Consumer Fraud: The 30-Day Demand Letter

One of the main laws behind consumer fraud claims in California is the Consumers Legal Remedies Act, the law that lists more than two dozen unfair or deceptive practices in sales and leases of goods and services to consumers (Civil Code 1770). The Act lets a consumer recover actual damages, punitive damages and attorney's fees, but it puts one condition in front of a damages claim: a written notice and demand, mailed the right way, at least 30 days before the lawsuit is filed.

This guide explains what the letter must say, how it must be sent, what happens when the business answers, and when you can go to court without waiting. The notice is a strict rule. The Judicial Council's jury instruction on it, CACI 4701, tells jurors the consumer "must have complied exactly" with the notice requirements.

How does the 30-day notice work, step by step?

Identify the practice. Match what the business did to one or more of the practices listed in Civil Code 1770(a), such as claiming a product has benefits it does not have, or advertising a price that leaves out mandatory fees.
Write the notice. The letter must tell the business the particular violations of section 1770 you are claiming and demand that it correct, repair, replace or otherwise rectify the goods or services (Civil Code 1782(a)).
Mail it correctly. Send it by certified or registered mail, return receipt requested, to the place where the transaction happened or to the business's principal place of business in California (Civil Code 1782(a)).
Wait at least 30 days. The damages lawsuit may be filed no sooner than 30 days after the notice (Civil Code 1782(a)).
Read the response. If the business gives, or agrees to give within a reasonable time, an appropriate correction, repair, replacement or other remedy within 30 days of receiving the notice, an individual damages claim under the Act cannot be maintained (Civil Code 1782(b)).
File, if needed. If there is no appropriate remedy, the damages claim may be filed, generally within three years of the practice (Civil Code 1783).

What must the letter say, and how must it be sent?

Requirement	What the law says	Source
Timing	Thirty days or more before an action for damages is commenced	Civil Code 1782(a)
Content: the violations	Notify the business of the particular alleged violations of section 1770	Civil Code 1782(a)(1)
Content: the demand	Demand that the business correct, repair, replace or otherwise rectify the goods or services	Civil Code 1782(a)(2)
Form	In writing	Civil Code 1782(a)
Delivery	Certified or registered mail, return receipt requested	Civil Code 1782(a)
Address	The place where the transaction occurred, or the principal place of business within California	Civil Code 1782(a)
Proof at trial	The consumer must prove the notice was given and must have complied exactly	CACI 4701

An email, a text message, a phone call or a complaint to a store manager does not meet the statute's terms, because the Act names the delivery method. A letter that only says "you cheated me" is also weak, because the statute asks for the particular violations. Naming the specific paragraphs of section 1770 and describing the facts behind each one is the safer approach.

What happens after the business receives the letter?

The 30-day window is designed for settlement. A decision the Judicial Council cites under CACI 4701 says the clear intent of the Act is to provide and facilitate precomplaint settlements of consumer actions wherever possible. Three rules shape what happens next.

An appropriate remedy ends the damages claim under the Act. If, within 30 days after receipt, the business gives or agrees to give an appropriate correction, repair, replacement or other remedy within a reasonable time, no damages action may be maintained under section 1780 for that individual consumer (Civil Code 1782(b)). Whether an offer is "appropriate" can itself be disputed.

The business's response cannot be used as an admission. Attempts to comply with a demand are treated as an offer to compromise, are inadmissible under Evidence Code 1152, and are not an admission that the business broke the law. The business may, however, use its own response to show good faith or compliance (Civil Code 1782(e)).

An honest error can be a defense. No damages may be awarded if the business proves the violation was not intentional, resulted from a bona fide error despite reasonable procedures to avoid it, and was corrected under section 1782 (Civil Code 1784; CACI 4710).

Can I go to court without waiting 30 days?

Yes, for some relief. A lawsuit asking only for an order that stops the practice, called injunctive relief, may be filed under section 1770 without first sending the notice. Not less than 30 days after filing, and after sending the notice, the consumer may amend the complaint without the court's permission to add a request for damages (Civil Code 1782(d)). The same correction rules then apply.

The notice rule is also specific to the Act. The Act says its remedies are in addition to remedies under other laws (Civil Code 1752), and a decision the Judicial Council cites under CACI 4700 says a reasonable correction offer does not prevent the consumer from pursuing other statutory or common law claims. A claim under the Unfair Competition Law or the False Advertising Law, explained in our guide on what counts as false advertising and what you can recover, follows its own rules. So does a fraud claim. Each of those laws has its own deadline, set out in how long you have to bring a consumer fraud claim.

