What a California DMV Liability Release Is

A liability release is a form you file with the California DMV when you sell or transfer a vehicle and want to remove yourself from responsibility for how the new owner uses it. Once the DMV processes the form, you are no longer liable for parking tickets, traffic violations, accidents, or other incidents involving that vehicle — even if the new owner never registers it in their name.

The form is officially called the Notice of Transfer and Release of Liability (Form REG 138). It protects you by creating an official record that you no longer own the vehicle on a specific date. Without it, the DMV may continue to send you notices for violations or unpaid fees tied to the car, and you could face collection action for debts you did not incur.

This form is not the same as a bill of sale or a title transfer. You file it separately, and it works even if the buyer never completes their own registration. The release takes effect on the date you submit it, not the date the new owner registers the vehicle.

Key Takeaways

  • You must file Form REG 138 with the DMV within 5 days of selling or transferring your vehicle to protect yourself from liability for the new owner's violations and unpaid fees.
  • The form removes you from the DMV's records as the registered owner and stops the agency from sending you notices tied to that vehicle.
  • You can file the form online through the DMV website, by mail, or in person at a DMV office.
  • If you sell the vehicle to a private buyer and they never register it, filing the release form is your only protection against being held responsible for their violations.
  • Dealers and auction houses file their own releases automatically, but private sellers must file the form themselves.

When You Must File a Liability Release

You should file a liability release whenever you sell or give away a vehicle, regardless of whether the buyer is a private person, a dealer, or a family member. The timing matters: California law requires you to file within 5 days of the sale. Filing late does not invalidate the form, but it leaves you exposed to liability during the gap.

If you sell to a licensed dealer or auction house, they typically file the release on your behalf as part of their intake process. You can confirm this by checking your DMV record online a few weeks after the sale. If the vehicle still shows under your name, contact the dealer or file the form yourself when ready.

If you sell to a private buyer or give the vehicle away, you are responsible for filing. This is especially important if the buyer delays registering the vehicle or never registers it at all. Without the release form, you remain the registered owner in the DMV system and will receive notices for any violations, parking tickets, or registration fees the new owner incurs.

How to File Form REG 138 Online

The fastest way to file is through the California DMV website. Go to dmv.ca.gov and look for the "Register a Vehicle" section, then select "Report a Sale of Vehicle." You will need the vehicle's license plate number or VIN, the date of sale, and the buyer's name and address (if known).

The online form takes about 5 minutes to complete. You do not need to upload documents or provide a signature — the DMV accepts electronic submissions. After you submit, you will receive a confirmation number. Keep this number for your records. The DMV processes online submissions within 1 to 2 weeks, though the release takes effect on the date you file, not the date they process it.

If you do not have the buyer's full information, you can still file. Enter what you know — the sale date, vehicle details, and the buyer's name if you have it. The form will still protect you even if some fields are incomplete.

Filing by Mail or In Person

If you prefer to file by mail, print Form REG 138 from the DMV website, fill it out by hand or type, and mail it to the address listed on the form. Include a copy of the bill of sale or any document showing the sale date. Mail processing takes 2 to 4 weeks, so file as soon as possible after the sale.

You can also file in person at any DMV office. Bring the completed form, your ID, and proof of the sale (bill of sale, receipt, or written agreement showing the date). There is no fee to file a liability release. Processing at the office is when ready — you will receive a stamped copy confirming the DMV received your form.

If you are filing in person and do not have Form REG 138 with you, DMV staff can provide a blank copy or help you fill one out on the spot. This is often the fastest option if you want confirmation the same day.

What Happens After You File

Once the DMV processes your release form, the vehicle is removed from your registration record. You will no longer receive notices, renewal reminders, or violation citations tied to that vehicle. If a notice arrives after you have filed, it means the DMV has not yet processed the form — contact them with your confirmation number to verify receipt.

The new owner must still register the vehicle in their name to legally drive it. The liability release does not transfer the title or complete the registration process. If the buyer never registers the vehicle and it is later involved in an accident or violation, your release form protects you from being sued or held liable, because the DMV record shows you transferred ownership on a specific date.

Keep a copy of the filed form and your confirmation number indefinitely. If a debt collector or court later contacts you about the vehicle, you can provide proof that you filed the release within the legal timeframe.

Common Mistakes to Avoid

The most common mistake is waiting too long to file. If you sell a vehicle on a Monday and do not file until the following Monday, you have missed the 5-day window. While late filing does not invalidate the form, it leaves you vulnerable during those extra days. File within 24 hours of the sale if possible.

Another mistake is assuming the buyer will file the release for you. Private buyers have no obligation to file anything on your behalf. Only licensed dealers and auction houses file automatically. If you sell to a private person, you must file the form yourself.

Do not rely on a bill of sale alone. A bill of sale is a contract between you and the buyer, but it does not notify the DMV. The DMV only removes you from the vehicle record when you file Form REG 138. Without it, you remain the registered owner in their system.

Finally, do not assume the vehicle is off your record just because you sold it. Check your DMV record online a few weeks after filing to confirm the vehicle no longer appears under your name. If it still does, contact the DMV with your confirmation number.

What to Do If You Did Not File Within 5 Days

If you sold a vehicle more than 5 days ago and have not filed a liability release, file when ready. The 5-day important date is a guideline, not a hard cutoff — you can still file late and the form will protect you going forward. The release takes effect on the date you file it, so any violations or fees that occurred before you filed may still be your responsibility, but you are protected from that point onward.

If you have already received a notice or citation for the vehicle after the sale, include a copy of your bill of sale with the liability release form when you file. This creates a paper trail showing when you sold the vehicle and when you notified the DMV. If the DMV or a court questions the timing, you have documentation.

If a debt collector contacts you about unpaid parking tickets or registration fees from before you filed the release, respond in writing with a copy of the filed liability release form and your confirmation number. This proves you notified the DMV of the sale and are no longer responsible for the vehicle.

Frequently Asked Questions

Do I need to file a liability release if I sell to a car dealer?

Licensed dealers file the release automatically as part of their intake process, so you do not need to file it yourself. However, verify this by checking your DMV record online 2 to 3 weeks after the sale. If the vehicle still shows under your name, contact the dealer and file the form yourself when ready.

What if I do not know the buyer's name or address?

You can still file the form with just the vehicle information and sale date. The DMV does not require the buyer's details to process a liability release. Enter what you know and leave the buyer information blank if necessary.

Can I file a liability release if I lost the title?

Yes. The liability release does not require the title document. You only need the vehicle's license plate number or VIN and the sale date. If you need a replacement title later, you can request one separately from the DMV.

How long does it take for the release to show up in my DMV record?

Online filings take 1 to 2 weeks. Mail filings take 2 to 4 weeks. In-person filings are processed when ready. The release protects you on the date you file, even if the DMV has not updated their system yet. Check your record online after 2 weeks to confirm the vehicle is no longer listed.

What if the buyer registers the vehicle in their name but then abandons it?

Once the buyer registers the vehicle in their name, the DMV record transfers to them and you are no longer responsible, regardless of what happens to the vehicle later. Your liability release protects you from the date you filed it forward.
