Preserve Footage in 7–30 Days: Spoliation Letter for US Injury Claims

Learn when to send a spoliation letter in US injury claims, what to include, how to prove delivery, and the 7–30 day window to preserve footage.

Preserve Footage in 7–30 Days: Spoliation Letter for US Injury Claims

A spoliation letter is a written preservation notice that puts the recipient on formal notice to keep specific evidence relevant to a claim. Evidence like surveillance footage and event data recorder logs can disappear within days or weeks, so the letter should go out as soon as litigation is reasonably anticipated. Preserve your own records immediately and contact an attorney to send the notice before critical proof is gone.

TL;DR:

  • Sending a preservation letter should occur as soon as relevant evidence or custodians are identified, since evidence like surveillance footage can be overwritten within days.
  • Specificity in the letter, including precise descriptions of evidence categories, time frames, and exact locations, significantly increases the likelihood of compliance.
  • Certified mail, a process server, or documented email are the strongest methods to prove delivery of the preservation notice.
  • Courts can impose sanctions such as adverse inference instructions or case dismissal if evidence is lost due to failure to preserve following a formal notice.
  • Prompt legal action to preserve evidence enhances settlement leverage, especially if preservation failures are documented before trial.

What Is a Spoliation Letter and When Does the Duty Arise?

A spoliation letter, also called a preservation letter or a preservation of evidence notice, is a formal demand telling a person or organization to retain specific items relevant to a potential legal claim. Attorneys sometimes call the internal version a legal hold notice, though that term usually applies to a company’s own instructions to its staff rather than a demand sent to an outside party.

The legal duty to preserve evidence kicks in once litigation is “reasonably anticipated,” a standard that can be satisfied long before anyone files a lawsuit. According to the American Bar Association, that anticipation often begins the moment an accident or dispute occurs, not when a complaint gets filed months later.

  • Parties to the eventual case generally carry a stronger, more immediate preservation duty.
  • Non-parties (a property owner, a trucking company, a rideshare platform) may not owe the same automatic duty, which is exactly why a formal letter matters.
  • Both groups face consequences if they knew evidence mattered and destroyed it anyway.

Why Spoliation Letters Matter So Much in Personal-Injury Cases

Jurors tend to view destroyed evidence as an admission of guilt, and practitioners describe spoliation as one of the most damaging events that can happen to a case. The American Bar Association has gone as far as calling it “the kiss of death” for a client’s claim, since courts can instruct juries to assume the missing evidence would have hurt the party who lost it. In personal-injury claims, that missing evidence is often the most perishable kind: surveillance footage, black box data, and skid-mark photos that fade or get overwritten within days.

When Should You Send a Preservation Letter?

Send it the moment you can identify relevant evidence or the people holding it, not after your attorney has finished building the whole case. The “reasonably anticipated litigation” standard is an objective test. It asks whether a reasonable person in your position would expect a claim to follow, not whether a lawsuit has actually been filed.

Some evidence has a genuinely short shelf life:

  • Surveillance video at stores, apartment complexes, and parking garages often overwrites itself in 7 to 30 days.
  • Vehicle event data recorder logs can be lost after a vehicle is repaired, sold, or scrapped.
  • Cell phone location and text data get purged on carrier-specific retention schedules.
  • Dashcam and rideshare app data frequently cycles out within days of the trip.

The practical rule is simple: the moment you identify a custodian or a piece of perishable evidence, that is the moment to issue the letter. Waiting for a “better time” is how cases lose their strongest proof.

What Should a Spoliation Letter Include?

A vague or overbroad letter is a weak letter. According to LegalClarity, preservation letters work best when they name specific evidence categories and warn plainly about the consequences of noncompliance. Sample letters compiled by IAALS share a consistent structure that any effective letter should follow.

  1. Identify the parties and incident. State the date, location, and nature of the accident, plus the claim it relates to.
  2. List precise evidence categories with date ranges. Name surveillance systems, phone records, electronically stored information (often shortened to ESI), maintenance logs, and vehicle data, each with the specific window that matters.
  3. Instruct the recipient to suspend deletion. Tell them to halt routine purges, preserve original files or forensic images, and avoid any format conversion that could alter metadata.
  4. Request written confirmation. Ask the recipient to confirm in writing that preservation steps are underway.
  5. Warn of consequences and set a deadline. State that failure to preserve may lead to sanctions or an adverse inference, and give a reasonable but firm response window, often 10 to 14 days.

Pro Tip: Name the exact camera locations, file formats, or system names you want preserved. A letter that says “preserve all surveillance footage” is far easier to ignore than one that says “preserve footage from the north parking lot camera between 2:00 p.m. and 6:00 p.m. on the incident date.”

