Custody questions are stressful for any family, but they can be even more confusing when parents were never married. In California, many unmarried parents are unsure who has custody, what rights each parent has, and how the court decides what’s best for the child.
This article explains California custody laws for unmarried parents in simple, easy-to-understand language, so everyday parents and legal professionals can clearly understand their rights and options.
The Starting Point: Custody When Parents Are Unmarried in California
California does not automatically give custody to both parents when a child is born to unmarried parents.
The General Rule
- The mother has automatic legal and physical custody at birth
- The father has no automatic custody or visitation rights until legal paternity is established
This does not mean fathers lack rights—it means the law requires formal steps before those rights apply.
Establishing Legal Parentage (Paternity) in California
Before an unmarried father can request custody or visitation, legal parentage must be established.
How Parentage Can Be Established
- Voluntary Declaration of Parentage
- Signed by both parents (often at the hospital)
- Has the same effect as a court order
- Court Order
- Issued in family court
- May involve genetic testing
Once parentage is established, both parents have:
- Equal legal standing
- The right to seek custody or visitation
- The responsibility to support the child financially
Types of Custody in California
California recognizes two main types of custody:
- Legal Custody
- The right to make major decisions
- Includes education, healthcare, and religious upbringing
- Physical Custody
- Determines where the child lives
- Can be primary or shared
Custody can be:
- Joint (shared by both parents)
- Sole (one parent has primary authority)
How California Courts Decide Custody
California courts decide custody based on the best interests of the child.
Judges consider factors such as:
- The child’s health, safety, and welfare
- Any history of abuse or neglect
- The nature of the child’s relationship with each parent
- Each parent’s ability to provide a stable home
- Willingness to encourage a relationship with the other parent
Courts do not favor mothers over fathers once parentage is established.
Does California Prefer Joint Custody?
California law encourages frequent and continuing contact with both parents, as long as it is safe for the child.
Joint custody is common when:
- Parents can communicate
- Both parents are involved
- There are no safety concerns
However, joint custody is not guaranteed.
Visitation Rights for Unmarried Parents
If one parent has primary physical custody, the other parent is usually granted:
- Scheduled visitation
- Holiday and vacation time
- Phone or video contact
Visitation may be supervised if:
- There is a history of abuse
- Substance abuse is involved
- The child’s safety is at risk
Child Support and Custody Are Separate Issues
A common misconception is that:
- Paying child support guarantees visitation
- Failing to pay support cancels visitation rights
In California:
- Custody and child support are separate legal matters
- A parent may owe support and still have visitation
- Visitation cannot be denied because of unpaid support
Can an Unmarried Father Get Full Custody?
Yes.
Unmarried fathers can receive:
- Sole physical custody
- Sole legal custody
- Or joint custody arrangements
The deciding factor is always the child’s best interests, not the parents’ marital status.
Modifying Custody Orders
Custody orders can be changed if:
- There is a significant change in circumstances
- The change benefits the child
Common reasons include:
- Relocation
- Changes in work schedules
- Safety concerns
- Child’s developmental needs
What Law Firms Should Know (Legal Insight)

- Parentage actions

Key legal considerations include:
