What happens after you file a Notice of Dispute: what to do, step by step

A flat rejection from Amazon UK's seller support can feel like the last word. It is not. Filing a Notice of Dispute is the formal opening of a structured process that exists outside the support queue – one with its own timeline, its own decision points, and, for sellers who use it correctly, real commercial leverage. But the process only works if you know what comes next.

TL;DRAfter you file a Notice of Dispute with Amazon, a defined informal-resolution period begins during which both sides are expected to negotiate in good faith. If that window closes without resolution, the seller can escalate to a pre-arbitration demand or formal arbitration under the dispute-resolution terms of the Amazon Business Solutions Agreement (BSA). The path depends on the BSA version that applies to the account, which should be verified before any filing.

This guide walks through the step sequence from the moment a Notice of Dispute lands at Amazon's registered address to the point at which you either reach a resolution or make a considered decision to escalate. Each stage carries a distinct risk of error. The sellers who get the best results are the ones who understand those risks before they reach them.

What is a Notice of Dispute, and what does it actually trigger on Amazon UK?

A Notice of Dispute is the formal written demand that starts the clock on Amazon's contractual dispute-resolution process – it is not a complaint ticket, and it is not a legal claim in court.

Under the BSA, Amazon and its third-party sellers agree in advance to a multi-step process before any party can go to formal arbitration. The Notice of Dispute is the mechanism that activates that process. On Amazon UK, the relevant entity is Amazon EU S.à r.l., and the notice must be sent to the address or contact route specified in the BSA version that governs the account. Sending it to seller support by chat does not constitute a valid filing.

What does the notice actually trigger? Two things simultaneously. First, it creates a written record that the seller has attempted to resolve the dispute informally – a prerequisite that matters if arbitration becomes necessary later. Second, it starts an informal resolution period, typically a defined number of weeks, during which Amazon is obliged to engage. The exact length of that period is governed by the applicable BSA version, which we check at the outset of every matter in our practice. Using the wrong version, or misreading the notice requirements in it, is one of the most common procedural errors sellers make alone.

A Notice of Dispute is not the nuclear option – and that is exactly the myth worth correcting early. In our experience, a significant share of matters filed correctly through this channel are resolved without ever reaching formal arbitration. The notice is a business tool as much as a legal one.

What are the immediate steps after the notice is filed?

Once the Notice of Dispute is properly filed, the seller must move into a structured holding pattern – active, not passive – while the informal resolution window is open.

Step one is confirmation. You need documentary evidence that the notice was received by the correct party at Amazon. If sent by tracked post or a verifiable electronic method, preserve that record. If Amazon acknowledges receipt directly, preserve that too. The downstream risk of skipping this step is that Amazon later disputes the start date of the informal period, which shifts the escalation timeline in its favor.

Step two is organizing your substantive file. The informal resolution period is not a time to wait. It is the period in which you should be building – or strengthening – the factual and contractual case you will present. That means: a chronological account history showing what happened and when; copies of every relevant notice, email, or policy communication from Amazon; a clear statement of the specific remedy you are seeking (funds released, account restored, a specific sum reimbursed); and the contractual basis for each element of your claim under the BSA.

Step three is the initial communication to Amazon's escalations or legal contact. A Notice of Dispute filing often routes internally to a team that has more authority than frontline seller support. The first substantive communication you send into that channel sets the tone. A well-evidenced, commercially specific letter – not an emotional narrative – is what produces a response worth having. In matters we handle at this stage, we draft that opening position to present the claim as a defined legal obligation, not a request for a favor.

What goes wrong here? Sellers frequently use the informal period to send the same information they already sent through support, re-packaged. That produces the same answer. The informal resolution period calls for a different document: one that references the contractual terms, names the specific BSA provisions in play, and articulates the precise remedy. For a practical grounding in how to structure that communication, our guide on responding to a Notice of Dispute to Amazon the right way covers the structural requirements in detail.

How does the informal resolution period work – and when does it close?

