Article 84 - Imputation of payments

(1) An Obligor owing several monetary obligations to the same Obligee may specify at the time of payment the debt to which he intends the payment to be applied. However, the payment discharges first any expenses, then interest due and finally the principal.
(2) If the Obligor makes no such specification, the Obligee may, within a reasonable time after payment, declare to the Obligor the obligation to which he imputes the payment, provided that the obligation is due and undisputed.
(3) In the absence of imputation under Article 84(1) or (2), payment is imputed to that obligation which satisfies one of the following criteria and in the order indicated:
(A) an obligation which is due or which is the first to fall due;
(B) the obligation for which the Obligee has least security;
(C) the obligation which is the most burdensome for the Obligor; and
(D) the obligation which has arisen first.
(4) If none of the criteria in Article 84(3) apply, payment is imputed to all the obligations proportionally.
