How to use HMCTS Common Platform

Published 2022-03-25Last updated 2026-06-01

Common Platform is a case management system for HMCTS, the judiciary, and professional court users, including defence.

Defence solicitors and barristers will need to register for an account before any hearings they attend where Common Platform is used.

With an account you can:

  • link yourself to a case or defendant so the Legal Aid Agency is informed for payment purposes
  • self-serve case materials, including the initial details of the prosecution case (IDPC) and the preparation for effective trial form (PET form) in the magistrates’ court
  • serve documents on the court for Common Platform cases in the magistrates’ court

Once your firm has registered and you have activated your account, you can start managing your cases in Common Platform.

If you are an organisation administrator, see the HMCTS Common Platform for defence administrators guide.

Once your organisation has registered and you have activated your account, you can start accessing cases in Common Platform.
