Privilege: A client guide - The key principles for pensions trustees and employers

25 May 2021


The law of privilege gives someone the comfort of knowing they can keep certain documents confidential and not have to provide them to third parties. However, working out whether a document is privileged can be tricky. In this Insight we set out some general principles and some basic tips to help ensure that, once a document is privileged, that privilege is not later inadvertently lost.

Whether a document is privileged can be fact-specific, if in doubt please contact a member of our Pensions Disputes Team.

What is privilege?

Privilege entitles a person to withhold a document from a third party, whether that be a trustee, an employer, a court, the Pensions Regulator (tPR) or HMRC. It is an absolute right, exercisable in and outside court proceedings.


A document cannot be privileged unless it is confidential so, if a privileged document ceases to be confidential, it will lose its privileged status.

The core categories of privilege

The three core categories of privilege are:


Is the document confidential?
Is the document a communication between a lawyer and a client?
Was the document produced for the dominant purpose of giving/obtaining legal advice?


Other categories of privilege, namely, joint or common interest privilege, also exist but they are not free-standing categories of privilege but depend on a document having already attracted legal advice or litigation privilege.

The test for legal advice privilege


Is the document confidential? Is the document a communication between a lawyer and a client? Was the document produced for the dominant purpose of giving/obtaining legal advice? Legal advice privilege is likely to apply.


If you cannot answer "Yes" to any of these questions, the document was either never covered by legal advice privilege or, having once been privileged, privilege was later lost, for example, because the document ceased to be confidential.

Who is a lawyer?

To be covered by legal advice privilege, the document needs to have been a communication between a client and their lawyer.

The term 'lawyer' covers solicitors, barristers or qualified foreign lawyers, as well as in-house lawyers so long as they are acting in a legal rather than commercial capacity. Privilege also extends to trainees and paralegals acting under the supervision of a lawyer.

Who is the client?

The definition of 'the client' is likely to be interpreted restrictively by the courts to refer to those members of the organisation with authority to give instructions to lawyers and receive their advice. Therefore, care needs to be taken when disseminating advice received within an organisation in case it is later suggested that confidentiality in that advice was lost by being shown to 'non-clients'.

Was the document produced for the dominant purpose of giving and obtaining legal advice?

The court decided in The Civil Aviation Authority v Limited, R. (on the application of) that to be covered by legal advice privilege the document must have been created for the dominant purpose of seeking and giving such advice. If that can be established, the document should be privileged even if it fulfilled another purpose, for example, seeking the commercial views of others. However, if the dominant purpose of the document was not to seek and provide legal advice, the document will not be covered by legal advice privilege even if one purpose of the document was to seek and obtain such advice.

The test for litigation privilege

This covers confidential communications (not necessarily between a client and its lawyers) or other documents produced for the dominant purpose of existing, pending or reasonably contemplated litigation. 'Litigation' can extend beyond court proceedings and include adversarial proceedings brought by public bodies such as tPR.


Is the communication between:
Lawyer / client
Lawyer / third party
Client / third party**
Is the document confidential?
Was litigation reasonably in prospect when it was produced?


**Note that litigation privilege is broader than legal advice privilege in that it can cover communications between a client's lawyer and a third party, as well as the client and a third party, if such communications were for the dominant purpose of litigation.

What is litigation?

Points to be aware of:

  • Litigation must be a real likelihood, not a mere possibility.
  • To be "litigation", investigations conducted by regulators such as tPR, the SFO and the FCA may be inquisitorial and so documents created for the purpose of them may not be covered by litigation privilege.
  • Documents created in the context of investigating and resisting a complaint to the Pensions Ombudsman may be privileged on the basis the process is litigation. However, aspects of the functions of the Ombudsman are inquisitorial and thought needs to be given to whether in a particular case documents will be covered by litigation privilege, particularly where the Ombudsman's Early Resolution Service is involved.

Without prejudice privilege

This prevents statements made in an attempt to settle a dispute from being put before the court. Labelling a document 'without prejudice' will not make it privileged if it was not a communication made in an attempt to settle. Conversely, not labelling a document 'without prejudice' will not preclude it from being privileged if it was a communication made to try to settle.

