[MODESTINUS libro septimo differentiarium. ] §26.2.4.prPater heredi instituto filio uel exheredato tutorem dare potest, mater autem non nisi instituto, quasi in rem potius quam in personam tutorem dare uideatur.
[MODESTINUS, from the seventh book on Differences.] A father can appoint a tutor for his son, whether the son is appointed heir or disinherited, but a mother can do so only for a son who is appointed heir, as she is deemed to appoint a tutor for the property rather than for the person.
sed et inquiri in eum, qui matris testamento datus est tutor, oportebit, cum a patre datus, quamuis minus iure datus sit, tamen sine inquisitione confirmatur, nisi si causa, propter quam datus uidebatur, in eo mutata sit, ueluti si ex amico inimicus uel ex diuite pauperior effectus sit.
But it will also be necessary to investigate him who has been appointed tutor by the mother's will, whereas one appointed by a father, even though appointed with less than full legal form, is nevertheless confirmed without investigation, unless the circumstance for which he seemed to be appointed has changed in him, as for example if he has become an enemy instead of a friend, or poorer instead of rich.
