Improper joinder of defendants: what to do, step by step

TL;DRImproper joinder of defendants is a procedural defect that runs through a significant share of "Schedule A" IP enforcement cases filed in US federal court against marketplace sellers. When a plaintiff bundles dozens – sometimes hundreds – of unrelated sellers into a single complaint to secure one asset-freezing order, each seller named becomes a Schedule A defendant even though their accounts have no real legal connection to the others. The defect matters because it can be the most efficient path to dissolving or narrowing the temporary restraining order that froze your funds before you knew the case existed.

This guide walks through what improper joinder of defendants actually means in the Schedule A context, how to move on it procedurally, where sellers stall, and the trade-offs at each decision point. It is written for sellers who have just discovered a frozen Amazon account, PayPal balance, or third-party payment hold tied to a federal court action – and who want to understand the realistic options before deciding how to respond.

What is improper joinder of defendants in a Schedule A case?

Improper joinder is a doctrine under the Federal Rules of Civil Procedure that limits which defendants may be combined in a single lawsuit. To join multiple defendants, the plaintiff must allege that the claims against them arise out of the same transaction, occurrence, or series of transactions, and that common questions of law or fact will arise. In practice, Schedule A complaints routinely fail both prongs.

A plaintiff filing a "SAD scheme" case will attach a sealed exhibit – the Schedule A – listing anywhere from a handful to several hundred individual seller accounts. Each account typically belongs to a different entity, operating independently, selling its own inventory, with no shared ownership, no common supply chain, and no coordination whatsoever with the other defendants. The only thread connecting them is that the plaintiff has accused each of selling allegedly infringing goods on the same marketplace. Courts have increasingly recognized that this thread is not enough.

The commercial consequence is significant. Every seller named in the Schedule A shares a single TRO. That order typically directs Amazon, PayPal, and any other identified payment processor to freeze each defendant's accounts simultaneously. A seller with a completely independent business – perhaps a small FBA operation with no knowledge of the other defendants – wakes up to a frozen balance and suspended disbursements because they were swept into a mass filing alongside strangers. In matters we handle, the freeze often hits before the seller has been served or has any idea litigation has started.

Misjoinder is therefore not a technicality. It is the structural flaw in the case that, when successfully raised, can support a motion to sever the seller from the action – and, critically, to dissolve or modify the TRO as it applies to that seller's accounts.

Step 1 – Identify what you are actually dealing with before anything else

The first step is to confirm that the freeze is tied to a Schedule A federal complaint and not to a separate Amazon enforcement action or payment-processor hold. The two look similar from inside Seller Central but require completely different responses.

If Amazon has sent a disbursement-hold notice that references a court order, look for the name of a federal district court – most often the Northern District of Illinois or the Southern District of New York – and a case number. That case number is your entry point to the federal court's public docket, which will typically show the complaint and, if the seal has been partially lifted, the schedule. For a detailed overview of how sealed filings work and how defendants locate their own case, see a seller's path through a sealed complaint against online stores.

Once you have confirmed the case is a Schedule A action, identify the plaintiff's IP rights at issue, the specific claims (trademark infringement, copyright, patent), and whether the TRO includes an asset-freeze order directed at third-party payment processors. Note whether you have been served. Service in these cases is often by email or through the marketplace platform's registered agent – and many sellers have missed the deadline to respond because they did not realize that notice to Amazon counted as notice to them.

Where this step goes wrong: sellers who assume the hold is an Amazon-internal policy action spend critical days sending appeals through Seller Central when they should be engaging with the federal proceeding. The two tracks are entirely separate. Nothing you file in Seller Central stops a federal court order.

Step 2 – Get the complaint and analyze the joinder allegations

A Schedule A complaint is a pleading, and like any pleading it must satisfy the joinder rules. The question at this step is whether the plaintiff has actually alleged – in the complaint itself – facts sufficient to satisfy the "same transaction or occurrence" requirement as to each defendant, including you.

In the cases we review, the typical Schedule A complaint contains boilerplate allegations that all defendants are part of a "common course of conduct." Courts have split on whether that kind of group pleading satisfies the joinder standard. A growing number of judges in the most common filing districts have expressed skepticism and, in some instances, have sua sponte raised the joinder issue themselves. That judicial trend is one of the most useful developments in Schedule A defense work over recent years.

Analyzing the complaint means checking four things. First, what specific facts, if any, tie your store to any other defendant? Second, does the complaint allege actual coordination, shared supply chains, or common source of allegedly infringing goods – or does it rely solely on the fact that multiple sellers listed the same or similar products on the same platform? Third, are the accused products genuinely identical across defendants, or does the schedule include a range of products that share only a broad category? Fourth, is there any exhibit or evidence attached to the TRO application that connects your specific account to any other defendant's conduct?

If the honest answer to the first three questions is "nothing beyond selling on the same platform," you likely have a viable misjoinder argument. For context on how de-anonymization and the schedule's composition affect a seller's strategic options, see why de-anonymizing a Schedule A complaint happens and how sellers respond.

