An Indiana Commercial Security Agreement (CSA) is a contract that creates a security interest in personal property or real estate owned by a borrower, usually in order to secure a loan or other financial obligation. The CSA outlines the rights and obligations of both the lender and borrower, as well as the collateral that will be used to secure the debt. There are three types of Indiana Commercial Security Agreements: Article 9 of the Uniform Commercial Code (UCC) Security Agreement, the Mortgage Security Agreement, and the Chattel Mortgage. The UCC Security Agreement is the most commonly used CSA in Indiana and is used to secure a loan for personal property, such as a car, boat, or furniture. The Mortgage Security Agreement is used to secure a loan for real estate, such as a home or commercial property. The Chattel Mortgage is similar to the UCC Security Agreement, but is used to secure the purchase of a specific item of personal property. All three types of CSA's require the lender to record the agreement in the state's public records in order to be enforceable.
