appropriation of payments

In the law of debtor and creditor, appropriation of payments is the application of a particular payment for the purpose of paying a particular debt.

When a creditor has two debts due to him from the same debtor on distinct accounts, the general law as to the appropriation of payments made by the debtor is that the debtor is entitled to apply the payments to such account as he thinks fit; solvitur in modum solventis.
