La. Civ. Code art. 1480
Current with changes from Acts 3, and 6-45 of the 2024 Legislative Session
When a donation inter vivos or mortis causa is declared null because of undue influence or because of fraud or duress, it is not necessary that the entire act of donation or testament be nullified. If any provision contained in it is not the product of such means, that provision shall be given effect, unless it is otherwise invalid.
