A spoliation of evidence letter, more precisely called an evidence preservation letter, is a written notice demanding that a person or company preserve specific evidence relevant to a dispute. Sending or receiving one creates a legal duty to preserve, and destroying covered evidence afterward can trigger court sanctions, including adverse jury instructions. If you suspect a claim is coming, the right move is to preserve everything relevant now and get an attorney involved before evidence disappears.
TL;DR:
- Sending a preservation letter after an incident ensures a clear, detailed record of evidence types, custodians, and retention instructions, which prevents unintentional destruction.
- The duty to preserve evidence begins once litigation is reasonably foreseeable, often before a formal lawsuit, especially when routine deletion schedules are involved.
- Failing to preserve electronically stored information can lead to court-ordered remedies like adverse-inference instructions, evidence exclusion, or even case dismissal in cases of intentional spoliation.
- Responding to a preservation letter by documenting all steps taken and consulting legal counsel is crucial to avoid accusations of bad faith or intentional evidence destruction.
- Early evidence preservation, coordinated with legal advice, enhances settlement leverage and strengthens the case by making the difference between winning and losing depend on surviving key documents.

What Is a Spoliation of Evidence Letter and When Should You Send One?
A preservation letter formally puts a person, business, or insurer on notice that litigation is pending or reasonably foreseeable, which creates a legal duty to preserve specified evidence and paper files tied to the dispute. Once that duty attaches, routine housekeeping is no longer an excuse. Courts generally look at the totality of circumstances to decide whether a party should have known litigation was coming, not just whether a lawsuit was actually filed.
You typically send or receive one of these letters after:
- A car, truck, or motorcycle accident where vehicle data or dashcam footage exists
- A formal injury claim or demand letter has been submitted to an insurer
- A subpoena or discovery request has been issued
- An internal investigation begins after a workplace or premises injury
A preservation letter is not a court order. It is a private demand, though ignoring it can carry real consequences once litigation formally begins. A judge’s preservation order, by contrast, carries the court’s direct authority and its own enforcement mechanisms.
What to Include in a Spoliation Letter: A Drafting Checklist
Vague demands invite vague compliance. A letter that says “preserve everything” gives a recipient’s IT department nothing to act on and gives opposing counsel room to argue later that they did not know what was actually required. Focused preservation demands that name specific custodians, systems, and date ranges are far more enforceable than broad ones.
A solid letter covers:
- A clear description of the incident and the claims it relates to
- A defined date range for the evidence sought
- Named custodians (specific employees, departments, or vehicle operators)
- The systems and evidence types involved: email servers, cloud storage, telematics, physical items
- An explicit instruction to suspend automatic deletion and routine overwrites
- A directive to preserve backups and archived copies, not just live files
- Instructions for securing physical evidence, tagged and stored intact
- A request that the recipient document every preservation step taken
Sample preservation-letter language published by IAALS illustrates how this specificity gets phrased in practice:
That kind of language leaves little room for a recipient to claim confusion about scope.
What Types of Evidence Should a Preservation Letter Cover?
The evidence worth naming depends on the case, but personal injury and commercial disputes tend to draw from the same categories:
- Physical evidence: vehicles, damaged equipment, clothing, or defective products, tagged and stored without alteration
- Paper records: incident reports, medical records, inspection logs, maintenance files
- Electronically stored information (ESI): email, cloud files, internal databases, backup servers, and even ephemeral messaging apps that auto-delete by default
- System and device logs: telematics data, black box recorders, IoT sensor logs, and app usage records
- Surveillance and communications: security camera footage, dashcam video, and phone records
A commercial truck crash is a good illustration of why this list matters. Electronic logging devices, GPS telematics, and driver qualification files often exist for only a limited retention window before a company’s system cycles them out, which is one reason preserving evidence in trucking cases has to happen fast. Chain of custody matters here too. Evidence that changes hands without documentation loses credibility even when it survives.
When Does the Duty to Preserve Kick In?
Courts do not wait for a lawsuit to be filed before recognizing a preservation duty. The standard is whether litigation was pending or reasonably foreseeable, judged by the totality of the circumstances surrounding the incident and the parties’ conduct afterward.

