[GAIUS libro sexto ad edictum prouinciale. ] §5.3.39.prUtiles autem necessariaeque sunt ueluti quae fiunt reficiendorum aedificiorum gratia: aut in nouelleta: aut cum seruorum gratia litis aestimatio soluitur, cum id utilius sit quam ipsos dedi: denique alias complures eiusdem generis esse impensas manifestum est.
[GAIUS in his sixth book on the Provincial Edict.] Now, useful and necessary expenses are, for example, those which are incurred for the sake of repairing buildings, or on a young vineyard, or when, for the sake of slaves, the value of the litigation is paid, since this is more useful than surrendering the slaves themselves; finally, it is clear that there are many other expenses of the same kind.
§5.3.39.1Uideamus tamen, ne et ad picturarum quoque et marmorum et ceterarum uoluptariarum rerum impensas aeque proficiat nobis doli exceptio, si modo bonae fidei possessores simus: nam praedoni probe dicetur non debuisse in alienam rem superuacuas impensas facere: ut tamen potestas ei fieret tollendorum eorum, quae sine detrimento ipsius rei tolli possint.
Let us see, however, whether the plea of fraud may not equally benefit us also with respect to the expenses of paintings, marbles, and other luxurious things, provided only we are bona fide possessors; for it will be rightly said to a robber that he ought not to have made superfluous expenses on another's property, provided, however, that the power of removing those things which can be removed without detriment to the thing itself should be granted to him.
