The Grammy-winning vocal group filed the lawsuit on Wednesday in federal court after negotiations with Anita White broke down in recent weeks. According to the lawsuit, the band is seeking a ruling that their use of the trademark "Lady A" does not infringe on White's alleged trademark rights of the same name. The band is not seeking monetary damages.
The group made up Hillary Scott, Charles Kelley and Dave Haywood announced the name change last month, saying they were regretful for not taking into consideration the word antebellum's associations with slavery.
But White, who has been releasing blues and soul music for years as Lady A, complained publicly that the band never reached out to her before changing their name. Negotiations over the name failed to reach an agreement. A manager for White did not immediately respond to a request for comment.
According to the lawsuit, the band applied for trademarks for the name "Lady A" for entertainment services and for use on clothing back in 2010 and no oppositions were filed by any person or entity.
"When we learned that Ms. White had also been performing under the name Lady A, we had heartfelt discussions with her about how we can all come together and make something special and beautiful out of this moment," said the group in a statement. "We never even entertained the idea that she shouldn't also be able to use the name Lady A, and never will - today's action doesn't change that."
