[IDEM libro quarto ex Plautio. ] §12.6.46.prQui heredis nomine legata non debita ex nummis ipsius heredis soluit, ipse quidem repetere non potest: sed si ignorante herede nummos eius tradidit, dominus, ait, eos recte uindicabit.
[The same, in the fourth book on Plautius.] A person who, in the name of the heir, has paid legacies that are not due out of the money of the heir himself, cannot himself recover them; but if he delivered the money without the knowledge of the heir, the owner (the heir), he says, will rightfully claim it by a vindicatio.
eadem causa rerum corporalium est.
The same rule applies to corporeal things.
