UCC Article 9 is a part of the Uniform Commercial Code (UCC) that governs secured transactions in personal property. It outlines the rules for creating, perfecting, and enforcing security interests, which are legal claims on collateral to secure a loan or obligation. This article helps lenders protect their interests when borrowers default on loans. The article applies to various types of collateral, including inventory, equipment, and accounts receivable. It establishes procedures for filing financing statements, which notify others of a lender's security interest. By providing a clear framework, UCC Article 9 promotes consistency and predictability in commercial transactions across different states.
