A preservation letter (sometimes called a “spoliation letter”) is a formal notice telling a person, company, or agency to keep specific items and data that could matter in a case. It puts the recipient on clear notice that destruction, alteration, or routine overwriting of evidence is unacceptable—and that courts can impose penalties if it happens. Because the burden of proof sits with the injured party, securing records early can make the difference between speculation and a fact-driven recovery.
When Should a Preservation Letter Be Sent—and To Whom?
As soon as you reasonably anticipate a personal injury claim, preservation duties begin. That means the letter should go out promptly—often within days of the incident—so routine deletion policies don’t erase critical footage, logs, or device data. Recipients typically include the at-fault driver or operator, their employer, any contractors involved, property owners, insurers or third-party administrators, and—when appropriate—government agencies that hold 911 audio, traffic-signal data, or bodycam footage. Your letter should be specific about the incident, the categories of material to preserve, and the expectation that normal retention schedules be suspended. Speed matters because the statute of limitations clock is running even while you gather proof.
What Should a Preservation Letter Cover?
- Identify the incident and time window. Provide the date, approximate time, and location, and request preservation for a reasonable buffer before and after the incident so context isn’t lost.
- List specific data sources and formats. Name camera systems, telematics, vehicle modules, phone logs, dispatch platforms, access-control logs, maintenance software, and cloud backups. Ask that native files, metadata, and audit trails be preserved in place.
- Call out physical items. Request that vehicles, machinery, damaged components, and packaging be secured without repair or alteration. In product cases, this can preserve potential product liability claims by keeping the failure mode intact for inspection.
- Suspend auto-deletion and overwrites. Instruct recipients to halt recycling on DVRs, email retention tools, messaging apps, and SaaS platforms tied to the incident. Confirm who is responsible for compliance.
- Request notice before any change. Require prompt written notice if equipment must be moved, opened, or decommissioned, so your expert can observe or participate.
What Happens If the Recipient Ignores the Letter?
Courts can impose remedies when a party fails to preserve relevant material after receiving proper notice. Depending on the facts, judges may order additional discovery, shift costs, instruct the jury to presume missing evidence would have been unfavorable (an “adverse inference”), or impose sanctions. These issues are folded into the broader litigation process, where your attorney documents the request, proves control and relevance, and shows prejudice from the loss. A well-drafted letter—sent early to all custodians—maximizes your leverage if spoliation of evidence becomes an issue.
Practical Tips Before You Send One
Draft narrowly but thoroughly: overbroad demands invite pushback, but vague requests miss what matters. Use clear categories, ask for native formats and metadata, and name specific systems by brand/model when you can. Send the letter by trackable means (and email, if available), keep proof of delivery, and calendar follow-ups. Finally, align your request with the elements you must prove—liability, causation, and damages—so you are preserving what you’ll truly need at summary judgment or trial.
