Complete Guide: Everything You Need To Know About The California DMV Bill Of Sale
Navigating vehicle transactions in California can be daunting, especially when dealing with the paperwork required by the Department of Motor Vehicles (DMV). A Bill of Sale is a crucial legal document that acts as a receipt and a record of the transfer of ownership between a buyer and a seller. While California is unique in its documentation requirements, understanding exactly how to handle the Bill of Sale can save you from potential legal headaches and financial losses down the line.
The primary purpose of a Bill of Sale in California is to provide a clear, written record of the transaction. It documents the vehicle’s identity, the names and addresses of both parties, the purchase price, and the date of sale. While the California DMV provides a specific form (REG 135), understanding the nuances of how and when to use it is essential for both private sellers and buyers.
Why You Need a Valid California DMV Bill of Sale
In the eyes of the California DMV, a transfer of title is the ultimate proof of ownership, but a Bill of Sale serves as the bridge between the initial agreement and the formal title transfer. If a vehicle is involved in a hit-and-run, a toll violation, or an abandoned vehicle report shortly after the sale, a properly executed Bill of Sale proves that you were no longer the legal owner. Without it, you might find yourself liable for damages or fees incurred by the new owner.
Furthermore, the California DMV requires a Bill of Sale to calculate use tax accurately. When a vehicle is purchased, the state assesses a tax based on the purchase price stated in the documentation. If the paperwork is missing, inconsistent, or lacks specific details, the DMV may estimate the vehicle's market value, which often results in a significantly higher tax bill for the buyer than what was actually paid for the vehicle.
Finally, having a signed Bill of Sale provides peace of mind. It serves as an audit trail. If there are future disputes regarding the condition of the vehicle at the time of sale, or if the buyer claims there were hidden liens, the Bill of Sale acts as the baseline agreement. Ensuring that both the buyer and seller possess a copy is a fundamental step in conducting a secure, transparent vehicle transaction in the Golden State.
Official California DMV Form REG 135 Explained
The California DMV form REG 135 is the standard template used for vehicle transfers. While you are not strictly required to use the DMV-provided form—you may draft your own as long as it contains the required information—using the official document is highly recommended. The official form is designed to capture every piece of data the DMV clerks need to process the title transfer without delays or requests for additional documentation.
The form requires specific information to be valid, including the Vehicle Identification Number (VIN), the Make, the Model, the Year, and the Odometer reading at the time of sale. Accuracy here is non-negotiable. An incorrect VIN digit can stall a registration process for weeks. Always verify the VIN on the physical vehicle dashboard or the door jamb rather than relying solely on the title document, as typos on older titles are surprisingly common.
Beyond the vehicle specs, the form mandates the full names, physical addresses, and signatures of both the buyer and seller. This is not merely a formality; it is a legal requirement to ensure that both parties are clearly identified. In cases where there are multiple owners listed on the title, all registered owners must sign the Bill of Sale to make the transfer valid. Failing to get all required signatures is one of the most common reasons for rejected DMV paperwork.

Comparison: Bill of Sale vs. Title Transfer
It is vital to distinguish between a Bill of Sale and the Certificate of Title. A Bill of Sale is a record of the transaction, whereas the Title (the "Pink Slip") is the actual instrument of ownership transfer. You cannot complete a vehicle transfer with a Bill of Sale alone; the Title must be signed over to the buyer. The Bill of Sale is essentially the supporting documentation that facilitates the title transfer process.
| Feature | Bill of Sale (REG 135) | Certificate of Title (Pink Slip) |
|---|---|---|
| Primary Function | Proof of sale/transaction record | Official proof of legal ownership |
| Legal Requirement | Required for tax purposes and record | Mandatory for all ownership transfers |
| Who Keeps It? | Buyer and Seller keep copies | Buyer submits to DMV for new title |
| Data Included | Price, date, signatures, odometer | VIN, owner history, lienholder info |
| Issuing Agency | California DMV/Private Parties | California DMV exclusively |
As shown in the table above, the two documents serve distinct roles. The Title is the "Master Key" to the vehicle. If you buy a car without the Title, you are not buying the car; you are buying a problem. A Bill of Sale cannot replace a missing Title, although it may be used as part of a "Bonded Title" process if the original title is lost and the seller is unreachable—a process that is notoriously expensive and time-consuming in California.
Steps to Complete a Legal Vehicle Sale in California
To initiate a sale, both parties must first agree on the terms. Once the price is settled, the seller must provide the buyer with the Certificate of Title, ensuring the odometer reading is clearly marked. If the vehicle is less than 10 years old, the odometer reading must be disclosed to ensure compliance with federal and state truth-in-mileage laws.
Next, both parties should complete the REG 135 form. This is best done in person at the time of the money exchange. Do not sign the Bill of Sale before the vehicle is physically inspected or before funds are verified. Cashier’s checks are generally preferred over personal checks for high-value sales to prevent fraud. Once the documents are signed, the seller must remove their license plates (unless they are personalized plates they intend to surrender) and file a "Notice of Transfer and Release of Liability" (NRL) with the DMV.
Filing the NRL is the most critical step for the seller. This can be done online through the California DMV website. By submitting this notice, the seller informs the DMV that they are no longer in possession of the vehicle. This protects the seller from any parking tickets, traffic violations, or accidents that occur after the date of sale. If you do not file this, you remain the "owner of record" and will be held responsible for the vehicle's future actions.
Frequently Asked Questions (FAQ)
Do I need a notary for a California Bill of Sale?
No, the state of California does not require a Bill of Sale to be notarized for standard vehicle transfers. The signatures of the buyer and seller are sufficient for the DMV, provided the paperwork is accurate and complete.
Can I write my own Bill of Sale?
Yes, you can draft your own document. It must include the date of sale, the purchase price, the full names and addresses of both parties, a description of the vehicle (Year, Make, Model, VIN), and the signatures of both the buyer and seller.
What happens if I lose the Bill of Sale?
If you have already transferred the title, the Bill of Sale is less critical. However, if the registration is stalled, you may need to reach out to the seller to sign a duplicate or a replacement REG 135 form to verify the transaction details.
Do I need a Bill of Sale for an out-of-state car?
Yes. When bringing a vehicle into California from another state, the DMV will require documentation of the purchase, which includes a Bill of Sale and the previous state’s title, as well as a VIN verification conducted by a DMV official or licensed vehicle verifier.
How much does it cost to process the paperwork?
The cost depends on the vehicle's purchase price and the county where it is being registered, as California uses a complex formula for registration and use taxes. You should check the DMV’s "Vehicle Registration Fee Calculator" online to get an estimate.