Step 3 – Move to dissolve or modify the TRO, and to sever

The procedural vehicle for raising improper joinder is a motion to sever, typically combined with a motion to dissolve or modify the TRO as it applies to your account. These are two distinct motions that often travel together because winning severance without addressing the TRO leaves your funds frozen while the severed case continues.

The motion to sever argues that joinder was improper from the outset: the plaintiff cannot satisfy Rule 20(a)(2) of the Federal Rules of Civil Procedure, and each defendant's case should proceed independently. The motion to dissolve or modify the TRO argues that, in light of the improper joinder, the ex parte showing that justified a single order covering all defendants was defective, and that the asset freeze as it applies to your accounts should be lifted or narrowed.

Courts typically schedule a hearing on TRO modification within days to weeks of a motion being filed – the timeline is driven by the preliminary injunction deadline that flows from the initial TRO. That deadline matters. If the plaintiff does not convert the TRO to a preliminary injunction within the period set by the court, the TRO dissolves by operation of law. A well-timed severance motion can accelerate that outcome for a misjoined defendant.

What to include in the motion: a precise account of your seller's relationship (or absence of relationship) to any other defendant; evidence that your store operates independently; a concise legal argument on the Rule 20 standard; and, if possible, a comparison of the complaint's joinder allegations against the actual facts in the schedule. Where this goes wrong: sellers who file a motion that reads like an Amazon appeal letter – narrative, apologetic, policy-focused – rather than a litigation brief. Federal motions practice has a specific form and a specific standard. The judge is not reading a Plan of Action.

Step 4 – Handle jurisdiction and personal jurisdiction challenges in parallel

Improper joinder and personal jurisdiction are distinct defenses, but they often arise together in Schedule A cases. Many sellers named in these actions have no meaningful contact with the state where the case was filed. An FBA seller based in California or Texas, operating under a Delaware LLC, selling to customers across the US, is unlikely to have purposefully directed activity at Illinois specifically – yet a significant share of Schedule A filings are concentrated in the Northern District of Illinois.

Personal jurisdiction challenges must be raised early. Under federal procedure, failure to raise a personal jurisdiction defense in the first responsive pleading or pre-answer motion results in waiver. If you are raising a misjoinder motion and you also have a personal jurisdiction argument, both need to be in front of the court at the same time – typically in a single motion or in motions filed simultaneously.

The practical effect of a successful personal jurisdiction challenge is dismissal of the claims against you – a stronger result than severance alone, which leaves the case pending against you in a different posture. In matters we handle, we review both grounds in the initial analysis because the combination of arguments, even where one is stronger than the other, tends to put the plaintiff in a more difficult position and often creates room for a more favorable settlement.

Where this step goes wrong: sellers focus on the joinder argument because it feels more intuitive – "I don't belong in this lawsuit with these other people" – and miss the jurisdictional challenge that might end the case entirely. Waiving personal jurisdiction by omission is one of the costlier procedural mistakes in Schedule A defense.

Step 5 – Evaluate settlement in parallel with litigation strategy

Raising improper joinder and a TRO dissolution motion does not mean the case will be litigated to a verdict. In practice, most Schedule A cases that do not settle early end in default judgment against defendants who never appeared – and most defendants who do appear resolve the case before trial. The question is not whether to consider settlement but when and on what terms.

A well-briefed severance motion changes the settlement dynamic. The plaintiff now faces the prospect of litigating against you separately, in a case that cannot rely on the compressed TRO schedule, with a defendant who has appeared and is raising substantive defenses. For plaintiffs whose goal is primarily to get infringing listings removed and collect a standard license fee, a seller who is actively contesting the case is a different negotiation than a seller who defaulted. That is the leverage a properly filed motion creates.

Settlement in this context typically involves a consent order, a license or covenant not to sue, and payment of some sum. The realistic range of outcomes depends on the underlying IP claim, the volume of allegedly infringing sales the plaintiff can document, whether your products were actually infringing, and the plaintiff's litigation posture. We do not promise particular terms, but we do make sure that the negotiation happens from the right position.

An electronics FBA seller on Amazon US (winter 2025) came to us after discovering a TRO-driven asset freeze tied to a Schedule A trademark complaint filed in the Northern District of Illinois. The complaint named more than eighty defendants, with no allegation connecting the seller's account to any of the others beyond listing a product in the same broad category. We filed a combined motion to sever and to dissolve the TRO, identifying the absence of any same-transaction allegation and the seller's lack of contacts with Illinois. The TRO was modified to release the operating funds within a matter of weeks, and the case was resolved through a settlement that included no admission of liability.

The bridge before the next step: if you have already tried to engage with the court on your own and the motion was denied or the plaintiff opposed it successfully, the analysis shifts. A second review looks at what argument was actually made, whether the brief hit the right standard, and what other procedural options remain – including whether an amended motion or an interlocutory appeal of the TRO ruling is realistic.

