Best Criminal Defense Lawyer in NJ and ..Great Friend!

Mark has been not only an advisor to me but also a great friend who has represented me, on several occasions for over a decade! He has been, above all an excellent lawyer to me and far superior to any other lawyer I have ever seen in the past! As a former Assistant County Prosecutor and Princeton Uni...versity. Newark etc. Prosecutor he has tons of experience. I live in North Jersey and I have to travel a bit to see him in Princeton but it is always well worth it . Mark has helped me tremendously in both the criminal matters I have had as well as the motor vehicle cases I have come to him with. He is very intelligent and really makes you feel good in Court when he is with you and you feel empowered by his sharp mind and the way he expresses himself to the court. You know that he is really going to deliver the best he can and he has for me time and time again. He doesn''t just answer the phone and give you a short answer. Rather he carefully explains things about the law and the legal system so that I understand things and he instills confidence. He cares about me and anyone who meets with Mark can clearly see that. Above all- he now only knows the law well but he knows who I am and what I want and he takes the time to do that. That impresses me . He knows how to be successful in Court and he speaks to me in a way that I feel very comfortable.Not only has he done a great job - for me every time- but he also has provided me with practical advice about my life as well as the law and how to navigate the legal system with success. The post before mine is totally absurd and out of context and whoever wrote it is ignorant, dumb and written by someone who probably has a lot more issues than just legal problems because if he knew Mark well ( as I do ) he would have known that Mark could have won his DWI case- and that this jerk wouldn't have been disappointed He must be an idiot to talk the garbage he expressed and to have gotten another lawyer- that resulted in a conviction for him! Mark has always allowed me to be successful in court for that I am indebted to him and feel it is necessary to share my feelings in this review. I have met with Mark countless times over the last ten plus years and he is a truly excellent lawyer who I always can rely on to deliver great work. He has seen me on weekends as well as after work and he is very skilled attorney who I recommend to all of my friends. He has provided me with both of his cell phones and he always picks up! He is my lawyer for life and a terrific and reliable friend. This guy is at the top of his game and you can't pick a better lawyer to help you , in my opinion! His office is open seven days a week and I have always been able to reach him when I needed- and that is priceless. Brian. - A very satisfied client and fan of Mark H. Jaffe!

mark jaffe is an " excllent lawyer "

Sitting home now, a free man, thanks to Mark Jaffe. I hired him 3 times, twice for myself, once for a motor vehicle matter, once for a criminal, municipal court matter, and once for my fiance, who had a dwi and some other very serious motor vehilce matters. She too, is home and free with me, thanks t...o Mark. Not once did he let me down or not keep his word. He is known by many, respected by all, and truly a man to know and have as a friend. Not only is he an excllent lawyer, he is a true friend, someone that really cares about you as a person, and not just as a client. Mark has become a real friend of mine, I have known Mark since May 2010, and he has " always " been 100% with me, from day 1, 100% " always ". He has never once lied to me, mislead me, or not kept his word with me, and whenever he told me something, it was true, actual fact, the results said it all. The only thing i can say is " the man is remarkable ", and his skills are unquestionable. Actions speak louder then words, and if Mark Jaffe is your lawyer, you will see a man in action, and be very pleased with the results... GO MARK, YOU THE BEST MAN, GOD BLESS YOU AND YOURS, KEEP UP THE GOOD WORK... ( on a scale of 1 to 10, i give you a 10 my brother, nothing less, your the best )

Excellent and Reliable Lawyer

Mark Jaffe is a rock solid lawyer. He truly offers an excellent service and I recommend him to anyone in need of a excellent lawyer. I've known Mark for about 5 years now and I he is my go to lawyer. I have never met a lawyer with such a great personality that delivers the kind of results he does. He... helped me get out of a DUI case and he has also helped me in much more serious matters. I honestly would recommend him to anyone. He is available 24/7 and he is always there for you when you need him.

Plainsboro Adult/Underage DWI and Reckless Driving

I am 20 years old and I had a .05 BAC reading. I was charged with a regular DWI, underage DWI, and Reckless Driving. I went straight to Mark and he told me that it would not be tough for him to fight off the adult DWI and reckless, but it would be pretty hard to prove the underage considering I told ...the officer I had a few drinks. We sent a lot of emails to each other and met weekly and he was able to get the adult DWI and reckless driving from my record so I just had to pay a small fine for the underage DWI and my insurance rates did not increase. Not only do you get your legal work done when you hire Mark, you also make a friend. When you are at his office, he gets work done and he makes a lot of side conversation so you do not get bored. He makes everything interesting for you and says a lot of random but interesting facts which makes the trip to his office worth going to.

Excellent Lawyer

Mark Jaffe represented my 16 yr. old son in a DUI matter. I was new to the criminal justice system and he explained the process and options to our family throughout the entire process. Mark was both professional and caring. He took the time to completely understand my son’s unique situation and th...en applied his experience and expertise to get a favorable outcome. Mark is an outstanding lawyer who looks at problems from multiple angles to move toward a satisfactory resolution. It is without reservation that I recommend Mark Jaffe to anyone who has to navigate through the legal system.

Professional misconduct

This lawyer was disciplined by a state licensing authority in 2022.

Suspension issued in NJ, 2022

updated on 08/22/2025

Suspension means an attorney lost his or her license to practice law for a period of time. The attorney typically returns to practicing law when the suspension expires.

Mark’s comment:

“A reprimand was issued due to a misunderstanding involving parking tickets on a friend’s vehicle I had temporarily used; although I paid my friend for the fines, procedural issues arose because I was not the registered owner, and the court held me responsible despite my good-faith effort to resolve the matter.”

Reprimanded issued in NJ, 2020

updated on 08/22/2025

This means the attorney did something wrong, but the Bar did not suspend the lawyer. Typically in this case the lawyer's poor behavior is exposed to the public in hopes that he or she will not repeat the behavior.

Mark’s comment:

“The reprimand was based solely on not having a written contract in a pro bono case, as I did not believe a formal agreement was required when offering free legal assistance.”

Censure issued in NJ, 2017

updated on 08/22/2025

This means the attorney did something wrong, but the State did not suspend the lawyer. Typically in this case, the lawyer's poor behavior is exposed to the public in hopes that he or she will not repeat the behavior.

Mark’s comment:

“While caring for my dying mother, I submitted a rushed expungement in a difficult case involving a mentally impaired client; although the outcome was successful, a complaint was later filed due to the filing’s quality, which led to a reprimand. I then provided a full refund to the client.”

Reprimanded issued in NJ, 2012

updated on 08/22/2025

This means the attorney did something wrong, but the Bar did not suspend the lawyer. Typically in this case the lawyer's poor behavior is exposed to the public in hopes that he or she will not repeat the behavior.

Mark’s comment:

“In a rare case, an interpreter—unknown to me at the time—provided false testimony, which contributed to my reprimand and mistrial; I’ve handled over 14,000 cases with integrity and success, and I remain committed to delivering strong, ethical representation.”
