[PAULUS libro primo quaestionum. ] §29.2.88.prGerit pro herede, qui animo adgnoscit successionem, licet nihil attingat hereditarium.
[PAULUS, from the first book of Questions.] He acts as heir who in his mind accepts the succession, even though he touches nothing belonging to the inheritance.
unde et si domum pignori datam sicut hereditariam retinuit, cuius possessio qualisqualis fuit in hereditate, pro herede gerere uidetur: idemque est et si alienam rem ut hereditariam possedisset.
Hence, even if he retained a house given in pledge as if it were part of the inheritance, the possession of which, of whatever sort it was, was in the inheritance, he is deemed to act as heir; and the same is true even if he had possessed another's property as if it were part of the inheritance.
