Nearly 10 years ago, four grandchildren of the long-deceased co-founder of Rollins Inc.  sued their uncle and father, claiming they improperly seized control and “locked up” the assets of four family trusts containing billions of dollars in assets.

On Monday, a trial deciding the fate of the fortune of the grandfather, O. Wayne Rollins, began in Fulton County Superior Court. It is expected to last three weeks, featuring H. Lamar “Mickey” Mixson, Timothy Rigsbee and Jason Carter of Bondurant, Mixson & Elmore for the plaintiffs and James Lamberth, William Withrow, Keith Barnett and Alan Bakowski of Troutman Sanders for the defendants.
