Urgent please need clarification

Once a secured debt is repaid in full, the secured party must, upon written request by the debtor, send a termination statement to the debtor and file a termination statement with all offices that hold the financing statement. A termination statement serves as evidence that the debt has been paid in full. If the debtor makes a written request for the termination statement, the creditor must send the statement within ten days of the date of the request. Even if the debtor does not so request, the secured party must send a termination statement to offices that hold the financing statement within 30 days of the satisfaction of the debt.
