Preservation of Evidence Letter (Litigation Hold)
Before you can prove your case, the proof has to survive. I draft and send attorney preservation-of-evidence letters on firm letterhead that put the other side on written notice to preserve video footage, emails, texts, documents, devices, and records before they can be deleted or overwritten. Flat fee, sent certified mail plus email.

It scopes your matter and recommends the right package: the $575 attorney preservation / litigation-hold letter, or the $1,500 pre-litigation negotiation phase if the dispute is already in motion.

One attorney preservation / litigation-hold letter on firm letterhead, USPS certified mail (signature requested) plus email delivery, up to two client revision rounds before sending, and review of the other side's first substantive response with a short next-step recommendation. Subpoenas, court orders, filing, and multi-round negotiation are not included; multi-round negotiation is the $1,500 Pre-Litigation Negotiation Phase.
No. It is a formal notice, not a subpoena or court order, and I will not pretend otherwise. Its power is what it sets up: once the other side is on dated, written, certified-mail notice, "we deleted it in the ordinary course" stops being a clean excuse. Courts can respond to destruction after notice with a range of remedies, up to adverse-inference instructions or default in serious federal ESI cases involving intent to deprive (FRCP 37(e)(2)). If evidence is at genuine risk of imminent destruction, a court order is the stronger tool, and that is a separate, quoted engagement.
As early as possible: as soon as a real dispute exists or litigation is realistically on the table, and before or together with any demand letter. Surveillance footage, chat messages, and call recordings often sit on short automatic deletion cycles, sometimes days or weeks. The letter should reach the people who control that evidence before the cycle runs.
A first draft is usually 3 to 5 business days after I receive the necessary documents. Rush 24 to 48 hour turnaround may be available for an added fee, and preservation letters are often exactly the matters where rush makes sense. Flag any overwrite or deletion deadline in your intake.
After you hire me: who the other side is (and any third parties holding evidence, like a landlord with camera footage), a short timeline of the dispute, the categories of evidence you believe they hold, any deletion deadlines you know of, and copies of prior correspondence. I turn that into the letter's preservation demands.
The natural next phase when the dispute moves past a single letter: additional counter-letters, written settlement negotiations through settlement or impasse, strategy updates, and draft, review, or revision of one settlement agreement or mutual release. It is triggered when the other side engages, counsel appears, or a settlement needs papering.

