Improper joinder of defendants: what to do, step by step on Amazon US

A federal order froze your Amazon US funds before you even knew a case existed. That is one of the defining features of the Schedule A Defendants scheme – speed and secrecy, by design. What comes next is not automatic, and being named in the case does not mean the outcome is decided.

TL;DRImproper joinder of defendants in a Schedule A case occurs when a plaintiff bundles dozens or hundreds of unrelated sellers into a single federal complaint to gain strategic advantages – principally, a single filing fee and a single TRO covering every defendant's marketplace accounts and payment processors. The legal cure is a motion to sever and dismiss for misjoinder, which, when granted, dissolves or narrows the asset freeze and restores the ability to negotiate from a position of strength.

This guide walks through the actual procedural sequence: from the moment you discover the freeze to the point where the joinder issue is either resolved or traded away in settlement. Each step identifies what can go wrong and how to avoid the mistakes that cost sellers their best leverage.

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

Joinder of defendants is improper when the claims against each seller do not arise from the same transaction or occurrence, and when there is no common question of law or fact linking all of them – the two requirements under Federal Rule of Civil Procedure 20 for joining multiple parties in one case.

In the SAD scheme, a brand or its litigation counsel files a single complaint naming dozens to hundreds of online marketplace sellers under a Schedule A exhibit. Each seller is typically an independent business that operates its own storefront. The connection between them is, at best, that they all sell goods the plaintiff alleges infringe the same trademark or patent. That shared allegation is rarely enough to satisfy Rule 20's actual requirements. Courts in the Northern District of Illinois – historically the most common venue for these filings – have split on the issue. Some have granted severance motions. Others have tolerated broad joinder at the TRO stage and severed later. The trajectory matters more than the initial ruling.

Why does the plaintiff bundle defendants this way? The commercial logic is transparent. One filing fee covers every defendant. One ex parte TRO motion reaches every account. The plaintiff's counsel then manages a settlement-harvesting operation: most defendants settle quickly because the cost of defending individually appears to exceed the settlement demand. Understanding that logic is the first step to evaluating whether fighting the joinder issue is worth the effort for your specific situation.

In matters we handle, improper joinder is almost always present in the original complaint – but whether it is worth pressing as a standalone motion depends on the account balance frozen, the settlement demand, and how quickly the plaintiff has been moving against other defendants in the same case.

Step 1 – Identify the case and secure the operative documents

Your first concrete task is to confirm the exact case name, docket number, presiding court, and the date of the TRO before doing anything else. The asset freeze on your Amazon account traces to a specific order, and the deadline to respond – if one exists in the order – runs from a date in that document, not from when you learned about it.

Amazon's Platform notifies affected sellers, but those notifications are often delayed and sometimes incomplete. The asset freeze and the payment-processor hold may appear at different times. Do not rely on what Amazon's notification says the order covers; obtain the actual court filings.

Sources for the documents:

• PACER (Public Access to Court Electronic Records) – search by case number if you have it, or by plaintiff name or the storefronts alleged in the complaint.
• The TRO itself identifies the plaintiff, the presiding judge, and any hearing date already scheduled.
• The Schedule A exhibit attached to the complaint will list your storefront or account identifier – confirm your entry before taking any position.

Once you have the TRO and the complaint, read the show-cause hearing date. That date sets the outer limit for any motion to dissolve or modify the TRO, and in some orders it arrives within days of service. Missing that date without having filed any response effectively converts the TRO into a preliminary injunction by default.

A second critical document is the bond. Federal courts require plaintiffs to post a bond when obtaining an ex parte TRO. The bond amount is typically modest relative to the aggregate freeze – often disproportionately small when dozens of defendants are frozen simultaneously. The bond amount matters if you later move for damages caused by a wrongful freeze.

