California requires you to transfer title within 10 days of purchase, and you do it through the Department of Motor Vehicles using a signed pink slip and proof of sale

The pink slip — officially the Certificate of Title — is the document that proves ownership. When you buy a car in California, the seller signs the back of their pink slip and gives it to you. You then take that signed slip, along with proof of purchase and a completed process form, to the DMV or submit it by mail. The DMV processes the transfer, issues a new pink slip in your name, and registers the vehicle to you.

The 10-day important date is not a suggestion. If you miss it, you can still transfer the title, but you may face late fees and the vehicle remains registered to the previous owner during that gap — which creates liability problems if the car is involved in an accident or a traffic violation.

You have three ways to complete the transfer: in person at a DMV office, by mail, or through an authorized third party like a car dealership or a DMV-approved service. Each route has different timelines and document requirements.

Key Takeaways

  • You must submit the signed pink slip, a completed process for Title or Registration (Form REG 343), and proof of purchase to the DMV within 10 days of buying the car.
  • The seller must sign the back of the pink slip in the designated owner signature area; a notary is not required in California.
  • You will need to pay a title transfer fee, which varies based on the vehicle's value and whether you are transferring from an individual or a dealer.
  • If the seller cannot locate the pink slip, you can request a duplicate from the DMV, but this adds time and cost to the process.
  • Out-of-state titles must be submitted along with a smog certification (if the car is subject to California emissions standards) before the DMV will issue a California title.

What documents you need to bring or submit

The Certificate of Title (pink slip) is the foundation. It must be signed by the previous owner in the owner signature area on the back. If there are two owners listed, both must sign unless one has already signed and the other is transferring their interest to you. If the title is lost or damaged, the seller can request a duplicate from the DMV using Form REG 227, but this takes additional time.

You also need proof of purchase. For a private sale, this is usually a bill of sale — a straightforward document showing the buyer, seller, vehicle details, sale price, and date. California does not have a required bill of sale form, but the DMV accepts any written record that shows these details. If you bought from a dealer, the dealer's paperwork serves as proof of purchase.

Complete Form REG 343 (process for Title or Registration). You can read this from the California DMV website or pick one up at any DMV office. Fill in your name, address, the vehicle identification number (VIN), and the odometer reading. If you financed the car, you will also need to list the lienholder (the bank or lender).

If the car is from out of state, you will need a smog certification from a California-certified smog station. California requires this for most vehicles before issuing a title, even if the car passed smog in another state. Bring the smog certificate with your other documents.

In-person transfer at a DMV office

Walking into a DMV office with all documents in hand is the fastest route if you have a clear title and no complications. Bring the signed pink slip, completed Form REG 343, proof of purchase, and your identification. If the car is financed, bring the lien documentation as well.

The DMV will verify the documents, collect the transfer fee, and issue you a temporary registration document on the spot. The new pink slip arrives by mail within two to three weeks. You can drive the car legally on the temporary registration until the permanent title arrives.

Wait times at DMV offices vary widely by location and time of day. Many offices now offer online appointment scheduling, which can cut your wait from hours to 15 minutes. Check the California DMV website for your local office's hours and whether appointments are available.

Transferring by mail

If you cannot visit a DMV office, you can mail your documents directly. Send the signed pink slip, completed Form REG 343, proof of purchase, and a check or money order for the transfer fee to the DMV address listed on the form. Include a copy of your identification and a phone number where the DMV can reach you if there are questions.

Processing by mail typically takes four to six weeks from the date the DMV receives your package. There is no way to track the status of a mailed transfer in real time, so plan accordingly if you need the new title quickly. If the DMV finds an error or missing document, they will contact you, which adds another week or two to the timeline.

Use certified mail with return receipt so you have proof the DMV received your documents. Keep copies of everything you send.

Using a dealership or DMV-authorized service

Many car dealerships and independent DMV services (sometimes called title services or registration services) will handle the transfer for you. They charge a fee — usually $50 to $150 on top of the DMV's transfer fee — but they handle the paperwork and submission. This is common when you buy from a dealer, as they often include this service in the sale.

If you use a third party, you still need to provide the signed pink slip, proof of purchase, and your identification. The service submits everything to the DMV on your behalf. Turnaround time is similar to in-person DMV service — you receive a temporary registration when ready and the permanent pink slip by mail within two to three weeks.

