Buying a used car in California comes down to a short sequence: confirm the title is clean and the seller can legally transfer it, get a current smog certificate from the seller, line up insurance that meets the state’s 2025 minimums, sign the title and bill of sale, and file the transfer with the DMV within 10 days of the sale. Miss that 10-day window and penalties stack on top of the use tax and fees you already owe. The steps below walk through what each stage requires and what it costs.
Verify the Title Before You Pay
Ask to see the physical California Certificate of Title, not a photo or a copy. The name on the front must match the person selling you the car. If a lienholder is listed, the seller has to pay off the loan and obtain a formal lien release before the title can transfer to you cleanly.1California DMV. Vehicle Titles A car with a lien still showing cannot be registered in your name until the DMV receives proof the lien is released. If the seller tells you the title is “at home” or “in the mail,” wait or walk.
Run the VIN through the National Motor Vehicle Title Information System before you hand over money. NMVTIS pulls data from every state motor vehicle agency, insurance companies, and salvage yards, and it will show title brands, the most recent odometer reading, and whether the car was ever reported as a total loss, salvage, or junk vehicle.2American Association of Motor Vehicle Administrators. NMVTIS for General Public and Consumers Federal law requires the seller to make a written mileage disclosure on the title at the time of sale.3National Highway Traffic Safety Administration. Odometer Fraud Compare the number on the title to the number on the dashboard and to any history-report readings. A mismatch is a reason to stop.
Smog Certificate and VIN Verification
California puts the smog certificate on the seller. They must give you a valid certificate issued within the last 90 days showing the car meets current emission standards. Gasoline, hybrid, and alternative-fuel vehicles that are eight model years or newer are exempt from the biennial smog check; in that case the buyer pays an $8 smog transfer fee at registration instead.4California Bureau of Automotive Repair. Smog Check: When You Need One and What’s Required5California Department of Motor Vehicles. Appendix 1F – Fees
If the car was last registered in another state, it also needs a VIN verification. An authorized officer physically inspects the vehicle identification number and confirms it matches the out-of-state title. That step is the buyer’s responsibility and happens as part of California registration.
Line Up Insurance Before You Drive It Home
You need active liability coverage in place before you leave the seller’s driveway, and you’ll need proof of it to register. California raised its minimums effective January 1, 2025:6California Department of Insurance. New Year Means New Changes for Insurance
- $30,000 for bodily injury or death of one person per accident (up from $15,000)
- $60,000 for bodily injury or death of all persons per accident (up from $30,000)
- $15,000 for property damage per accident (up from $5,000)
That 30/60/15 is a legal floor. If you already insure another vehicle, call your carrier to add the new car before you take possession. If this is your first car, bind a policy that takes effect by the sale date.
The Paperwork the Sale Requires
The California Certificate of Title does most of the work. Under Vehicle Code Section 5900, the seller signs the back to release ownership and the buyer fills in name, address, and driver’s license number.7California Legislative Information. California Vehicle Code 5900 The seller’s signature must match the printed name on the front; any mismatch means a rejected application.
If the title is lost or missing, both parties complete an Application for Replacement or Transfer of Title (REG 227). The seller fills out the ownership and missing-title sections; the buyer completes the new-owner sections.8California State Department of Motor Vehicles. Application for Replacement or Transfer of Title (REG 227) If the title was already replaced within the previous 90 days, the DMV requires a CHP vehicle verification on top of everything else.
A Bill of Sale (REG 135) records the final purchase price. The DMV calculates your use tax from that number, so what you write on the bill of sale needs to match what you actually paid.9California State Department of Motor Vehicles. Calculating Use Tax Amount Understating the price to shrink the tax bill is fraud, and the DMV has seen every version of it. An unusually low number will trigger a request for a Statement of Facts (REG 256) and the tax may be assessed on the higher market value anyway.
When the title doesn’t have a compliant odometer disclosure section, you’ll also need a Vehicle/Vessel Transfer and Reassignment Form (REG 262). Both buyer and seller sign it, and it records the mileage at the time of sale. A REG 262 is also required when a REG 227 is used for a replacement title or when the sale involves multiple transfers in the chain of ownership. Any alteration voids the odometer disclosure, which means starting over with a fresh REG 262 and a REG 256 explaining the fix.10State of California Department of Motor Vehicles. Vehicle/Vessel Transfer and Reassignment Form (REG 262) Fill the forms out before your appointment. Incomplete applications are the top reason people leave the DMV without their registration.
Register with the DMV Within 10 Days
Vehicle Code Section 5902 gives you 10 days from the purchase date to submit your transfer application.11California Legislative Information. California Vehicle Code 5902 That is tighter than most buyers plan for, especially if you’re still chasing down a form or waiting for insurance to activate. Miss it and a penalty is added to your fees.
You can mail the signed title, supporting forms, and payment to DMV, PO Box 942869, Sacramento, CA 94269, or bring everything to a local DMV office. Booking an appointment online beats the walk-in line.12California State Department of Motor Vehicles.

Make Sure the Seller Files Their Release of Liability
Vehicle Code Section 5900 requires the seller to notify the DMV of the sale within five calendar days.7California Legislative Information. California Vehicle Code 5900 That filing, the Notice of Transfer and Release of Liability (NRL), tells the DMV ownership has changed and protects the seller from being chased for parking tickets, traffic violations, and civil claims tied to the car after the sale date.17California State Department of Motor Vehicles. Notice of Transfer and Release of Liability FAQs This is the seller’s job, not yours, but it matters to you in one way: if you drag your feet on registering, and the seller hasn’t filed an NRL, their name is still on the record and the enforcement system still points at them. Confirming they’ve filed it is a courtesy that avoids an angry call later.
Buying from a Dealer Adds Protections
Dealers come with consumer protections that private sales do not. Federal law requires every dealer to post a Buyers Guide on the window of each used vehicle before offering it for sale. The guide must state whether the car comes with a warranty or is sold without one, and it becomes a legally binding part of the purchase contract.18eCFR. Part 455 Used Motor Vehicle Trade Regulation Rule
If a warranty is included, the Buyers Guide has to list the specific covered components, how long the coverage lasts, and what percentage of repair costs the dealer will pay. Shorthand like “drive train” isn’t allowed. The guide also tells you whether any manufacturer warranty still applies and reminds you that you can have your own mechanic inspect the vehicle.18eCFR. Part 455 Used Motor Vehicle Trade Regulation Rule A verbal promise from a salesperson is not a warranty. If it isn’t on the window form, assume it doesn’t exist.
California layers an implied-warranty rule on top of the federal one. Dealers selling used vehicles here generally cannot fully disclaim implied warranties the way a private seller can, meaning the car must be reasonably safe and functional for ordinary driving for a limited period even without a separate written warranty. Private sales carry no such backstop, which is part of why the same car tends to cost more at a dealer.
Whichever route you take, keep originals of everything: signed title, bill of sale, smog certificate, insurance documents, and any warranty paperwork. The DMV needs originals to process the registration, and those records are your only proof of the transaction if something goes sideways later.