Step 2 – Assess the joinder argument and weigh it against alternatives

A misjoinder argument is strongest when your storefront has no traceable connection to any other defendant in the case – different supply chains, different product lines, different geographic markets, no overlapping business relationships. The weaker the thread connecting you to other defendants, the stronger the Rule 20 argument.

The realistic options at this stage are:

• Move to sever and dismiss for misjoinder: This is the most aggressive path. If granted, you are removed from the case and the TRO freezing your accounts dissolves as to you. The downside is time and legal cost, and courts vary significantly in their willingness to sever at the TRO stage.
• Move to dissolve or modify the TRO on the merits: You can challenge the TRO directly by attacking the plaintiff's showing of likelihood of success, irreparable harm, or the scope of the asset freeze, without necessarily pressing the joinder argument at all.
• Seek early settlement to unfreeze the account: Many plaintiffs in the SAD scheme are settlement-focused from day one. A negotiated resolution ends the freeze fastest, but the terms matter – specifically, the scope of any injunction you agree to and whether it affects other platforms or product categories.
• Appear and answer, preserving all defenses: If the hearing date is far enough out and the frozen balance is significant, entering an appearance, asserting misjoinder as an affirmative defense, and conducting focused discovery on the plaintiff's actual damages is sometimes the right sequence.

The decision matrix in practice looks like this: if the frozen balance is modest and the settlement demand is proportionate, early resolution is often the commercial choice. If the balance is substantial – a mid-five-figure sum or above – and the plaintiff's evidence is thin, the joinder/severance motion and a parallel TRO-modification motion become worth the effort. If the plaintiff cannot credibly demonstrate how your storefront's sales caused it irreparable harm distinct from every other defendant's sales, the TRO is vulnerable on both the joinder and the merits grounds simultaneously.

We regularly see sellers assume that paying the settlement demand is the only realistic option. It is not, but the analysis has to be grounded in the specific order, the specific judge's history with these cases, and the actual balance at stake.

Step 3 – File the motion to sever (and what must be in it)

A motion to sever under Rule 21 must do more than recite that the defendants are different businesses. It has to demonstrate, with specificity, that the plaintiff has not alleged – and cannot allege – that your conduct and the other defendants' conduct arose from the same transaction or a series of related transactions, and that no genuine common question of fact links you to them in any material way.

The argument has two moving parts. First, the "same transaction or occurrence" prong: selling the same type of goods under the same trademark at roughly the same time is not a transaction or occurrence. Courts that have granted severance in these cases have found that independent sales by independent sellers on a common marketplace are not a single transaction merely because they all happened on Amazon and allegedly infringed the same mark. Second, the "common question" prong: alleging that all defendants committed the same type of infringement is a common legal theory, not a common question of fact. Facts about your sourcing, your pricing, your inventory, and your customer base are entirely separate from any other defendant's facts.

Practical elements the motion should address:

• A concise description of your business – what you sell, how you source it, how you operate your storefront – to establish factual independence from the other defendants.
• A specific challenge to the plaintiff's basis for grouping you with the others: what is the pleaded connection, and why does it fall short of Rule 20?
• A request for dissolution of the TRO as to you specifically, or at minimum modification to release funds needed for ordinary business operations while the motion is pending.
• A note on the bond: if the bond is insufficient to cover your potential damages from a wrongful freeze, flag that for the court.

Courts in the Northern District of Illinois and the Southern District of New York have issued severance orders in Schedule A cases, though outcomes vary by judge and by the specific allegations in the complaint. Citing the relevant precedents from the same district and, where possible, the same judge's prior rulings is essential – generic severance case law from other contexts is less persuasive.

One procedural point that trips sellers up: some courts require a pre-motion conference before a substantive motion. If the presiding judge's standing order requires one, filing the motion without the conference can result in an automatic strike – a costly error when the show-cause hearing is already scheduled.

