La. Civ. Code art. 893
Current with changes from the 2024 legislative session, Chs. 3, 6-496, effective on or before 7/1/2024
The property that devolves to the brothers or sisters is divided among them equally, if they are all born of the same parents. If they are born of different unions, it is equally divided between the paternal and maternal lines of the deceased: brothers or sisters fully related by blood take in both lines and those related by half-blood take each in his own line. If there are brothers or sisters on one side only, they take the entirety to the exclusion of all relations in the other line.
