The Short Answer

California courts decide child custody based on the child’s best interest, considering health, safety, welfare, and the child’s relationship with each parent.

What the Law Says

California law requires courts to award custody based solely on the child’s best interest — not parental preferences, gender, or past conduct unless it affects the child’s well-being.

The court must consider all relevant factors affecting the child’s health, safety, and welfare. This includes the nature and amount of contact with both parents, any history of abuse, substance use, or criminal behavior, and the child’s wishes if they are of sufficient age and capacity to reason.

There is no legal presumption favoring mothers or fathers. Both parents start on equal footing. The court may award sole or joint legal and/or physical custody depending on what serves the child’s best interest.

Before making a custody order, the child must have lived in California for at least six months (or three months if removed from an abusive situation), satisfying the Uniform Child Custody Jurisdiction and Enforcement Act (UCCJEA) home-state requirement.

What Courts Have Said

California appellate courts have repeatedly emphasized that the child’s best interest is the only controlling standard — and that trial courts have broad discretion in weighing evidence to reach that determination.

In re Marriage of Burgess

California Supreme Court · 1996

Confirmed that the 'best interest' standard gives trial courts wide discretion; appellate courts will not overturn custody decisions absent abuse of discretion.

In re Marriage of LaMusga

California Supreme Court · 2004

Clarified that a parent’s intent to relocate does not automatically trigger a change in custody — the focus remains on how the move affects the child’s best interest.

What to Do

File a Request for Order (Form FL-300) in the county where the child has lived for the past 6 months.

Attend mandatory mediation through Family Court Services before the hearing.

Prepare evidence showing your ability to support the child’s health, safety, and welfare (e.g., school records, witness statements, counseling reports).

If your child is 14 or older, ask them whether they wish to address the court directly (per Family Code § 3042).

Consider consulting a family law attorney or self-help center — many counties offer free or low-cost assistance.
