Privilege That Holds Up In-House

The core principle, stated once

The attorney-client privilege protects a confidential communication made for the purpose of obtaining or giving legal advice. That is the whole test, and three things fall outside it: business advice, the underlying facts, and documents that exist independent of any request for counsel. A fact does not become privileged because you told it to a lawyer, and a lawyer’s involvement does not convert a business decision into a legal one. For in-house counsel — who sit in operational meetings, approve deals, and weigh in on strategy — the recurring problem is not knowing the rule but applying it to communications that genuinely carry both purposes.

Separate legal advice from business advice

When a single communication serves both a legal and a business purpose, most courts apply a primary-purpose analysis: was obtaining or giving legal advice the dominant reason for the communication, or merely one of several? Some courts ask instead whether legal advice was a primary purpose. The framing varies by jurisdiction and is worth confirming against the current rule in your forum. Either way, the practical defense is the same — make the legal purpose visible and severable.

• When you are giving legal advice, say so, and frame the analysis in legal terms — risk, exposure, compliance, contractual obligation — rather than purely commercial ones.
• Where practical, keep legal advice in its own communication rather than burying two sentences of analysis inside a long operational email.
• If you are acting in a business capacity — negotiating, approving spend, setting strategy — recognize that those communications are likely discoverable, and write them accordingly.

Upjohn warnings in interviews

When counsel interviews employees during an internal investigation, the privilege belongs to the company, not the employee. Before the substance, give the employee what is commonly called an Upjohn warning: you represent the company, not them individually; the conversation is privileged, but the privilege is the company’s to assert or waive; and they should keep the discussion confidential. The point is to foreclose a later claim that the employee believed you were their personal lawyer — a misunderstanding that can compromise both the privilege and the employee’s cooperation. Many in-house teams find it useful to script the warning and record that it was given.

The over-designation trap

The most common in-house mistake is trying to manufacture privilege by routing business communications through a lawyer — copying the GC on an operational email, or stamping “Privileged & Confidential” on documents that contain no legal advice. It does not work. Courts look at the substance, not the cc line or the header, and a business email does not become privileged because a lawyer received it.

The deeper cost is to the claims that matter. A privilege log padded with plainly non-privileged entries invites a challenge to the whole log, and a court that finds reflexive over-designation may order broad review — putting the genuinely privileged communications at risk along with the rest. Reserve the label for what fits it.

Control distribution — and know the waiver traps

Privilege protects confidential communications, and confidentiality erodes with circulation. Keep distribution to those who need the legal advice to do their jobs. The recurring waiver traps:

• Forwarding privileged material to anyone outside the privilege — auditors, consultants, business partners, or recipients beyond the board and its committees — generally waives.
• Sharing legal advice with public-relations firms or other outside vendors, absent a structure designed to preserve protection.
• Partial disclosure that waives the whole subject. Voluntarily disclosing part of a privileged communication — or affirmatively relying on advice of counsel as a defense — can waive privilege over the entire subject matter, not just the piece you chose to reveal.

Work product is a separate, broader protection

Material prepared in anticipation of litigation — by or for counsel — carries work-product protection, which is distinct from privilege and in some respects broader. It can reach facts and the analysis of non-lawyers working at counsel’s direction, and it is harder to waive by disclosure to aligned parties. Two practical notes: protection turns on litigation being reasonably anticipated, not merely possible, so a document created in the ordinary course of business does not qualify simply because litigation later arrives; and opinion work product — counsel’s mental impressions and legal theories — receives the strongest protection of all. When the prospect of a dispute becomes concrete, that is the moment to be deliberate about what gets created and how.

Quick reference

A note on cross-border limits

In-house counsel privilege is not universal. Some jurisdictions — including in EU competition proceedings and in a number of civil-law systems — do not extend privilege to in-house lawyers at all, or limit it to admitted outside counsel. Before relying on privilege for communications that touch a foreign jurisdiction or could be examined by a foreign regulator, confirm the rule in that forum rather than assuming the protection you have at home travels with the document.
