A notice of intent to destroy evidence is a formal written warning — usually sent by a lawyer or an opposing party — that specific documents, data, or physical items in someone’s possession relate to a legal dispute and must not be deleted, altered, or thrown away. If you have received one, your obligation to preserve the listed materials is active now, and failing to comply can lead to monetary sanctions, an adverse ruling, loss of the case, or in some circumstances a federal prison sentence of up to 20 years.
What the Notice Is and What It Isn’t
Despite the alarming language these letters sometimes use, the notice is not itself a lawsuit. It is a formal statement that litigation is either underway or expected, and that you hold information the sender considers relevant. The letter identifies categories of evidence you need to protect: emails, text messages, contracts, financial records, photographs, social media posts, surveillance footage, physical objects, and anything else the sender flags. Its purpose is to freeze the status quo so nothing disappears before the formal discovery phase of litigation, when both sides exchange evidence.
The letter also serves a strategic function for whoever sent it. By putting you on written notice, the other side makes it much harder for you to later claim you didn’t know the materials mattered. If evidence goes missing after the letter arrives, a court will have little sympathy for an argument that the loss was accidental or routine.
When Your Duty to Preserve Actually Begins
Here is the part that catches people off guard: your legal obligation to preserve evidence does not start when the letter arrives. It starts earlier. Under the federal rules governing litigation, the duty arises as soon as you reasonably anticipate that a lawsuit could happen. That is an objective standard. A court asks whether a reasonable person in your position would have foreseen litigation, not whether you personally expected it.
Common triggers include a complaint from a customer, learning about an accident involving your product, a demand letter from an attorney, or notice of a government investigation. The written notice is simply the most explicit confirmation that the duty has kicked in, or that it should have kicked in already.
This matters because if a court later finds you should have been preserving evidence before the letter arrived and you weren’t, the letter won’t save you. The duty runs from the moment litigation became foreseeable, regardless of what paperwork you had or hadn’t received.
First Steps After the Letter Arrives
Treat the notice as urgent. The first thing to do is acknowledge receipt in writing. A brief response confirming you got the demand and intend to comply creates a documented record that protects you. You don’t need to admit fault or agree with every claim in the letter. Confirm you received it and are taking it seriously.
Then read it carefully and identify exactly what evidence it covers. Preservation demands range from narrow requests for specific emails between two people to sweeping demands covering every digital file in an organization. Understanding the scope tells you what you need to locate and protect. If the letter is vague or unreasonably broad, that’s a conversation to have with an attorney. The default position while you figure it out is to preserve, not delete.
Consult a lawyer before responding in detail. An attorney can evaluate whether the demand is reasonable in scope, advise on what counts as relevant evidence, and draft a response that protects your interests without over-committing or under-complying.
Putting a Litigation Hold in Place
The core action required is a litigation hold: a formal internal directive, typically written, that suspends any routine process that could delete, overwrite, or destroy relevant information. Once litigation is reasonably anticipated, a party must stop routine document destruction and put a hold in place to ensure relevant materials survive.
In practice, the hold involves several concrete steps:
- Identify custodians. Figure out which employees, contractors, and executives are likely to have relevant documents or data. These people need to be notified directly.
- Send written hold notices. Each custodian should get a clear written instruction explaining what to preserve, why, and that nothing potentially relevant may be deleted. Use plain language that both the IT manager and the sales rep can follow.
- Disable auto-deletion. Coordinate with IT to turn off automated systems that purge old emails, overwrite backup tapes, or cycle through stored data on a schedule. These routine processes are the most common way evidence gets destroyed unintentionally.
- Secure physical evidence. If the matter involves tangible items such as a defective product, printed contracts, or personnel files, move them to a controlled location where they cannot be lost, altered, or discarded.
- Back up electronic data. For key custodians, create forensic or backup copies of relevant files, email accounts, and messaging apps. This protects against both accidental deletion and hardware failure.
Document the collection process carefully. Keep records of who collected the data, when, how it was stored, and every person who handled it afterward. This chain of custody establishes that the evidence is authentic and hasn’t been tampered with. If the chain breaks down, the other side can challenge the evidence as unreliable, which may lead a court to exclude it.
How Much to Preserve, and for How Long
You do not have to preserve every file your organization has ever created. Courts expect preservation to be reasonable and proportional to the dispute. The scope depends on the nature of the claims, how accessible the data is, and the cost and burden of preserving it relative to the value of the case. The goal is to protect genuinely relevant information, not to freeze an entire operation.
When in doubt, err on the side of keeping too much rather than too little. A court is unlikely to punish you for preserving more than necessary, but it will absolutely punish you for preserving too little. If a category is borderline relevant, preserve it and let your attorney argue scope later.
