Introduction
Receiving notice of an Employment Tribunal claim is unsettling for any business, whether you’re a small employer handling it directly or an HR team managing it alongside everything else. The good news is that the process is structured and predictable once you understand the key steps — and getting the early decisions right, particularly around your response deadline, matters considerably more than most employers realise until it’s too late.
This guide walks through what to do from the moment a claim arrives, written specifically for employers rather than claimants.

What Happens When You Receive an ET1
A tribunal claim starts life as a form called the ET1, submitted by the claimant (usually after they’ve been through ACAS Early Conciliation). Once the tribunal accepts the claim, it’s sent to you as the respondent, along with details of the case and the deadline for your response.
It’s worth reading the ET1 carefully and completely before doing anything else — the specific claims being brought, the dates referenced, and the remedy being sought all shape how you should respond, and rushing this first read is a common source of avoidable mistakes later in the process.
Responding: The ET3 and the 28-Day Deadline
Your formal response is made using form ET3, and you generally have 28 days from the date the claim was sent to you to submit it. This deadline is applied strictly, and it’s genuinely one of the most important dates in the entire process — far more employers underestimate this than overestimate it.
Your ET3 should set out clearly whether you dispute the claim, admit any part of it, and the factual and legal basis for your position. As with the claimant’s ET1, this document shapes the scope of what follows, so it’s worth treating it with real care rather than as an administrative formality to get out of the way quickly.
What Happens If You Ignore the Claim
Failing to respond within the deadline carries genuine consequences — a tribunal can enter a default judgment against you without a full hearing, potentially deciding liability, and sometimes remedy, in your absence. Reversing a default judgment afterwards is possible in limited circumstances but is far harder, slower, and less certain than simply meeting the original deadline. If you’re struggling to respond in time for a genuine reason, it’s far better to seek an extension or urgent advice than to let the deadline pass and hope to sort it out afterwards.
Should You Try to Settle Early?
Many tribunal disputes never reach a final hearing, and it’s worth genuinely considering early on whether settlement makes sense for your business, rather than treating it as a late-stage fallback. The calculation isn’t just about the strength of the underlying claim — it’s about the cost of defending it through to a hearing, the management time it will absorb, and any reputational considerations, weighed against what a reasonable settlement figure would cost.
This doesn’t mean settling every claim regardless of merit — a weak claim may be worth defending robustly. But dismissing settlement on principle, without weighing what a claim could realistically cost you if it succeeds against the practical cost of litigation, is a common and often expensive mistake.
Preparing Your Defence
If you’re proceeding to defend the claim, preparation follows a broadly similar structure to what a claimant goes through: gathering relevant documents, preparing witness statements from the people actually involved in the events in question, and complying with whatever directions the tribunal issues on disclosure and evidence exchange — a process that, like the tribunal timeline generally, often runs longer than businesses expect. Being organised and responsive to tribunal deadlines throughout this stage reflects well on your credibility generally, and genuinely reduces the risk of unnecessary procedural complications later.
Understanding Your Costs Risk as an Employer
It’s worth knowing upfront that winning a tribunal claim doesn’t automatically mean you will recover your legal costs. Employment Tribunals generally expect each side to bear its own costs regardless of outcome, and a costs order against the claimant — even where you successfully defend the claim — is the exception rather than the norm, typically reserved for genuinely unreasonable conduct on their part. This is quite different from civil litigation, where costs more often follow the outcome, and it’s an important expectation to set internally before deciding how to approach a claim.
Do You Need Legal Representation?
There’s no legal requirement for an employer to be represented at tribunal, and some straightforward claims are managed internally by an HR team. Whether that’s the right approach depends heavily on the complexity of the claim, what’s potentially at stake, and whether the claimant is represented — facing a represented claimant without your own support can be a genuinely difficult position to manage well without relevant experience.

Every tribunal claim starts with the same tight window to respond correctly, and the decisions made in those first 28 days — how you respond, whether you explore settlement, and how you prepare — tend to shape everything that follows.
Final Thoughts
Facing an Employment Tribunal claim as an employer is manageable with the right approach — meeting your response deadline, honestly weighing settlement against the cost of defending, and preparing thoroughly if you proceed. The businesses that struggle most tend to be the ones that underestimate the early deadlines, not the ones that ultimately lose on the merits.
Frequently Asked Questions
What should I do first if I receive an Employment Tribunal claim?
Read the ET1 carefully to understand exactly what’s being claimed, then start preparing your response — you generally have 28 days to submit form ET3, and this deadline is strictly applied.
What happens if I miss the response deadline?
A tribunal can enter a default judgment against you without a full hearing, which can be difficult and uncertain to reverse afterwards. If you’re at risk of missing the deadline, seek an extension or urgent advice rather than letting it pass.
Will I get my legal costs back if I win?
Not automatically. Employment Tribunals generally expect each side to bear its own costs regardless of outcome, and a costs order against the claimant is the exception, not the norm.
Should I try to settle instead of defending the claim?
It’s worth genuinely considering, weighing the cost and management time of defending through to a hearing against a reasonable settlement figure — rather than settling automatically or refusing to consider it on principle.
Do I need a solicitor to respond to a tribunal claim?
Not as a legal requirement, though it depends on the complexity of the claim and whether the claimant is represented. A straightforward claim may be manageable internally; a more complex one often benefits from experienced support.
What happens if I win my appeal?
Yes. Claims can settle at any stage, including after a response has been filed, right up to and even during a final hearing.