The test for without prejudice privilege


Is a dispute/complaint in existence?
Does the communications contain a meaningful offer to settle the dispute/complaint?
If yes, without prejudice privilege is likely to apply.


Other categories of privilege

Joint interest privilege

Where two or more parties retain the same legal adviser, each will be entitled to see privileged communications created after the retainer was concluded to which they were not originally a party if it has a joint interest in the subject matter of a privileged communication. Relationships where a joint interest can arise include beneficiaries and trustees, a company and its shareholders, partners in a partnership, and a parent company and its subsidiaries.


Has one or more party instructed the same solicitor? Or could they have both used the same solicitor?
Can they be said to have the same joint interest in seeking the advice from the solicitor?
If yes, Joint interest privilege likely to apply.


Common interest privilege

Common interest privilege enables the sharing of privileged documents with other parties who have the same interest. That interest needs to exist at the time of the disclosure of the communication. Examples of persons who may have a common interest may include employers and trustees, and companies in the same group. In practice it is prudent for parties to document the extent of the common interest before sharing privileged material.


Does LAP privilege and LP apply?
Does the potential recipient have a common interest in the subject matter?
Was the disclosure of the document on confidential terms?
If yes, common interest privilege is likely to apply.


Losing privilege

A privileged document may cease to be privileged in a number of ways. First, the document may cease to be confidential because it was provided to a third party.

For example, a pension scheme trustee might have provided a copy of privileged legal advice it received to the scheme's employer or to tPR. The advice will no longer be confidential vis-à-vis that third party, although it might still be confidential (and therefore privileged preserved) vis-à-vis other parties.

It will be important for the party sharing the advice it has received with another to make it clear to (or better agreed with) the intended recipient that it (i.e. the recipient) will only receive the advice for a specific and limited purpose, and that the recipient needs to keep the advice confidential.

Issues can arise when privileged legal advice is provided to corporate entities and that advice is disseminated within the organisation beyond individuals who have authority to instruct and receive from legal advisers. There is a risk that such dissemination will result in the advice ceasing to be confidential and, therefore, privileged.

It will be important to make clear the basis on which the advice is being disseminated within the organisation, to stress that it must be kept confidential and to limit the number of people with whom the advice is shared.

Privilege in a document might also be waived, for example, when a party seeks to deploy a privileged document in Court proceedings by relying on it in a statement of case or a witness statement. This area of law is not straight-forward and a party might be found to have waived privilege in a document even when they did not intend to do so.

Potential pitfalls

  • Board minutes - great care should be taken when legal advice is discussed. Lawyers should be present. Legal advice should not be reproduced in trustee/board minutes.
  • Dissemination of advice at the client end - avoid forwarding legal advice.
  • Providing copies of legal advice to third parties - ensure clear protocol in place - ideally a signed letter documenting the purpose of the disclosure and agreement by third party to keep advice confidential.
  • Advising alongside other professionals - beware multi-addressee emails.
  • Requests from regulators - regulators cannot force clients to disclose privileged material. Think very carefully before providing privileged material to a regulator e.g. tPR. If privileged material is provided, it should be on very specific terms. Be clear about what head of privilege applies.


  • Labelling - confidential and privileged.
  • Attendance notes - lawyers working papers will be privileged so allow lawyers to take the notes of meetings where the contents contain legal advice.
  • Training your employees - everyone needs to understand the risks, especially non-legal staff.
  • If in doubt, find out - privilege cannot be created after the event. Speak to your lawyers first to find out how communications can be framed to ensure they attract privilege.
  • Involve lawyers early in internal investigations - such investigations may involve tPR. Use of external lawyers or internal counsel may allow the company to claim privilege in such investigatory notes.


  • Client papers - notes on legal advice are likely to be disclosable.
  • Do not send on legal advice - advice should be shared with only the core team at the client.
  • Do not send advice on to third party e.g. actuary without first putting a protocol in place - think whether it is absolutely necessary for the advice to be shared.
  • Do not include legal advice in general commercial discussions.
  • Do not copy in lawyers – and assume that will automatically ensure that a communication is privileged.
  • Do not (or avoid) sending multi-addressee emails.
