Criminal Investigation Defense Attorney

in Fort Lauderdale, Florida
By the time you are charged, the government’s case is already built. Evidence gathered. Witnesses interviewed.
A narrative locked in place. From that moment forward, your defense is reactive, responding to what they have already assembled against you, on a timeline they control.

The most powerful position you can be in is the one most people never think to take: represented before charges are ever filed.

At Mayersohn Law Group, we represent clients who are under investigation before the knock on the door ever comes.

We bring deep experience in financial crimes, regulatory matters, and complex criminal defense to bear at the earliest and most critical stage of the process, when there is still the most to fight for.

We know where these cases come from, how they were assembled, and where they can be challenged.

What Happens If You Wait

In federal and state investigations, waiting is rarely neutral. Every day without experienced legal counsel is a day the government’s case continues to develop unchallenged.
Here is what that delay can cost you:
  • By the time law enforcement contacts you, investigators may have already spent months or years building a case
  • Statements made to federal agents, even apparently innocent ones, can be used against you
  • Critical early decisions made without counsel can permanently limit your defense options
  • Target status can change without warning, subjects become targets, witnesses become subjects
  • Parallel civil, regulatory, and criminal proceedings can unfold simultaneously, each affecting the others
  • Careers, licenses, businesses, and reputations are often damaged long before a case reaches court

Types of Investigations We Handle

Federal criminal cases operate in an entirely different environment from state court, and the stakes are exponentially higher.

Corporate Criminal Investigations

Corporate investigations can arise from whistleblower complaints, regulatory referrals, competitor complaints, or law enforcement discovery during an unrelated matter. They may target the corporation, individual executives, or both, and parallel civil, regulatory, and criminal proceedings often unfold at the same time. The decisions made in the first days determine the outcome for the company and everyone involved, including whether and how to cooperate, how to conduct internal investigations without waiving privilege, and how to protect executives with separate exposure.

These calls cannot be made without experienced counsel in place.

SEC and CFTC Investigations

The SEC and CFTC investigate potential violations of federal securities and commodities laws, and both agencies can refer matters to the DOJ for criminal prosecution.

Common areas of investigation include:

  • Insider trading and market manipulation
  • Ponzi schemes and unregistered securities offerings
  • False statements in public filings
  • Fraud and manipulation in commodity futures, options, and swaps markets
  • Digital assets and cryptocurrency violations

A critical milestone in SEC matters is the Wells Notice, a formal notification that enforcement action is being recommended. Your Wells submission is one of the most consequential documents in a securities enforcement matter. Getting it right can result in charges being reduced or dropped. Getting it wrong can make things significantly worse.

OIG Investigations

Every major federal agency has its own Office of Inspector General.

OIG investigations are particularly common in:

  • Healthcare fraud including Medicare and Medicaid false claims and kickbacks
  • Government contracting involving false claims or bid rigging
  • Federal program fraud including benefits and grant fraud
  • Federal employee misconduct and abuse of office

OIG investigations can result in criminal referrals to the DOJ, civil False Claims Act liability, and administrative consequences including exclusion from federal programs, which can be career-ending for healthcare providers and federal contractors. The False Claims Act carries treble damages plus civil penalties per false claim, on top of criminal prosecution risk.

Florida Criminal Investigation Defense Attorneys Who Act Before Charges Are Filed

By the time law enforcement contacts you, serves a subpoena, requests an interview, or executes a search warrant, prosecutors may have already spent weeks, months, or years gathering evidence.

What you do next, and how quickly you involve experienced legal counsel, can significantly affect the outcome. Our firm represents professionals, executives, business owners, healthcare providers, and financial professionals throughout Broward, Miami-Dade, Palm Beach, and across Florida facing state and federal criminal investigations.

We understand that investigations often threaten careers, licenses, reputations, and financial stability long before a case ever reaches court. Early intervention matters, and we are ready to move from day one.

Frequently Asked Questions About Investigations in Florida

VIEW ALL FAQs

What are signs that I may be under investigation?

Common signs include contact from law enforcement, subpoenas, search warrants, requests for interviews, inquiries involving financial records, visits to coworkers or family members, or learning that others connected to you are being questioned.

What should I do if federal agents contact me?

Politely decline to answer questions without your attorney present. You have the right to remain silent regardless of whether you are a target, subject, or witness. Statements made to federal agents, even apparently innocent ones, can have serious consequences. Contact us immediately.

Should I speak to investigators if I have done nothing wrong?

In most situations, no. Even innocent statements can be misinterpreted or used against you. Investigators are trained to gather information that supports their case, and speaking without an attorney present creates unnecessary risk regardless of your actual innocence.

What is a Wells Notice and what should I do if I receive one?

A Wells Notice is a notification from SEC staff that they intend to recommend enforcement action against you. It triggers the right to submit a Wells response, a written submission explaining why enforcement action is unwarranted. This is one of the most critical documents in a securities enforcement matter and requires immediate, experienced legal attention.

What is an OIG investigation and can it lead to criminal charges?

OIG investigations target fraud, waste, and misconduct in federal programs. They can and frequently do result in criminal referrals to the DOJ, civil False Claims Act liability, and administrative consequences including exclusion from federal healthcare programs. If you are contacted by any OIG or believe an OIG investigation may involve you, contact an attorney before responding.

What is a subpoena and can I ignore it?

A subpoena is a legal demand requiring a person to provide testimony, records, or other evidence. Subpoenas cannot be ignored, and responding improperly can create additional legal exposure. Contact an attorney before taking any action in response to a subpoena.

Can an internal corporate investigation protect me as an individual?

Not automatically. Internal investigations conducted by company lawyers represent the company, not individual employees. Employees who participate without their own counsel may make statements that harm their personal legal interests. Individuals under investigation should have independent counsel separate from the company’s attorneys.

What is the difference between a target, subject, and witness in a federal investigation?

A target is someone the government already has substantial evidence against and expects to charge. A subject is someone whose conduct falls within the scope of the investigation but who has not yet been identified as a likely defendant. A witness has no current criminal exposure but can become a subject or target as the investigation develops. All three statuses carry risk, and all three warrant legal representation.

Criminal Investigation Defense Across Fort Lauderdale, Broward County, and Florida

Many people assume they should wait until they are formally arrested or charged before hiring a criminal defense attorney.
In reality, some of the most critical decisions in a criminal case happen during the investigation itself, when prosecutors are still gathering evidence, interviewing witnesses, and determining whether charges will be filed.

Mayersohn Law Group represents clients throughout Broward County, Miami-Dade County, Palm Beach County, and across Florida facing state and federal investigations involving fraud, white collar crimes, financial offenses, healthcare matters, professional licensing exposure, and other high-stakes cases.

If you have been contacted by law enforcement, received a subpoena or target letter, or believe you may be under investigation, contact Mayersohn Law Group today to schedule a confidential consultation.
