The onetime owners of a Kennesaw-based company are seeking more than $33 million in a legal malpractice suit against Womble Carlyle Sandridge & Rice and four lawyers over what the plaintiffs claim was a mishandled corporate sale.

The former owners of American Viatical Services (AVS) sued the Womble firm, three partners—John “Sandy” Smith, Robert Ambler Jr. and James Connelly—and former partner Bernard Coleman Jr., who left the firm in 2012.
