The opinion of the court was delivered by
Kennedy, J.The nature and application' of set-off seem to have been misapprehended in the court below. Set-off is only applicable when the parties to the action have mutual and independent debts or claims, arising out of separate and distinct contracts against each other; which, therefore, could not be settled by set-off at common law, without the consent of both parties; but, in order to effect this without such consent, where a suit was brought by one against the other, and thereby prevent circuity of action, the defendant is now authorized by statute to liquidate, pr satisfy the debt or claim of the plaintiff, by setting up his own claim against that of the plaintiff, and obtaining a credit for it, and by this means to satisfy the claim of the plaintiff; 1 Rawle 293; Ballentine on Set-off 1. If the defendant, therefore, claims the benefit of a set-off, he impliedly admits the existence of the plaintiff's claim, but desires that it may be extinguished by a set-off of the debt coming to himself from the plaintiff, against it. But if he asserts that he has actually paid the debt claimed by the plaintiff, then it is obvious, that instead of admitting the plaintiff's claim to be still in being, as in case of his claiming merely to have a set-off allowed him, he denies that the plaintiff has any claim at all against him. Seeing, then, that the defendant below did not set up or pretend to have any debt or claim against the plaintiff, no question of set-off could arise in the case. The defendant there merely claimed that the instalment due on the bond, at the time of bringing the action, had been paid, in part, before, and the residue after the commencement of it; and by the endorsements on the bond, which were not controverted, but admitted, he showed that he had actually paid, at different times, in discharge of •the condition of the bond, an amount of money much more than sufficient to satisfy the two instalments for which the action was brought. But the plaintiff below contended, that the • payments, though made on the bond, ought to be first appropriated to the payment of the instalments; which became payable in January of the *257years 1838 and 1S39. The question, therefore, raised on the trial in the court below, would seem to have been one of appropriation, and not of set-off. The money received by the plaintiff below was received by him as paid on the bond. Thus far, at least, an appropriation was made of the money so paid by the parties at the time of paying it. It was, therefore, paid and received on the bond generally, without any specific appropriation being made of it to any of the particular instalments. Then, as no specific appropriation was made by the parties of the money paid, to any particular instalments, it must be left to the law to make it. In doing so, the law will certainly not sanction or adopt a principle which would apply the money paid to instalments which had not become payable at the time of its being paid, because this would be giving the plaintiff the use of the defendant’s money before he had any right to receive it on the claim to which it would be thus applied, and would cause the defendant at the same time to pay interest afterwards, upon the instalments or money which had become payable previously, and was therefore bearing interest until it should be paid. This would seem to have been the effect of the charge of the court to the jury in this case; or, at least, might in many cases produce it. Before the commencement of this action, 171 dollars were paid on the bond: and to apply this money to the instalments of 1838 and 1839, which did not become payable for a year and more after it was paid, would seem inevitably to produce the effect just mentioned; which would be the very height of injustice. The equitable and just rule in such case is, to apply the money towards the payment of the instalments that have become payable at the time, according to the priority of dates at which they respectively become so. This is just; because it must be presumed to have been so intended by the parties, or at least by the debtor and payer, at the times the payments were made; because it would be contrary to reason, and the motives which generally influence human action, to presume that a debtor, in paying money, intended to apply it to the discharge of a debt not bearing interest, and which had not at the time become payable, in preference to a debt which was bearing interest, and had become payable: nor would a creditor be permitted to claim that it should be so applied, without the express consent of the debtor. The court below, therefore, erred in their direction to the jury on this point.
Judgment reversed, and a venire facias de novo awarded.