Evidence on a deletion cycle? Start the intake now
A few short questions: who holds the evidence, what kind it is, and any deadline you know of. I respond with a recommended scope and next-step plan. No call required.
A preservation of evidence letter (also called a litigation-hold? letter or spoliation letter) is a formal attorney notice to an opposing party, or to a third party holding evidence, that says three things: a dispute exists or is reasonably anticipated, here are the specific categories of evidence you control that relate to it, and you are now on notice to preserve them, including suspending any automatic deletion.
The letter does not ask the other side for money and does not argue the merits. It does one narrow job extremely well: it creates a dated, delivered, written record that the recipient knew litigation was coming and knew what to preserve. That record is the foundation of every spoliation? argument you may need later.
What I typically demand preservation of, tailored to your matter. Tap any card for the detail.
Documents, files, and business records
Contracts, invoices, personnel files, accounting records, inspection reports, maintenance logs, policies in force at the time.
Tap for detail ↻The letter identifies the record categories by subject and date range so "we could not tell what you wanted" is off the table. For businesses, it also demands suspension of routine document-destruction schedules for anything within scope.
Tap to flip back ↻Surveillance footage, dashcams, recordings
CCTV, doorbell and body cameras, dashcams, recorded calls. Often the single most valuable and most perishable evidence.
Tap for detail ↻Many camera systems overwrite on rolling cycles that can be measured in days or weeks. The letter demands immediate segregation and retention of footage for the relevant dates, times, and camera locations, and asks for written confirmation that it has been pulled.
Tap to flip back ↻Emails, texts, chat logs, server data, devices
Email accounts, text threads, Slack and chat platforms, server and access logs, databases, social media, phones and laptops, vehicle data.
Tap for detail ↻ESI? is where federal spoliation law has real teeth (FRCP 37(e)). The letter demands suspension of auto-delete settings and retention policies, preservation of metadata, and no wiping, reimaging, or disposal of identified devices.
Tap to flip back ↻Evidence held by someone who is not your opponent
The gas station whose camera caught the crash. The building manager with keycard logs. The former employer with the personnel file.
Tap for detail ↻Third parties usually have no stake in your dispute and no reason to keep anything. A polite, specific attorney letter often gets footage pulled and saved the same week, because cooperating is easier than being subpoenaed later. Each additional recipient is scoped in your intake.
Tap to flip back ↻A party's duty to preserve evidence does not wait for a lawsuit to be filed. In general, it arises when litigation is reasonably anticipated or foreseeable. The problem is proving, later, exactly when the other side should have known. A preservation letter removes the guesswork: from the date of delivery, they knew, because a lawyer told them in writing and a certified-mail receipt proves it arrived.
Beyond adverse-inference instructions, courts have a range of responses to spoliation depending on the forum, the severity, and the prejudice: evidentiary rulings, exclusion of testimony, monetary sanctions, and in serious cases terminating sanctions. I do not promise any of these outcomes; what the letter does is put your future self in the strongest position to ask for them. For a deeper plain-language walkthrough of what to save on your own side, see my evidence preservation guide.
The short answer: as early as possible. The letter is cheap insurance against a problem that is impossible to fix later. The common trigger points:
Right after the incident
Accidents, injuries, thefts, altercations, terminations. Surveillance footage and access logs are at their most perishable in the first days.
When the dispute becomes real
They stopped paying, denied the claim, or repudiated the deal. If you can picture yourself suing, the evidence needs to be locked down now.
Before or with a demand letter
A demand letter tells them a claim is coming, which is exactly when careless (or worse) deletion happens. Preserve first, or send both together.
The moment you suspect deletion
If you have any indication they are already scrubbing, the letter should go out immediately, and I flag whether stronger tools are warranted.
What it does instead is change the price of deletion. Ignoring a certified attorney letter and destroying evidence anyway is how a defensible case becomes an indefensible one: the notice record is what courts look at when deciding whether destruction was innocent or sanctionable. That is the honest trade: the letter is far cheaper and faster than court process, and its power is contingent on a court enforcing consequences later.
When the letter is not enough:
- Evidence at imminent risk from a bad actor: a court order (for example a temporary restraining order directed at preservation) is the stronger tool. That is a separate, quoted engagement, and I tell you plainly when I think your facts call for it.
- You need the evidence in hand, not just preserved: getting copies compelled from an unwilling party requires discovery tools that only exist inside a filed case or arbitration: subpoenas, document requests, depositions.
- The evidence is already gone: no letter resurrects it. The fight becomes proving when it was destroyed and what the destroyer knew, which is exactly why sending the letter early matters so much.
Once you have paid and the conflict check clears, I send you a short structured request. I call it the Evidence Vault: one organized submission that lets me draft a letter specific enough that the other side cannot claim confusion about what to keep. You do not need any of this before hiring me; the intake takes a few minutes and the Vault comes after.
- Who holds the evidence. The opposing party, plus any third parties: the business with the cameras, the platform with the messages, the employer with the files. Each recipient gets a tailored letter, scoped in the engagement.
- What they hold. Categories, not exhibits: "loading-dock camera footage for June 3-5," "emails between your dispatcher and my client, May through July," "the delivery van's telematics data." I turn your plain description into preservation demands.
- The timeline. A short chronology of the dispute with dates. This anchors the date ranges in the letter.
- Any deadline you know of. Camera overwrite cycles, retention settings, a device about to be returned or wiped. This drives whether rush turnaround is warranted.
- Prior correspondence. Anything already exchanged with the other side, so the letter is consistent with the record and does not contradict something you already said.
What is a preservation of evidence letter?
A formal written notice from an attorney telling an opposing party or a third party that a dispute exists or is reasonably anticipated, identifying the categories of evidence they hold (documents, video footage, emails, texts, server logs, devices, records), and demanding that they preserve that evidence rather than delete, overwrite, or alter it. It is also called a litigation-hold letter or spoliation letter. Its core product is a dated paper trail proving the recipient was on notice.
Is it legally binding? Can it force them to preserve evidence?
No letter can physically force anyone to preserve anything, and I will not tell you otherwise. It is a notice, not a subpoena or court order. Its power is what it sets up: once a party is on written notice, destroying relevant evidence stops looking like routine housekeeping. In federal court, Rule 37(e) allows curative measures for lost ESI and, on a finding of intent to deprive, adverse-inference instructions or even default. In California, Evidence Code section 413 lets the trier of fact consider willful suppression of evidence.
When should I send one?
As early as possible: as soon as a real dispute exists or litigation is realistically on the table, and before or together with any demand letter. Much of the most valuable evidence sits on short automatic deletion cycles, sometimes days or weeks for surveillance footage and chat messages. Every day of delay is evidence you may never get back.
What happens if they destroy evidence after getting the letter?
It depends on the forum and the facts, and no outcome is guaranteed. Courts can respond with evidentiary and monetary sanctions, adverse-inference instructions, and in serious federal ESI cases involving intent to deprive, dismissal or default under Rule 37(e)(2). In California, willful suppression can be weighed against the destroying party under Evidence Code section 413, and willfully destroying evidence about to be produced in a legal proceeding can be a misdemeanor under Penal Code section 135. The letter is what makes those arguments available, because it proves notice.
What is included in the $575 flat fee?
A single attorney preservation / litigation-hold letter on firm letterhead, USPS certified mail with signature requested plus email delivery, up to two client revision rounds before sending, and review of the other side's first substantive response with a short next-step recommendation. Not included: subpoenas, court orders, filing, discovery motions, forensic collection, multi-round negotiation, and settlement work. Multi-round negotiation and settlement work are the $1,500 Pre-Litigation Negotiation Phase; letters to additional recipients are scoped in the engagement.
Do I need a preservation letter, a demand letter, or both?
They do different jobs. A demand letter asks for money or action and tries to resolve the dispute; a preservation letter protects the proof you would need if it does not resolve. In many matters the right move is both, either combined in one letter or sent as preservation first, quickly, then the demand once the record is secured. I recommend the sequence based on your facts during intake.
Can you send one outside California?
Case-by-case. A preservation letter is a pre-litigation communication, not a court filing, so I can often send one nationwide, tailored to the recipient's jurisdiction. Filing a complaint, seeking a court order, or appearing as counsel of record requires bar admission in the relevant state; for California matters I handle the full pre-litigation cycle directly.
Do I have to preserve my own evidence too?
Yes. The duty to preserve runs both ways. Once you reasonably anticipate litigation, deleting your own texts, emails, or files about the dispute can expose you to the same spoliation consequences you want to use against the other side. After you hire me I give you a short list of what to stop deleting on your side.
Evidence only gets more deleted. Lock it down now.
Flat-fee phases, no hourly meter inside the package. Start with the letter; escalate only if the dispute does.
