How a Criminal Defense Attorney Can Help in Federal White Collar Investigations

If you’ve received a subpoena, a target letter, or a knock at your door from a federal agent, you may be under investigation for a white collar crime. These cases are typically handled by federal agencies such as the FBI, IRS, U.S. Postal Inspection Service, or Department of Justice, and they involve serious allegations like fraud, embezzlement, bribery, or conspiracy.

Even if you haven’t been formally charged yet, early legal representation is critical. A skilled criminal defense attorney can often shape the investigation’s direction, protect your rights, and—in some cases—prevent charges altogether.

Here’s how a federal white collar defense lawyer like Mark D. Hauser can help if you’re being investigated in Philadelphia or anywhere in Pennsylvania.

What Are White Collar Crimes?

White collar crimes are non-violent offenses that usually involve deception, dishonesty, or financial gain. Common examples include:

  • Wire fraud or mail fraud

  • Tax fraud or tax evasion

  • Embezzlement or misappropriation of funds

  • Health care fraud

  • PPP loan fraud or COVID-related relief fraud

  • Insider trading or securities fraud

  • Money laundering

  • Bank fraud or mortgage fraud

  • Bribery or public corruption

Federal prosecutors take these cases very seriously, and conviction can lead to years in prison, severe fines, and reputational ruin.

Early Stages of a Federal Investigation

If you are a target, subject, or even a witness, the government may:

  • Issue a grand jury subpoena for documents or testimony

  • Send a target letter informing you that you may be charged

  • Execute a search warrant at your home or business

  • Request a voluntary interview

At this stage, you may not know how much evidence they have—or what their intentions are. That’s why hiring a defense attorney early can make a critical difference.

How a Criminal Defense Lawyer Can Help

1. Protect Your Rights Immediately

A federal defense attorney will:

  • Communicate with investigators on your behalf

  • Ensure you don’t say anything self-incriminating

  • Help you respond to subpoenas or search warrants lawfully

  • Prevent mistakes that could lead to obstruction charges

Without legal guidance, you may unintentionally provide information that strengthens the government’s case.

2. Assess the Government’s Evidence

Your lawyer can help you understand:

  • Whether you are a witness, subject, or target

  • What laws you may have violated (or are accused of violating)

  • How strong the government’s case appears to be

  • Whether early cooperation makes sense—or not

This insight allows you to make informed decisions about your next steps.

3. Negotiate Before Charges Are Filed

In many federal cases, your attorney can communicate directly with the U.S. Attorney’s Office and negotiate:

  • A non-prosecution agreement

  • A deferred prosecution

  • A reduction in potential charges

  • A proffer agreement (if cooperation is beneficial)

These conversations are strategic and must be handled carefully—only an experienced attorney should negotiate on your behalf.

4. Build a Strong Defense if Charges Are Filed

If charges are brought, a federal defense attorney can:

  • Challenge the indictment

  • Review and suppress unlawfully obtained evidence

  • Hire forensic accountants or investigators

  • Prepare for trial or negotiate a favorable plea deal

Federal prosecutors have extensive resources. You need a defense that’s equally prepared and strategic.

5. Manage the Public and Professional Impact

White collar accusations can damage your career, finances, and personal reputation. Your attorney can:

  • Coordinate a discreet legal response

  • Help manage communications with employers or licensing boards

  • Explore strategies for minimizing collateral consequences

Don’t Wait for Formal Charges

By the time you’re contacted by federal authorities, they’ve already done months—or even years—of investigation. The earlier you involve legal counsel, the better your chances of avoiding the worst-case scenario.
