Shurtleff and the law firm Troutman Sanders made the announcement in a news release issued Friday.
The 600-lawyer-strong firm says Shurtleff will complement its Washington-based regulatory compliance and government litigation practice.
Shurtleff will join a team that includes former chief lawyers for other states and the federal government.
Shurtleff was first elected in 2000. He decided not to run for re-election this November and is being succeeded by his chief deputy, John Swallow.
