Buying a used car is exciting. The paperwork is less exciting, but in California it is where most of the mistakes happen. A missing signature on the title, an expired smog certificate or a missed deadline can turn a good deal into weeks of back-and-forth with the DMV.
This guide walks through what actually changes hands when you buy a used car in California, who is responsible for what, and roughly what you will pay. We have kept it general on purpose: fees and rules change, so for exact numbers we point you to the official California DMV pages and its fee calculator.
Quick summary: The seller signs the California Certificate of Title (the “pink slip”) over to you, provides a smog certificate for most gas cars and files a Notice of Transfer and Release of Liability. You then submit the paperwork and pay the transfer fee, use tax and any registration fees due to the DMV within 10 days.
The California Certificate of Title (“pink slip”)
The Certificate of Title proves who owns the car. Before you pay, look at it carefully:
- The VIN matches the car. Compare the 17-character VIN on the title with the VIN on the dashboard (visible through the windshield) and the door-jamb sticker.
- The seller’s name matches. The person or business selling the car should be the registered owner on the title, or have the paperwork showing they acquired it.
- Lienholder. If a bank or lender is listed as legal owner, the loan must be paid off and the lender must release its interest (they sign the title or issue a lien release) before the title can transfer to you.
- Title brands. Words like salvage, junk, rebuilt, flood or lemon law buyback matter a lot for value and insurance. A vehicle history report and the federal NMVTIS title check at vehiclehistory.bja.ojp.gov can confirm what you see.
At the sale, the seller signs the title as the registered owner, the odometer reading is recorded, and you sign as the new owner. Signatures in the wrong box or crossed-out information can cause the DMV to reject the paperwork, so take your time.
If the title is lost: the seller should apply for a replacement or a transfer using DMV form REG 227 (Application for Replacement or Transfer of Title) before or as part of the sale. Do not hand over the full amount for a car whose ownership cannot be documented.
The smog certificate
For most gasoline-powered vehicles, California makes the seller responsible for providing a valid smog certification when ownership changes. Smog certificates are only valid for a limited time, so ask when the inspection was done and check that it is still current at the time of sale.
There are exemptions. According to the DMV, a smog inspection is not required for, among others:
- Electric vehicles (no tailpipe, no smog check),
- Gasoline vehicles from model year 1975 or older,
- Certain older or heavy diesel and natural-gas vehicles,
- Newer gasoline vehicles within the first model years, where a smog transfer or abatement fee may be charged instead of an inspection.
The rules for newer cars and family transfers have specific details, so check the official DMV smog inspections page for your exact vehicle. Smog Check stations are licensed by the Bureau of Automotive Repair.
The Notice of Transfer and Release of Liability (seller’s job)
Within 5 days of the sale, the seller should submit a Notice of Transfer and Release of Liability (NRL) to the DMV. It can be done online and needs the buyer’s name and address, the plate number, the last five digits of the VIN and the odometer reading.
The NRL protects the seller from parking tickets, tolls and liability after the date of sale. It is not a title transfer. As the DMV itself notes, the new owner still has to complete the transfer and pay the fees. As a buyer, expect the seller to ask for your full name and address for this form — that is normal.
Your part: transferring ownership within 10 days
The DMV says any change in ownership must be reported within 10 days. To transfer the title into your name you typically need:
- The signed California Certificate of Title (or REG 227 if the title was lost).
- A smog certificate, unless the vehicle is exempt.
- Odometer disclosure, usually recorded on the title itself for vehicles that require it.
- A bill of sale when needed — for example, if the purchase price is not written on the title. The DMV form is REG 135 (Bill of Sale).
- Statement of Facts (REG 256) for special situations, such as a family transfer, a gift or to explain a correction.
- Payment of the transfer fee, use tax and any registration fees due.
You can submit at a DMV field office, by mail, or through a DMV business partner in some cases. The DMV says a new title usually arrives by mail within about 15–30 days. Keep copies of everything you sign and submit until it does.
If the car comes from another state, the process includes extra steps such as a vehicle verification (form REG 31). The DMV has a separate checklist for out-of-state title transfers on its title transfers page.
What does it cost? DMV fees and use tax
This is the part where people most want a single number, and it is the part where a single number is most likely to be wrong. What you pay depends on the car, its price, where you live and where the registration currently stands. In broad terms:
| Item | What it is | Who usually pays |
|---|---|---|
| Transfer fee | DMV fee to put the title in your name | Buyer |
| Use tax | California’s tax on a vehicle bought from a private party, based on the purchase price and your local tax rate | Buyer, paid to the DMV |
| Registration fees | Any registration that is due or expiring, plus vehicle license fee and county/district fees | Buyer (if registration is current, some of it may already be paid) |
| Smog certificate | Inspection at a licensed Smog Check station | Seller, for most gas cars |
| Smog transfer / abatement fee | Charged for some newer vehicles instead of an inspection | Buyer |
| Penalties | For late transfer or late registration | Whoever missed the deadline |
Electric and zero-emission vehicles also pay an additional road improvement fee at registration for newer model years.
The DMV’s official fee calculator will estimate your total for a specific vehicle. The DMV also explains each charge on its registration fees page. Run the calculator before you buy so the out-the-door cost is not a surprise.
Buying from a dealer vs. a private party vs. an independent seller
The paperwork underneath is similar, but who does it varies:
- At a franchised or large dealership, the dealer usually submits the transfer and registration for you and collects the tax and fees as part of the deal, along with their own documentation fees.
- In a private-party sale, you and the seller handle everything yourselves: signing the title, the smog certificate, the NRL, and your visit (or mail-in) to the DMV.
- With an independent seller like us, the goal is to make the private-party process feel organized: the documents are prepared before you arrive, every signature is in the right place, and the government charges you will pay are written down for you to check.
Whatever route you take, ask for the total, out-the-door cost in writing before you hand over money.

Frequently asked questions
How long do I have to transfer a title after buying a used car in California?
The California DMV says a change of ownership must be reported within 10 days. In practice that means the buyer submits the signed title, the transfer application and the fees within 10 days of the sale. Waiting longer can add penalties.
Who pays for the smog check when buying a used car in California?
For most gasoline vehicles the seller is responsible for providing a valid smog certificate at the time of sale. Some vehicles are exempt, including electric vehicles and older or very new model years. Check the DMV smog inspection page for the current rules for your car.
Do I pay sales tax when buying a used car from a private seller in California?
Generally, yes, in the form of use tax, which the buyer pays to the DMV when transferring the title. The amount depends on the purchase price and the tax rate where the car will be registered. The DMV fee calculator gives an estimate.
What is a Notice of Transfer and Release of Liability?
It is the seller's notice to the DMV that the car has been sold. It must be submitted within 5 days and protects the seller from tickets and liability after the date of sale. It does not transfer ownership; the buyer still has to complete the title transfer.
What if the seller does not have the title?
The seller needs to apply for a replacement or transfer title first, using DMV form REG 227. Be cautious about paying in full before the paperwork that proves ownership is in order.
