New York City Severance Motion Lawyer

A severance motion asks the court to separate what the government has bundled together, whether that means splitting multiple defendants into separate trials, breaking apart distinct charges that were joined in a single indictment, or both. It is one of the most consequential pretrial tools available to a criminal defendant in New York, and yet it is consistently underused, misunderstood, or raised too late. When the prosecution charges five people in one indictment and plans to put all of them in front of the same jury, every word of testimony about co-defendant A lands in the ears of jurors who are also deciding the fate of defendant B. The arithmetic of that arrangement almost always favors the government. A well-timed, well-argued New York City severance motion lawyer can dismantle that advantage before the first juror is seated.

Federal and state courts in New York handle severance under distinct procedural frameworks. In federal court, Rules 8 and 14 of the Federal Rules of Criminal Procedure govern joinder and severance. In New York state court, Criminal Procedure Law sections covering consolidation and joinder control the analysis. The legal standards differ, but the underlying strategic logic is the same: the right to a fair trial means the right not to be condemned by guilt absorbed from others. Courts are not always quick to grant severance, which is precisely why the written motion, the supporting record, and the timing of the request matter so much. Getting there requires specific legal knowledge and disciplined preparation, not a boilerplate brief filed the week before trial.

For defendants facing multi-count indictments or co-defendant prosecutions in Manhattan’s Southern District, Brooklyn’s Eastern District, or state courts throughout the five boroughs, the question of whether to pursue severance can define the entire trajectory of the case. The decision involves weighing the realistic probability of success, the evidentiary landscape at the time of filing, and the way the motion interacts with every other pretrial move being made simultaneously. That calculus requires counsel who understands both the law and the particular prosecutorial culture of the court where the case is pending.

What Severance Motions Actually Cover in New York Criminal Cases

• Misjoinder of Defendants: When multiple defendants are charged together solely because the government finds a consolidated trial more efficient, rather than because their conduct is genuinely connected, a defendant may argue that initial joinder was improper under the applicable rules, making severance the correct remedy even before prejudice analysis begins.
• Prejudicial Spillover from Co-Defendant Evidence: Much of the government’s evidence in a multi-defendant case may be admissible only against certain defendants. Jury instructions telling jurors to mentally compartmentalize that evidence are difficult to follow in practice, and courts in the Second Circuit have acknowledged that limitation in granting severances where the risk of spillover was substantial.
• Antagonistic Defenses: When one co-defendant’s best defense is to point the finger at another co-defendant, a joint trial forces both defendants into an impossible position. New York and federal courts have found that mutually antagonistic defenses can rise to the level of compelling prejudice sufficient to warrant severance, particularly where the competing defenses cannot both be presented without one undermining the other.
• Bruton Problems and Confrontation Clause Issues: Under Bruton v. United States, a non-testifying co-defendant’s out-of-court confession that incriminates another defendant cannot constitutionally be admitted at a joint trial unless the statement is redacted in a way that eliminates all references to the other defendant. Courts have sometimes been satisfied with redactions; other times they have not. Where the confession is too central to be meaningfully redacted, severance may be the only constitutionally adequate remedy.
• Disparity of Evidence: When the government’s proof against one defendant is overwhelming and its proof against another is thin, a joint trial risks having the jury transfer the weight of one case onto the other. This disparity argument is harder to win on its own but can be powerful when combined with other grounds.
• Severance of Counts Within a Single Indictment: Severance is not only about separating defendants. A defendant charged with, for example, a drug offense and an unrelated assault in the same indictment may seek to have those counts tried separately, arguing that trying them together invites the jury to treat the combination as character evidence of a criminal type rather than evaluating each charge independently.
• Complex Multi-Defendant Conspiracies: In large federal drug or racketeering prosecutions, the sheer volume of evidence introduced against some defendants may overwhelm a jury’s ability to meaningfully apply it only to the defendant for whom it is actually relevant. Courts have recognized that extreme complexity can independently justify severance even where joinder was technically proper.

