Rules & Regulations

The rules of tennis may be found online in Friend at Court. These rules cover the size of the court, legal rackets, how to keep score, etc. Sometimes in tennis, you find yourself in odd situations. Your hat may fall off, a bird may fly into a ball or your opponents may grunt excessively. Situations like this are covered in The Code, which is also found in Friend at Court.

No league in our litigious society would be complete without regulations! We have lots of them from the national to the local levels. They are listed below.

The Columbia Tennis League welcomes all people who play, watch, support or enjoy the game of tennis into our events, programs, membership and leadership and will not discriminate against any person on the basis of age, sex, race, ethnicity, creed, sexual orientation, color, physical condition or national origin.  Moreover, we believe that the growth of tennis hinges on effective outreach to groups that have not traditionally been heavily involved in the sport and we will actively solicit and support the participation of such groups.
