, our Irvine paternity lawyers represent both mothers and fathers in all aspects of parentage proceedings throughout Orange County. Whether you’re a father wanting to establish your parental rights, a mother seeking child support from an unwilling co-parent, or a parent disputing a paternity claim, we handle these cases with the legal precision and local court familiarity they require. If paternity is the first step on your road to protecting your family, let’s talk about what that road looks like.
In California, being a biological parent and being a legal parent are not the same thing. Until paternity is legally established, an unmarried father has no enforceable rights, and the child has no legally recognized relationship with that father. This affects more than just custody and visitation.
Here is what legal paternity establishes for the child:
And for the parents:
• For fathers: legal paternity is the gateway to seeking custody, visitation, and meaningful involvement in the child’s life
• For mothers: legal paternity enables enforcement of child support, medical support orders, and shared parenting responsibilities
California law provides several pathways to establish legal paternity under the Uniform Parentage Act, codified in California Family Code Sections 7600 and following. Our Irvine paternity lawyers can walk you through which method applies to your situation.
The most straightforward route is a Voluntary Declaration of Parentage, sometimes called a VDOP or in older terminology a Voluntary Declaration of Paternity. This is a form signed by both parents, typically at the hospital shortly after the child’s birth, that creates a legal parental relationship without court involvement. Once signed and filed with the California Department of Child Support Services under the Parentage Opportunity Program (POP), it has the same legal effect as a court judgment of paternity.
Important caveat: a VDOP can be rescinded within 60 days of signing or before a court makes an order based on it, whichever comes first. After that window closes, rescinding requires a court order and a showing of fraud, duress, or material mistake of fact. If you signed a VDOP and now have doubts, or if you are disputing one that was signed, speak with us immediately.
When the parents cannot agree, or when one parent denies paternity, either parent can file a Petition to Establish a Parental Relationship (Form FL-200) with the Orange County Superior Court at the Lamoreaux Justice Center. The court may order genetic testing to determine the biological relationship. DNA testing used in California courts achieves over 99.99% accuracy through accredited labs such as LabCorp or Identigene. Critically, an at-home or pharmacy DNA test will not be admissible in court due to chain-of-custody requirements. Our attorneys coordinate court-approved testing and ensure all results are properly documented for the record.
If a party refuses to submit to court-ordered genetic testing, under California Family Code Section 7551, the court can sanction that party and may presume legal parentage against them. Refusal is not a viable strategy and our team will pursue every available remedy if your co-parent refuses to cooperate.
California law recognizes “presumed parentage” in certain situations, independent of biology. For example, a person who was married to the mother at the time of the child’s birth, who signed the birth certificate, or who received the child into their home and openly held the child out as their own may be presumed to be the legal parent. Presumptions can be rebutted, but doing so requires specific legal action within strict timeframes. If you believe a presumed parentage claim is incorrect, or if someone is challenging your presumed status, this is a matter that requires immediate legal attention.
Establishing paternity is not the finish line. It’s the starting point for resolving a full set of related legal issues that directly affect your child’s day-to-day life and your relationship with them.
Once paternity is legally established, both parents have standing to seek custody and visitation. California courts evaluate custody based on the best interest of the child, considering factors such as each parent’s ability to provide care, the child’s existing relationships, and the stability of each parent’s home environment. Our child custody attorneys at Moradi Neufer help newly recognized parents negotiate parenting plans and, when necessary, litigate custody at the Lamoreaux Justice Center.
California child support is calculated using a statewide guideline formula that accounts for each parent’s income and the percentage of time each parent spends with the child. Once paternity is established, the court can enter a child support order. Our child support lawyers ensure support is calculated correctly, that all income sources are accurately disclosed, and that the order is enforceable.
After a court judgment of paternity is entered, either parent can request that the father’s name be added to the child’s birth certificate by submitting Form VS-22, Application to Amend a Birth Record, to the local Registrar. Our team guides clients through this process as part of completing the paternity case.
Not every paternity case is straightforward. Some situations involve genuine disputes, strategic denials, or complex legal presumptions that require experienced litigation. Our Irvine paternity lawyers are prepared to handle all of the following contested scenarios.
If the alleged father denies being the biological parent, we file the parentage action, obtain a court order for genetic testing through an accredited lab, and present the results to the court. A genetic test showing 99%+ probability of paternity creates a rebuttable presumption of legal parentage under California law. We move efficiently through this process to minimize delays for both the client and the child.
If you are named as a father but believe you are not the biological parent, time matters. California law imposes strict deadlines on challenging a VDOP or a court judgment of paternity. In general, a parentage action must be filed before the child turns 18, but challenges to specific presumptions or declarations have much shorter windows. If you have any doubt, contact our office immediately so we can assess your options before any deadline passes.
Sometimes paternity is disputed between two or more potential fathers, or there are competing legal presumptions (for example, a presumed father based on marriage and a biological father who is a different person). California courts resolve these conflicts by weighing which parentage serves the best interest of the child. These cases require skilled legal navigation, and our team has the experience to handle them.
If you signed a VDOP or were named in a prior paternity judgment and now have evidence that you are not the biological father, you may be able to seek disestablishment of paternity. The legal standard is demanding and requires showing fraud, duress, or material mistake of fact. Courts also consider whether setting aside paternity serves the child’s best interest. This is not a process to attempt without legal counsel.
