Reasonable Steps to Preserve Privilege: Clawback and Rule 502(d) Orders

To preserve privilege after an inadvertent disclosure, you need to satisfy all three prongs of Federal Rule of Evidence 502(b): the production was unintentional, your pre-production review was reasonable, and you moved quickly to claw the material back once you learned about it. Taking reasonable steps to preserve privilege after an inadvertent disclosure is less about any single heroic action and more about building a record a court can look at and call careful. Miss any prong and the privilege can be ruled waived.¹

The Three Prongs Courts Apply

Rule 502(b) treats a disclosure as non-waiving in any federal or state proceeding when the disclosure was inadvertent, the privilege holder took reasonable steps to prevent disclosure, and the privilege holder promptly took reasonable steps to correct the error, including following the procedures in Federal Rule of Civil Procedure 26(b)(5)(B) when applicable.¹

Each prong is tested on its own. A state-of-the-art review process will not save you if you sat on the mistake for weeks after learning about it. Lightning-fast notification will not save you if you had no review system at all. Courts weigh the reasonableness of precautions, the time taken to rectify the error, the scope of discovery, the extent of disclosure, and the overriding issue of fairness.¹ No single factor controls the outcome, which leaves judges with real discretion.

What Counts as a Reasonable Pre-Production Review

The second prong is where most privilege-recovery efforts succeed or fail. Courts look at the full picture of how you ran the review, not any one tool or step.²

Volume and time pressure. A production of two million documents under a tight court-imposed deadline gets more leeway than a production of 500 documents with months to prepare. Courts factor in both the scope of discovery and any time constraints.
Review procedures used. A documented, multi-step process carries weight: keyword searches, followed by attorney review, followed by a quality-control pass by senior lawyers. A single-pass review by contract attorneys with no supervision is harder to defend.
Ratio of errors to total production. Three privileged documents slipping through in a production of 50,000 looks very different from 300 out of 5,000. A low error rate relative to volume strengthens the reasonableness argument.
Pre-existing records management. A company that tags communications with outside counsel in its document management system is in a better position than one that dumps everything into a shared drive.

Keyword searches remain the most common first pass, using terms like “privileged,” “counsel,” “legal,” and attorney names to catch obvious candidates. They miss documents that discuss legal strategy without using those exact words. Predictive coding adds a second layer: reviewers code a sample set as privileged or not, and a machine-learning algorithm scores the remaining documents by likelihood of privilege so the highest-risk material is prioritized for human review. The value is catching what keywords miss, such as a memo that reflects attorney mental impressions without ever using the word “legal.”

The use of advanced analytical tools, including predictive coding and linguistic analysis software, can support a finding of reasonableness.³ The technology alone is not enough. Courts want to see testing and validation. Running a keyword search once and calling it done will not hold up. Sample the output, check for false negatives, adjust the terms, and document every step. That documentation becomes your evidence if the opposing party later argues you were careless.

Moving Quickly Once You Spot the Disclosure

The clock on the third prong starts the moment someone on your team realizes that privileged material ended up in a production. Internal tracking systems that log which batches were produced, when, and what review each batch received let you identify the specific files quickly instead of re-reviewing the whole production from scratch.

Verify before you demand. Confirm that each document actually qualifies as a privileged communication or work product. A panicked demand to return non-privileged material damages credibility and makes courts skeptical of future claims. Check whether the document involves legal advice, litigation strategy, or mental impressions prepared in anticipation of trial. A document merely copied to a lawyer that contains no legal substance will likely fail a privilege claim.

The Clawback Notice

Once you confirm the problem, notify the other side in writing. The notice is what triggers the receiving party’s obligations under FRCP 26(b)(5)(B) and is the primary evidence a court looks at when deciding whether you acted promptly under the third prong.¹

The notice should identify the specific documents at issue, typically by Bates number or production volume. State the basis for the privilege claim for each document, whether attorney-client privilege or work-product protection. If a pre-trial clawback agreement or court order is in place, follow the procedure it requires. A vague demand that fails to identify which documents are at issue gives the receiving party grounds to push back.

Within a short period after the notice, provide a privilege log for the claimed documents, describing each one without revealing the privileged content. If only part of a document is privileged, provide a redacted version that strips the protected portions while leaving the rest available.⁴ Timing is measured in days, not weeks. Every day of delay is a data point the opposing party will use to argue you were not taking the privilege seriously.

What Happens on the Other Side

Once the receiving party gets a proper clawback notice, FRCP 26(b)(5)(B) imposes immediate obligations. The receiving party must promptly return, sequester, or destroy the specified information and any copies. They cannot use or disclose the information until the privilege claim is resolved. If they already shared the material with someone else before the notice, they must take reasonable steps to retrieve it.⁵

Sequestration means what it says. The receiving party cannot keep reviewing the documents while deciding whether to challenge the claim. Notes, summaries, and analyses derived from the material should also be set aside. On your side, preserve the original information until the claim is resolved. Do not delete your copy thinking the problem is gone once the other side returns theirs.⁵

The receiving party does not have to accept the demand. They may promptly present the information to the court under seal for a ruling on whether the privilege claim is valid.⁵ That is the only proper channel. If the court sides with you, the material stays out. If not, it goes back into the case.

Lock In Protection With a Rule 502(d) Order

The strongest form of protection available is a court order under Rule 502(d). A federal court can order that any disclosure connected with the pending litigation does not waive privilege, and that protection extends to every other federal or state proceeding as well.¹ If a 502(d) order is in place, privileged documents that slip into a production must be returned regardless of how careful or careless the producing party was in its review. The order eliminates the need to satisfy the “reasonable steps” test under 502(b) for purposes of the covered litigation.

This is the most underused tool in large-scale discovery. A 502(d) order lets parties produce faster because they do not need to conduct an exhaustive privilege review before every production. If something privileged gets through, the clawback mechanism kicks in. For cases involving millions of documents, this can save substantial time and money on front-end review.

A private agreement under Rule 502(e) is a weaker version. Two sides can agree that inadvertent production will not waive privilege, but the agreement binds only the parties to it. A non-party, such as a government agency or a litigant in a separate lawsuit, is not bound by a 502(e) agreement.¹ For the protection to follow the documents everywhere, incorporate the agreement into a court order under 502(d). A clawback agreement that is not court-ordered may be worthless in the very situation where you need it most.

Boundaries Worth Knowing

An inadvertent disclosure does not open the door to every related privileged communication. Rule 502(a) treats intentional disclosures as capable of producing a broader subject matter waiver, but only when the waiver is intentional, the disclosed and undisclosed materials concern the same subject matter, and fairness requires they be considered together. The Advisory Committee Note states explicitly that an inadvertent disclosure cannot result in a subject matter waiver.¹ An accidental production of one memo about a patent strategy does not entitle the other side to every privileged document on patents.

One more thing works in your favor on the receiving side. ABA Model Rule 4.4(b) requires a lawyer who receives a document relating to the representation of their client, and who knows or reasonably should know that it was inadvertently sent, to promptly notify the sender. The duty also covers metadata embedded in electronic files.⁶ State rules vary on whether the receiving attorney must do more than notify, so check the local version of Rule 4.4 in the jurisdiction where the case is pending.
