Whoever pays the debt of another without that person’s order shall have no right of recourse against the debtor for what they have paid, unless authorized by the court, required by necessity, or it is customary that they act as the debtor’s representative. They shall have no right of recourse against the creditor unless the creditor has discharged the debtor from the debt, even after recovering their debt from the payer.