Step 6 – Address the Amazon account and funds in parallel

Winning a TRO modification in federal court does not automatically unfreeze your Amazon account. Amazon acts on court orders, but it also has its own internal hold processes, and the two do not always move in sync.

Once the court has entered an order modifying or dissolving the TRO as to your account, that order needs to be served on Amazon's registered agent and tracked through Amazon's legal compliance team. Amazon will typically comply with a clear court order releasing the freeze, but the internal process has its own timeline. In matters we handle, we send the order directly to the relevant contacts, confirm receipt, and follow up until the disbursements resume. Leaving this to chance means a seller who won in court still has frozen funds for weeks longer than necessary.

Separately, the asset freeze may have covered payment processors – PayPal, Payoneer, Stripe, or a bank account – in addition to Amazon. Each processor has its own compliance process for court-ordered releases. A court order that names Amazon specifically may not automatically release a hold at a payment processor that was named in the original TRO; the release language needs to cover each affected institution.

A fashion-accessories seller on Amazon US (summer 2026) reached us after successfully obtaining a TRO modification but finding that their Payoneer balance remained frozen three weeks later. The original court order used language that referenced "the Marketplace" without specifically naming the payment processor by the correct legal name. We drafted a clarifying order for the court's signature and served it on Payoneer's legal compliance team, which resolved the hold. The lesson is practical: the language of the release order matters as much as getting the order itself.

Step 7 – Build the record for ongoing compliance and relisting

After the TRO is dissolved or modified and the funds are released, the case is not necessarily over. The plaintiff may continue the action against you as a severed defendant, seek a preliminary injunction on different grounds, or pursue full merits litigation. More commonly, the case resolves through settlement or dismissal at this stage – but you need a clean record for that resolution to hold.

Building the record means: obtaining a formal dismissal with prejudice (or at minimum a covenant not to sue that covers the specific products at issue), ensuring any settlement or consent order is filed with the court, and getting confirmation from Amazon that the related listings and account health issues have been addressed. A settlement that is not memorialized in a court filing can leave the original judgment risk technically open.

Relisting the affected products, where appropriate, requires coordinating the court order, the settlement terms, and Amazon's own IP complaint and listing-reinstatement processes. If the original complaint included a Brand Registry rights-owner complaint, that complaint may still be active in Amazon's system even after the federal case is resolved. Clearing the listing issue sometimes requires a separate retraction from the plaintiff or a separate Brand Registry appeal process.

The myth worth addressing directly: being named in a Schedule A complaint does not mean an automatic loss. The procedural structure of these cases – sealed complaint, ex parte TRO, immediate asset freeze – is designed to move faster than defendants can respond. But the speed of the initial order is not the same as the strength of the underlying case. Many Schedule A plaintiffs are filing against large volumes of defendants precisely because individual litigation would be economically impractical for them. A defendant who appears, raises substantive defenses, and contests joinder is a fundamentally different posture than the typical non-appearing defendant who defaults.

Before the FAQ section: if you received a rejection of a prior TRO dissolution motion, or you have already been defaulted and are considering a motion to vacate, the analysis is different from a first-appearance strategy. In those situations, a second read on what happened and what is still open can identify whether there is a viable path.

Frequently asked questions about improper joinder of defendants

How long does resolving improper joinder of defendants usually take on Amazon US?

The timeline turns on the court's docket, the plaintiff's responsiveness, and whether the motion is opposed. Courts typically set a hearing on TRO-related motions within a compressed window after filing because the TRO itself has a statutory duration. In many matters, a well-filed severance and TRO-dissolution motion produces a ruling or a court-pressured resolution within several weeks of filing. Settlement discussions that run alongside the motion can move faster or slower depending on the plaintiff's posture. No timeline is guaranteed, and a contested motion in a busy federal district can take longer than the TRO calendar suggests.

What are the main risks if I handle improper joinder of defendants alone?

Federal motions practice has specific formatting, briefing, and procedural requirements that vary by district and by judge. A motion that does not comply with local rules may be stricken before the court reads the argument. More substantively, raising improper joinder without simultaneously addressing personal jurisdiction can waive the jurisdictional defense permanently. Sellers who file pro se responses that read as general denials rather than targeted procedural motions often find that the court treats the filing as an answer, triggering the full litigation schedule rather than resolving the freeze quickly. Missing the preliminary injunction response deadline is also a common and serious error for self-represented defendants.

Do I need a lawyer for improper joinder of defendants?

You are not legally required to retain counsel, but the practical arguments for doing so in a Schedule A case are strong. The procedural stakes are high: a misstep on joinder, jurisdiction, or TRO response timing can waive defenses permanently or convert a resolvable freeze into a default judgment. The argument for improper joinder is also a legal argument, not a factual narrative – it requires reading the Federal Rules, the complaint, and the court's local rules together and presenting a brief that meets that court's standards. Tutamen's Schedule A practice handles these matters on a fixed-fee basis, quoted after a short review of the complaint and TRO, so the cost is known up front.
