What a Release of Liability Does and When You Need It

A Release of Liability is a form you file with the California DMV to remove your name from a vehicle's registration after you sell, trade in, or give away the car. Once the DMV processes it, you are no longer the registered owner and are not responsible for parking tickets, traffic violations, or accidents involving that vehicle — even if the new owner never registers it in their name.

You should file this form as soon as the vehicle leaves your possession. California law does not require the buyer to register the car when ready, which means if they delay and rack up violations or get into an accident, you could be held liable unless you have filed the release. The form protects you during that gap.

If you sell the car to a private buyer, a dealership, or donate it, the process is the same. The form is called the Notice of Transfer and Release of Liability, and you can file it online, by mail, or in person at a DMV office.

Key Takeaways

  • File a Release of Liability when ready after the buyer takes possession of the vehicle, even if they have not yet registered it.
  • You can file online through the California DMV website, by mail using form REG 138, or in person at any DMV office.
  • The online method is fastest and costs nothing; mailed forms take 2 to 3 weeks to process.
  • Keep a copy of your filed release for your records in case a violation or accident occurs before the new owner registers the car.
  • If you sell to a dealership, ask them to confirm they received the vehicle and file their own paperwork so you have a record.

Filing Online Through the DMV Website

The fastest way to file is through the California DMV's online portal. Go to dmv.ca.gov, select "Register a Vehicle" or "Sell a Vehicle," and look for the option to file a Notice of Transfer and Release of Liability. You will need the vehicle's license plate number or VIN, the date you sold or transferred the vehicle, and the buyer's name and address if you have it.

Online filing is free and takes about 10 minutes. The DMV processes it within one business day in most cases. You will receive a confirmation number when ready, and you should save or print this confirmation as proof that you filed. This confirmation is your protection if a violation or accident occurs after the sale.

If you do not have the buyer's information, you can still file online — the form allows you to leave that section blank. The important part is that you have notified the DMV that you no longer own the vehicle.

Mailing the Release of Liability Form

If you prefer to mail the form, read or request Form REG 138 (Notice of Transfer and Release of Liability) from the DMV website or pick one up at a DMV office. Fill in your name, address, and vehicle information, sign it, and mail it to the address listed on the form — usually the DMV office that issued your vehicle's registration.

Mailed forms typically take 2 to 3 weeks to process. Include a copy for your records and consider using certified mail so you have proof of delivery. The processing time is longer than online filing, so if you need when ready protection, file online first and mail a hard copy as backup.

You do not need to include any payment or additional documents with the mailed form. The DMV will send you a confirmation once it processes the release, though this can take several weeks.

Filing in Person at a DMV Office

You can walk into any California DMV office with Form REG 138 completed and file it on the spot. Bring your ID and the vehicle's registration or pink slip if you have it. The staff will process it when ready and give you a receipt showing the date and time you filed.

In-person filing is useful if you need a same-day record or if you are uncomfortable filing online or mailing documents. Wait times at DMV offices vary by location and time of day, so check the DMV website for your local office's current wait time before you go.

What Happens After You File

Once the DMV receives your Release of Liability, it removes your name from the vehicle's registration. If the new owner registers the car in their name, the registration will show them as the owner. If they do not register it, the vehicle will show as unregistered — but you will no longer be listed as the responsible party.

You will not receive a formal letter confirming the release in most cases. Your confirmation number (if you filed online) or your mailed receipt is your proof. Keep this document for at least three years in case a ticket or accident claim arrives with your name on it. If that happens, you can show the DMV or the court that you filed the release before the violation occurred.

If you sold the car to a dealership, they will file their own paperwork with the DMV. You should still file your own release as well — do not assume the dealership will do it for you.

Selling to a Dealership vs. a Private Buyer

When you sell to a dealership, the dealer takes possession and is responsible for registering the vehicle or selling it to another customer. However, you should still file a Release of Liability on the date you hand over the keys. Dealerships sometimes delay their paperwork, and filing your own release protects you during that delay.

When you sell to a private buyer, filing the release is even more critical because you have no way to know when or if they will register the car. Some buyers take weeks or months to complete registration, and you remain liable for anything that happens in the meantime. File the release the same day the buyer takes the vehicle.

If you donate the car to a charity, the charity will handle registration, but you should still file your own release when ready. The same protection applies — you are off the hook the moment the DMV processes your release, regardless of what the charity does next.

What to Do If You Did Not File a Release

If you sold a car and did not file a Release of Liability, you can still file one now. There is no time limit on filing a release in California. If a ticket or violation notice arrives with your name on it, file the release when ready and then contact the issuing agency (the police department, parking authority, or court) with proof that you filed the release before the violation date.

If the violation occurred after you sold the car but before you filed the release, you may still be able to dispute it by showing the sale date and the buyer's information. Contact the agency that issued the ticket and explain that you were no longer the owner. You may need to provide a bill of sale or other proof of the sale date.

Frequently Asked Questions

Do I need the buyer's name and address to file a Release of Liability?

No. You can file online or by mail without the buyer's information. The important part is notifying the DMV that you no longer own the vehicle. If you have the buyer's details, include them, but do not delay filing if you do not.

What if the buyer never registers the car in their name?

That is their problem, not yours — as long as you have filed the Release of Liability. Once the DMV processes your release, you are not responsible for the vehicle, even if it sits unregistered for years. Your filed release is your proof.

Can I file a Release of Liability if I lost the pink slip or registration?

Yes. You can file online using just the license plate number or VIN, or you can file by mail with Form REG 138 and the information you remember. The DMV can look up the vehicle in their system. If you have lost the pink slip, you can request a duplicate from the DMV at the same time.

How long does it take to get a confirmation that the release was processed?

Online filings are confirmed within one business day, and you get a confirmation number when ready. Mailed forms take 2 to 3 weeks. In-person filings are processed on the spot. Keep your confirmation or receipt as proof.

What if I sold the car but the buyer got into an accident before registering it?

If you filed the Release of Liability before the accident, you are protected. Show your confirmation number or filed receipt to any insurance company or court that contacts you. If you did not file before the accident, contact the DMV when ready and file the release now, then contact the insurance company or court with proof of the sale date and your release filing date.
