If the encumbered person is a reserved heir of the disposing person, the charge may only be imposed on the available portion.
The donee may, however, accept, in the deed of gift or subsequently in a deed drawn up under the conditions provided for in Article 930, that the charge encumbers all or part of his reserve.
The legatee may, within a period of one year from the day on which he became aware of the will, request that his share of the reserve be, in whole or in part, released from the charge. Failing this, he must assume its execution.
The charge on the encumbered person’s share of the reserve, with his consent, automatically benefits, to that extent, all his children born and unborn.
