Two big players in information governance and e-discovery law, Redgrave and Nelson Mullins Riley & Scarborough, announced Tuesday that they will combine, effective Dec. 1, in one of the largest law firm mergers to date this year.

With the combination, Am Law 100 firm Nelson Mullins aims to offer clients one of the country’s largest information governance and e-discovery law practices, an area it says is increasing in demand as companies generate more and more data.
