Child custody; creating a rebuttable presumption of joint child custody. Effective date.

SB 1580 creates a default presumption that joint custody is in a child's best interest, requiring courts to assume it unless evidence shows otherwise. It mandates that parents submit detailed parenting plans covering living arrangements, support, healthcare, and school placement before a custody decision. The bill also establishes strong exceptions: courts must presume sole custody is better if abuse, domestic violence, stalking, or harassment has occurred, or if a parent is required to register as a sex offender. These changes apply to all Oklahoma family court cases involving minor children.
