A federal proffer session is a voluntary meeting where a person under investigation sits down with the assigned Assistant United States Attorney and federal agents to share information under a written agreement. It is not a plea deal, not a grant of immunity, and not an admission of guilt.
Proffers arise frequently in Houston-area investigations involving wire fraud, drug conspiracy, healthcare fraud, and money laundering. Before agreeing to one, you need to understand exactly what the written agreement protects, what it does not, and whether participating actually serves your interests.
How Our Federal Defense Team Prepares You for a Proffer
At the John T. Floyd Law Firm, our federal defense attorneys review all available discovery and assess your full exposure before any meeting takes place. We negotiate agreement terms in advance to limit the government’s ability to act on derivative information and push for the strongest protections the AUSA will accept.
Our team conducts mock preparation sessions so you understand what federal prosecutors ask and know which topics to avoid. Our attorney will be present throughout, but cannot answer questions on your behalf. After the session, we give you a clear-eyed assessment of whether to pursue a formal cooperation agreement or take your case to trial.
What the Proffer Agreement Actually Covers
The written proffer agreement prevents the government from using your statements directly as evidence against you at trial. This is not the same as statutory immunity under 18 U.S.C. § 6002, which requires a court order and carries broader protections.
Critically, even if prosecutors cannot use your exact words at trial, they can still use what you told them to find new witnesses, pull new records, or build entirely new evidence against you. This is called derivative use, and your agreement may or may not limit how far they can go with it. Agreement terms vary significantly between jurisdictions and individual prosecutors, which is why our attorneys review and negotiate those terms before you sign.
Sentencing Benefits Require a Government Motion
If cooperation leads to charges being filed, a defendant who provided substantial assistance may benefit from a downward departure under USSG § 5K1.1, which allows the court to impose a sentence below the applicable guideline range. The government must file this motion (the court cannot grant it on its own), and prosecutors have broad discretion over whether to do so even when a defendant has cooperated fully.
Important: if your charge carries a mandatory minimum sentence, a fixed floor that the judge cannot go below on their own, a 5K1.1 motion alone is not enough. The government must also file a separate motion under 18 U.S.C. § 3553(e) to allow the judge to go below that floor. Not all cooperation agreements include this, and many drug trafficking and healthcare fraud cases carry mandatory minimums. This is something to confirm with your attorney before you agree to cooperate.
Early cooperation before indictment can also lead to deferred prosecution agreements or a decision not to charge at all, both of which are significantly harder to achieve after an indictment is filed.
Criminal Exposure for False Statements During a Proffer
Lying during a proffer session carries serious federal consequences. Making false statements to federal agents violates 18 U.S.C. § 1001, which carries up to five years in federal prison, increasing to eight years when the offense involves terrorism or certain sex crimes. Prosecutors can also pursue obstruction of justice charges under 18 U.S.C. § 1503.
Beyond criminal exposure, if your proffer statements conflict with later trial testimony, prosecutors will use those inconsistencies against you before a jury. Defendants who enter proffer sessions unprepared frequently give the government evidence it did not previously have.
Situations Where Declining a Proffer Is the Right Decision
A proffer is not appropriate in every case. Declining may be the stronger position when:
- The government’s evidence is weak without your cooperation
- Your defense attorney has identified strong suppression arguments
- Co-defendant dynamics make participation unpredictable
- The written agreement does not adequately limit derivative use
- An independent investigation has produced evidence favorable to the defense
The decision to proffer should never be made under pressure or without a thorough assessment of the government’s existing evidence.
