La. Civ. Code art. 1595
Current with operative changes from the 2024 Third Special Legislative Session
All legacies that lapse, and are not disposed of under the preceding Articles, accrete ratably to the universal legatees.
When a general legacy is phrased as a residue or balance of the estate without specifying that the residue or balance is the remaining fraction or a certain portion of the estate after the other general legacies, even though that is its effect, it shall be treated as a universal legacy for purposes of accretion under this Article.
