The short version
- The duty to preserve arises on reasonable anticipation of litigation, not on service of a complaint. The Sedona Conference formulation is notice of a credible probability of litigation, serious contemplation of bringing it, or specific steps taken to commence it — so a demand letter arms the duty on both sides of it.
- Federal Rule of Civil Procedure 37(e) has two doors. Prejudice from lost electronically stored information gets curative measures no greater than necessary to cure it. Only a finding that the party acted with the intent to deprive unlocks an adverse-inference instruction, a presumption, dismissal or default.
- The routine operation of an auto-delete setting is not a defence once the duty has started. Retention rules on mailboxes, phones and chat tools, and disappearing-message features, have to be suspended for the people and topics in scope.
- Failing to issue a hold notice is not itself the violation. Courts ask what was actually lost, and Rule 37(e) asks only for reasonable steps — the 2015 committee note tells courts to be sensitive to a party's resources and sophistication.
Nothing in the federal rules tells a business to keep everything forever. They fix a moment after which losing things has consequences, then ask whether what you did after that moment was reasonable. Almost every fight about destroyed evidence is those two questions in that order, and the first is where small businesses lose.
The trigger is anticipation, not service
The duty to preserve is a common-law duty, not written into the Federal Rules of Civil Procedure — which is why people looking for a rule number never find one. The Sedona Conference states the test in the form most courts work from: a reasonable anticipation of litigation arises when an organisation is on notice of a credible probability that it will become involved in litigation, seriously contemplates initiating litigation, or takes specific actions to commence litigation.
Read the second and third limbs again: they point at the person thinking about suing, not the person being sued. Sending a demand letter does not start a clock only against the recipient — it is good evidence that the sender seriously contemplates litigation, and their own files come under the duty from that moment.
How firm does the anticipation have to be
No duty yet
Fact-dependent
Duty has started
The Seventh Circuit worked this ground in 2025. In Pable v. Chicago Transit Authority, decided 28 July 2025, the plaintiff contacted attorneys about his termination on 29 October 2018 and deleted his entire Signal thread with a colleague four days later. He did not sue for another year. The district court found his duty to preserve had been triggered before the deletion, and the court of appeals held that was not clear error. Four days of contact with a lawyer was enough.
What the notice says, and who has to receive it
A hold notice is an internal instruction to stop the normal disposal of information. It has no statutory form. What makes one effective is that people can act on it without a second conversation.
What an effective hold notice does
- Describes the dispute in terms the recipient recognises, and the subjects and date range in scope
- Says what preservation actually requires of them, not just that they must preserve
- Names one person who answers questions about it
- Names the auto-delete and disposal functions that must be suspended, and who suspends them
- Asks for an acknowledgement that it was received, read and understood
- Is reissued as a reminder, and amended when the scope changes
It goes to more people than the ones named in the dispute: the custodians who hold the documents, whoever administers the systems, and third parties holding your data on contract — the bookkeeper, the IT provider, the cloud platform, each of whom needs their own short compliance notice. A hold that never reaches the person who can switch off the retention rule is a hold in name only.
The duty does not stop at your email server
Scope is decided by Rule 34's phrase possession, custody, or control, not by what feels like company property. Laptops, the work phone, the shared drive, the accounting system and the chat workspace are obviously in. So are the tools people actually used, which in most small businesses means text messages and a group chat rather than email.
Two facts decide whether a device is in scope
Who owns the device or account?
Was it used for the work now in dispute?
No
Yes
The business
Out of scope
A company account nobody used for this matter. There is no duty to freeze the whole estate.
Plainly yours to preserve
Work email, the shared drive, the chat workspace, the job-management system. Suspend disposal here first.
An individual
Leave it alone
A private phone with nothing on it. Sweeping in personal data you do not need creates its own problem.
The contested corner
An employee's own phone carrying work messages. Control is fact-specific — but if the owner of the business is the custodian, the argument is not available.
For an owner-managed business that cell mostly collapses: the company cannot say it lacks control over the director's phone when the director is the company. The question worth asking is narrower — which accounts did we run this job through, and who else was on them.
Auto-delete is where a small business actually loses
The 2015 committee note to Rule 37(e) is explicit that routine operation is not a shield: the prospect of litigation may call for reasonable steps to preserve information by intervening in that routine operation. Nobody has to decide to destroy anything. The settings do it.
The ones that catch people are ordinary consumer defaults. On an iPhone, Settings › Apps › Messages › Keep Messages offers 30 Days, 1 Year or Forever, and Apple warns that anything other than Forever removes conversations and their attachments automatically once the period elapses — and that with Messages in iCloud on, deleting on one device deletes across all of them. Chat platforms carry workspace retention rules an administrator set once and forgot. Signal and WhatsApp both offer disappearing messages per conversation.
That last feature was the second half of the Pable case. About a year after the first deletion, on 29 October 2019, he switched on Signal's disappearing-messages feature for the same thread, which then deleted messages twenty-four hours after they were read. The pattern is established: in NuVasive v. Kormanis (M.D.N.C. 2019) a defendant was held to have been obliged to disable the automated destruction feature on his own phone.
