Louisiana Civil Code Tit. II, Art. 1749. Donation of property to be left at death; caducity

When the donation consists of property that the donor will leave at his death, it becomes of no effect and the object thereof thereupon falls to the heirs or legatees of the donor spouse, as the case may be, if the donee predeceases the donor or, once the donor's succession is opened, renounces the donation or is declared unworthy to receive it.
