Quick answer
California has no general right to cancel any contract within 3 days. The 3-day right applies to specific sales, such as home solicitation and seminar sales of $25 or more, where you can cancel until midnight of the third business day after signing (the fifth for buyers 65 or older) under Civil Code sections 1689.6 and 1689.20. Other deals have their own windows, and some have none.

Do you have 3 days to cancel any contract in California?
No. A signed contract is generally binding from the moment you sign it. A right to cancel exists only where a statute or the contract itself creates one. California and federal law create those rights for sales where pressure and surprise are common: sales at your home, at seminars, at gyms, at timeshare presentations, and, as of October 1, 2026, used cars from dealers.
If your purchase is not on the list below, look for a cancellation or return clause in the contract itself, and check whether the seller made promises it did not keep.
Which California contracts have a cooling-off period?
| Type of contract | Time to cancel | Rule |
|---|---|---|
| Home solicitation: a sale of goods or services for $25 or more made anywhere other than the seller's place of business, such as your home | Midnight of the 3rd business day after signing; 5th if you are 65 or older | Civil Code 1689.5, 1689.6 |
| Repair or restoration of a home damaged by a disaster, sold at your home | Midnight of the 7th business day after signing | Civil Code 1689.6(c) |
| Personal emergency response unit sold at home | Midnight of the 7th business day | Civil Code 1689.6(b) |
| Seminar sale of $25 or more, made somewhere other than your home | Midnight of the 3rd business day; 5th if you are 65 or older | Civil Code 1689.20, 1689.24 |
| Gym or health studio contract | Midnight of the 5th business day of the health studio, excluding Sundays and holidays; 20, 30 or 45 days for contracts of $1,500 or more | Civil Code 1812.85 |
| Timeshare purchase | 7 calendar days after signing or receiving the public report, whichever is later | Business and Professions Code 11238 |
| Used car from a dealer, $50,000 or less (from October 1, 2026) | Three calendar days from the day after signing, to the dealer's close of business (longer if the dealer is closed on day three); lost once the car is driven more than 400 miles | Civil Code 1784.31, 1784.43 |
| Federal door-to-door sale: $25 or more at your home, $130 or more at a temporary location | Midnight of the 3rd business day | FTC Cooling-Off Rule, 16 CFR 429 |
Contracts that contractors write under section 7151.2 of the Business and Professions Code start the clock later, when you receive a signed and dated copy (Civil Code section 1689.6(a)(2)); the period is still three business days, or five for seniors. Timeshares are exempt from the home solicitation and seminar rules and follow their own seven-day rule; see our guide on how to cancel a timeshare in California.

How do you count business days for a cancellation?
For home solicitation sales, a business day is any calendar day except Sunday and nine named holidays: New Year's Day, Washington's Birthday, Memorial Day, Independence Day, Labor Day, Columbus Day, Veterans Day, Thanksgiving and Christmas (Civil Code section 1689.5(e)). Saturday counts.
Example (hypothetical): you sign a home solicitation contract on a Thursday. Friday is day one, Saturday day two, Sunday is skipped, and Monday is day three. Your notice is on time if you mail it by midnight Monday. A 67-year-old buyer in the same position would have until midnight Wednesday.
How to cancel a contract in writing
Cancellation happens when you give written notice to the seller at the address or email address in the agreement. A mailed notice is effective when you deposit it in the mail, properly addressed and with postage paid. Your wording does not have to match the seller's form; any written notice showing you do not intend to be bound is effective (Civil Code section 1689.6(d) to (f)).
- Find the Notice of Cancellation form attached to your contract, or write your own short notice.
- Include your name, the seller's name, the contract date and a plain statement that you cancel.
- Sign and date it, and keep a copy.
- Deliver it to the mailing address or email address the agreement names for cancellations. If you mail it, use certified mail and keep the receipt, which shows the date you deposited it.
- If you also email it, save the sent message.
- Keep any delivered goods in substantially as good condition as when they arrived, ready for the seller to collect, or return them under the seller's instructions at its expense and risk.
I cancel the contract I signed with ClearFlow Home Systems at my home on Thursday, May 7, for a water filtration system priced at $9,000. This notice is given under California Civil Code section 1689.6 before midnight of the third business day. Please return my $900 down payment within 10 days and cancel any financing or security interest connected with the sale.
