Criminal Defense

Navigating the criminal justice system is a formidable task. You can rely on my experience, dedication, and advocacy when:

  • You are a witness, subject or target of an investigation by the United States, the State of New York, or the State of New Jersey
  • You have been charged with a Federal or State crime
  • You are in custody subsequent to an arrest for alleged criminal conduct
  • The eve of trial is drawing near
  • You need to appeal your conviction
  • You need to expunge your criminal record

Armed with the experience of serving as a Federal and State prosecutor in the Eastern District of New York, the District of New Jersey and Main Justice, as well as an Assistant District Attorney in the Manhattan District Attorney’s Office Trial Division and Homicide Investigations Unit, I am prepared to guide you through the entire legal process. From challenging evidence at the earliest stage, to mitigating your alleged conduct, to defending you at trial or on appeal, I will use my experience in the practice of criminal law and dedication to the people who rely on my advocacy to get you the best possible result.

Beyond the potential of incarceration and a lifelong criminal record, I understand that well after your case is over, the collateral consequences of a criminal conviction can disrupt your life for ever. Cognizant of this danger and other issues, I will not merely fight to achieve the best possible result within the law. I will work with you to implement the strategies and tactics I believe will steer you through the criminal process and place you in the best position to preserve your livelihood and career.

Although committed to my clients inside the courtroom, I advocate for clients in all matters that are related to criminal prosecution. To that end, my vast experience investigating, prosecuting and defending fraud claims allows me to diligently represent clients who are victims or witnesses to these same frauds. Whether you are a whistleblower or a victim of an embezzlement scheme, I have the knowledge, skills, and means to investigate the financial wrongdoing or fraudulent scheme. In order to best protect your interests, I can then present our findings to law enforcement to advocate for a prosecution, file suit including a monetary award, or confront the perpetrator so that they will cease the damaging conduct.

Whether you are facing an investigation, arrest or trial involving the United States Attorney’s Office, FBI, Secret Service or other Federal agency; are confronted with the same from the New York Police Department, New York State Attorney General, or local New York District Attorney; or are involved in a matter with the New Jersey State Attorney General, or New Jersey County Prosecutor’s Office, you need to take the steps necessary to protect yourself.

Similarly, if you are a victim of a crime or you are aware of fraudulent conduct by your employer or otherwise, you need not sit idly by and remain silent. Put yourself in the right place and set your defense or case into motion. Contact the Law Offices of Peter Katz and allow my experience, dedication and advocacy work for you.

With this in mind, the Law Offices of Peter Katz represents defendants, targets and witnesses in a vast array of criminal cases in Federal and State Court in New York, New Jersey and throughout the Country. I am the Manhattan Criminal Defense Lawyer and New Jersey Criminal Attorney you can count on.
