Article 1083
ART. 1083. Every co-heir has a right to demand the division of the estate unless the testator should have expressly forbidden its partition, in which case the period of indivision shall not exceed twenty years as provided in article 494. This power of the testator to prohibit division applies to the legitime. Even though forbidden by the testator, the co-ownership terminates when any of the causes for which partnership is dissolved takes place, or when the court finds for compelling reasons that division should be ordered, upon petition of one of the co-heirs.
