What is the difference between the Common law of contracts and Uniform Commercial Code (UCC) law?
There are a number of differences. One of the differences pertains to what activities or transactions are covered by the Common law or Uniform Commercial Code (UCC) law.
Common law covers services, like real estate and employment contracts. UCC law covers material transfers of goods and securities.
Another difference is that changes to a Common law contract negates and cancels the entire contract while in UCC law minor changes are accommodated.