Why the Law Offices of Jason Goldman Handles These Motions Differently

Severance motions are, at their core, persuasion problems. The law often gives a judge discretion to grant or deny, which means the quality of the argument, the precision of the record citations, and the advocate’s credibility with the court all factor into the outcome in ways that go beyond the text of the motion itself. Jason Goldman built his practice on understanding that distinction. A former Brooklyn prosecutor who rose quickly through the ranks trying serious felony cases, he moved into private defense work carrying the same litigation instincts he developed on the other side of the courtroom. He has since tried more than 25 cases to verdict and has developed a practice spanning pre-arrest investigations, trial, sentencing, and appellate work across state and federal courts in New York.

That prosecutorial background is particularly relevant for severance work. Goldman understands how the government thinks about joinder, what it is hoping to accomplish strategically by trying defendants together, and where the internal logic of a multi-defendant case is weakest. Named a New York Super Lawyers Rising Star and quoted in publications including the New York Post and recognized by national media as a high-profile defense attorney, Goldman is known for the kind of meticulous case preparation that severance motions demand. The motion itself must be grounded in a developed factual record, anticipate the government’s counterarguments, and be timed to land before the court has locked itself into a procedural posture that makes reversal less likely. Goldman approaches severance not as an isolated filing but as a piece of the broader pretrial narrative that shapes how the judge sees the defendant long before trial begins.

Building and Filing a Severance Motion in New York State and Federal Court

Timing is the variable most often mishandled in severance practice. In New York state court, pretrial motions including severance motions are typically governed by scheduling orders issued at arraignment or shortly after. Missing the deadline without good cause can result in waiver of the argument. In federal court, severance motions must generally be filed within the time set by the district court’s scheduling order, and the judge has broad discretion to deny late-filed motions regardless of their underlying merit. The moment a defendant is arraigned on a multi-count or multi-defendant indictment, the clock on the severance question starts running.

The first practical step after arraignment is a thorough review of the indictment itself. Which counts are joined, and on what theory? Which co-defendants are named, and what is the alleged connection between their conduct and your client’s? Has the government disclosed any co-defendant confessions or statements? Are there any early signals of antagonistic defenses? These questions need answers before counsel can intelligently assess whether severance is worth pursuing and, if so, on which grounds. The indictment alone may not tell the full story; early discovery requests are often essential to fleshing out the evidentiary picture before the motion deadline arrives.

In Manhattan, state felony cases are handled at New York County Supreme Court, located at 100 Centre Street. Federal cases in the borough flow through the United States District Court for the Southern District of New York at 500 Pearl Street. In Brooklyn, state cases are handled at Kings County Supreme Court and federal cases at the Eastern District courthouse at 225 Cadman Plaza East. The procedural culture of each courtroom matters. Judges in the Southern District handle a high volume of complex white-collar and narcotics conspiracies and are experienced with severance arguments in those contexts. State court judges in the five boroughs vary considerably in their receptivity to these motions, and knowing which arguments land with which judicial temperaments is part of the practical knowledge that informs how to frame the motion.

One mistake defendants sometimes make is waiting to see whether the government’s case develops in a way that makes severance more obvious before filing. That approach backfires for two reasons. First, it risks waiver. Second, it surrenders the opportunity to shape the court’s pretrial thinking early, before the judge has mentally committed to a joint trial framework. Raising severance proactively, with a well-developed record, signals to the court that the defendant is not merely delay-seeking but is raising a genuine constitutional and procedural concern that deserves careful attention.

Questions About Severance Motions in New York

What is the standard a court uses to decide whether to grant a severance motion?

Courts look at whether joinder of defendants or counts will cause actual, substantial prejudice to the moving defendant that cannot be cured by jury instructions. The threshold is not merely that joinder is inconvenient or that the defendant would prefer a separate trial. The court asks whether the prejudice from being tried together is so significant that the defendant cannot receive a fair trial without separation. In federal court, Rule 14 of the Federal Rules of Criminal Procedure provides the framework for this analysis. In New York state court, the analysis is similar but governed by the Criminal Procedure Law’s consolidation and severance provisions.

When should a severance motion be filed in a New York federal case?

Federal district courts in New York typically set pretrial motion deadlines in their scheduling orders issued early in the case. In the Southern and Eastern Districts, these deadlines are taken seriously. Filing after the deadline requires showing cause for the late filing, and many judges will not entertain untimely motions on the merits. As a practical matter, the evaluation of whether to file a severance motion should begin at or shortly after arraignment, well before any deadline is in sight.

Can a severance motion be renewed at trial even if it was denied pretrial?

