Regulation 343 covers the documents you must show when you register a vehicle or renew your registration

Regulation 343 is the California DMV rule that lists which documents prove ownership and identity during registration. You will need to present these documents in person or by mail depending on whether you are registering a new vehicle, renewing an existing registration, or transferring a title. The specific documents required depend on whether the vehicle is new, used, out-of-state, or inherited.

This regulation exists because the DMV must verify that the person registering the vehicle actually owns it and has the legal right to do so. Without these documents, the DMV cannot issue a registration certificate or renew one. Understanding what Regulation 343 requires before you visit a DMV office or submit documents by mail saves time and prevents your process from being delayed or rejected.

Key Takeaways

  • Regulation 343 requires proof of ownership, such as a title, bill of sale, or court order, depending on how you acquired the vehicle.
  • You must show a valid government-issued photo ID that matches the name on the ownership document.
  • If you are registering a vehicle purchased from a dealer, the dealer's paperwork must include the vehicle identification number and sale price.
  • Out-of-state vehicles require an out-of-state title or registration document in addition to California-specific forms.
  • If the registered owner and the person explore are different, you may need a power of attorney or notarized authorization.

Proof of Ownership Documents Under Regulation 343

The ownership document you bring depends on how you obtained the vehicle. If you bought it from a licensed dealer, bring the dealer's paperwork, which must show the vehicle identification number (VIN), the sale price, and the dealer's name and license number. If you bought it from a private party, bring a bill of sale signed by both the seller and buyer, or a completed REG 135 form (process for Title or Registration) with the seller's signature.

If you inherited the vehicle, bring a copy of the will or a court order showing you are the legal heir, along with a death certificate. If the vehicle was given to you as a gift, bring a signed gift letter from the previous owner that includes the VIN, the date of transfer, and both signatures. If you are registering a vehicle you already own in California but are renewing the registration, bring your current registration card or renewal notice.

For out-of-state vehicles, bring the out-of-state title or registration document in the name of the current owner. California will not issue a California title until the out-of-state document is surrendered to the DMV. If the out-of-state title is held by a lienholder (a bank or finance company), you may need a release of lien or a letter from the lienholder authorizing the transfer.

Identity and Residency Requirements

You must show a valid government-issued photo ID that matches the name on the ownership document. Acceptable forms of ID include a California driver's license, California ID card, passport, military ID, or tribal ID. The name on your ID must match the name on the title, bill of sale, or other ownership document exactly. If your name has changed since the ownership document was issued, bring a marriage certificate, divorce decree, or court order showing the name change.

You must also prove California residency. Regulation 343 requires proof that you live in California, such as a utility bill, lease agreement, mortgage statement, or bank statement dated within the last 60 days and showing your current address. If you recently moved to California, bring the document that shows your new address. If you do not have a document in your name, you may bring a document in a household member's name along with a signed statement explaining your living situation.

When the Registered Owner and Applicant Are Different People

If the person whose name is on the title is not the person explore for registration, Regulation 343 requires written authorization. This happens when a spouse, adult child, or attorney is handling the registration on behalf of the owner. The owner must sign a power of attorney form (usually REG 260) or a notarized letter authorizing the other person to act on their behalf.

The authorization document must include the vehicle identification number, the owner's signature, the date, and the name and signature of the person authorized to act. If the owner is deceased and the vehicle is being registered by an heir or executor, bring a court order or will instead. The DMV will not accept verbal authorization or an unsigned letter.

Documents for Vehicles with Liens

If the vehicle is financed and the lender holds the title, Regulation 343 allows you to register the vehicle in your name, but the lender's name will appear on the registration as the lienholder. You must bring the loan agreement or a letter from the lender showing the vehicle identification number and the lender's name and address. Some lenders provide a document called a lienholder authorization that you bring to the DMV.

If you are paying off the loan and want to remove the lien, wait until the loan is fully paid and you receive the title free and clear from the lender. Then bring that title to the DMV to register the vehicle without a lienholder. Do not attempt to register a vehicle with a lien unless you have the lender's written authorization or the loan agreement in your possession.

Common Documents You Will Need to Bring

In addition to the ownership and identity documents described above, Regulation 343 typically requires the following:

  • A completed REG 343 form or the appropriate process form for your situation (such as REG 135 for a new title or REG 14 for registration renewal).
  • Proof of California residency, such as a utility bill or lease dated within 60 days.
  • Proof of vehicle inspection if the vehicle is out-of-state or has been out of state for more than one year.
  • Smog certification if the vehicle is subject to California emissions testing.
  • Payment for registration fees, which vary based on the vehicle's value and type.

If you are registering the vehicle by mail, make copies of all documents and keep the originals. The DMV will return some original documents (such as out-of-state titles) by mail after processing. Do not send cash; use a check or money order made payable to the California Department of Motor Vehicles.

What Happens if Documents Are Missing or Incorrect

If you submit an process without all required documents, the DMV will send you a notice listing what is missing. You will have a set number of days (usually 30) to provide the missing documents before the process is denied. If you submit documents with errors—such as a misspelled name or incorrect VIN—the DMV may reject the process and ask you to correct them.

If a document is damaged, illegible, or appears to be altered, the DMV may request a replacement or a certified copy from the issuing agency. For example, if your bill of sale is water-damaged and the VIN is not readable, you may need to contact the seller and request a new signed bill of sale. Bringing all documents in clear, legible condition the first time prevents delays.

Frequently Asked Questions

Do I need the original title or can I bring a copy?

For out-of-state titles, you must bring the original because the DMV will keep it. For California titles, you may bring a copy if the original is lost, but you will need to request a duplicate title from the DMV first. For bills of sale and other documents, copies are usually acceptable if they are clear and legible.

What if the seller's name on the bill of sale does not match the title?

This is a red flag for the DMV and may delay or prevent registration. Contact the seller and ask them to clarify or provide a corrected bill of sale. If the seller cannot be reached, you may need to contact the DMV to discuss your options, as this could indicate a title problem.

Can I register a vehicle if I do not have a California address yet?

No. Regulation 343 requires proof of California residency before registration. If you are moving to California, you can register the vehicle once you have a lease, utility bill, or other proof of your new address. Some people register out-of-state vehicles temporarily and then transfer them to California after establishing residency.

What if the vehicle was a gift and the previous owner will not sign the bill of sale?

A signed gift letter from the previous owner is the standard document for a gifted vehicle. If the previous owner refuses to sign anything, contact the DMV to discuss your options. You may be asked to provide additional documentation or a statement explaining the situation.

Do I need a notary for the power of attorney?

Some power of attorney forms must be notarized, while others do not. Check the specific form the DMV requires for your situation. If you are unsure, contact your local DMV office or check the DMV website before you visit.