The informal resolution period is a contractually defined window that functions as a negotiation phase; neither side is obligated to concede, but both are expected to engage meaningfully.

During this window, Amazon may respond through its in-house legal, policy, or escalations teams. Responses vary considerably. Some are substantive counter-positions. Others are templated non-responses that acknowledge the filing but offer nothing. The seller's job is to treat every communication – however formulaic – as an opportunity to sharpen the written record, because that record becomes the evidentiary foundation if the matter escalates to the American Arbitration Association (AAA).

There is a practical discipline here that matters commercially. Keep every exchange in writing. If Amazon proposes or makes contact by phone, follow up the call with a written summary of what was discussed and send it to the same contact channel. This protects the timeline and prevents disputes about what was actually agreed or offered during the informal phase.

The informal window closes in one of three ways. First, the parties reach a written settlement – funds are released, the account is restored, or some other agreed remedy is confirmed. Second, the window simply expires without resolution. Third, Amazon formally declines to engage further within the window. In the second and third scenarios, the seller faces a decision point: escalate to a pre-arbitration demand and, if necessary, formal arbitration, or accept the outcome as it stands.

That decision is not automatic. It depends on the size of the claim, the strength of the contractual position, the costs of escalation, and – critically – the seller's commercial situation right now. A seller who is still operating and has other recovery options faces a different calculus than one whose entire account balance is frozen and whose business is at a standstill.

What is the seller's decision point at the end of the informal period?

When the informal window closes without resolution, the seller must choose between three realistic paths – and this is where having clear legal advice matters most.

The first path is a pre-arbitration demand. This is a formal written demand sent before any AAA filing, setting out the claim in full and giving Amazon a final defined period to respond before formal proceedings begin. In many matters, this is the most effective tool in the sequence. A pre-arbitration demand, properly drafted, signals that the seller is prepared to proceed to formal arbitration and has the legal standing and documentation to do so. That signal, in our experience, frequently produces a more substantive response than the informal period generated. The commercial and legal reality for Amazon is that defending a large number of small arbitration claims through the AAA carries significant costs and procedural burden on its side too.

The second path is formal arbitration before the AAA. The BSA dispute-resolution terms specify the applicable arbitration rules and the seat of arbitration – but because those terms are subject to change and the applicable version varies by account and jurisdiction, the path depends on the BSA version that applies to the account, which we check first. What sellers should understand is that AAA consumer arbitration, where it applies, carries a different cost structure than commercial arbitration, and the threshold for what is economically viable to pursue shifts accordingly. For a full comparison of these paths, our guide on arbitration and pre-arbitration demands: the complete guide for sellers sets out the trade-offs in detail.

The third path is to accept the current outcome and look for alternative remedies. This is not always capitulation. In some matters, a separate regulatory route – a complaint to the relevant national authority under the Platform-to-Business (P2B) Regulation or the Digital Services Act (DSA), for example – produces faster commercial relief than continuing the BSA dispute path. Amazon, as a Very Large Online Platform (VLOP) under the DSA, operates an internal complaint-handling system that is separate from the BSA arbitration mechanism and has its own procedural requirements. On Amazon UK specifically, the P2B Regulation gives sellers defined rights to a statement of reasons for adverse account decisions, which can open a parallel line of challenge.

If the notice cites a funds-hold or reserve dispute → the pre-arbitration demand route has the strongest contractual footing, because the BSA contains specific disbursement obligations. If the notice cites a performance-based deactivation → the P2B and DSA routes may run faster and at lower cost, particularly for smaller claims. If the notice involves an IP or counterfeit complaint → the claim may need to run through the Brand Registry counter-notice mechanism alongside – not instead of – the BSA process.

Where does the process go wrong when sellers handle it alone?

The most common failure point is treating the Notice of Dispute as another support ticket – a narrative submission hoping for a sympathetic read.

