A Letter: File Notice Settle is a document used by a creditor to notify a debtor that a creditor has received full payment of the debt. It is usually sent after the payment has been made and is sent as a way to confirm that the debt has been settled. The letter should include the date of payment, the amount of payment, the account number, and any other relevant information. There are two types of Letter: File Notice Settle: a full and final settlement letter, and a partial settlement letter. A full and final settlement letter is sent when the debtor has paid the full amount of the debt, while a partial settlement letter is sent when the debtor has only paid a portion of the debt.
