Checklist: Preserving privilege: what every in-house lawyer needs to know (UK)

Updated as of: 27 March 2026
This checklist provides practical guidance on how to recognise and preserve legal professional privilege and will be of use primarily for in-house counsel based in England and Wales. While the checklist can be employed daily as a practical tool when privilege is being considered, it is especially useful as a precautionary tool when an organisation is dealing with internal investigations, regulatory scrutiny or litigation. The checklist covers key principles, practical steps, recent regulatory developments and case law to help avoid inadvertent waiver or loss of critical privilege protections.
