[AFRICANUS libro septimo quaestionum. ] §3.5.45.prMandasti filio meo, ut tibi fundum emeret: quod cum cognouissem, ipse eum tibi emi.
[AFRICANUS, Questions, Book VII] mandated my son to buy a tract of land for you; when I had learned of this, I myself bought it for you.
puto referre, qua mente emerim: nam si propter ea, quae tibi necessaria esse scirem, et te eius uoluntatis esse, ut emptum habere uelles, agemus inter nos negotiorum gestorum, sicut ageremus, si aut nullum omnino mandatum intercessisset, aut Titio mandasses et ego, quia per me commodius negotium possim conficere, emissem.
I think it makes a difference with what intention I bought it. For if it was on account of those things which I knew were necessary for you, and because you were of such a mind that you wished to have it bought, we shall bring actions between us for business managed, just as we would bring them if either no mandate at all had intervened, or you had mandated Titius and I, because I could complete the business more conveniently by myself, had bought it.
si uero propterea emerim, ne filius mandati iudicio teneatur, magis est, ut ex persona eius et ego tecum mandati agere possim et tu mecum actionem habeas de peculio, quia et si Titius id mandatum suscepisset et, ne eo nomine teneretur, ego emissem, agerem cum Titio negotiorum gestorum, et ille tecum et tu cum illo mandati.
But if indeed I bought it for the reason that my son should not be held liable under the action of mandate, it is more correct that, on his account, I also should be able to bring the action of mandate against you, and you should have against me the action concerning the peculium; because even if Titius had undertaken that mandate and, lest he should be held liable on that account, I had bought it, I would bring the action for business managed against Titius, and he against you, and you against him the action of mandate.
idem est, et si filio meo mandaueris, ut pro te fideiuberet, et ego pro te fideiusserim. §3.5.45.1Si proponatur te Titio mandasse, ut pro te fideiuberet, meque, quod is aliqua de causa impediretur quo minus fideiuberet, liberandae fidei eius causa fideiussisse, negotiorum gestorum mihi competit actio.
The same is true also if you mandated my son to become a surety for you, and I became a surety for you. it is proposed that you mandated Titius to become a surety for you, and I, because he was prevented by some cause from becoming a surety, became a surety for the purpose of releasing his obligation, the action for business managed is available to me.
