Betterment, petition.

If a judgment of eviction is rendered against defendant, within 60 days thereafter, or if he or she has appealed, within 20 days after filing the mandate affirming the judgment, defendant may file in the court in which the judgment was rendered a petition setting forth that:

(1) Defendant had been in possession and that he or she or those under whom defendant validly derived had permanently improved the value of the property in controversy before commencement of the action in which judgment was rendered;

(2) Defendant or those under whom defendant validly derives held the property at the time of such improvement under an apparently good legal or equitable title derived from the English, Spanish, or United States Governments or this state; or under a legal or equitable title plain and connected on the records of a public office or public offices; or under purchase at a regular sale made by an executor, administrator, guardian or other person by order of court; and

(3) When defendant made the improvements or purchased the property improved, he or she believed the title which he or she held or purchased to the land thus improved to be a good and valid title. The petition shall demand that the value of the improvements be assessed and compensation awarded to defendant therefor.
