DMV REG 135 PDF Guide: Avoid Paperwork Nightmares

Selling or buying a used vehicle in California should be an exciting milestone, but an administrative oversight at the Department of Motor Vehicles can quickly turn the experience into an ordeal. One of the most essential documents in private-party transactions is the California Bill of Sale. Downloading and correctly executing the DMV reg 135 pdf is often the critical step that protects both parties from tax disputes, title transfer stalls, and liability headaches.

Whether you are parting with an old commuter car, buying a motorcycle, or transferring a vessel, this guide covers everything you need to know about California Form REG 135—what it is, how to fill it out accurately, and how to avoid the simple mistakes that send drivers back to the DMV waiting line.

What Is California DMV Form REG 135?

Form REG 135 is the official State of California Department of Motor Vehicles Bill of Sale. It establishes a legal record that ownership of a vehicle or vessel has transferred from one party to another on a specific date for a specific financial consideration (or as a gift).

While the vehicle’s certificate of title (the pink slip) remains the ultimate proof of legal ownership, the bill of sale acts as secondary documentation to establish:

• The exact sale price for calculating state use tax.
• The precise date ownership changed hands.
• The identities, contact details, and signatures of both buyer and seller.
• Legal proof of purchase when the existing title is missing an explicit bill of sale section.

When Do You Need the DMV REG 135 PDF?

Not every vehicle transaction demands a standalone bill of sale, but having a completed copy is standard protective practice. Specifically, you will need the DMV reg 135 pdf under the following circumstances:

• No dedicated sale space on the title: Older California titles or out-of-state certificates often lack dedicated fields for purchase price and buyer signatures.
• The vehicle is transferred as a gift or trade: When money does not change hands or the vehicle is an inheritance, REG 135 allows you to declare the transfer type legally so the buyer avoids improper taxation.
• Multiple buyers or sellers: If there are multiple registered owners releasing interest or multiple buyers taking ownership, REG 135 provides clear, structured space to record every party.
• Vessel or trailer transfers: The form covers watercraft, utility trailers, and standard motor vehicles alike.
• Personal record keeping: Both parties should retain a copy to resolve potential disputes over parking tickets, toll violations, or vehicle condition after the date of sale.

REG 135 vs. REG 262: An Important Distinction

Many drivers confuse Form REG 135 with Form REG 262 (Vehicle/Vessel Transfer and Reassignment Form). Understanding the difference can save you an unexpected trip to a physical DMV branch:

• REG 135: Publicly accessible online, free to download as a standard PDF, and printable at home. It functions strictly as a Bill of Sale.
• REG 262: Printed on security paper to prevent fraud. It includes a power of attorney section and federal odometer disclosure. You cannot download REG 262 online. If your transaction requires an odometer reading for a vehicle under 20 model years old and you do not have the original title, you must pick up a physical REG 262 from a DMV office or licensed registration service.

Step-by-Step: How to Fill Out Form REG 135

Filling out the REG 135 is straightforward, but errors or illegible handwriting can cause processing rejections. Follow this section-by-section breakdown to complete it correctly.

Section 1: Vehicle / Vessel Identification

Accuracy here is mandatory. Gather the registration card or physical vehicle identification to enter the following details:

• License Plate or CF Number: Enter the current California license plate number (or CF number for watercraft).
• Vehicle Identification Number (VIN) or Hull Identification Number (HIN): Cross-check this number directly against the metal VIN plate on the vehicle's dashboard or door jamb, not just previous paperwork.
• Year, Make, and Model: Enter the manufactured year, brand (e.g., Toyota, Ford), and model description.

Section 2: Bill of Sale (Transaction Details)

This section sets the financial parameters of the deal for the California Department of Tax and Fee Administration (CDTFA):

• Sale Amount: State the exact purchase price in dollars and cents. Never artificially deflate this number; the DMV audits unrealistic transaction values against market averages.
• Gift or Trade: If no money changed hands, check the box indicating it was a gift or an even trade. Enter the estimated market value where indicated.
• Date of Sale: Write the exact day the physical handover took place. This date sets the deadline for transfer notices and liability protection.

Section 3: Buyer and Seller Information

Both parties must supply verifiable identity details:

• Print full legal names clearly (First, Middle, Last). Avoid abbreviations.
• Provide permanent physical addresses (DMV will reject forms that list only an unverified P.O. Box without a residence address).
• Include contact telephone numbers and driver’s license numbers for identification verification.

Section 4: Signatures

The form is void without valid signatures. Both the seller (releasing interest) and the buyer (acknowledging receipt) must sign and date the document. If two individuals co-own the vehicle and their names are joined by "and" on the title, both owners must sign the REG 135.

Common REG 135 Mistakes That Trigger Delays

A simple clerical error can halt a vehicle registration transfer for weeks. Beware of these frequent pitfalls:

1. Using White-Out or Crossing Out Text: The DMV will generally reject titles or supplemental forms containing correction fluid, erased figures, or heavy strike-throughs. If you make a mistake, print a fresh PDF and begin again.
2. Mismatched Dates: Ensure the date written on REG 135 matches the date entered on the original title and the Notice of Transfer and Release of Liability.
3. Incomplete VINs: Most modern passenger vehicles have 17-character VINs. Missing a single digit or transposing "8" and "B" will trigger an automatic system error.
4. Forgetting to Print Dual Copies: Once signed, immediately make a physical photocopy or digital scan. The buyer submits the original to the DMV; the seller must keep a signed copy in their personal files.

The Critical Next Step for Sellers: Notice of Release of Liability

Filling out Form REG 135 proves the sale, but it does not automatically notify the state that you no longer own the vehicle. In California, sellers are legally required to file a Notice of Transfer and Release of Liability (Form REG 138) within 5 calendar days of the sale.

Failing to submit this release can leave you legally responsible if the buyer runs toll booths, receives parking tickets, or gets into an accident before transferring the title. You can file Form REG 138 instantly online through the California DMV portal using the information recorded on your completed REG 135.

Frequently Asked Questions

Does California Form REG 135 require notarization?

No. Standard California vehicle and vessel sales using Form REG 135 do not require a notary seal. A handwritten signature from each party is sufficient under state law.

Can I use Form REG 135 to replace a lost title?

No. A Bill of Sale records a transaction, but it does not convey legal ownership on its own if the title is lost. If the title is missing, the seller must submit an Application for Duplicate or Paperless Title (Form REG 227) alongside the transfer paperwork.

Where can I get an authentic DMV REG 135 PDF?

Always download the document directly from the official California DMV website (dmv.ca.gov) to ensure you are using the most current revision of the form without paying third-party fees.
