La. Code Civ. Proc. art. 3362
At any time prior to the homologation of the final tableau of distribution, a majority of the heirs of an intestate decedent whose succession is under administration may be sent into possession of all or part of the property of the succession upon their filing a petition for possession as provided in Articles 3001 through 3008 excluding any provisions of Article 3004 to the contrary, except that the proceeding shall be contradictory with the administrator. Upon the filing of such a petition the court shall order the administrator to show cause why the petitioners should not be sent into possession, and shall order that the petitioners be sent into possession unless the administrator or any heir shows that irreparable injury would result, and upon a showing that adequate assets will be retained in the succession to pay all claims, charges, debts, and obligations of the succession. If a majority of the heirs are sent into possession of a part of the property, the administrator shall continue to administer the remainder.
