A bit of history is in order. Before the UCC was written, commercial law varied, sometimes greatly, from state to state. This first proved a nuisance and then a serious impediment to business as the American economy became nationwide during the twentieth century. Although there had been some uniform laws concerned with commercial deals—including the Uniform Sales Act, first published in 1906—few were widely adopted and none nationally. As a result, the law governing sales of goods, negotiable instruments, warehouse receipts, securities, and other matters crucial to doing business in an industrial market economy was a crazy quilt of untidy provisions that did not mesh well from state to state.
The UCC is a model law developed by the ALI and the National Conference of Commissioners on Uniform State Laws; it has been adopted in one form or another by the legislatures in all fifty states, the District of Columbia, and the American territories. It is a “national” law not enacted by Congress—it is not federal law but uniform state law.
Initial drafting of the UCC began in 1942 and was ten years in the making, involving the efforts of hundreds of practicing lawyers, law teachers, and judges. A final draft, promulgated by the ALI, was endorsed by the American Bar Association and published in 1951. Various revisions followed in different states, threatening the uniformity of the UCC. The ALI responded by creating a permanent editorial board to oversee future revisions. In one or another of its various revisions, the UCC has been adopted in whole or in part in all American jurisdictions. The UCC is now a basic law of relevance to every business and business lawyer in the United States, even though it is not entirely uniform because different states have adopted it at various stages of its evolution—an evolution that continues still.
