debet et detinet
debet et detinet (dee-bet ordeb-et et det-i-net ordet-[schwa]-n[schwa]t). [Law Latin] Hist. He owes and detains. • This phrase was used in declarations in actions for debt when the original creditor sued the original debtor. The declaration stated that the defendant “owes to” as well as “detains from” the plaintiff the debt or thing in question; thus, the action was said to be “in the debet et detinet.” But if the action was brought against someone other than the original debtor (such as an executor, for a debt due from the testator), then the action was said to be “in the detinet alone.” Cf. DETINET.
