The South Carolina UCC-1ad Financing Statement Addendum is a document used to supplement a UCC-1 Financing Statement. It is used to provide additional information on the debtor and secured party, and to list any additional collateral being secured in the transaction. This document is filed with the South Carolina Secretary of State. The South Carolina UCC-1ad Financing Statement Addendum comes in two versions: Standard and Short Form. The Standard Form is used when the debtor or secured party is a corporation, partnership, or other organization, and when additional collateral is being listed. The Short Form is used when the debtor or secured party is an individual, or when no additional collateral is being listed. Both forms must be signed by the debtor and secured party.
