What a California Release of Liability Does and When You Need It

A Release of Liability is a form you file with the California DMV to officially remove yourself from responsibility for a vehicle you no longer own. Once the DMV processes it, you are no longer liable for parking tickets, traffic violations, accidents, or registration fees tied to that car — even if the new owner never registers it in their name.

You file this form when you sell, trade in, or give away a vehicle. Without it, the DMV's records still show you as the registered owner, which means citations and bills can follow you. The form protects you from liability that accrues after you hand over the keys.

California law does not require the buyer to register the vehicle when ready, and some buyers delay or never complete registration. A Release of Liability protects you during that gap. It is also your proof that you reported the sale, which matters if a dispute arises later.

Key Takeaways

  • File Form REG 138 (Release of Liability) within 5 days of selling your vehicle to protect yourself from future liability tied to that car.
  • You can file online through the California DMV website, by mail, or in person at a DMV office — online is fastest and requires no fee.
  • Include the buyer's name and address if you have it, but you can file without that information if the sale was private and informal.
  • Keep your copy of the filed form as proof you reported the sale, in case the new owner causes damage or incurs violations before registering.
  • Filing does not transfer the title; the buyer must complete their own registration separately to become the legal owner.

Form REG 138: What Information You Need to Provide

The form you file is Form REG 138, officially called "Notice of Transfer and Release of Liability." It is a single page that asks for your name and address, the vehicle's VIN and license plate number, the date of sale, and the buyer's name and address if you have it.

If you sold the car to a private buyer and do not have their full details, you can still file. Leave the buyer information blank and note the date you handed over the vehicle. The DMV will process the form and remove you from liability based on that date. Having the buyer's information is helpful but not required to protect yourself.

You will also need the vehicle's current registration card or the pink slip (title) to confirm the VIN and plate number. If you sold the car to a dealer or trade-in center, they will often handle the Release of Liability for you, but you should confirm this before leaving the lot.

Filing Online, by Mail, or In Person

The fastest route is the California DMV website. Go to dmv.ca.gov, search for "Release of Liability," and you can file Form REG 138 online without leaving home. There is no fee, and the DMV processes online filings within days. You will need your vehicle's VIN, license plate number, and the sale date. You can include the buyer's information if you have it, but it is optional.

If you prefer to mail the form, print Form REG 138 from the DMV website, fill it out by hand, and send it to the address listed on the form. Mail takes longer — typically one to two weeks — so file as soon as you hand over the keys. Do not mail the pink slip or title; keep that until the buyer completes their registration.

You can also file in person at any California DMV office. Bring your ID, the vehicle's registration card or title, and the completed form. Walk-in service is available, though wait times vary by location. In-person filing is useful if you want when ready confirmation that the form was received.

What Happens After You File

Once the DMV receives your Release of Liability, they update their records to show the vehicle is no longer registered to you. This usually takes a few days for online filings and one to two weeks for mail. You will not receive a confirmation letter in most cases, but you can check the status of your filing on the DMV website using your VIN.

The buyer then has a separate responsibility to register the vehicle in their name. They will need the pink slip (title) that you signed over to them, proof of insurance, and their own ID. If they do not complete registration within a certain timeframe, the vehicle may be flagged as unregistered, but that liability no longer falls on you once your Release of Liability is filed.

Keep a copy of your filed Release of Liability form for your records. If a citation or bill arrives after you filed, you have proof that you reported the sale. This is especially important if the new owner causes an accident or racks up parking tickets before registering the vehicle.

Timeline: When to File and How Long It Takes

California law does not impose a strict important date, but the DMV recommends filing within 5 days of the sale. The sooner you file, the sooner you are protected. If you wait weeks or months, you remain liable for anything that happens to the vehicle in the meantime.

Online filings are processed within 1 to 3 business days. Mail filings take 1 to 2 weeks, depending on postal delays and DMV processing volume. If you file in person, the office will stamp your copy when ready, though the DMV's system update may take a few days.

If you sold the car to a dealer or trade-in center, ask them when they will file the Release of Liability. Some dealers file it the same day; others take longer. Get confirmation in writing or email so you have a record of when they filed on your behalf.

What Happens If You Do Not File

If you do not file a Release of Liability, the DMV's records still show you as the registered owner. Any parking tickets, traffic violations, or registration fees tied to the vehicle will be sent to you. You can dispute these by proving you sold the car, but that requires documentation and time.

If the new owner causes an accident and does not have insurance, or if they cause property damage, you could be contacted as the registered owner. While you may not be legally liable in all cases, you will have to prove you no longer own the vehicle. A filed Release of Liability prevents this headache entirely.

In rare cases, if the vehicle is used in a crime or abandoned, law enforcement may contact you as the registered owner. Again, a Release of Liability protects you by showing you reported the sale and are no longer responsible.

Release of Liability vs. Title Transfer: What Is the Difference

A Release of Liability removes you from responsibility for the vehicle but does not transfer ownership. A title transfer is what the buyer does to become the legal owner. These are two separate processes.

When you sell a car, you sign the back of the pink slip (title) and hand it to the buyer. That signature is your part of the title transfer. The buyer then takes the signed title to the DMV and registers the vehicle in their name. You file the Release of Liability at the same time or shortly after to protect yourself during the gap before they complete their registration.

If you sell to a dealer, they handle both the title transfer and the Release of Liability. If you sell privately, you are responsible for filing the Release of Liability, and the buyer is responsible for registering the title. Do not assume the buyer will do it — file your Release of Liability regardless.

Frequently Asked Questions

Can I file a Release of Liability if I already sold the car weeks ago?

Yes. File it as soon as you realize you have not done so. The form asks for the date of sale, so the DMV will process it based on that date. You will be protected from liability going forward, though you may still be responsible for anything that occurred between the sale and the filing date.

What if the buyer never registers the vehicle?

That is the buyer's problem, not yours — once your Release of Liability is filed. If citations or bills arrive after you filed, you can show the DMV your Release of Liability as proof you reported the sale. The DMV may then pursue the buyer or flag the vehicle as unregistered.

Do I need the buyer's information to file?

No. You can file with just the vehicle's VIN, license plate, and the sale date. The buyer's information is helpful but optional. If you sold the car privately and do not have their full name and address, leave those fields blank and file anyway.

Is there a fee to file a Release of Liability?

No. Filing online, by mail, or in person is free. Do not pay anyone to file this form for you — you can do it yourself in minutes.

What if I sold the car to a dealer or trade-in center?

Ask the dealer in writing or email when they will file the Release of Liability. Most dealers file it the same day or within a few days. Get confirmation so you have a record. If they do not file within a week, file it yourself to be safe.
