How to Respond to a Demand Letter: A Calm, Step-by-Step Plan

What should you do first when you receive a demand letter?

Read the whole letter once without replying, then write down three things: who sent it, what they say you owe or must do, and the date they want an answer by. Those three facts decide everything that follows.

1. Note the sender. A letter from an individual, from a business, from an attorney and from a debt collector each call for slightly different handling.
2. Mark the deadline on your calendar. A sender's deadline is not a court deadline, but missing it can lead the sender to file.
3. Keep everything. Save contracts, invoices, texts, emails, photos and payment records. Turn off any auto-delete settings on messages that touch the dispute.
4. Do not call to argue. A heated phone call creates no record of what was offered and can produce statements you later regret.
5. Check your insurance. Homeowner, renter, auto and business policies may cover some claims, as explained below.
6. Decide on a response date. Even a short note saying you are reviewing the letter and will reply by a set date keeps the conversation in writing.

If the letter comes from a collection agency, federal and state debt collection laws give you extra rights. Our guide on how to respond to a collection letter covers those.

Is a demand letter the same as being sued?

No. A demand letter is a private request. A regular civil lawsuit starts when a complaint is filed with a court and you are served with a summons, which directs you to file a written response within 30 days after service (Code of Civil Procedure section 412.20). Some cases run on other clocks: an eviction summons allows 10 court days (section 1167), and a small claims case gives you a trial date rather than a written-response deadline. Once you are served, the court's timeline controls, whatever any letter says.

Some letters still carry legal weight. In a few situations, a written demand is a step the sender takes before suing, or one that sets up extra damages or special rules:

Could your insurance cover the claim?

Possibly, so check before you reply. Claims about injuries at your home, a car accident, damage you caused to someone's property or, for a business, an injured customer can fall within liability coverage. Sending the claim to your insurer and asking it to respond is called tendering the claim.

• Find every policy that might apply: homeowner or renter, auto, umbrella, commercial general liability and professional liability.
• Read each policy's conditions for any requirement to give prompt notice of a claim and any limit on payments or promises you make without the insurer's consent.
• Send the insurer a copy of the demand letter in writing and keep proof of when you sent it.
• Ask for a claim number and the name of the adjuster, and tell the sender who is handling the claim.

A demand about unpaid invoices or a broken contract may fall outside liability coverage, but the policy language decides that, not the label on the letter.

How do you decide whether the demand is valid?

Test the letter against your own records, line by line. A useful working file answers these questions:

• Does the sender have the facts right: dates, amounts, what was promised and what was delivered?
• Does a contract or invoice support the amount, including any interest, late fees or attorney fee clause?
• Do you have your own claim against the sender, such as defective work, overbilling or an unpaid refund?
• Is the claim old? Lawsuits have filing deadlines, and a claim past its deadline may be defensible on that ground alone.
• Is part of the claim fair even if the total is not?

Example (hypothetical): a homeowner receives a $4,800 demand from a painter for the balance of a job. She has photos showing two rooms were never finished and a text from the painter promising to return. Her records point to a partial dispute: she owes something, but not the full balance. That conclusion shapes a response offering a specific lower amount with the photos attached.

What are your options for responding?

You have four realistic choices, and each has trade-offs you should weigh against your facts.

If you pay anything, use a traceable method and write on the payment, or in a cover letter, what it is for. If a lawyer prepared the release, read it fully before signing, and consider having your own lawyer look at it.

Can your settlement offer be used against you?

Generally not to prove liability. California Evidence Code section 1152 makes an offer to compromise, and statements made while negotiating it, inadmissible to prove that you are liable for the loss. Section 1154 gives the same protection to the other side: their offer to accept less cannot be used to prove their claim is invalid.

The protection has limits. Section 1152 does not cover partial payment of a claim without disputing it, and a debtor's payment or promise to pay a preexisting debt can be used to show a new or revived duty to pay. Statements made outside settlement negotiations, such as an earlier text admitting a mistake, are not covered by section 1152. Labeling a letter as a settlement communication signals your intent, but the statute, not the label, decides what is protected.

If you run a business: the CLRA 30-day correction window

A consumer who plans to sue for damages under the Consumers Legal Remedies Act must first send the business a written notice, by certified or registered mail, describing the alleged violations and demanding a fix, at least 30 days before filing (Civil Code section 1782(a)).

If the business gives, or agrees to give within a reasonable time, an appropriate correction, repair, replacement or other remedy within 30 days after receiving the notice, the consumer cannot maintain an individual damages action under the act (section 1782(b)). Class actions follow separate conditions in section 1782(c), and a claim for injunctive relief can be filed without the notice.

Section 1782(e) adds a useful protection: attempts to comply are treated as an offer to compromise under Evidence Code section 1152, and are not an admission that the business broke the law. Count the 30 days from the date the notice arrived.

What to say, and not say, in your written response

Keep the reply to one page where you can. State your position, the facts that support it and what you propose. Leave out insults, guesses about the sender's motives and threats of your own.

• Do confirm the deadline you are working to, or propose a new one.
• Do attach the key documents rather than describing them.
• Do not admit facts you have not checked against your records.
• Do not promise payment you cannot make on time.

When an attorney-written response makes sense

If the amount is modest and your records answer the claim point by point, a short reply in your own words may be all the situation needs. An attorney-written response is worth considering when the demand comes from a lawyer, cites statutes you are unsure about, involves a large amount or a consumer law notice, or when you want your settlement offer framed so it stays protected.

Through Talk to My Lawyer, a licensed California attorney writes your response letter from the demand you received and your own documents, sets out your position and any offer, and sends it on your behalf. To decide whether to pay, fight or settle, talk to a lawyer about your facts.
