London, Oct 15 : Martina Navratilova''s ex-''wife'' has filed a lawsuit against the retired tennis ace for allegedly reneging on a financial agreement.

Navratilova married Toni Layton in New Hampshire in 2000, but the union was not official because gay marriage will not be made legal in the state until 1 January, 2010.

The pair, which started dating in the early 1990s, kept on spending time in between houses in Colorado and Florida.

However, Layton has alleged that she was left broke and homeless when Navratilova abruptly ended the relationship and threw her out of the home they shared.

According to a lawsuit recently filed by Layton in Sarasota, Florida, the former couple agreed to "evenly share... all assets earned and obtained by either".

Layton has claimed that Navratilova broke the agreement when she cancelled her ex''s credit cards and kept all the money from their joint accounts.

"It was a complete shock when Martina terminated the relationship. For eight years Toni was Martina''s business partner and domestic partner, but she found herself being manhandled out of the house by Martina''s security guards. She was left homeless and practically penniless," The Daily Express quoted Layton''s attorney Raymond Rafool as telling the National Enquirer.

Layton has asked for compensation amounting to half the value of their shared homes, in addition to the return of her three cars and all gifts she gave to Navratilova during their relationship, estimated to be worth 1 million pounds.

The sports legend''s attorney Barry Greenberg has confirmed the legal action but insists the suit is a "private matter".

"We''re not going to be making any statements," he added. (ANI)
