2019-02-20
A possessor in bad faith shall pay for the fruits collected and for those which the lawful possessor might have collected, and shall only have the right to be reimbursed for the necessary expenses incurred in the preservation of the thing. Expenses incurred in improvements for luxury and pleasure shall not be refunded to the possessor in bad faith; but he may remove the objects for which such expenses have been incurred, provided the thing suffers no injury thereby, and the lawful possessor does not prefer to retain them and pay the value they may have at the time he enters into possession.