How Do You Send a Spoliation Letter and Prove It Was Delivered?

Certified mail with a return receipt, or service through a process server, creates a delivery record that is hard to dispute later. Email works fine as a supplement, but attorneys generally treat it as backup only, since a recipient can claim a message landed in spam or never arrived, according to the American Bar Association.

Keep everything: the mailing receipt, the tracking number, the signed green return card, and a copy of the letter itself. If the recipient acknowledges the letter by phone or email, document that exchange too. No confirmation within your stated deadline calls for a firm follow-up, not silence.

What Happens Legally When Evidence Is Lost or Destroyed?

Federal courts evaluate lost electronic evidence under Rule 37(e) of the Federal Rules of Civil Procedure, which asks whether a party took reasonable steps to preserve information that should have been kept for anticipated litigation, and whether the loss can be cured. The American Bar Association’s breakdown of Rule 37(e) explains that courts weigh both the loss itself and the intent behind it before deciding on a remedy.

Possible remedies scale with the severity of the conduct:

  • Curative measures, such as allowing a party to present evidence about the loss to the jury.
  • Adverse inference instructions, telling jurors they may assume the lost evidence was unfavorable to the party who lost it.
  • Exclusion of related evidence or testimony.
  • Monetary sanctions, covering the cost of the investigation or additional discovery.
  • Case-terminating sanctions, including dismissal or default judgment, reserved for the most severe cases.

Courts draw a sharp line between intentional destruction and honest negligence. Losing data by accident during a routine IT migration is treated far more leniently than deleting files after receiving a preservation letter. Intentional conduct can turn an ordinary discovery dispute into a case-ending sanction.

What Should You Do If You Receive a Spoliation Letter?

Receiving a preservation letter is not an accusation. It is a legal trigger that requires action, whether you are an individual, a small business, or a large company with records scattered across departments.

  1. Suspend routine deletion immediately. Pause auto-delete policies on email, cloud storage, and backup systems tied to the relevant time period.
  2. Put a litigation hold in place. Notify anyone who might hold relevant records, including counsel, IT staff, and records custodians.
  3. Identify custodians and data sources. Map out who has the evidence, whether it sits on a server, a phone, a dashcam, or a third-party cloud account.
  4. Document your preservation efforts. Keep a log of every step taken and every person notified.
  5. Respond in writing. If the letter’s scope seems overly broad, say so in writing rather than ignoring it outright; courts can narrow or shift the cost of disproportionate preservation demands when a party raises the issue properly.

Pro Tip: Never respond to a spoliation letter by simply deleting or “cleaning up” records before your attorney reviews them. That single move is the fastest way to convert a manageable discovery issue into an intentional spoliation finding.

How Do You Set Up an Internal Litigation Hold Notice?

A litigation hold notice is the internal instruction that tells your own employees, contractors, and IT staff to preserve records once you know litigation is likely, whether you sent the outside preservation letter or received one. Standard hold notices, as described in Practical Law’s model document, typically go out to anyone who might hold relevant paper files, emails, voicemails, video, cloud data, or device backups.

  • Scope statement: describe the incident and the categories of data covered.
  • Custodian list: name every employee or department likely to hold relevant records.
  • Data types: specify email, texts, cloud files, physical documents, and backups.
  • Acknowledgment request: ask each custodian to confirm in writing that they received and understood the hold.

Reissue the hold periodically for long-running cases, keep every signed acknowledgment on file, and loop in counsel before narrowing or lifting it.

Spoliation Letter vs. Litigation Hold Notice: What Is the Difference?

The two documents work as a pair, but they point in opposite directions. A spoliation letter is an external demand, sent from one party (or their attorney) to another party, a witness, or a third party who holds relevant evidence. Its job is to put an outside recipient on formal notice that specific evidence must be preserved for a claim that either exists or is reasonably anticipated.

A litigation hold notice is an internal instruction. A company’s own legal department sends it to its own employees, IT staff, and records custodians, telling them to stop routine deletion and preserve anything connected to the matter. You do not send a litigation hold to an opposing party, and you do not send a spoliation letter to your own staff.

The distinction matters for personal-injury claimants because both documents often need to exist at the same time on opposite sides of a case. If you are injured in a rideshare crash, your attorney sends a spoliation letter to the rideshare company demanding preservation of trip data and driver logs. The rideshare company’s legal team, in turn, issues its own internal litigation hold to its data engineers and dispatch staff so nobody deletes the very records your letter is asking them to keep.