Make sure any service you use is DMV-authorized. The California DMV website lists authorized representatives by county. Unauthorized services may delay your transfer or submit incomplete paperwork.

Transfer fees and what affects the cost

California's title transfer fee depends on the vehicle's value and whether you are transferring from a private party or a dealer. For a private sale, the fee is based on the sale price you report. For a dealer sale, the fee is based on the dealer's selling price.

As of 2024, the base transfer fee ranges from roughly $15 to $70 depending on the vehicle value, but this varies. You will also pay a registration fee, which is calculated based on the vehicle's value and weight. The DMV website has a fee calculator where you can enter your vehicle details and get an exact quote.

If you are financing the car, there is an additional lien fee. If the car is from out of state, there may be a smog certification fee (charged by the smog station, not the DMV). If the title is damaged or the seller cannot locate it, a duplicate title fee applies.

What to do if the seller cannot find the pink slip

If the seller has lost or damaged the pink slip, they can request a duplicate from the DMV using Form REG 227 (process for Duplicate or Paperless Title). The seller must submit this form with proof of ownership (such as registration or insurance documentation) and pay a duplicate title fee. The DMV will mail a replacement pink slip to the seller's address on file, which typically takes two to three weeks.

Once the duplicate arrives, the seller signs it and gives it to you, and you proceed with the normal transfer process. This adds time to your purchase, so ask the seller to request the duplicate as soon as possible after you agree to buy the car.

In rare cases where the seller is unavailable or unwilling to cooperate, you may need to file for a title transfer without the original pink slip. This requires filing Form REG 343 with a statement explaining why the title is unavailable. The DMV will investigate and may contact the previous owner. This process takes significantly longer — often six to eight weeks — and is not recommended unless there is no other option.

Out-of-state title transfers and smog requirements

If you are moving to California with a car titled in another state, you must transfer that title to California within 20 days of establishing residency. The process is similar to a private sale transfer, but with an additional requirement: smog certification.

California requires a smog test for most vehicles before issuing a California title. The test must be performed by a California-certified smog station and the certificate must be current (usually valid for 30 days). Bring the out-of-state pink slip, the smog certificate, completed Form REG 343, and proof of residency (such as a utility bill or lease) to the DMV.

Some vehicles are exempt from smog testing — typically very new cars (current model year and one year prior) and certain older vehicles. Check the California DMV website to see if your vehicle qualifies for an exemption. If it does, you can skip the smog test and proceed directly to the title transfer.

Frequently Asked Questions

Do I need a notary to transfer a car title in California?

No. California does not require a notarized signature on the pink slip. The seller's signature on the back of the title is sufficient. However, if you are buying from an estate or there are complications with ownership, a notary may be helpful for other documents, but it is not required by the DMV for a standard title transfer.

What if I buy a car but the seller has not paid off their loan?

The lender's name will appear on the pink slip as the lienholder. You cannot take ownership until the loan is paid off and the lender releases their lien. Typically, the seller pays off the loan at the time of sale using the sale proceeds, and the lender sends a lien release to the seller or directly to the DMV. Ask the seller to provide proof that the lien has been released before you hand over payment. If the lien is not released, the title transfer will be rejected.

Can I drive the car before the new title arrives?

Yes. The DMV issues a temporary registration document (usually valid for 30 days) when you complete the transfer in person or through an authorized service. You can drive legally on this temporary document while you wait for the permanent pink slip to arrive by mail. If you transfer by mail, the DMV will include a temporary registration in their response.

What happens if I miss the 10-day important date?

You can still transfer the title, but you may face a late fee and the vehicle remains registered to the previous owner during the gap. This creates liability issues — if the car is involved in an accident or receives a traffic ticket, the previous owner may be held responsible. Transfer the title as soon as possible after purchase to avoid these complications.

Do I need to transfer the title if I am just adding a co-owner?

If you already own the car and want to add another owner, you do not need a full title transfer. Instead, you file Form REG 343 with the DMV requesting to add a co-owner. Both owners must sign the form. This is simpler than a full transfer and costs less. If you want to remove an owner, that also requires a form submission but not a complete title transfer.
