The Florida Notice of Assignment of Security Interest is an important legal document used in financial transactions, specifically in the context of secured loans. When a borrower pledges collateral to secure a loan, this notice informs all relevant parties about the assignment or transfer of the security interest to another entity. In Florida, there are two main types of Notice of Assignment of Security Interest that commonly arise: the Uniform Commercial Code (UCC) written notice and the recorded notice. Both types serve the same purpose of notifying interested parties about the assignment, but they differ in terms of delivery method and filing requirements. The UCC written notice is typically used in private transactions where the security interest is not recorded with a government agency. This type of notice involves the written communication of the assignment to the debtor, informing them of the change in the secured party. It is crucial to provide specific details such as the original loan agreement, the collateral involved, and the new secured party's contact information. Although not legally required, it is advisable to send this notice via certified mail to ensure proof of delivery. On the other hand, the recorded notice is used when the security interest has already been recorded with the appropriate government agency, such as the Florida Secretary of State. This notice requires the completion of specific forms, including the assignment document itself, and payment of the relevant recording fees. By recording this notice, the assignee can establish a priority claim over any subsequent creditors or claimants attempting to assert rights over the collateral.
