[ULPIANUS libro septuagensimo sexto ad edictum. ] §39.5.3.prEt generaliter hoc in donationibus definiendum est multum interesse, causa donandi fuit an condicio: si causa fuit, cessare repetitionem, si condicio, repetitioni locum fore.
[ULPIANUS in the seventy-sixth book on the Edict.] And generally, this must be defined in donations, that it makes a great difference whether there was a motive for donating or a condition: if there was a motive, recovery does not lie; if a condition, there will be room for recovery.
