Article 912

If the devise subject to reduction should consist of real property, which cannot be conveniently divided, it shall go to the devisee if the reduction does not absorb one-half of its value; and in a contrary case, to the compulsory heirs; but the former and the latter shall reimburse each other in cash for what respectively belongs to them.

The devisee who is entitled to a legitime may retain the entire property, provided its value does not exceed that of the disposable portion and of the share pertaining to him as legitime. (821)
