  • Window-opens date, not a deadline. The petition must be made MORE than one year after the trigger, so file on or after the day following the computed anniversary for a mandatory ('shall') order; before then the order is discretionary (10950(a)). The account's due date is whatever the order specifies (10950(c)); enter it as a court-ordered date.
  • If the clerk's office is closed or inaccessible on the last day (weather, emergency or local closure orders), the deadline may be extended. Check local orders.
