Singer Toni Braxton has filed a complaint with a U.S. bankruptcy court in Los Angeles asking that her contract with her record label, LaFace Records, be declared unenforceable.

Braxton's complaint is the latest development in the singer's on-going legal wrangle with LaFace (see "Toni Braxton Files For Bankruptcy"), and cites a California law known as the "seven-year statute," which prohibits personal-service contracts longer than seven years as a form of indentured servitude.

The law was originally intended to protect movie actors during the heyday of Hollywood's old studio system, but has also been invoked in recent years by acts such as Metallica and the Smashing Pumpkins in their legal battles with record companies.

In her complaint, Braxton further alleges that LaFace set her up with lawyers whose main loyalty was towards the label rather than the singer, and that her tours were turned into "economic disasters."
