The Grascals have been named in a lawsuit brought by their former management company, Entertainment Evolution.
The company is run by Kirt Webster, owner of Webster PR who, according to a piece in the Nashville City Paper, alleges that the popular Nashville-based bluegrass band has reneged on a verbal commitment made in 2010.
A claim of $120,000 is sought in this action.
The Grascals have declined comment.
