[POMPONIUS libro uigensimo quarto ad Quintum Mucium. ] §41.6.3.prSi uir uxori uel uxor uiro donauerit, si aliena res donata fuerit, uerum est, quod Trebatius putabat, si pauperior is qui donasset non fieret, usucapionem possidenti procedere.
[POMPONIUS, from his twenty-fourth book on Quintus Mucius.] If a husband has made a gift to his wife or a wife to her husband, and if a thing belonging to another has been given, it is true, as Trebatius thought, that usucaption runs in favor of the possessor, provided that the donor does not become poorer.