A Notice of Dispute proceeding is a legal process. Amazon's internal teams on the receiving end of one treat it as such. Sellers who do not match that register – who describe their situation rather than defining their claim under the BSA – find that the informal period ends without any substantive engagement on the merits. The window closes. The claim is no stronger than when it started. And a re-filing or escalation faces the same underlying weakness.

A second failure point is letting the informal period expire passively. Sellers sometimes assume that if Amazon does not respond within the window, the matter has "defaulted" in their favor, or that patience will prompt Amazon to act. Neither is generally true. The expiry of the informal period simply opens the door to escalation; it does not resolve the underlying claim.

A third – and often most commercially damaging – failure is escalating to full arbitration before exhausting the pre-arbitration demand step, particularly for mid-size claims. AAA filing fees and arbitrator costs represent a material upfront expenditure. If a well-drafted pre-arbitration demand would have produced a settlement at a fraction of that cost, the premature filing has consumed resources without advantage.

A UK-based apparel seller on Amazon UK (winter 2025) came to us after two rounds through the informal period had produced only template responses from Amazon. The substantive issue was a held balance running to a mid-five-figure sum, withheld after a performance-related deactivation that the seller believed had already been resolved at the Account Health level. We reviewed the BSA version applicable to the account, drafted a pre-arbitration demand with a detailed contractual analysis of the disbursement obligation, and sent it with a defined response window. The matter settled before any AAA filing. The seller had previously filed the Notice of Dispute twice without legal input; the pre-arb demand produced a different quality of engagement from Amazon's side within days.

For sellers wondering whether this escalation actually puts the account at risk, our analysis of whether a pre-arbitration demand letter is the end of your account addresses that concern directly.

What should you actually do after reading this guide?

The steps above describe the standard procedural path. Where you are in that path – and what your next move should be – depends on the exact wording of the BSA version that governs your account, the current status of the informal period, and the specific nature of the claim. Those are the first three things we look at in every matter.

If your Notice of Dispute has already been filed and the informal period is running, the most important thing you can do right now is not submit another unstructured communication into that channel. Every exchange during the informal window shapes the record. A misfiled communication can narrow the claim or inadvertently introduce a concession that affects the escalation.

If the informal window has already closed without resolution, the decision between a pre-arbitration demand and formal arbitration is live. That decision should be made with a clear view of the contractual position, the realistic cost of each path, and the commercial value of the claim – not based on frustration or a general sense that "something must be done."

Frequently asked questions

How long does resolving what happens after you file a notice of dispute usually take on Amazon UK?

Resolution timelines vary significantly depending on the complexity of the claim and whether the matter settles during the informal period or escalates further. The informal resolution window itself is a defined period under the applicable BSA version – typically measured in weeks, not months. If the matter proceeds to a pre-arbitration demand, a further response window applies. Full AAA arbitration, where it becomes necessary, takes considerably longer. In our practice, a material share of matters are resolved at the pre-arb demand stage without reaching formal arbitration proceedings.

What are the main risks if I handle what happens after you file a notice of dispute alone?

The three principal risks are: filing the notice or follow-up communications to the wrong contact point, which may invalidate the timeline; using the informal period to re-submit support-style narratives rather than a contractually grounded claim, which produces no substantive engagement; and escalating directly to formal arbitration without a pre-arbitration demand step, which incurs AAA fees that a well-drafted demand might have avoided. The evidentiary record built during the informal period also matters if arbitration follows – weaknesses in that record are hard to correct later.

Do I need a lawyer for what happens after you file a notice of dispute?

There is no formal requirement to be represented by a lawyer in a BSA dispute process. However, the process is a legal one, and Amazon's internal teams on the receiving end treat it as such. Sellers who handle it without legal input frequently misidentify the applicable BSA version, misdraft the substantive position, or miss the procedural steps that protect the escalation path. Engaging legal representation at the Notice of Dispute or pre-arbitration demand stage – rather than after an informal period has already been wasted – consistently produces better-positioned matters in our experience.
