"The subjects required for business law vary from country to country but typically include civil law, contract law, company, and commercial law, insolvency law, and competition/antitrust law.
In the United States, for example, a business lawyer would need to be familiar with the Uniform Commercial Code (UCC), a set of laws governing commercial transactions. The UCC covers everything from sales contracts to secured transactions. Lawyers in other countries may also be required to know their national equivalents of the UCC."