What changes the answer?

A class action. When the letter raises a class grievance, the business must do much more to avoid a damages class action: identify similarly situated consumers, notify them, give the remedy they request, and stop the practice (Civil Code 1782(c)).

The consumer is a senior or a person with a disability. The notice rule is the same, but the damages claim can include an additional award of up to $5,000 when the jury makes certain findings (Civil Code 1780(b)). Our guide on extra protections for seniors in consumer fraud cases explains those findings.

The purchase was not a consumer purchase. The Act covers goods and services bought or leased for personal, family or household purposes (Civil Code 1761(a), (b) and (d)). A decision the Judicial Council cites under CACI 4700 held that a mortgage loan is neither a good nor a service under the Act, so some financial transactions fall outside it.

The business made an unintentional error. The bona fide error defense in Civil Code 1784 applies only if the business also makes the correction the statute requires.

The deadline is close. The three-year period for a claim under section 1770 runs from the date of the practice itself (Civil Code 1783), and the notice must go out at least 30 days before filing. Section 1782(d) lets a consumer file for injunctive relief without the notice and add damages later; whether a later amendment counts as timely is worth raising with a lawyer before relying on it.

What could this look like? An example

For example, imagine a Petaluma homeowner who buys a water filtration system after a salesperson says it removes a contaminant that, according to the manufacturer's own specification sheet, it does not filter. The homeowner learns the truth two months later from a water test. That is a representation that goods have benefits they do not have, one of the practices listed in Civil Code 1770(a)(5).

The homeowner writes a letter naming that paragraph, describing the salesperson's statement and the test result, and demanding a refund and removal of the system. The letter goes by certified mail, return receipt requested, to the dealer's showroom where the sale took place. On day 25, the dealer offers a partial credit toward a different system. If that offer is not an appropriate remedy, the homeowner may file a damages claim after the 30 days pass, along with any fraud or Unfair Competition Law claims, and the dealer's offer cannot be used as an admission. If the dealer had instead refunded the full price and removed the system, the damages claim under the Act would end, though other claims could remain. This example is made up to show how the rules fit together; it says nothing about any real case.

What mistakes do people make with the demand letter?

Sending the demand by email or regular mail instead of certified or registered mail with a return receipt.
Describing the problem in general terms without naming the particular violations of section 1770.
Filing a damages lawsuit before 30 days have passed since the notice.
Mailing the letter to an out-of-state headquarters when the statute names the place of the transaction or the California principal place of business.
Waiting until the three-year deadline is weeks away before starting the 30-day clock.
Throwing away the return receipt, which is the proof that the notice was sent and received.

What should I do this week?

Gather the receipt, contract, advertisement, texts and emails, and write down what you were told, by whom and when.
Find the address where the transaction took place and the business's California principal place of business.
Note the date of the practice and count three years forward, so the notice goes out well inside the deadline.
Draft a letter that names each practice from Civil Code 1770(a) and states the remedy you want.
Send it certified or registered mail, return receipt requested, and keep a copy, the mailing receipt and the green card.
Calendar day 30 and save every reply. Our list of what to bring to a first meeting with a lawyer works for these documents too.

Frequently asked questions

Does the 30-day notice apply in small claims court?

Section 1782 applies to "an action for damages" under the Act and does not carve out small claims. If a small claims case relies on the Act, sending the notice first is the safer course. Our guide on choosing small claims or a lawsuit for a consumer fraud loss compares the two courts.

Can I send the letter myself?

Yes. The statute requires a written notice from the consumer and does not require a lawyer to send it. What matters is the content, the delivery method and the address.

Does sending the letter stop the deadline?

Nothing in section 1782 or section 1783 pauses the three-year period while you wait for a response. The 30 days count inside that period, so start early.

What if the business ignores the letter?

If no appropriate remedy is given or agreed to within 30 days of receipt, the consumer may file a damages claim under the Act (Civil Code 1782(b)). The return receipt shows when the 30 days began.

Can a contract I signed waive these rights?

No. Any waiver by a consumer of the Act's provisions is contrary to public policy, unenforceable and void (Civil Code 1751).

Should I also report the business to the District Attorney?

You can do both. Our guide on reporting a business to the Sonoma County District Attorney or filing your own claim explains what each path can and cannot do.

Where would a lawsuit be filed in Sonoma County?

The Act allows filing in the county where the business is located or doing business, or where the transaction happened, with an affidavit showing the county is proper (Civil Code 1780(d)). For a local transaction, see what to expect at Sonoma County Superior Court. Our Sonoma County page lists the local offices.
