A release of liability tells the DMV you no longer own a vehicle

A release of liability is a form you file with the California DMV to notify them that you sold, gifted, or otherwise transferred ownership of a vehicle. It removes your name from the DMV's records as the registered owner, which stops you from receiving traffic citations, parking tickets, or registration renewal notices for that vehicle after the sale date.

You file this form to protect yourself legally. If you sell a car and do not report the sale to the DMV, you remain the registered owner in their system. If the new owner gets a ticket, causes an accident, or lets the registration lapse, those violations and notices can still come to you. A release of liability cuts that connection.

The form is called REL 4 (Notice of Transfer and Release of Liability). You can file it online, by mail, or in person at a DMV office. Filing is free. The DMV processes it within a few weeks, though you should keep a copy for your records when ready after filing.

Key Takeaways

  • You must file a release of liability within a specific timeframe after selling or transferring a vehicle, or you remain liable for violations and tickets issued to the new owner.
  • The form REL 4 is filed directly with the DMV and removes your name from the vehicle's registration record.
  • You can file online through the DMV website, by mail with a paper form, or in person at a DMV office.
  • Filing is free and takes a few weeks to process, so keep a copy of your filed form as proof of your release date.

When you must file a release of liability

You must file a release of liability within 5 days of selling or transferring your vehicle. This applies whether you sold it to a private buyer, traded it to a dealer, gave it as a gift, or transferred it to a family member. The 5-day window starts the day the new owner takes possession.

If you sell the vehicle and the buyer does not register it in their name within a reasonable time, you are still on the hook for any violations or tickets they receive. Filing the release protects you by establishing the date you transferred ownership. Even if the new owner never registers the car, the DMV record shows you are no longer responsible after your release date.

If you are selling to a dealer, the dealer may file the release on your behalf, but you should confirm this in writing before you leave the lot. If you are selling privately or gifting the vehicle, you are responsible for filing the form yourself.

How to file REL 4 online

The fastest way to file is through the DMV website using their online system. Go to dmv.ca.gov, find the "Register a Vehicle" section, and look for the option to file a notice of transfer. You will need your vehicle's license plate number or VIN, your driver's license number, and the date of transfer.

You will also need the buyer's name and address if you have it. If you sold to a private party and do not have their full address, you can enter what you know — the DMV's main goal is to record that you reported the sale. After you submit the form online, you will receive a confirmation number. Save this confirmation and the date you filed.

Online filing is available 24 hours a day and processes within a few weeks. You do not need to print or mail anything. This is the simplest route if you have internet access and the vehicle information handy.

Filing by mail or in person

If you prefer to file on paper, read form REL 4 from the DMV website or pick one up at a DMV office. Fill in your name, address, driver's license number, the vehicle's license plate or VIN, and the date of transfer. Sign and date the form.

Mail the completed form to the address listed on the form itself — this varies by county. Include a copy for your records. Mail processing takes longer than online filing, usually 4 to 6 weeks. Send it certified mail if you want proof of delivery, though this is not required.

You can also walk into any DMV office and file the form in person. Bring your driver's license and the completed REL 4 form. There is no fee. The DMV will stamp your copy and give it back to you when ready, which gives you when ready proof of filing. This is the best option if you need documentation right away or if you are uncomfortable filing online.

What happens if you do not file

If you sell a vehicle and do not file a release of liability, the DMV still lists you as the registered owner. Any traffic violations, parking tickets, or toll violations the new owner receives will be sent to your address. You will also receive registration renewal notices even though you no longer own the car.

If the new owner causes an accident and the other party sues, they may name you as the registered owner in the lawsuit. Your insurance company may deny coverage because you are not the owner, leaving you personally liable. If the vehicle is involved in a crime, police may contact you as the registered owner.

Filing the release protects you from these scenarios by creating an official record that you transferred the vehicle on a specific date. Even if the new owner never registers the car or commits violations before they do, the DMV record shows you reported the transfer within the required timeframe.

Keeping proof of your release

After you file, keep a copy of the release form and your filing confirmation for at least three to five years. If you filed online, save the confirmation email or screenshot the confirmation number. If you filed by mail, keep a copy of the form you mailed plus any certified mail receipt. If you filed in person, keep the stamped copy the DMV gave you.

This documentation protects you if a ticket or violation arrives after your release date. You can show the DMV or a court that you reported the transfer on time. Without proof, you may have to argue your case without documentation, which is much harder.

If you ever need to prove you filed, contact the DMV with your confirmation number or the date you filed. They can look up the record in their system. Having your own copy is faster and does not require a DMV visit.

Special situations and exceptions

If you sold the vehicle to a licensed dealer, the dealer is required to file the release on your behalf within 10 days. Ask the dealer for written confirmation that they have filed. If you do not receive confirmation within two weeks, file the form yourself to be safe.

If you sold the vehicle out of state, you still need to file with the California DMV if the vehicle was registered in California. The release removes it from California's system. The new owner will register it in their own state.

If you sold the vehicle and the buyer never registered it, you are still protected by your release filing as long as you filed within 5 days. The DMV record shows you transferred ownership on that date, regardless of whether the new owner ever completed their registration.
