La. Civ. Code art. 487
Current with operative changes from the 2024 Third Special Legislative Session
For purposes of accession, a possessor is in good faith when he possesses by virtue of an act translative of ownership and does not know of any defects in his ownership. He ceases to be in good faith when these defects are made known to him or an action is instituted against him by the owner for the recovery of the thing.
