§51 — Improvements made by bona fide holders under defective titles

When the transferee of immoveable property makes any improvement on the property, believing in good faith that he is absolutely entitled thereto, and he is subsequently evicted there from by any person having a better title, the transferee has a right to require the person causing the eviction either to have the value of the improvement estimated and paid or secured to the transferee, or to sell his interest in the property to the transferee at the then market value thereof, irrespective of the value of such improvement. The amount to be paid or secured in respect of such imp rovement shall be the estimated value thereof at the time of the eviction. When, under the circumstances aforesaid, the transferee has planted or sown on the property crops which are growing when he is evicted therefrom, he is entitled to such crops and to free ingress and egress to gather and carry them.
