MG Forms

Use this guide to understand and access standard Manual of Guidance (MG) templates. These forms are used across the criminal justice system in England and Wales to prepare, structure, and submit prosecution files.

What MG Forms Are

The standardisation of criminal casefiles is governed by the National File Standard (NFS), which is incorporated into the Director's Guidance on Charging (Sixth Edition).

Historically, the framework was set out in the national Manual of Guidance. To ensure consistency across different agencies, investigators use numbered forms with the prefix 'MG' to compile evidence, outline case facts, and share data securely with prosecutors.

Transition to the Digital Case File (DCF)

The criminal justice system is progressively moving toward integrated software systems and the Digital Case File (DCF).

Under the DCF framework, many traditional paper and standalone word-processing templates are being retired. They are increasingly replaced by direct, dynamic data fields completed within secure, local police platforms. Standalone templates, however, remain a critical reference for training, auditing, and file compilation by independent investigators, regulators, and non-police prosecuting agencies.
