How California Family Law Treats Unmarried Couples with Children

California has a large number of couples who build families without getting married. When these relationships end or when legal issues arise involving children, many parents wonder how California family law applies to them. The good news is that California provides strong protections for unmarried parents, ensuring that children receive the same rights and support as those born to married couples. At Williams, Drexler, & Mand PC, we can provide legal assistance to the California public navigating parentage, custody, child support, and related family law matters.


Establishing Legal Parentage


For unmarried couples, establishing legal parentage (also known as “paternity”) is often the first step. When parents are not married at the time of a child’s birth, the law does not automatically recognize the father as a legal parent. Parentage can be established in two main ways:


  • Signing a Voluntary Declaration of Parentage (VDOP): When both parents agree, this document gives the child the same legal rights as if the parents were married.
  • A Court Order: If there is disagreement or uncertainty, the court may require genetic testing before issuing a parentage order.


Once parentage is established, both parents gain legal rights and responsibilities regarding their child.


Custody and Visitation Decisions


California law treats custody matters for unmarried couples the same as it does for divorcing couples. The court prioritizes the child’s best interests, considering factors such as stability, health, safety, and each parent’s involvement in the child’s life. Types of custody include:


  • Legal Custody: The right to make major decisions for the child.
  • Physical Custody: Where the child lives day-to-day.


Courts may award joint or sole custody depending on the circumstances. A formal parenting plan helps prevent conflict and provides structure for both parents.


Child Support Obligations


Both parents are financially responsible for their child, regardless of marital status. California uses statewide guidelines to calculate child support, based on:


  • Each parent’s income
  • Time spent with the child
  • Health insurance and childcare costs


Once support is ordered, it is legally enforceable, and failure to comply can lead to wage garnishment or other enforcement actions.


Parental Rights and Responsibilities


Unmarried fathers sometimes worry they have fewer rights, but once parentage is legally established, both parents have equal standing. This includes the right to request custody and visitation, as well as the responsibility to provide financial support.

Likewise, unmarried mothers should understand that without a legal parentage order or VDOP, the court cannot issue enforceable custody or support orders. Taking the steps to establish parentage protects both parents and the child.


When Legal Guidance Is Important


Unmarried couples often face unique challenges, especially when relationships become strained or when one parent moves away, withholds visitation, or disputes financial obligations. At Williams, Drexler, & Mand PC, we help California families understand their rights, secure formal court orders, and protect their children’s well-being.
