La. Civ. Code art. 1309

Current with changes from the 2024 legislative session effective on or before 7/1/2024, from Acts 1-3, 6-671
Section 1309 - Partition between possessors in common

It is not indispensable to be owner in common in order to be able to support the action of partition; possession alone, when it is lawful and proceeds from a just title, will support it.

Thus, usufructuaries of the same estate can institute among themselves the action of partition.