Yes. Even if a court denies a pretrial severance motion, the defendant typically can renew the motion as the trial develops, particularly if new information emerges during the proceedings that supports the original prejudice argument more concretely. An appellate record on severance is stronger when the issue has been raised both pretrial and, where appropriate, renewed at trial. The renewal also preserves the argument more cleanly for any subsequent appeal.

How does a Bruton problem actually arise in a joint trial, and what can the defense do about it?

A Bruton problem arises when the government wants to introduce a statement made by a co-defendant who is not going to testify at trial, and that statement implicates the other defendant by name or by clear implication. The Confrontation Clause prohibits using such a statement against the non-declarant defendant because that defendant has no opportunity to cross-examine the person who made the statement. Courts sometimes resolve this by ordering redaction of the statement. Where redaction would be inadequate because the statement is too central to the government’s case or too obvious in context, the defense can argue that severance is the only constitutionally sufficient remedy. Identifying a Bruton problem early, before the court has designed its trial management approach around the government’s evidence, is essential.

Is it harder to win a severance motion in a high-profile conspiracy case?

Courts have been reluctant to sever large conspiracy cases simply because the case is complex or because some defendants face more serious evidence than others. However, complexity and disparity of evidence do factor into the analysis, and they can strengthen a severance argument when combined with more targeted grounds like Bruton issues or antagonistic defenses. In high-profile federal prosecutions in the Southern District, defense counsel must be prepared for a court that has significant experience managing large multi-defendant cases and that may be skeptical of severance arguments made without a specific, concrete showing of prejudice.

If my severance motion is denied, does that mean I have no appellate recourse on this issue?

A denial of a severance motion is reviewed on appeal for abuse of discretion, which is a deferential standard. However, an appellate court can and does reverse on severance grounds when the trial record demonstrates actual, substantial prejudice that the district court’s ruling failed to address. Preserving the issue correctly at trial, and building the record during trial that demonstrates how the prejudice actually materialized, is essential to having any realistic shot at appellate relief on this ground. The pretrial motion alone is rarely enough; the trial record needs to support the argument as well.

Can a co-defendant’s guilty plea affect a pending severance motion?

Yes, and significantly. If a co-defendant pleads guilty before trial, the dynamics of the joint proceeding change substantially. The remaining co-defendants may no longer face the same Bruton risk, and the evidence landscape shifts. A guilty plea by one co-defendant can sometimes moot a severance argument entirely, or it can strengthen one if the pleading co-defendant is expected to testify as a government cooperator, creating new confrontation dynamics among the remaining defendants. Counsel needs to reassess the severance posture each time a co-defendant’s status changes.

What happens if two co-defendants want to blame each other at trial?

This is the classic antagonistic defenses scenario. When Co-defendant A’s best trial strategy is to argue that Co-defendant B was actually responsible, and Co-defendant B’s best strategy is the mirror image, a joint trial can effectively destroy both defenses simultaneously. Courts have recognized that mutually antagonistic defenses, where acceptance of one defense necessarily requires rejection of the other, can constitute a sufficient basis for severance. The key is demonstrating to the court that the defenses are genuinely irreconcilable, not merely different, and that the jury cannot fairly evaluate both without each undermining the other.

Does the size of the indictment, meaning the number of counts, strengthen a severance argument for counts?

Not automatically. The question is not how many counts are in the indictment but whether trying them together creates a specific prejudice that cannot be cured. That said, a voluminous indictment with counts that are factually distinct and temporally remote from each other may provide a stronger foundation for arguing that a jury cannot realistically compartmentalize the evidence for each count. In practice, the more the additional counts look like character evidence of general criminality rather than proof of a connected scheme, the stronger the argument for trying them separately.

How does a severance motion interact with the overall defense strategy at trial?

Severance motions do not exist in isolation. The decision to move for severance, and how aggressively to pursue it, needs to be evaluated alongside the overall defense theory. In some cases, a joint trial is actually strategic for a particular defendant because it allows counsel to contrast a client favorably against co-defendants who present worse. In other cases, the joint trial is clearly harmful and must be attacked. The analysis requires understanding not only the law but the specific evidentiary and narrative dynamics of the case, including what the government’s witnesses are expected to say, what co-defendant counsel is likely to argue, and how the jury is likely to process all of it together.
