[IDEM libro tertio interdictorum. ] §43.26.22.prSi is, qui pro possessore possideret, precario dominum rogauerit, ut sibi retinere rem liceret, uel is, qui alienam rem emisset, dominum rogauerit: apparet eos precario possidere.
[THE SAME, Interdicts, book three.] If he who was possessing as a possessor should ask the owner by precarium that he be permitted to retain the thing, or if he who had bought another’s property should ask the owner: it is clear that they possess by precarium.
nec existimandos mutare sibi causam possessionis, quibus a domino concedatur precario possidere: nam et si id quod possideas alium precario rogaueris, uideri te desinere ex prima causa possidere et incipere ex precario habere: et contra si possessorem precario rogauerit qui rem auocare ei posset, teneri eum precario, quoniam aliquid ad eum per hanc precarii rogationem peruenit, id est possessio, quae aliena sit.
Nor should those to whom it is granted by the owner to possess by precarium be thought to change the cause of possession for themselves; for even if you should ask another by precarium for that which you possess, you are seen to cease possessing by your former cause and to begin to hold by precarium; and conversely, if he who could recover the thing from the possessor should ask the possessor by precarium, he is bound by precarium, since something has come to him through this request for precarium, that is, possession, which is another's.
§43.26.22.1Si pupillus sine tutoris auctoritate precario rogauerit, Labeo ait habere eum precariam possessionem et hoc interdicto teneri.
If a ward should ask by precarium without the authority of his tutor, Labeo says that he has possession by precarium and is bound by this interdict.
nam quo magis naturaliter possideretur, nullum locum esse tutoris auctoritati: recteque dici 'quod precario habes', quia quod possideat ex ea causa possideat, ex qua rogauerit: nihilque noui per praetorem constituendum, quoniam, siue habeat rem, officio iudicis teneretur, siue non habeat, non teneatur.
For since it is possessed in fact, there is no room for the authority of the tutor; and it is correctly said "what you hold by precarium," because what he possesses, he possesses by that cause under which he made the request; and nothing new should be established by the praetor, since, whether he has the thing, he would be bound by the duty of the judge, or whether he does not have it, he would not be bound.
