The cable network picked up 11 episodes of the series back in July.
Common Law was set to have its premiere this year on January 26 but it was delayed to mid-2012 after the USA executives decided the series would do better during summer months.
The series, starring Michael Ealy and Warren Kole, will debut on Tuesday, May 11 at 10/9pm ET on USA.
Common Law follows two detectives (Ealy and Kole) who are good at their job but are complete opposites of each other.
Created by Cormac Wibberley and Marianne Wibberley, the series also features Jack McGee, Lyle Brocato and Sonya Walger.
