Arbitration in the United States is governed by the Federal Arbitration Act of 1925 (FAA, codified at 9 U.S.C. 1 et seq.), which requires courts to compel parties who agree to arbitration to participate in binding arbitration, the decision from which is binding upon the parties. Since the passage of the FAA, both state and federal courts have examined arbitration clauses, as well as other statutes involving arbitration clauses, for validity and enforceability.
