The professional creditor is required to inform any guarantor who is a natural person of the principal debtor’s default from the first payment incident not regularised within one month of the due date of this payment, on pain of forfeiture of the guarantee of interest and penalties accrued between the date of this incident and the date on which he was informed.
In relations between the creditor and the guarantor, payments made by the debtor during this period are charged in priority to the principal of the debt.
