Criminal Defense Lawyer in Orange County
Over 20 years of experience. A proven record in Orange County courts.
Two decades of standing beside people in the hardest moments of their lives.
When you're facing a criminal charge — or picking up the pieces as a victim of one — you don't need a firm. You need a lawyer who knows your name, knows the courthouse, and answers when you call.
William J. Duffy has spent more than twenty years practicing criminal law in Orange County. He has built his reputation the only way it can be built in this field: case by case, in courtrooms across the county, earning results for clients when the stakes could not be higher.
Duffy Law, PC represents both those accused or suspected of criminal wrongdoing and the victims of crime — a rare dual perspective that means Will understands how prosecutors think, how cases are built, and where they fall apart. Whether the matter is a DUI, a serious felony, or a pre-charge investigation, every client receives the same thing: clear guidance, honest assessment, and relentless advocacy.
Will handles every case personally. There are no junior associates learning on your file, and no case managers standing between you and your attorney. When you hire Duffy Law, you hire Will Duffy.

Both Sides of the Courtroom
Few defense attorneys have stood on both sides of a criminal case. That perspective is your advantage.
If You've Been Charged or Are Under Investigation
An arrest is not a conviction. From DUI to serious felony charges — and even before charges are filed — we intervene early, protect your rights, challenge the evidence, and fight for the best possible outcome: dismissal, reduction, or acquittal.
If You've Been Harmed by a Crime
Victims deserve a voice, too. We help victims of criminal wrongdoing understand their rights, navigate the justice system, and pursue accountability — with the same clarity and strength we bring to every matter.