Step 4 – Preserve your defenses at every stage

Appearing in the case without asserting misjoinder as an affirmative defense in your first responsive pleading is a waiver risk. Federal courts treat certain defenses as waived if not raised early. Misjoinder is listed under Rule 21, which technically gives courts authority to add or drop parties "at any time," but the practical window to raise it forcefully – and before the plaintiff has moved the case forward on the merits – is narrow.

Your Answer, or any motion that precedes it, should preserve:

• Misjoinder / improper joinder of defendants under Rule 20 and Rule 21.
• Personal jurisdiction, if the plaintiff's allegations about your contacts with the forum are thin.
• Substantive defenses to the IP claim: authorization, first sale, descriptive fair use, or non-infringement, depending on whether the claim is trademark or patent-based.
• Any affirmative defenses specific to the freeze: the bond is inadequate; the plaintiff did not give required notice; the scope of the asset freeze exceeds what the court authorized.

One of the most consequential errors we see is a seller who responds to the plaintiff's counsel directly – often through a brief phone call or email – and makes factual representations about the account, the sourcing, or the business without having entered a formal appearance and without counsel. Those representations can narrow the defenses available later.

Step 5 – Navigate the show-cause hearing and the TRO timeline

A TRO issued ex parte has a limited lifespan under the Federal Rules – fourteen days by default, extendable for good cause – but plaintiffs in Schedule A cases routinely seek extensions, and judges frequently grant them when defendants have not appeared. The practical consequence is that the freeze can persist well beyond the statutory default period if you do not engage the process.

The show-cause hearing is your first real appearance before the judge. Its purpose is for the plaintiff to justify why the TRO should convert to a preliminary injunction. That is your opportunity to contest the continuation of the freeze, challenge the sufficiency of the plaintiff's evidence, and press any pending severance motion simultaneously.

What to bring to the show-cause hearing:

• Evidence of your account's operating history: inventory levels, sales velocity, ordinary disbursement cycle – to demonstrate that the freeze is causing ongoing, concrete harm to a legitimate business.
• Any evidence bearing on the underlying IP claim: authorization documents, purchase records, or product-authenticity documentation that undercuts the plaintiff's likelihood-of-success showing.
• Your severance argument, in full – both the Rule 20 / Rule 21 legal standard and the factual showing of your independence from the other defendants.

Judges have discretion at the show-cause stage. Some will sever voluntarily after hearing the argument, even without a formal prior motion, if the misjoinder is clear on its face. Others will allow the case to proceed in a consolidated posture through the preliminary-injunction phase and address individual defendants' arguments later. Reading the judge's history with these filings in advance of the hearing is one of the most useful pieces of preparation.

Step 6 – Evaluate the settlement path and its trade-offs

Settlement in Schedule A cases is almost always on the table. The plaintiff's litigation model depends on it. But accepting a settlement without scrutinizing its terms can create problems that outlast the immediate case.

The terms that matter most:

• The scope of the injunction you consent to: A permanent injunction that covers not just the accused products but any goods bearing a brand family of marks – across all platforms, not just Amazon – can limit your business for years. Narrowing the injunction to the specific products and the specific mark at issue is almost always worth the negotiation.
• The cash component: Settlement demands in the SAD scheme vary widely. If the plaintiff's actual damages evidence is thin and the joinder argument is strong, the leverage to reduce the demand is real. What you cannot recover, if you settle without pressing the joinder issue, is the cost of the freeze itself during the period between the TRO and settlement.
• Platform notification: Some settlement agreements require the plaintiff to notify Amazon to release the freeze. Others leave that step to the seller. Confirm in writing who is responsible for the platform-side release and within what timeframe.
• Confidentiality: Standard in these settlements, but confirm that the confidentiality clause runs both ways and does not prevent you from disclosing the fact of the settlement to your insurers or accountants.

