An overdue payment, also known as an ARREAR (6 letters) or ARREARAGE (9 letters), is a payment that has not been made on time. It is a debt that has been incurred and is now past due. This type of payment can be the result of a missed deadline, a lack of funds, or any other reason why the payment was not made on time. The consequences of an overdue payment can vary depending on the situation, but typically involve additional fees or interest charges.
