Is California a mother state? Can a dad get primary custody?
Quick answer
No. California law tells judges not to consider a parent’s sex when deciding what is in a child’s best interest, so a father asks for primary physical custody under the same standard as a mother. The judge decides based on the child’s health, safety, and welfare and the other best-interest factors in the Family Code.

What the law says
Family Code section 3040(c): “The court shall not consider the sex, gender identity, gender expression, or sexual orientation of a parent, legal guardian, or relative in determining the best interest of the child under subdivision (a).” Section 3011(b) says the same for the best-interest factors, and section 3020(d) declares it state policy.
Section 3040(a)(1) puts custody to both parents jointly or to either parent first in the order of preference, and says that in granting custody to either parent the court “shall consider, among other factors, which parent is more likely to allow the child frequent and continuing contact with the noncustodial parent, consistent with Sections 3011 and 3020.” Section 3020(a) makes the child’s “health, safety, and welfare” the court’s primary concern.
Before any order, section 3010(a) says: “The mother of an unemancipated minor child and the father, if presumed to be the father under Section 7611, are equally entitled to the custody of the child.” A father who is not yet a legal parent needs parentage established first.
Is California a 50/50 custody state?
Not by default. Section 3040(e) “establishes neither a preference nor a presumption for or against joint legal custody, joint physical custody, or sole custody.” Section 3080 creates a presumption that joint custody is in the child’s best interest, subject to section 3011, where the parents have agreed to joint custody or agree in open court.
What to do next
Ask for the custody you want on form FL-311 (item 2a is physical custody, the person the child will regularly live with) and explain in your declaration how your proposed schedule serves your child. If you were never married and parentage has not been established, start there.
