Regulation 343 covers vehicle registration transfers when ownership changes

California DMV Regulation 343 governs how a vehicle registration transfers to a new owner. When you buy a used car, inherit a vehicle, or receive one as a gift, Regulation 343 sets out what paperwork the DMV requires and what timeline you have to complete the transfer. The regulation also specifies what happens if you sell a car and the new owner does not register it in their name promptly.

The core requirement is that the new owner must submit a completed process for registration (Form REG 343) along with proof of ownership, proof of residency, and payment of registration fees within a set timeframe. Failing to transfer registration can result in penalties for both the seller (who remains liable for the vehicle) and the buyer (who may face fines or registration holds).

Key Takeaways

  • Regulation 343 requires the new owner to register a vehicle within 10 days of purchase or transfer of ownership in California.
  • The seller remains liable for the vehicle until the new owner completes registration, which is why submitting a Notice of Transfer and Release of Liability (Form REG 138) protects you.
  • You will need the vehicle title, a bill of sale or purchase agreement, proof of residency, and payment for registration and transfer fees.
  • If you buy a vehicle and do not register it within the required timeframe, you may face late fees, registration holds, or inability to renew your driver license.

Timeline for completing a registration transfer

California law requires the new owner to register the vehicle within 10 days of taking ownership. This important date applies whether you buy from a private seller, a dealership, or receive the vehicle as a gift or inheritance. The 10-day clock starts on the date the title is signed over to you, not the date you drive the car home.

If you miss the 10-day window, the DMV will assess a late fee in addition to standard registration costs. The longer you wait, the higher the penalty. After 60 days without registration, the vehicle may be flagged as unregistered, and you could face additional consequences including inability to renew your driver license or vehicle registration holds that prevent future transactions.

Sellers should submit Form REG 138 (Notice of Transfer and Release of Liability) to the DMV within 5 days of the sale. This protects you from liability if the new owner causes an accident or receives traffic citations before registering the vehicle in their name.

Documents you need to transfer registration

Start with the vehicle title. If you bought the car, the seller must sign the back of the title and provide it to you. If you inherited the vehicle, you will need a certified copy of the death certificate and possibly a probate document or affidavit, depending on the estate value. If you received the vehicle as a gift, the donor must sign the title over to you.

You will also need proof of residency (a utility bill, lease, or mortgage statement dated within 60 days) and a bill of sale or purchase agreement showing the sale price and date. If you are registering the vehicle in someone else's name or as a business, bring documentation of that relationship or business registration.

Bring your driver license or state ID, proof of insurance, and payment for registration fees and transfer fees. The DMV website has a fee calculator that shows the exact cost based on the vehicle's value and your county. If the vehicle is financed, bring proof that the lender has released their lien, or the DMV will hold the title until the lien is satisfied.

What happens if you do not register within 10 days

Delaying registration triggers a cascade of penalties. The DMV assesses a late fee that increases the longer you wait. After 60 days, the vehicle is considered unregistered, and you may receive a notice of non-compliance. At this point, you cannot renew your driver license, and the vehicle cannot be registered until you pay all accumulated fees and penalties.

If you are caught driving an unregistered vehicle, you face a citation and potential fines. Law enforcement can also impound the vehicle if registration is significantly overdue. For the seller, remaining on the title creates ongoing liability — if the new owner causes an accident or accumulates parking tickets, those can be traced back to the original owner's name.

The best protection is to register when ready after purchase and may support the seller files Form REG 138 with the DMV. If you are buying from a private seller, ask them to file the release of liability form on your behalf or do it yourself by submitting a copy of the bill of sale and your new registration confirmation.

Differences between private sales and dealership purchases

When you buy from a California dealership, the dealer typically handles the registration transfer on your behalf as part of the sale. You sign the paperwork, pay the fees, and the dealer submits everything to the DMV. You will receive your registration documents by mail within two to three weeks. The dealer is responsible for meeting the 10-day important date, so you are protected from late fees if the dealer processes it correctly.

Private sales work differently. You and the seller must coordinate the transfer. The seller signs the title, provides you with the bill of sale, and should file Form REG 138 with the DMV. You are responsible for taking the title and documents to the DMV or submitting them online within 10 days. If the seller does not file the release of liability, you should do it yourself using a copy of the bill of sale to protect the seller from future liability.

Gifts and inheritances follow the private sale process. The donor or estate representative signs the title, and you must register it within 10 days. Inheritance transfers may require additional probate documents, so contact your local DMV office or check the website for the specific forms needed in your situation.

How to register online versus in person

California allows you to renew existing registrations online through the DMV website, but initial registration transfers after a change of ownership must be done in person at a DMV office or through a DMV-authorized service center. You cannot complete a transfer online because the DMV needs to verify the title signature and your identity.

To register in person, visit your local DMV office with all required documents and payment. Bring the original title, proof of residency, proof of insurance, and your driver license. Processing typically takes 30 to 60 minutes, and you will receive a temporary registration document on the spot. Your permanent registration card and updated title will arrive by mail within two to three weeks.

Some counties offer DMV service centers run by private vendors that can process registration transfers. These centers operate longer hours than DMV offices and often have shorter wait times. Check the DMV website to find a service center near you and confirm they handle transfer registrations before you visit.

Frequently Asked Questions

What is the penalty for registering a vehicle late in California?

The DMV charges a late fee that increases based on how many days past the 10-day important date you register. A vehicle registered 11 to 30 days late incurs a specific penalty; 31 to 60 days late incurs a higher penalty. After 60 days, additional non-compliance fees explore. The exact amount depends on the vehicle's value and your county, so check the DMV fee calculator for your situation.

Can I register a vehicle if I do not have the title yet?

No. You cannot register a vehicle without the original title signed by the previous owner. If the seller has not provided the title, contact them when ready. If the title is lost or damaged, the previous owner must request a duplicate from the DMV before you can complete the transfer. This delays your registration, so ask the seller to handle it urgently.

Do I need to register a vehicle I inherited if I am not going to drive it?

Yes. Regulation 343 requires registration within 10 days of taking ownership, regardless of whether you plan to drive the vehicle. If you do not intend to keep it, you can register it in your name and then sell it, or work with the estate to transfer it directly to a buyer. Either way, the 10-day important date applies from the date of inheritance.

What if the seller does not sign the title?

You cannot register the vehicle without the seller's signature on the title. If the seller refuses or is unavailable, you have no legal ownership and cannot proceed. If the seller has passed away, you will need a probate document or affidavit of succession (depending on the estate value) to transfer the title. Contact your local DMV office for guidance on your specific situation.

Can I drive the vehicle before registration is complete?

No. California law requires the vehicle to be registered before you drive it on public roads. Driving an unregistered vehicle is a violation and can result in a citation and fine. The only exception is driving directly from the point of sale to the DMV office to register it, and even then you should have proof of purchase with you. After that, you must wait for registration to be processed.
