[ULPIANUS libro secundo disputationum. ] §26.1.7.prSi filius familias tutor a praetore datus sit, si quidem pater tutelam agnouit, in solidum debet teneri, si non adgnouit, dumtaxat de peculio.
[ULPIANUS, On Disputations, Book 2.] If a filius familias is given as a guardian by the praetor, if indeed the father has acknowledged the guardianship, he must be held liable in solidum; if he has not acknowledged it, only to the extent of the peculium.
adgnouisse autem uidetur, siue gessit siue gerenti filio consensit siue omnino attigit tutelam.
Moreover, he is deemed to have acknowledged it, whether he administered it himself, or consented to his son who was administering it, or touched upon the guardianship in any way at all.
unde cum quidam filio scripsisset, ut diligenter tutelam gereret, 'cum scias', inquit, 'periculum ad nos pertinere', dixi hunc quoque uideri adgnouisse: plane si solum monuit filium, non uidetur agnita.
Hence, when a certain person had written to his son to administer the guardianship diligently, saying, "since you know that the risk pertains to us," I said that this person also was deemed to have acknowledged it. Obviously, if he only admonished his son, it is not deemed to have been acknowledged.
