Ind. Code § 32-32-3-11

Sec. 11. An action for partition of a time share unit or camping site may not be maintained except as provided in the time share instrument. If a time share or camping site is owned by two (2) or more persons, an action may be brought for the judicial sale of the time share or camping site.
