Selling a vehicle in California comes with more rules than most states, and sellers who miss a step often find out the hard way. Parking tickets, toll violations, DMV notices, or even liability issues can follow you long after the car is gone if the sale isn’t handled correctly. California places a heavy emphasis on emissions compliance and seller reporting, making it critical to understand your responsibilities before you sell.
This guide explains exactly how to sell a car in California, whether it’s running or not, newer or older, privately owned or still financed.
What California Requires Before You Sell
California requires a valid certificate of title for nearly all vehicle sales. Before selling, confirm:
- Your name matches the title exactly
- Any lien listed on the title has been fully released
- All owners listed on the title are available to sign
- The VIN on the vehicle matches the title
California does not require notarization of vehicle titles, which simplifies signing, but the state makes up for that with strict reporting and emissions rules.
Title and Paperwork Rules in California
Title Signing
When selling a vehicle in California:
- The seller signs the title exactly as printed
- All owners listed must sign
- No notarization is required
- Cross-outs or corrections can delay registration
Titles should be completed carefully. Errors can cause transfer delays and invite unwanted follow-up from the buyer.
Odometer Disclosure
Odometer disclosure is required for vehicles that are not exempt due to age. Mileage must be entered accurately at the time of sale. Incorrect mileage reporting can result in fines and long-term legal issues.
Bill of Sale
A bill of sale is recommended for California vehicle sales. While the title documents ownership transfer, a bill of sale helps document the sale price, date, and condition of the vehicle for both parties.
Smog and Emissions Rules (Critical in California)
California usually places the smog certification responsibility on the seller, not the buyer. This is one of the most important differences between California and other states.
Key points:
- Most gasoline-powered vehicles require a valid smog certificate
- Certain vehicles may be exempt based on age or fuel type
- Selling without addressing smog requirements can stall or kill a sale
Vehicles that cannot pass smog often sell for less or require alternative selling options.
License Plates, Registration, and Seller Liability
In California, license plates stay with the vehicle, not the seller. Removing the plates is not permitted in standard private sales.
Notice of Transfer and Release of Liability
California sellers must file a Notice of Transfer and Release of Liability promptly after selling. This step is essential.
Failing to file this notice can result in:
- Parking or toll violations mailed to you
- DMV records still showing you as the owner
- Liability if the vehicle is involved in an incident
Once filed, your responsibility for the vehicle officially ends.
Taxes and Fees
- Buyers are responsible for use tax and registration fees
- Sellers are not responsible for buyer taxes after the sale
- Accurately recording the sale date protects you from future issues
Keep copies of all paperwork for your records.
Special Situations California Sellers Should Understand
- Selling with a lien: The lien must be paid off and released before ownership can transfer.
- Two names on the title: All listed owners must sign unless the title clearly states “OR.”
- Lost title: Replacing the title before selling avoids delays and buyer hesitation.
- Non-running vehicles: These can be sold, but smog rules significantly impact value and buyer options.
Getting Paid Safely
Private sales in California attract scams, especially with high-value vehicles. Fake cashier’s checks, delayed payments, and third-party shipping stories are common. Never release the title or vehicle until payment is fully verified and cleared.
For many sellers, minimizing risk is more important than navigating private-sale uncertainty.
