Selling a Car in California: Smog, Title and Release of Liability

Selling a car in California comes down to three seller obligations: provide the buyer a valid smog certificate (for most vehicles), sign over the title correctly, and file a Notice of Transfer and Release of Liability with the DMV within 5 days. Get those right and you protect yourself from tickets, tolls, and liability tied to a car you no longer own.

The rest is about preparing the car, setting a fair price, and handling the handoff safely. Whether you're in Irvine, Costa Mesa, or Anaheim, the state rules are the same. Here's the seller's playbook from start to finish.

Step 1: get the paperwork in order before you list

Gather these before the first buyer calls:

• California Certificate of Title (the "pink slip"). If you still owe money on the car, the lender holds the title or is listed as legal owner; you'll need to pay off the loan and get the lien released first. If the loan is paid but the lender is still listed, a lien release (such as REG 166 or the lender's own release) may be needed. Our guide on buying a car with a lien explains the buyer's side.
• Lost title? Apply for a replacement or transfer using REG 227. Section 5 must be notarized if there's a legal owner or lienholder. See lost title in California.
• Maintenance records. Receipts build buyer trust and can support your price.
• A vehicle history report. Having one ready answers common buyer questions up front.

Step 2: handle the smog requirement

Under California Vehicle Code 24007, the seller must provide the buyer a valid smog certificate at the time of transfer. Key points:

• A passing smog certificate is valid for 90 days, so time your smog check close to listing.
• Vehicles 4 or fewer model years old don't need a smog inspection at transfer; the buyer pays a smog transfer fee instead.
• Transfers between a spouse or domestic partner, sibling, child, parent, grandparent, or grandchild are generally exempt.
• Electric vehicles are exempt from smog. Gas vehicles 1975 and older are exempt, and diesels 1997 and older or over 14,000 lb GVWR are exempt.
• Selling "as is" doesn't excuse you from the smog requirement.

If your car fails, you'll need repairs before you can provide a certificate. BAR's Consumer Assistance Program may help income-eligible owners with repair costs; check bar.ca.gov. Our guide on what to do if a car fails smog goes deeper.

Step 3: prepare and price the car

• Clean it thoroughly, inside and out. First impressions shape offers.
• Fix small, cheap problems like burned-out bulbs or worn wipers. Big repairs are a judgment call; you won't always recover the cost.
• Research prices using several pricing guides and comparable local listings in Orange County. Be realistic about mileage, condition, and history.
• Write an honest listing with clear photos, mileage, known issues, and maintenance highlights. Being upfront about problems reduces disputes later.

Step 4: show the car and accept payment safely

Let serious buyers arrange an independent inspection; it builds trust and speeds up the sale. Our Facebook Marketplace safety guide covers scams from the buyer's side, and many apply to sellers too.

Step 5: complete the transfer

At the sale, you'll typically:

1. Sign the title as the registered owner in the correct spot and fill in the odometer reading. A lienholder must also sign if applicable.
2. Complete REG 262 (Vehicle/Vessel Transfer and Reassignment) when needed, such as for odometer disclosure.
3. Fill out a bill of sale (REG 135) with the date, price, VIN, and both parties' information. Keep a copy. See our bill of sale guide.
4. Give the buyer the smog certificate.
5. Remove your license plates? In California, plates generally stay with the vehicle unless they're personalized or special plates you want to keep; check DMV rules for your plate type.
6. Remove personal items, garage openers, and toll transponders.

Step 6: file the Release of Liability within 5 days

Submit the Notice of Transfer and Release of Liability (NRL, REG 138) to the DMV within 5 days of the sale. You can do it online at dmv.ca.gov. This tells the DMV you no longer own the car, which helps protect you if the buyer gets parking tickets, toll violations, or is involved in a crash before re-registering.

The buyer is responsible for reporting the change of ownership to the DMV within 10 days and paying any transfer fees and use tax. Our Release of Liability guide has step-by-step instructions.

After the sale, also:

• Cancel or transfer your insurance once the transfer is complete
• Remove the car from your FasTrak account
• Keep copies of everything for your records

Frequently asked questions

Who pays for the smog check when selling a car in California?

The seller is responsible for providing a valid smog certificate for most vehicles, so the seller typically pays for the inspection. Buyers and sellers can negotiate, but the legal duty to provide the certificate stays with the seller.

Can I sell a car "as is" in California?

Yes, private-party sales are commonly "as is," and California's lemon law doesn't apply to private sales. However, "as is" doesn't excuse you from providing a smog certificate when one is required.

What if the buyer never registers the car?

That's why the Release of Liability matters. Filing it within 5 days creates a DMV record of the transfer date, which helps protect you from responsibility for later tickets and tolls.

Do I need a bill of sale for a private sale?

A bill of sale isn't always required, but it's a smart record for both parties, showing the date, price, and vehicle details. The DMV's REG 135 form is a convenient option.

Should I trade in instead of selling privately?

It depends on how much effort you want to spend versus how much money you want to get. Our trade-in vs. private sale guide compares both paths.
