The ET1 (formerly IT1) is the standard form on which the Claimant’s tribunal claim is written. It is also known as the “originating application”. The current format of the ET1 which was introduced in 2013 is user unfriendly and has met much criticism from legal practitioners.
The ET3 (formerly IT3) is the standard form on which the employer’s (the Respondent’s) response or defence to the Claimant’s ET1 is written.
