The Billie Jean King Cup final will be a knockout this year, with the final to be held in Seville on November 20th.
The extended nine-day event will temporarily overlap with the men's Davis Cup Final 8, which begins in Malaga on the eve of the Billie Jean King Cup final.
The International Tennis Federation (ITF) said the aim of revamping the women's event was to “maximize visibility” and create “two weeks of World Cup tennis” in Andalusia.
Great Britain defeated France at Le Portel in April to book their place in the Billie Jean King Cup final. Canada is the defending champion, with Iga Swiatek, Coco Gauff and Naomi Osaka potentially facing Poland, the United States and Japan, respectively.
The lineup of the eight teams that will be the centerpiece of Davis Cup will not be finalized until September. Britain will face opposition from Canada, Argentina and Finland if it attempts to qualify in Manchester.
The Billie Jean King Cup finals have been held over six days, with 12 teams divided into four groups, with the winners competing in the semi-finals.
This year's changes will see four teams earn byes into the top eight, with eight other countries vying for a place in the quarter-finals.
The Seville tournament begins on Tuesday, November 12, three days after the conclusion of the WTA Finals in Riyadh, Saudi Arabia.
This will give the players time to travel and get used to the conditions in southern Spain. World No. 1 Swiatek missed the 2022 and 2023 Billie Jean King Cup Finals because her schedule did not allow her time to prepare following the WTA Finals in Texas and Mexico.
The first six days of the women's team competition will clash with the men's ATP Finals in Turin, but the ITF hopes the midweek semi-finals and finals will be well attended.
The drawing for the new style Billie Jean King Cup Final will be held on April 30th.
