The Rules of Golf
The USGA, in conjunction with the R&A in St. Andrews,
Scotland, writes, interprets and maintains the Rules of
Golf to guard the tradition and integrity of the game.
The two organizations are joint authors and owners of
The Rules of Golf and Decisions on the Rules of Golf.
Through an agreement with the R&A, the Rules
jurisdiction of the USGA includes only the United States,
its possessions and Mexico.
