The Tribunals Service has introduced a live webchat service for queries, in addition to the telephone support already available.
The service is open Monday to Friday 8:30am to 5pm.
It means that claimants completing an online form to lodge an appeal, for example, can get support in a pop-up window without having to leave the page they are working on.
Users can download a copy of a transcript of their chat or receive it by email, if they wish.
People using paper forms connected to their appeal are also free to use webchat, by visiting the gov.uk site.
