RS 9:315.23: Suspension or modification of child support obligation; secreting of child

If one joint custodial parent or his agent is intentionally secreting a child with the intent to preclude the other joint custodial parent from knowing the whereabouts of the child sufficiently to allow him to exercise his rights or duties as joint custodial parent, the latter may obtain from the court an order suspending or modifying his obligation under an order or judgment of child support. However, such circumstances shall not constitute a defense to an action for failure to pay court- ordered child support or an action to enforce past due child support.
