An arbitration administrator or arbitrator cannot extend the statutory 30 day period within which a drafting party must pay arbitration fees or forfeit its right to arbitration.  (CCP 1281.98.) The drafting party must pay within 30 days from the date that the fees initially become due.  A later invoice or other attempt to extend the deadline is ineffective.  See also Gallo v. Wood Ranch USA, Inc. (2022) 81 Cal.App.5th 621.