Spoliation letter versus litigation hold comparison

Confusing the two can create real problems. A business that receives a spoliation letter but never issues its own internal hold is exposed, since an employee following an old auto-delete policy can still trigger sanctions against the company. Likewise, an individual who issues only an internal instruction to themselves, without a formal outside letter to the other party, has done nothing to legally bind that other party’s preservation duty. Both documents need to exist, addressed to the right audience, for preservation to actually hold up in court.

Best Practices for Drafting an Effective Spoliation Letter

Tone and clarity decide whether a letter gets taken seriously or gets ignored. The most effective letters read as firm and factual rather than aggressive. Threatening language without specifics tends to invite pushback from opposing counsel rather than compliance, while a letter grounded in exact dates, names, and evidence categories is far harder to dismiss.

Comprehensiveness matters more than length. A one-page letter that names the exact surveillance system, the exact date range, and the exact custodian will outperform a five-page letter full of generic legal boilerplate. Specificity forces the recipient to actually check what they have, rather than giving them room to claim they did not know what was being requested.

A few drafting habits separate strong letters from weak ones:

  • Lead with the facts of the incident, not legal argument. State the date, location, and parties involved before making any demand.
  • Use plain, direct verbs: “preserve,” “retain,” “suspend deletion.” Avoid vague phrases like “take appropriate action.”
  • Reference the legal basis briefly. A short mention of the duty to preserve once litigation is reasonably anticipated adds weight without turning the letter into a legal brief.
  • Set a real deadline, typically 10 to 14 days, and state what happens if the deadline passes without confirmation.
  • Request written acknowledgment, not just silent compliance, so you have proof the recipient received and understood the demand.

Sample letters from the New York City Bar illustrate how practitioners tailor this structure to the specifics of a given jurisdiction and case type, which is worth reviewing before drafting your own.

The “reasonably anticipated litigation” trigger is a nationwide baseline, but how courts apply it varies by state and by whether a case sits in federal or state court. Federal courts handling electronically stored information generally apply Rule 37(e) of the Federal Rules of Civil Procedure, which asks whether a party took reasonable steps to preserve and whether lost data can be restored or replaced through other means.

State courts, by contrast, often rely on their own common-law spoliation doctrines, and those doctrines differ meaningfully in what they require and what they allow as a remedy. Some states permit an independent tort claim for spoliation, letting an injured party sue separately over destroyed evidence. Others only allow spoliation to be raised as an evidentiary issue within the existing personal-injury case, through jury instructions or exclusion of evidence rather than a standalone lawsuit.

The strength of the required mental state also shifts by jurisdiction. Some states sanction a party only for intentional or bad-faith destruction, while others allow sanctions for ordinary negligence if the loss caused real prejudice to the other side. That gap matters enormously in personal-injury claims, where a defendant’s insurer or corporate legal team may argue that lost footage was an innocent IT error rather than deliberate concealment.

Because these standards vary so much by state, and because federal versus state jurisdiction can change which rule applies, a spoliation letter drafted for one type of case rarely transfers cleanly to another. An attorney familiar with the specific court and state where a claim will be filed is in the best position to calibrate the letter’s language, deadlines, and legal citations to match what that jurisdiction actually enforces.

How Spoliation Letters Influence Settlement Talks and Mediation

A well-documented preservation letter becomes leverage long before a case reaches trial. Insurance adjusters and defense attorneys know that a party who ignored a formal preservation demand faces real exposure to sanctions, and that knowledge shapes settlement math from the earliest conversations.

If a defendant’s team failed to preserve surveillance footage after receiving a clear, specific letter, plaintiff’s counsel can raise that failure during settlement negotiations as a factor pushing the case toward a stronger inference at trial. Even without a formal court ruling on spoliation yet, the mere possibility of an adverse inference instruction changes how a defense team values its own risk. Mediators, too, factor in preservation failures when helping parties gauge realistic outcomes, since a judge’s eventual ruling on missing evidence can swing a case’s value substantially.

The letter’s paper trail carries weight independent of the underlying facts of the accident. A signed return receipt, a documented follow-up, and a clear record of the recipient’s non-response tell a mediator that one side did everything right while the other side did not. That imbalance often accelerates settlement, since the party facing potential sanctions has strong incentive to resolve the case before a judge rules on spoliation and hands the other side an even stronger position.

Claimants sometimes underestimate this dynamic, assuming the letter only matters if the case goes to trial. In practice, the letter’s biggest value in many personal-injury claims shows up months earlier, at the negotiating table.

Why Early Preservation and Fast Attorney Contact Change Outcomes

Evidence that disappears in the first two weeks after a crash rarely comes back, and a case built on secondhand accounts settles for less than one backed by footage and data. Getting a preservation letter out fast protects both the strength of your claim and your leverage at the negotiating table, discussed above.