A home-goods FBA seller on Amazon US (winter 2025) came to us after being named in a Schedule A complaint alongside more than eighty other defendants. The plaintiff's counsel sent a settlement demand within days of the TRO. We reviewed the complaint, confirmed that the factual connection between our client's storefront and the other defendants was limited to a shared marketplace and a shared product category, and filed a motion to sever alongside a motion to modify the TRO to release operating funds pending resolution. The plaintiff revised its settlement position before the show-cause hearing. The account was released and the case resolved on narrowed injunction terms.

The same analytical sequence applies across the spectrum – whether you ultimately move through litigation or to settlement, the joinder analysis is the foundation of your position.

Where this goes wrong: the five most common errors

Being named in a Schedule A case does not mean an automatic loss. That is the myth that plaintiff's counsel implicitly sells when it contacts defendants informally before they have engaged their own representation. The reality is that the joinder structure is frequently vulnerable, the bond is often undersized relative to aggregate harm, and the plaintiff's damages evidence is commonly thin at the TRO stage.

The errors that foreclose options:

• Waiting past the show-cause deadline without appearing. Once the TRO converts to a preliminary injunction by default, the procedural cost of undoing the freeze increases substantially. The window is short. Acting within it is almost always better than waiting.
• Responding directly to plaintiff's counsel without representation. Pre-representation communications narrow the factual record in ways that are difficult to undo. They also create a dynamic where the plaintiff's counsel is, in effect, advising both sides of the negotiation.
• Treating the settlement demand as fixed. The initial demand in the SAD scheme is almost never the plaintiff's final number. The leverage to negotiate is highest before the preliminary-injunction stage – not after.
• Accepting broad injunction terms to close the case quickly. A permanent injunction that covers categories beyond the specific accused goods can block legitimate sourcing and selling activities for years. Reviewing the injunction language carefully is not optional.
• Not preserving all defenses in the first pleading. As noted in Step 4, waiver of procedural defenses is a real risk. The first responsive filing should be comprehensive even if it is brief.

In matters we handle, the sellers who have the best outcomes are those who engage the process early – within the TRO's initial window – with a clear analysis of the frozen balance, the joinder argument's strength, and the realistic settlement range. If a first set of communications with plaintiff's counsel has already occurred, a thorough review of what was said and when is the starting point.

If that first engagement has already happened without representation, a careful read of the full case posture is still worth doing. Email info@tutamenlaw.com with the case name and the date of the TRO, and we will assess what remains open.

Frequently asked questions on improper joinder of defendants

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

The timeline depends on how the case is resolved. A successful severance motion decided before or at the show-cause hearing can dissolve the freeze within a few weeks of the TRO. Settlement – the more common outcome – typically closes within several weeks to a few months of the TRO, depending on how quickly the parties reach terms and how long the platform-side release takes after settlement. If the case proceeds to a contested preliminary-injunction hearing, the timeline extends materially. The freeze persists throughout any litigation phase, which is one of the principal cost drivers and one of the reasons early engagement matters.

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

The primary risk is waiver. Federal procedural defenses – including misjoinder, personal jurisdiction, and challenges to the TRO's scope – must be raised at specific points. Missing the correct filing window can permanently forfeit arguments that would otherwise have been persuasive. A second risk is the settlement process itself: plaintiff's counsel in SAD cases is experienced at channeling unrepresented defendants toward standard-form settlement agreements with broad injunction terms. Without representation, there is typically no meaningful review of those terms before signing. A third risk is the asset freeze continuing by default simply because no appearance was filed before the show-cause deadline.

Do I need a lawyer for improper joinder of defendants?

Technically, an individual who is the sole defendant can appear pro se in federal court, but business entities – including LLCs and corporations – cannot appear without counsel in federal court as a matter of law. More practically, the procedural sequence in a Schedule A case is dense and time-sensitive. The joinder argument requires district-specific precedent analysis. The TRO-modification motion requires a factual showing that reads credibly to a federal judge. The settlement review requires understanding what the injunction terms will do to the business beyond the immediate case. Attorney-led representation is not a formality in this context; it is the operational tool that makes the procedural options available.
