What a Release of Liability Does and Why You Need It
A Release of Liability is a form you file with the California Department of Motor Vehicles (DMV) to tell them you no longer own a vehicle. Once filed, you are no longer responsible for traffic tickets, accidents, or parking violations that happen after the sale — even if the new owner doesn't register the car in their name right away. Without this form, the DMV will keep sending notices to you for anything that happens to that vehicle.
California law requires you to file this form within 5 days of selling your car. If you don't and the new owner gets a ticket or is in an accident, you could be held liable. The form protects you from liability and also stops the DMV from billing you for registration renewal on a car you no longer own.
Key Takeaways
- You must file a Release of Liability with the California DMV within 5 days of selling your vehicle to avoid being held responsible for future violations or accidents.
- The form is called the Notice of Transfer and Release of Liability (Form REG 138) and can be filed online, by mail, or in person at a DMV office.
- You need the buyer's name and address, the vehicle identification number (VIN), the odometer reading, and the sale date to complete the form.
- Filing online through the DMV website is the fastest method and provides when ready confirmation that your release was received.
- If you sell to a private buyer who delays registration, filing this form protects you from liability for their driving during that gap.
The Form You Need: REG 138
The official form is called the Notice of Transfer and Release of Liability, also known as Form REG 138. This is the only form the DMV accepts for this purpose. You can get it three ways: read it from the California DMV website (dmv.ca.gov), pick it up at any DMV office, or request it by mail.
The form asks for basic information: your name and address, the buyer's name and address, the vehicle's VIN, the odometer reading at the time of sale, the sale date, and your signature. You do not need the buyer's signature on this form — it is your declaration that you sold the vehicle.
Three Ways to File Your Release of Liability
Online filing is the fastest option. Go to dmv.ca.gov, select "Register a Vehicle" or "Transfer Ownership," and look for the option to file a Release of Liability. You will enter the information from your sale documents directly into the form. The DMV will send you a confirmation email when ready, and you have proof of filing right away. This method works if you have the buyer's address and the sale date.
Mail filing takes longer but requires no trip to an office. Fill out Form REG 138 by hand or print it from the DMV website, sign it, and mail it to the address listed on the form (usually the DMV office in your county). Include a copy of the bill of sale if you have one. Mail typically takes 1 to 2 weeks to arrive, plus another 1 to 2 weeks for the DMV to process it. Keep a copy for your records.
In-person filing at a DMV office gives you a receipt on the spot. Bring the completed Form REG 138, your driver's license, and the vehicle's registration. You can file at any DMV office in California, not just the one in your county. Wait times vary by location, but you walk out with proof that the form was received.
What Information You Must Have Ready
Before you file, gather the documents from your sale. You need the buyer's full name and mailing address — this is the most important piece. If you sold to a dealer, use the dealer's business address. If you sold privately, get the buyer's home address. You also need the vehicle's VIN (from the registration or title), the odometer reading on the day of sale, and the exact date you sold the car.
If you do not have the buyer's address, you can still file the form with what you know and leave that field blank, though the DMV prefers the complete information. Some sellers photograph the buyer's driver's license to have the address on file, which is a practical step if you are selling privately.
The 5-Day Window and What Happens If You Miss It
California law gives you 5 calendar days from the sale date to file the Release of Liability. This is a hard important date, not a guideline. If you sell on a Monday, you have until the following Saturday to file. Weekends and holidays do not extend the important date.
If you file late, you remain liable for violations and accidents involving that vehicle until the form is processed. If the new owner gets a speeding ticket or is in an accident, the citation or claim can still come to you. Filing even one day late does not erase your liability retroactively — you are responsible for anything that happened between the sale and the filing date. The best practice is to file within 1 or 2 days of the sale, not wait until day 5.
What Happens After You File
Once the DMV receives and processes your Release of Liability, you will no longer receive registration renewal notices for that vehicle. The DMV will update its records to show you as the former owner. You should receive a confirmation letter in the mail within 2 to 4 weeks, though online filing gives you when ready confirmation.
Keep this confirmation or your receipt for at least 3 years. If a ticket or accident from that vehicle shows up on your record after you have filed the release, you can use the confirmation to prove you filed on time and are not responsible. Some buyers delay registering the vehicle, and during that gap, violations can still be issued under the old registration. Your Release of Liability protects you from those violations.
Special Situations: Dealers, Trade-Ins, and Private Sales
If you sell to a licensed dealer or trade in your vehicle, the dealer handles the Release of Liability filing on their end. You do not need to file it yourself. However, if the dealer does not file within 5 days, you are still liable. Ask the dealer for a receipt or confirmation that they have filed the release. If you do not hear back, file it yourself to be safe.
If you sell privately, you are responsible for filing. Do not rely on the buyer to file it — they have no obligation to do so, and many buyers delay registration for weeks or months. File the form yourself within 5 days, regardless of whether the buyer has registered the vehicle yet. This is the only way to protect yourself.
Frequently Asked Questions
What if I sold the car but don't have the buyer's address?
You can still file the Release of Liability with the information you have. Leave the buyer's address field blank if necessary, and include any other details you do have. The DMV prefers complete information, but an incomplete filing is better than no filing. If you later get the address, you can file an updated form.
Can I file a Release of Liability if I already sold the car months ago?
Yes, file it when ready. You are liable for anything that happened between the sale date and the filing date, but filing now stops future liability. The sooner you file, the sooner you are protected going forward. Bring documentation of the sale date if you have it.
Do I need the buyer's signature on the Release of Liability form?
No. This is your declaration to the DMV that you sold the vehicle. The buyer does not sign it. You only need your own signature and the information about the buyer and the vehicle.
What if the buyer never registers the car and I get a ticket in their name?
If you have filed the Release of Liability on time, you can dispute the ticket by providing proof of the filing date. The DMV record will show you are no longer the owner. Contact the court or the agency that issued the ticket and provide your Release of Liability confirmation. You may need to appear or submit a declaration, but the filing protects your case.
Is there a fee to file a Release of Liability?
No, filing a Release of Liability is free. There is no charge whether you file online, by mail, or in person at a DMV office.
