What you need to do when you sell or give away a vehicle in California

When you sell or transfer a vehicle in California, you must file a Notice of Transfer and Release of Liability with the Department of Motor Vehicles (DMV). This form protects you from being held responsible for traffic violations, accidents, or parking tickets that occur after the new owner takes possession. Without it, the DMV may continue sending you notices and bills for violations the new owner commits.

California law requires you to report the transfer within 5 days of the sale or gift. You can file online through the DMV website, by mail, or in person at a DMV office. The process is straightforward, but timing matters — waiting too long leaves you exposed to liability you should not have to pay.

Key Takeaways

  • You must file a Notice of Transfer and Release of Liability with the California DMV within 5 days of selling or transferring your vehicle to protect yourself from future violations and accidents.
  • The fastest method is filing online through the DMV website using your vehicle's VIN, license plate number, and the date of transfer.
  • If you sell to a private buyer, you should also get a signed bill of sale and keep a copy for your records in case disputes arise later.
  • The new owner is responsible for registering the vehicle in their name within 10 days, but your liability release does not depend on them completing that step.
  • If the new owner never registers the vehicle and commits violations, filing the transfer form protects you from being billed for those violations.

Filing online through the DMV website

The fastest way to release liability is through the California DMV's online system at dmv.ca.gov. Go to the "Register a Vehicle" section and select "Report a Sale of Vehicle." You will need your driver's license or ID number, the vehicle's VIN, the license plate number, and the date you transferred ownership. The form takes about 5 minutes to complete.

After you submit the form online, you receive a confirmation number when ready. The DMV processes the transfer within 1 to 2 weeks. Keep the confirmation number and the date you filed — if a violation notice arrives after your filing date, you can use that proof to dispute the charge. Online filing costs nothing and creates a timestamped record, which is why it is the preferred method for most sellers.

Mailing the form to the DMV

If you prefer to file by mail, read the Notice of Transfer and Release of Liability form (REG 138) from the DMV website. Fill in your name, address, driver's license number, the vehicle's VIN, license plate, and the date of transfer. Sign and date the form, then mail it to the DMV address listed on the form itself — the address varies by county.

Mail delivery takes 1 to 2 weeks, and DMV processing adds another 1 to 2 weeks, so the total time is roughly 3 to 4 weeks. Include a copy for your records. If you are concerned about proof of delivery, use certified mail with a return receipt so you have documentation that the DMV received it. This method is slower than online filing but works if you do not have internet access or prefer a paper trail.

Filing in person at a DMV office

You can also walk into any California DMV office with the completed REG 138 form and file it on the spot. Bring your driver's license or ID, the vehicle's registration, and the form. The staff will process it when ready and give you a stamped copy as proof. This method guarantees you have documentation the same day, which can be useful if you are selling to someone you do not fully trust.

The downside is that DMV offices are often crowded, and you may wait 30 minutes to an hour. If you have a busy schedule, online filing is faster. In-person filing makes sense only if you are already at the DMV for another reason or if you want the reassurance of handing the form directly to an employee.

What happens if you do not file the transfer form

If you sell a vehicle and do not file the Notice of Transfer and Release of Liability, the DMV still has your name on the registration. Any traffic violations, parking tickets, or accidents involving that vehicle will be sent to you. You will receive notices demanding payment, and your driving record may be affected. The new owner may not even know they are supposed to register the vehicle, leaving you liable for months or years of violations.

In extreme cases, unpaid violations can result in a suspended license or a judgment against you. The new owner has no incentive to register the vehicle quickly if they do not know about the important date, and you have no way to force them to do so. Filing the transfer form within 5 days cuts off your liability when ready, regardless of whether the new owner registers the vehicle on time.

Getting a bill of sale and keeping records

While the Notice of Transfer and Release of Liability protects you with the DMV, a bill of sale protects you in other ways. A bill of sale is a written record that you sold the vehicle to a specific person on a specific date for a specific price. It should include both your names, addresses, the vehicle's VIN and license plate, the sale price, and the date. Both you and the buyer should sign and date it.

California does not require a bill of sale by law, but it is essential for your protection. If the new owner gets into an accident and the other party sues, a bill of sale proves you no longer owned the vehicle. If a dispute arises about the sale price or condition, the bill of sale is your evidence. Keep a copy in your files along with your DMV filing confirmation number. Together, these two documents create a complete record of the transfer.

What the new owner must do

The person who buys or receives your vehicle must register it in their name within 10 days. They do this by taking the signed title (or pink slip), proof of insurance, and proof of residency to a DMV office or by mail. Your liability release does not depend on them completing this step — once you file the transfer form, you are protected even if they never register the vehicle.

However, if the new owner does not register the vehicle and commits violations, those violations will eventually be traced back to you through the old registration. The DMV will send you notices, but you can respond with a copy of your filed transfer form and the bill of sale to prove you no longer owned the vehicle at the time of the violation. This is why filing the transfer form quickly is so important — it creates a clear date that separates your ownership from theirs.

Frequently Asked Questions

What if I sell my car to a dealer instead of a private buyer?

Dealers handle the transfer paperwork themselves as part of the sale process. You should still file the Notice of Transfer and Release of Liability within 5 days to protect yourself, even though the dealer will also file their own paperwork. Ask the dealer for a receipt or written confirmation of the sale date so you have proof of when ownership changed hands.

Can I file the transfer form before I actually sell the vehicle?

No. The form requires the actual date of transfer, and filing it before the sale is complete creates a false record. File it only after the new owner has taken possession and you have received payment. If you are planning to sell soon, you can prepare the form in advance, but submit it only on or after the transfer date.

What if I give my vehicle to a family member instead of selling it?

The process is the same. You still file the Notice of Transfer and Release of Liability, and the recipient still has 10 days to register it in their name. Use the date you handed over the keys as the transfer date. A bill of sale is optional for gifts, but it is still a good idea to document the transfer in writing.

How long does it take for the DMV to process the transfer form?

Online filing is processed within 1 to 2 weeks. Mail filing takes 1 to 2 weeks for delivery plus 1 to 2 weeks for processing, so roughly 3 to 4 weeks total. In-person filing is when ready. Your liability is released as soon as the DMV receives and processes the form, not when you file it, so filing early matters.

What if a violation notice arrives after I filed the transfer form?

Contact the DMV with your filing confirmation number and the date you filed. Provide a copy of the transfer form and explain that the violation occurred after your transfer date. The DMV should remove the violation from your record. If the notice is from a court or collection agency, include your transfer documentation in your response and request that the charge be dismissed based on the transfer date.