Put the preservation demand in writing
The same duty binds the other side, and it only bites once they are on notice. A short written preservation notice, naming the accounts and the date range you expect to be kept, costs nothing and fixes their trigger date in writing.
Rule 37(e) has two doors, and only one ends the case
The rule bites where information that should have been preserved is lost because a party failed to take reasonable steps, and it cannot be restored or replaced through additional discovery. That last condition does quiet work: if the thread survives on the other participant's phone or in a backup, there is usually nothing to sanction.
What the finding on intent changes
The information is gone and cannot be restored. Did the party act with the intent to deprive the other side of its use?
No — but the loss caused prejudice
Rule 37(e)(1). Measures no greater than necessary to cure the prejudice: further discovery at your cost, the other side's fees for the motion, evidence at trial about how the material was lost.
Yes — intent to deprive is found
Rule 37(e)(2). The court may presume the lost information was unfavourable, instruct the jury that it may or must presume so, or dismiss the action or enter default judgment. No separate finding of prejudice is required.
The numbers in Pable show what the right-hand door costs. The complaint was dismissed with prejudice while still in discovery, $75,175.42 was awarded under Rule 37(e) and split equally between the client and his lawyer, and the lawyer alone paid a further $53,388 under 28 U.S.C. § 1927 and $21,367 under Rule 37(a)(5). The claim never reached its merits.
A hold is not permission to sit on documents
Two mirror-image mistakes follow the notice. The first is treating a hold as a shield: it changes what you may delete, not what you must hand over, and it makes nothing privileged. The second is issuing it and then doing nothing — one court sanctioned a defendant whose counsel neglected to oversee the process after perfunctorily issuing a hold (Franklin v. Howard Brown Health Center, N.D. Ill. 2018). Monitoring compliance is part of the obligation.
There is a criminal edge that has nothing to do with Rule 37. Under 18 U.S.C. § 1519, knowingly destroying or concealing a record with intent to impede the investigation or proper administration of a matter within the jurisdiction of a federal agency — including in relation to or contemplation of such a matter — carries up to twenty years. On 26 January 2024 the FTC and the DOJ Antitrust Division updated their standard preservation letters and compulsory process to address collaboration tools and ephemeral messaging explicitly.
Releasing the hold
A hold that is never lifted stops being a legal instrument and becomes an accidental retention policy. Data you no longer need is data you will one day have to search, produce, or explain a breach of. The release is a real step: confirm the duty has ended, cross-check the custodians and systems against every other live matter so you do not strip preservation from something a second dispute still needs, then tell everyone who received the original notice — including the IT provider and any third parties — that it is lifted.
The judgement call is when the duty ends, and it is later than people assume. Not at the handshake, but when the settlement is executed, releases exchanged and any appeal window closed — and not at all if the same facts could support a claim by someone who has not sued yet. A limitation period still running on a related claim is a reason to keep the hold, not to lift it.
The whole discipline reduces to something a business owner can do in an afternoon: fix the date the duty started and write it down, list the accounts and devices the disputed work ran through, switch off the settings that delete on them, tell the handful of people involved in one email, and keep a note of what you did and when. It is not the elaborate exercise the literature implies. What makes it urgent is that the cheap version only works if it happens in the first week — and the thing that starts that week is usually a letter nobody thought was serious.

Frequently asked
When does the duty to preserve documents actually begin?
When litigation is reasonably anticipated, which is normally well before a complaint arrives. The widely used formulation is notice of a credible probability of becoming involved in litigation, serious contemplation of bringing a claim, or specific steps taken to commence one. A demand letter, a formal internal complaint, a government inquiry or a serious incident can all be enough, depending on the circumstances.
Does the duty apply to me if I am the one threatening to sue?
Yes, and often earlier than to the other side. Seeking legal advice about a claim, sending a cease-and-desist letter or deciding to bring an action have all been treated as triggering the duty. In a 2025 Seventh Circuit case the plaintiff's duty was found to have started when he contacted attorneys about his termination — four days before he deleted the messages, and a year before he filed suit.
Do I have to preserve text messages and chat on my personal phone?
If the phone carries messages about the matter in dispute, in practice yes. Courts have divided over whether an employer legally controls an employee's personal device, and a bring-your-own-device policy has been held not to confer that control. But the individual custodian can be subpoenaed directly, and where the business owner is the custodian the distinction disappears entirely.
What happens if I already deleted something before I knew about the claim?
Often nothing. Rule 37(e) only engages where the information cannot be restored or replaced through additional discovery, so material sitting in a backup, an archive or the other participant's phone is not lost. Deleted items also survive for a grace period in most systems. Retrieve what you can, disclose what happened, and do not improvise an explanation.
When can a litigation hold be released?
When the preservation duty has genuinely ended — the matter resolved, releases exchanged and any appeal window closed — and not before. Cross-check the custodians and systems against other live or foreseeable matters first, because one release can strip preservation from data a second dispute still needs. Then notify everyone who received the original notice, including IT and outside providers, and resume ordinary disposal.
