Uniform Commercial Code (UCC)

I. What is the UCC?

The Uniform Commercial Code (UCC), a comprehensive code addressing most aspects of commercial law, is generally viewed as one of the most important developments in American law. The UCC text and draft revisions are written by experts in commercial law and submitted as drafts for approval to the National Conference of Commissioners on Uniform State Laws (referred to as the Uniform Law Commissioners), in collaboration with the American Law Institute. The Commissioners are all attorneys, qualified to practice law, including state and federal judges, legislators and law professors from throughout the United States and its territories. These quasi-public organizations meet and decide whether to endorse these drafts or to send them back to the experts for revision. The revision process may result in several different revisions of the original draft. Once a draft is endorsed, the Uniform Law Commissioners recommend that the states adopt these rules.

The UCC is a model code, so it does not have legal effect in a jurisdiction unless UCC provisions are enacted by the individual state legislatures as statutes. Currently, the UCC (in whole or in part) has been enacted, with some local variation, in all 50 states, the District of Columbia, Puerto Rico, and the Virgin Islands.

II. Organization of the UCC

The rules for each of the transactional areas covered by the UCC are collected into separate parts called an "article." Each article is then arranged systematically  as consecutively numbered parts based upon subtopics.

As of this guide's last update, the types of transactions included within the Code are:

  • Sales (Amended Article 2);
  • Leases (Amended Article 2A);
  • Negotiable Instruments, previously known as Commercial Paper (Revised Article 3);
  • Bank Deposits and Collections (Amended Article 4);
  • Funds Transfers (Article 4A);
  • Letters of Credit (Revised Article 5);
  • Bulk Sales, previously known as Bulk Transfers (Revised Article 6);
  • Documents of Title (Revised Article 7);
  • Investment Securities (Revised Article 8); and
  • Secured Transactions (Revised Article 9).

Article 1 of the Code contains a set of general provisions equally applicable to all subsequent articles. Articles 10 and 11 contain provisions for effective dates, repeals and transitional matters.

The primary sources for UCC research are:

  • the Code itself;
  • the Official Comments of the UCC Permanent Editorial Board (PEB);
  • the Permanent Editorial Board Commentaries; and
  • judicial opinions which interpret and apply the Code, as enacted in a particular state.

Besides the text of the Code itself, the Official Comments are almost universally treated as the most authoritative sources in the construction of the Code sections. The PEB Commentary was introduced in 1990. It seeks to resolve issues and ambiguities raised by the UCC and Official Comments, to resolve issues on which scholarly and judicial opinion differ, and to elaborate on the UCC’s role in relation to other statutes. Note that some Commentary may be superseded by later Code amendments. Lastly, a substantial body of case law exists on the UCC. UCC litigation occurs in both federal and state courts, including bankruptcy courts for matters arising under Article 9. Some Articles are less litigated than others, resulting in limited case law for certain Articles.
