Billie Jean King Cup Regulations 2026 — the world women's team competition, the counterpart to the Davis Cup.
| Edition | 2026 |
| Length | 151 pages |
The regulations follow the same layout as the Davis Cup: the competition and the system under which it is staged; governance (the Board of Directors, the Billie Jean King Cup Committee, the Executive Director, the final host, the tournament director); officials, with a separation of the powers of the referee, the federation's event manager, the official organiser, the security officer, the media manager and the visiting team's host; and then entry into the competition and the eligibility of nations and players.
Disputes arising from both competitions fall within the jurisdiction of the internal review body and the federation's independent tribunal; the procedure for both is set out in this same body of regulations.
