IN SUO ORDINE
in suo ordine (in s[y]oo-oh or-d<<schwa>>-nee). [Latin] Hist. In his order.
βIn suo ordine …. A cautioner who is entitled to the benefit of discussion can only be called upon, for fulfilment of the obligation which he guaranteed, in his order β that is, after the principal creditor has been discussed. So, also, an heir can only be made liable for the moveable debts of his ancestor, after the executor who succeeded to the moveable estate has been discussed, and where the moveable estate has proved insufficient to meet those debts.β John Trayner, Trayner’s Latin Maxims 277 (4th ed. 1894).