Here is where most spoliation problems actually start: a company’s routine retention policy automatically deletes footage, emails, or logs on a set schedule, and nobody pauses that schedule once a claim becomes likely. Courts often distinguish between deletion that happened before any notice, which may be defensible, and deletion that happened after notice, which is not.
Immediate steps once you suspect a claim is coming:
- Notify IT or records staff that a hold is required
- Suspend auto-deletion and any scheduled overwrite of relevant systems
- Identify and preserve backups, not just active files
- Name the custodians whose files and devices need protection
- Document every step taken, including dates and who was notified
Pro Tip: Keep a simple, dated log every time you take a preservation step. Courts weigh good-faith preservation efforts heavily, and a written record showing you acted promptly is often more persuasive than any argument your attorney makes after the fact.
What Happens if Evidence Is Destroyed After a Preservation Letter?
Under Federal Rule of Civil Procedure 37(e), lost electronically stored information triggers a two-tier framework. If ESI that should have been preserved is lost and cannot be restored, a court can order measures no greater than necessary to cure the resulting prejudice. If the court finds the party acted with intent to deprive another side of the information, it can go further: adverse jury instructions, exclusion of evidence, or in extreme cases, dismissal or default judgment.
Remedies courts commonly use include:
- Additional discovery to compensate for what was lost
- Cost-shifting or fee awards against the party responsible
- Preclusion of related evidence or arguments
- Adverse-inference instructions telling the jury it may assume the missing evidence was unfavorable
- Dismissal of claims or entry of default judgment in cases of bad faith
State law adds its own layer. Virginia’s spoliation statute directs courts to impose sanctions no greater than necessary to cure prejudice, while allowing more severe remedies, including adverse inferences or dismissal, when the loss resulted from intentional or reckless conduct. The ABA has described spoliation as frequently “the kiss of death” for a case, since juries tend to assume the worst when evidence that should exist simply does not. Sanctions are not automatic or uniform. Judges tailor them to the actual prejudice caused, which is exactly why documenting intent, or the absence of it, matters so much on both sides.
You Received a Preservation Letter: What Now?
Getting a spoliation letter is not an accusation of wrongdoing. It is a notice that puts you on the clock, and how you respond in the following days can shape your exposure for the life of the case.
- Preserve everything named in the letter immediately, even before consulting counsel
- Identify every custodian whose files, devices, or records might be relevant, and notify them directly
- Suspend any automatic deletion, backup rotation, or overwrite process touching those systems
- Document each preservation step, including who was notified and when
- Consult an attorney before deleting, discarding, or altering anything connected to the incident
If relevant evidence was already deleted before the letter arrived, do not panic and do not try to reconstruct or alter what remains. Instead, gather your retention policy documentation and a timeline showing the deletion followed routine, pre-existing schedules rather than a deliberate response to the claim. That timeline is often the difference between a finding of ordinary negligence and one of intentional spoliation.
Pro Tip: If your company has a document retention policy, print or export a dated copy of it the moment you receive a preservation letter. It becomes your primary evidence that any prior deletion was routine, not retaliatory.
How Preservation Letters Shape Settlement Negotiations
A preservation letter does more than protect evidence. It creates a documented paper trail showing the other side was on notice, which becomes relevant leverage if evidence later goes missing.
- A well-documented preservation letter strengthens a sanctions argument if the opposing party fails to comply
- Raising spoliation allegations can pressure a defendant toward earlier settlement, though courts scrutinize these claims and tailor remedies to actual prejudice, not just the accusation
- Preservation strategy should be coordinated with negotiation timing so a hold does not get treated as a bad-faith litigation tactic
Used correctly, the letter becomes a quiet form of leverage that rewards early, deliberate action over reactive scrambling.
How Tyler Injury Law Handles Preservation Holds
Tyler Injury Law focuses on personal injury claims including car, motorcycle, and truck accidents, dog bites, and premises liability, and preservation strategy is built into intake from day one. The firm’s approach to case preparation and negotiation centers on maximizing recovery, which starts with locking down evidence before it disappears, a discipline reflected in outcomes such as a $3.25 million recovery in a commercial trucking case. In practice, that means sending preservation letters early, coordinating with IT and forensic vendors on data holds, building a written chain of custody, and using that documentation directly in motions when evidence is at risk.
Why Evidence Preservation Decides More Cases Than People Expect
Cases rarely turn on a dramatic piece of evidence. More often they turn on whether ordinary evidence, a maintenance log, a dashcam clip, a set of texts, survived long enough to matter. The firms and clients who send preservation letters within days of an incident consistently end up with stronger negotiating positions than those who wait for a lawsuit to force the issue. Waiting is the single most avoidable mistake in this entire process. Act early, document everything, and let the paper trail do the arguing later.

Get Help Preserving Evidence Before It Disappears
Retention schedules do not pause themselves, and insurance adjusters are not going to remind you that dashcam footage or maintenance logs are about to cycle out of a company’s servers. The firm operates on a contingency-fee basis, meaning there is no upfront cost to get a preservation letter drafted and sent while evidence still exists.

On intake, the firm typically moves fast: drafting and sending the preservation letter, coordinating a forensic hold with IT or third-party vendors, and building a documented chain of custody from day one, supporting stronger settlement leverage later. Whether your case involves a pedestrian accident or a motorcycle collision, the preservation window is often measured in days, not months. Request a free case review now, and get evidence locked down before a retention policy erases it for good.

FAQ
How Serious Is Spoliation of Evidence?
It can be serious enough to decide a case outright. Courts can impose adverse-inference instructions, exclude evidence, or in extreme cases involving intentional conduct, dismiss claims or enter default judgment.
What Is an Example of Evidence Spoliation?
A common example is a trucking company allowing its telematics or dashcam data to auto-delete on a routine schedule after receiving a preservation letter about a crash, destroying evidence that should have been held.
Who Can Send a Spoliation Letter?
Anyone with a legitimate interest in a dispute can send one, including injured parties, their attorneys, or insurers, though letters carry the most legal weight when drafted by counsel with specific custodians and systems named.
Is Spoliation of Evidence a Crime?
Spoliation is typically addressed through civil sanctions rather than criminal charges, but destroying evidence with intent to obstruct an official proceeding can, in some circumstances, expose a person to separate criminal liability.
