Received an employment tribunal claim?

You have 28 days to file your response, known as the ET3. The clock starts on the date the tribunal sent the claim, not the day you opened it. If your response is late or missing, a default judgment can follow.

We'll draft your ET3 response and grounds of resistance for a fixed fee of £350.

We'll call you within 48 hours of your enquiry, and you'll have a first draft within 24 hours of that call.

How our £350 ET3 package works.

01 Send us the claim form the tribunal sent you.

02 We call you within 48 hours to go through what happened and the key dates.

03 You get a first draft of your ET3 response and grounds of resistance within 24 hours of that call.

04 We agree the final version with you, ready to submit.

One fixed fee. No hourly billing.
