A letter from a lawyer, usually called a demand letter, tells you that someone believes you owe them money, need to stop doing something, or have caused them harm, and it warns that a lawsuit may follow if you don’t respond. To respond to a lawyer letter, verify the sender is a real attorney, read the demand carefully, preserve every related document, notify any insurer that might cover the claim, decide whether you need your own lawyer, and send a written reply by a trackable method before the deadline. The steps below walk through each of those in the order they matter.
Confirm the Letter Actually Came From a Lawyer
Scammers send threatening letters on fake letterhead to pressure people into paying debts that don’t exist. The Office of the Comptroller of the Currency lists common warning signs: demands for immediate payment by wire transfer, prepaid cards, or gift cards, threats of arrest, and refusal to provide written verification of the debt.1Office of the Comptroller of the Currency.

Every state maintains a searchable directory of licensed attorneys, and the American Bar Association links to each one.2American Bar Association. Lawyer Licensing Search the sender’s name. If the attorney doesn’t appear, or shows a suspended or inactive license, treat the letter as suspect. If it references a debt you don’t recognize, federal law lets you request written verification before paying anything.
Read Exactly What Is Being Demanded
Once you know the letter is real, read it slowly and pull out four things: who is making the claim, what they say you did, what legal theory they’re using (breach of contract, negligence, an intellectual property dispute, an unpaid debt, or something else), and what they actually want. The demand might be a specific dollar amount, an order to stop a particular activity, the return of property, or a combination.
Then find the deadline. Most demand letters give you between 10 and 30 days. That deadline is set by the sender rather than a court, so missing it doesn’t trigger automatic legal consequences, but ignoring it often prompts the other side to file suit immediately. Don’t skim. If a phrase or legal term is unclear, write it down and ask a lawyer.
Preserve Every Document Connected to the Dispute
The moment the letter arrives, stop discarding anything that could be relevant. Keep the letter and its envelope, along with contracts, emails, text messages, invoices, receipts, photographs, and any other records tied to what happened. Turn off auto-delete on relevant email and messaging accounts. Back up texts and save voicemails.
This is not optional housekeeping. Once you’re on notice of a credible threat of litigation, courts expect routine destruction of documents to stop. Federal courts have sanctioned parties who destroyed evidence by entering default judgments, barring them from contesting certain facts, giving adverse jury instructions, and imposing monetary fines.3United States District Court for the District of Nebraska. Litigation Holds: Ten Tips in Ten Minutes Hang on to everything until the matter is fully resolved.
While you’re gathering material, build a timeline. Write down what happened and when, note which document supports each event, and list any witnesses with their contact information. Memories fade quickly, and this record will anchor whatever response you send.
Call Your Insurance Company Before You Do Anything Else
This is the step people skip most often, and it can be the costliest mistake in the process. If the letter involves a car accident, an injury on your property, a professional services dispute, or almost any claim that you caused someone harm, your auto, homeowner’s, renter’s, or professional liability policy may cover it.
Most policies require you to notify the insurer “promptly” or within a specific window after you learn of a potential claim. Late notice can be grounds for the insurer to deny coverage entirely, leaving you personally on the hook for the full amount. If the claim is covered, the insurer will typically assign you a defense attorney at no cost and handle negotiations directly.
Report the claim even if you’re not sure it’s covered. Let the insurer make that call. Reporting something that turns out not to be covered costs you nothing meaningful; failing to report something that was covered can be catastrophic.
Decide Whether You Need Your Own Attorney
Not every demand letter requires one. If someone wants $500 for a broken fence and you agree the claim is fair, you can resolve it yourself. Several situations, though, are worth the cost of a consultation:
- The amount at stake is significant. If the demand runs to thousands of dollars, a consultation fee is small compared to what a bad response can cost you.
- The legal theory is complex. Contract, intellectual property, and employment claims involve nuances that are easy to get wrong.
- The letter threatens a specific lawsuit date. You need someone who can evaluate the claim’s strength and prepare a defense.
- You can’t tell if the claim has merit. An attorney can usually tell you in one meeting whether the other side has a real case or is bluffing.
Initial consultations typically run between $180 and $565 per hour depending on the area and the attorney’s experience. Some lawyers offer a flat-fee review for demand letters. Early legal advice is often the most cost-effective spending you can do, because mistakes made in the first response are hard to undo.
Choose How to Respond
With the claim understood and your evidence organized, you have four realistic options:
- Comply. If the claim is valid and the amount is reasonable, paying or doing what’s asked is often the fastest and cheapest route, especially when fighting would cost more than the demand.
- Negotiate. If the claim has some merit but the demand is excessive, counter. Most demand letters open high expecting negotiation, and this is where most disputes settle.
- Deny. If the allegations are wrong or the legal theory is weak, refuse clearly and explain why, backed by your evidence.
- Ignore it. Almost always the wrong call. Silence tells the other side you’re not taking the matter seriously and makes a lawsuit more likely. The only time it makes sense is when an attorney has reviewed the letter and told you the claim is baseless and the sender unlikely to follow through.
A response can combine options. You might deny part of the claim while offering to settle the portion that has merit. The point is to choose deliberately rather than let the deadline pass.
Draft the Reply Without Admitting Fault
Keep the tone professional. Angry or sarcastic responses feel satisfying to write and terrible to explain to a judge. Acknowledge that you received the letter, note its date, and state your position: you dispute the claim, you’re proposing a settlement, or you’re agreeing to the demand. Do not, in acknowledging receipt, concede any of the allegations.
The single most important rule is to avoid any language that reads as accepting blame. Phrases like “I’m sorry this happened” or “I should have handled this differently” can be used against you later. Stick to facts and leave opinions out.
How Settlement Language Is Protected
If you’re proposing a compromise, Federal Rule of Evidence 408 generally prevents settlement offers and statements made during negotiations from being used in court to prove liability or the amount of a claim.4Legal Information Institute. Federal Rules of Evidence Rule 408 – Compromise Offers and Negotiations The protection exists so people can negotiate honestly. It has limits, though. Courts can still admit settlement-related evidence for other purposes, such as showing bias or obstruction of a criminal investigation, and Rule 408 is federal; state versions vary. Have an attorney review the language before you send a substantial offer.
Send It So You Can Prove Delivery
Use a method that documents delivery. USPS Certified Mail with return receipt requested is the standard. The return receipt records the recipient’s name, the delivery date, and a signature.5United States Postal Service. What is Proof of Delivery Keep a copy of everything you send, along with the certified mail receipt and tracking number. If the dispute reaches court, you’ll need to prove what you sent and when.
A Demand Letter Is Not a Lawsuit
Confusing the two is common and dangerous. A demand letter is a request from another party’s lawyer. It carries no court authority, and while ignoring it is unwise, no court-imposed deadline is running.
A lawsuit starts when you’re served with a summons and complaint. That summons comes with a court deadline to file a formal answer. In federal court, you generally have 21 days from the date you’re served.6Legal Information Institute. Federal Rules of Civil Procedure Rule 12 – Defenses and Objections: When and How Presented State courts set their own, often between 20 and 30 days. Miss it and the court can enter a default judgment, meaning the other side wins without having to prove anything.
If what arrives is a summons and complaint rather than a demand letter, call a lawyer the same day. Responding to a lawsuit requires formal pleadings filed with the court, and the mistakes are often irreversible.