After a valid cancellation of a home solicitation sale, the seller must return your payments and any note within 10 days (Civil Code section 1689.10). The required notice form says that if the seller does not pick up goods within 20 days of your notice, you may keep or dispose of them without further obligation.
Which purchases have no cooling-off period?
- New cars. The dealer cooling-off right added as of October 1, 2026 covers used vehicles only. Our guide to car dealer fraud in California covers misrepresentation claims.
- Used cars over $50,000, motorcycles, or private-party sales. The new dealer rule does not reach them.
- Purchases made at a store or the seller's office. California's home solicitation rule reaches only sales made somewhere other than the seller's place of business, and the FTC rule excludes sales at the seller's permanent location.
- Online, mail and phone orders. The FTC rule excludes them, though return policies and the shipping rules in our guide to undelivered online orders may help.
- Real estate, insurance and securities, which are excluded from the FTC rule and governed by their own laws.
If you cancel a qualifying used-car purchase made on or after October 1, 2026, the dealer can keep a restocking fee: 1.5 percent of the sale price, with a $200 minimum and a $600 maximum, plus $1 for each mile over 250, up to $150 more (Civil Code section 1784.31). To cancel, you bring the car back to the dealer yourself during business hours; the dealer then has 48 hours to cancel the contract and refund you (section 1784.43). Before October 1, 2026, dealers instead had to offer buyers of many used cars a paid contract cancellation option.
What if the seller refuses to honor your cancellation?
Put the dispute in writing. A short demand letter that attaches your cancellation notice and mailing receipt, cites the statute and asks for the refund by a set date creates a clean record. If the contract lacked the required notice, say so; section 1689.7(g) lets you cancel until the seller complies.
Gym contracts raise their own issues, covered in our guide on cancelling a gym membership in California. If you paid by card, a billing dispute may run alongside the letter.
When an attorney-written cancellation letter makes sense
A cooling-off right is designed for the buyer to use alone, with a short signed note. The trouble starts when a seller will not accept it: a timely cancellation ignored, a down payment kept, financing that was never released, or a claim that the deadline passed when the contract never carried the required notice.
For those disputes, through Talk to My Lawyer, a licensed California attorney writes your letter from your contract, notice and receipts, cites the cancellation rule that fits your sale, and sends it on your behalf. If your contract falls outside these statutes, whether you can undo it depends on its terms and your facts, which a lawyer can assess.
Frequently asked questions
Is there a 3-day right to cancel a car purchase in California?
Yes. Starting October 1, 2026, a dealer selling you a used car for $50,000 or less must offer that right. The CARS Act gives a three-day right to cancel, starting the day after signing and ending at close of business, unless the car was driven more than 400 miles. Dealers may charge a capped restocking fee. New cars and private-party sales have no cooling-off period.
Do seniors get more time to cancel in California?
Yes, for home solicitation and seminar sales. A buyer who is 65 or older can cancel until midnight of the fifth business day after signing, instead of the third (Civil Code sections 1689.6 and 1689.20). It covers contracts signed on or after January 1, 2021. The contract's cancellation statement must reflect the five-day period for senior buyers.
Does Saturday count as a business day for cancelling a contract?
Under California's home solicitation law, yes. Civil Code section 1689.5 defines a business day as any calendar day except Sunday and nine listed holidays. The FTC's Cooling-Off Rule also counts Saturdays. Gym contracts use the health studio's business days, excluding Sundays and holidays. Timeshare cancellations count calendar days.
Can I cancel a contract by email in California?
For home solicitation and seminar sales, yes, if you send it to the email address specified in the agreement. Section 1689.6 says cancellation occurs when written notice reaches the seller at the address or email address in the contract. Health studio contracts also allow email from an address on file. Keep the sent message and consider a mailed copy too.
What if the seller never gave me a cancellation form?
Under Civil Code section 1689.7(g), a home solicitation buyer may cancel until the seller has met the notice rules, which include a detachable Notice of Cancellation form attached to the contract. You can still send your own written notice now. A lawyer can explain how this applies to your contract.
