Plain-language explainer

What AB 1978 actually does

The California Equal Shared Parenting Act (2025–2026 session, authored by Assemblymember Johnson (R–63)) changes the starting point in custody cases — not the finish line.

45%

of overnights for each parent is the presumptive floor — a rebuttable presumption, not a mandate

25 mi

both parents must live within 25 miles of the child's school for the presumption to apply

Fit

both parents must be found fit, willing, and able — and courts can deny equal time on clear and convincing evidence, in writing

Honest answers to hard questions

Does this put children at risk in abuse cases?

No. The presumption only applies when both parents are found fit, willing, and able. A judge can deny equal time on clear and convincing evidence that it would be detrimental to the child — including any history of substantiated abuse — and must explain that decision in writing. The safety valve is built into the bill's text.

Does it take away judges' discretion?

No. It sets a starting point, not an ending point. Courts retain full discretion to depart from equal time whenever the evidence shows it would harm the child. What changes is that a fit, loving parent no longer starts from behind.

What about parents who live far apart?

The presumption only applies when both parents live within 25 miles of the child's school. That distance limit exists precisely to prevent impractical orders that would bounce a child across long commutes.

What about infants and very young children?

Fitness, willingness, and ability are assessed for the actual child in the actual case. Courts can and do consider developmental needs; the clear-and-convincing safety valve applies at every age.

When would it take effect?

It applies to custody cases filed on or after January 1, 2027 — it does not reopen existing custody orders.

Is this a fathers'-rights bill?

It's a children's bill. The presumption is gender-neutral: it protects the child's relationship with both fit parents, whoever they are. Decades of research associate meaningful time with both parents with better outcomes for children of divorce.

Convinced? It takes 2 minutes.
