The purpose of the club is to enable its members to play tennis. Membership is reserved primarily for residents of the communes of Mies and Tannay. Children and juniors of active members who are at most 19 years old (as of 31 December of the current year) and who are not domiciled in Mies or Tannay are admitted as members. They may only attain active member status if they meet the criteria set for active members. Members who leave the communes may remain members of TCMT. Residents, their spouses, and their direct descendants may be admitted as members of TCMT. Every active member has the right to vote at assemblies.
