A Notice of Overdue Account is a document sent by a creditor to a debtor to inform them that their account is past due. This notice informs the debtor of the amount that is owed, the date the debt is due, and any fees associated with the debt. It is important for the debtor to pay the debt in full by the date provided, or else they may face further legal action. There are two types of Notice of Overdue Account: The Demand Notice and the Final Notice. The Demand Notice is the first notice sent to the debtor, and it informs them of the amount that is owed and the date that the debt must be paid by. The Final Notice is the last notice sent to the debtor, and it informs them that they have failed to pay the debt by the due date and that legal action may be taken if the debt is not paid in full.
