What to Expect in a Federal Money Laundering Defense Prosecution

July 2026 · 6 min read · John D. Kirby, Former Federal Prosecutor

A federal money laundering prosecution under 18 U.S.C. § 1956 can be one of the most challenging and complex legal battles a defendant will face. The path from indictment to sentencing is fraught with technical legal issues, stringent procedural requirements, and significant potential penalties. Understanding what lies ahead is crucial for defendants seeking to mount an effective defense.

The process begins with the filing of an indictment by a federal grand jury. This document formally charges the accused with violating 18 U.S.C. § 1956 or related statutes such as structuring (18 U.S.C. § 1956(i)) and bulk cash smuggling (31 U.S.C. §§ 5342, 5330). The indictment sets out the specific charges based on allegations of knowing participation in financial transactions involving proceeds from a specified unlawful activity, knowledge that funds were derived from illegal activities, or attempts to evade reporting requirements.

Following the return of an indictment, defendants must appear before a federal magistrate judge for arraignment. During this brief hearing, the defendant is informed of the charges and formally enters a plea. The defense counsel will work diligently to ensure that all procedural requirements are met and that their client’s constitutional rights are protected during this critical stage.

The discovery phase follows shortly after arraignment. This process involves both the government and the defense exchanging information, including evidence collected by law enforcement and other documents pertinent to the case. Effective counsel will use this period not only to gather essential information but also to begin building a strategic defense based on the evidence at hand.

Pretrial motions are another critical component of the process. Counsel may file various motions challenging the legality of searches, seizures, or wiretaps conducted by investigators. Additionally, defendants can seek to suppress evidence obtained in violation of their constitutional rights through motions to suppress. The success of these motions can significantly impact the strength and viability of the prosecution’s case.

Plea negotiations often occur concurrently with pretrial proceedings. In many cases, prosecutors are willing to offer plea agreements that may reduce charges or sentencing exposure if defendants agree to plead guilty rather than go to trial. Experienced counsel will work closely with their clients to weigh the pros and cons of accepting a plea deal versus proceeding to trial.

If the case proceeds to trial, it can be an intensive process involving jury selection, opening statements, presentation of evidence by both sides, cross-examination of witnesses, and closing arguments. The defense team will work tirelessly to present a robust case that casts doubt on the government’s accusations or undermines its proof beyond a reasonable doubt.

Post-trial options include motions for acquittal or new trial if the jury returns a guilty verdict. Additionally, defendants have the right to appeal their conviction or sentence through higher courts, challenging legal rulings made by the lower court judge or aspects of the trial process. ← Back to Practice Area
