The best council in New Jersey!

William Fay was there for me at every turn when I made a big mistake. He was incredibly reliable, professional, and poised. If you need a trusted and reputable attorney, he is the person. With his help, my mistake was just that and he made sure it did not jeopardize my future.

breathalyzer refusal

Will used a very technical angle from the discovery video, to negotiate a downgrade from a breathalyzer refusal to a first offense DUI in Hoboken. He is well respected in the court and very thorough. He was very accessible. He is the kind of lawyer you want to defend you.

"I endorse this lawyer. He has a firm grasp of the law in DWI matters, criminal matters, and traffic offenses. He works hard to find available defenses for his clients and to find holes in the State's case. When I was a prosecutor he represented the defendant that I was prosecuting. After much Hardwork on his end, the case against his client was ultimately dismissed."

DUI and DWI lawyer | Aug 22

Relationship: Worked together on matter

"I am an attorney who has known Will for several years and I have worked closely with him on a number of cases. I have been consistently impressed by the rare combination of professionalism, expertise, and common sense that I have witnessed from Will and his staff. I can personally vouch for his ability to always keep on top of a voluminous docket of cases, many of which are extremely complicated and emotionally draining. Regarding DUI law specifically, there seems to be a pervasive misconception that such cases are at their root fundamentally indefensible and that hiring an attorney will not ultimately help. This is far from the truth, as I have seen Will secure many favorable outcomes for clients in seemingly hopeless situations, and I myself have learned far more about DUI law from working with Will than I have from any other source. I also trust that he would not take any case unless he really believed that he could actually benefit the client. Highest possible recommendation."

His vast experience in criminal defense and DWI law - certified as both field sobriety instructor and in the operation and maintenance of the Draeger Alcotest - combined with best-in-class litigation abilities and attentiveness to clients' needs provide a true asset for anyone seeking a successful resolution for criminal charges in Superior or Municipal Court."

Avvo Rating

Our Rating is calculated using information the lawyer has included on their profile in addition to the information we collect from state bar associations and other organizations that license legal professionals. Attorneys who claim their profiles and provide Avvo with more information tend to have a higher rating than those who do not.

What determines Avvo Rating?
  • Experience & background Years licensed, work experience, education
  • Legal community recognition Peer endorsements, associations, awards
  • Legal thought leadership Publications, speaking engagements
  • Discipline Disciplinary information may not be comprehensive, or updated. We recommend that you always check a lawyer's disciplinary status with their respective state bar association before hiring them.
