A person may, during his life, allocate all or some of his heirs with property from his money, and that allocation is binding on the rest of the heirs, provided that what was allocated to the heir is equal to his or her inheritance share on the date of death.
But if the value of what was allocated to the heir exceeds his inheritance share, the increase is considered as a will for the heir as it is only executed if the heirs authorize it after the death of the testator.
