Foggy Nelson and Matt Murdock founded their own law firm Nelson and Murdock. Then they represented Karen Page who was arrested under suspicion of murdering of Daniel Fisher. They successfully got her out of custody and she decided to join the firm to pay for their help.
The loss of Castle's case, combined with increasing tensions between Murdock and Nelson over Murdock's secret life as the vigilante Daredevil, caused the lawyers to shutter the office.

Following Fisk's incarceration, Nelson decided to found a new law firm with Page's official partnership. Theo Nelson allowed them to use Nelson's Meats to work. Murdock and Page agreed and together started their work to help people.
Upon hearing news reports of Frank Castle had been placed in police custody, Karen Page used her position as Castle's lawyer in order to visit him without Foggy Nelson and Matt Murdock's knowledge. At the Sacred Saints Hospital, she helped Dinah Madani investigate the corpses of the three women supposedly murdered by Castle. With the aid of assistant medical examiner Ed Zatner, the pair found out that the three women were executed at close range, and Castle’s gunfire did not cause their deaths.
With Page being informed of their respective situation, she aided in uncuffing Castle and attempted to reconnect with him only to be rebuffed. Knowing the stakes, Page’s last action before going her separate ways is triggering fire alarms in order to ensure Castle's escape from custody.