The hold stays in place until the matter is fully resolved, whether through settlement, final judgment, or the point at which litigation is no longer reasonably anticipated. Do not lift a hold just because things have been quiet for a few months. The duty survives as long as the underlying dispute does. Before releasing any held materials, confirm with counsel that all related claims, appeals, and regulatory obligations have concluded.
Civil Penalties for Failing to Preserve
Spoliation is the legal term for destroying, altering, or failing to preserve evidence, and it carries serious civil consequences. Federal courts draw a sharp distinction between two levels of culpability, and the penalties scale accordingly.
Evidence Lost Without Intent to Deprive
If electronically stored information that should have been preserved is lost because you failed to take reasonable steps to protect it, and the information can’t be recovered through other means, a court can order measures designed to cure the harm. The remedy can be no greater than necessary to fix the prejudice caused by the loss. That might mean additional discovery for the other side, costs related to recovering the data from alternative sources, or a curative jury instruction.
Evidence Destroyed With Intent to Deprive
When a court finds you acted with the intent to deprive the other side of evidence, far harsher sanctions become available. Under Federal Rule of Civil Procedure 37(e)(2), a court may presume the destroyed information was unfavorable to you, instruct the jury to assume it would have hurt your case, or dismiss your claims or enter a default judgment against you entirely.
The “intent to deprive” threshold is critical. The federal rules were amended specifically to prevent courts from imposing these severe sanctions based on mere negligence. Carelessness can still get you sanctioned under the proportional-cure provision, but the case-ending penalties require something more deliberate.
Courts also retain inherent authority to address spoliation that threatens the integrity of proceedings, which generally requires a finding of bad faith. The sanctions available through that channel can be just as severe, and they are not limited to electronically stored information the way Rule 37(e) is, so spoliation of physical evidence can be addressed this way as well.
When Destroying Evidence Becomes a Federal Crime
Civil sanctions are not the ceiling. Destroying evidence can be a federal crime under two main statutes, and both carry substantial prison time.
Under 18 U.S.C. § 1519, anyone who knowingly destroys, alters, conceals, or falsifies any record or tangible object with the intent to obstruct a federal investigation or any matter within the jurisdiction of a federal agency faces up to 20 years in prison. The statute, enacted as part of the Sarbanes-Oxley Act, is broad. It covers documents, digital files, and physical objects, and it does not require that a formal proceeding already be underway.
Separately, 18 U.S.C. § 1512(c) makes it a crime to corruptly alter, destroy, or conceal any record or object with the intent to impair its availability for use in an official proceeding. The maximum penalty is also 20 years. This statute focuses on obstruction of official proceedings and has been applied in cases ranging from corporate fraud to public corruption.
These criminal provisions apply to individuals, not just organizations. An employee who shreds documents or wipes a hard drive on instructions from a supervisor can face personal criminal liability, and so can the supervisor who gave the order.
If You Suspect the Other Side Plans to Destroy Evidence
The same type of notice can also run in the opposite direction. If you have learned, through a letter, a conversation, or suspicious behavior, that the opposing party intends to destroy evidence relevant to your case, the playbook is different from responding to one aimed at you.
Send your own preservation demand immediately. The letter should identify the categories of evidence you need preserved, state the factual and legal basis for the dispute, and make clear that destruction of the identified materials will be treated as spoliation. That creates a paper trail proving the other side was on notice.
If destruction appears imminent or already underway, you can ask the court for emergency relief. A motion for a temporary restraining order or preliminary injunction can compel the other party to preserve evidence while the case is pending. Courts take these requests seriously when there is credible evidence that spoliation is likely, and they can order materials produced for forensic imaging or independent custody.
Document everything you can about the evidence at risk: who has it, what form it is in, and any communications suggesting it might be destroyed. If the evidence does disappear, this documentation supports a later request for spoliation sanctions. And if the destruction appears deliberate and involves a federal matter, the criminal statutes above may give you additional leverage.
Mistakes That Make Things Worse
Handling the notice is straightforward in theory, but people routinely make the same errors. The biggest one is doing nothing. Hoping the situation goes away or assuming the letter is a bluff virtually guarantees a worse outcome. Courts treat inaction after receiving a preservation demand as evidence that you didn’t take your obligations seriously.
The second most common mistake is implementing a hold on paper but failing to follow through. Sending a companywide email saying “don’t delete anything” and then never checking whether anyone complied is barely better than doing nothing. Courts expect affirmative steps: disabling auto-deletion, confirming with key custodians, creating backup copies. Not just a memo.
A third mistake is responding to the notice with hostility or making admissions you don’t need to make. Acknowledge receipt, confirm you are taking steps to comply, and say nothing else until you have spoken with an attorney. The letter is not an invitation to litigate the merits of the underlying claim in writing.
Finally, people underestimate how much electronically stored information exists. Text messages, Slack conversations, voicemails, cloud storage, draft documents, and metadata can all be relevant and all be discoverable. A hold that covers email but ignores messaging apps or personal devices used for work leaves gaps the other side will find.
