What Can Still Change After You Buy

A new policy covers you from the moment it is bound, but the company is still checking what you told it: your driving record, the vehicle, who lives in the household. That is why the first weeks matter — not because California gives a company a free hand to cancel a new policy, but because what verification turns up can change the price or, in a few cases, end the policy.

The only reasons a policy can be canceled

Insurance Code section 661 lists them. A notice of cancellation is effective only if it is based on one or more of these:

• Nonpayment of premium.
• A suspended or revoked driver's license or registration — the named insured's, or that of any other driver who lives in the household or customarily drives an insured car — during the policy period (for a renewal, also the 180 days before it began).
• Fraud by the named insured in pursuing a claim under the policy.
• Material misrepresentation of the safety record, annual miles driven, years of driving experience or record of prior claims of the named insured or a household member who customarily drives an insured car — or of another factor the Insurance Commissioner has found substantially related to the risk of loss.
• A substantial increase in the hazard insured against.

Section 661 does not treat a new policy's first weeks differently, and the notice rules in section 662 apply to every cancellation.

The notice you are owed

A cancellation is not effective unless the company mails or delivers notice at least 20 days before it takes effect; for nonpayment, at least 10 days' notice with the reason. And since 2025, a cancellation for nonpayment takes effect on the date in the notice only if you have not paid what is due by the end of that 10-day period (Insurance Code section 662). Pay inside the 10 days and the cancellation does not happen.

The 20-day fix for an honest mistake

If the problem is information you got wrong by mistake — a ticket you forgot, a mileage figure that was off — section 661 gives you a way out: an insured who negligently misrepresented it can avoid cancellation by giving the company corrected information within 20 days after receiving the notice and agreeing to pay any difference in premium for the time it was wrong.

What the first weeks are really for

• Answer requests quickly. If the company asks for a photo of the car, a copy of a license or another document, that request has a deadline behind it. In the calls we take, an unanswered request is one of the most common reasons a new policy runs into trouble.
• Expect a possible re-rate. If verification contradicts the application, the price is corrected. Better to hear it in week two than at a claim.
• Keep your documents. Save the declarations page and the ID cards the day they arrive, not the week you need them.

Non-renewal is a different animal

Cancellation ends a policy mid-term. Non-renewal declines the next term, and it has its own rule: a written notice at least 30 days before the policy expires, or an offer to renew at least 20 days before (Insurance Code section 663). If you receive a notice, read the top of it to see which one you are holding.

What to actually do

Put the company's number in your phone the day the policy starts. Open the mail from them. If something asks for a response, respond that week. If a new policy of yours was canceled, tell us what the notice said — the reason usually determines what happens next. The quote-ready checklist lists the documents worth having before you buy.
