The time for filing the complaint, petition, or any pleading may be enlarged by the court for good cause shown, but may not be enlarged by more than 10 additional days or 30 additional days for partitions, nor more than once, unless the default was occasioned by accident over which the party applying had no control, or by the fraud of the opposing party.
