A former Big Law attorney in Houston has sued Gray Reed & McGraw and Houston senior counsel Jack Emmott III, alleging they failed to tell him about a last-minute change in his divorce documents, costing him hundreds of thousands of dollars.

Bradley Raffle, an environmental lawyer who formerly practiced law in Houston at Baker Botts and Pillsbury Winthrop Shaw Pittman, is seeking up to $1 million in damages from Gray Reed and Emmott in a suit filed on Friday in State District Court in Harris County.
