Acceptilatio
In Ancient Roman civil law, acceptilatio is defined to be a release by mutual interrogation between debtor and creditor, by which each party is exonerated from the same contract. In other words, acceptilatio is the form of words by which a creditor releases his debtor from a debt or obligation, and acknowledges he has received that which in fact he has not received (veluti imaginaria solutio). It is equivalent to the modern acceptilation.
