Commercial law explained: sales, negotiable instruments, secured transactions and the Uniform Commercial Code as each state has adopted it.
The Uniform Commercial Code is a model law written by the Uniform Law Commission and the American Law Institute. It has force only because each state legislature enacted it and codified it into the state’s own statutes — and every state has done so. All 50 states, the District of Columbia, Puerto Rico and the U.S. Virgin Islands have enacted it — Louisiana has not adopted Article 2 (Sales) or Article 2A (Leases).
Our pages identify the UCC article involved — for example Article 3 (negotiable instruments) and Article 9 (secured transactions) — and point you to your state’s enacted version. See where each state codified the UCC.

Most commercial law in the United States is state law. However, it looks similar from state to state because of the Uniform Commercial Code.
The UCC is a model law. The Uniform Law Commission and the American Law Institute wrote it, and every state then enacted it into its own statutes. As a result, a section like § 3-301 or § 9-406 has a matching section in each state’s code, sometimes with local changes.
Our guides follow the articles that matter most. For example, Article 3 covers notes and other negotiable instruments, and Article 9 covers security interests and the sale of receivables. You can read the official model text of the Uniform Commercial Code online. Then check your own state’s enacted version.
Finally, commercial disputes turn on details. For your own matter, talk to a licensed attorney.
