P.R. Laws tit. 31, § 1467
If, when good faith ceases to exist, there are any natural or cultivated fruits still ungathered, the possessor shall have the right to recover the expenses he may have incurred in their production, and, moreover, to a part of the net proceeds of the crop in proportion to the duration of his possession.
The cost shall be distributed, in like manner, pro rata between the two possessors.
The owner of the thing may, if he wishes, grant to the possessor in good faith the right to complete the cultivation and harvesting of growing fruits, as indemnity for his part of the cost of cultivation and net proceeds; the possessor in good faith who, from any motive, does not care to accept this concession, forfeits the right to be otherwise indemnified.
