About Common Platform

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

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 pre-trial readiness form (PET form) in the magistrates’ court
  • serve documents on the court for magistrates’ Common Platform cases

How to register
