Article 1076
ART. 1076. The co-heirs are bound to reimburse to the donee the necessary expenses which he has incurred for the preservation of the property donated to him, though they may not have augmented its value. The donee who collates in kind an immovable, which has been given to him, must be reimbursed by his co-heirs for the improvements which have increased the value of the property, and which exist at the time the partition is effected. As to works made on the estate for the mere pleasure of the donee, no reimbursement is due him for them; he has, however, the right to remove them, if he can do so without injuring the estate. (n)
