There was a time when California judges gave preference to a mother in child custody cases. The reason for the preference was called the Tender Years Doctrine. The assumption was that mothers were the primary caregivers for children, so mothers should receive custody. However, the Tender Years Doctrine was abandoned a long time ago. California does not give preference to either parent in a child custody case. Each parent enters the court on an equal footing.
