Buying a Car Private Party in California: The Checklist

Mo G
Last verified: September 14, 2026

The car looks clean, the price is fair, and the seller wants cash today. That is the moment most California private party deals go wrong, because almost every expensive mistake in a used car purchase is made in the ten minutes before money changes hands, not after.

In California, a private party car purchase runs on two clocks: you have 10 days to transfer the title into your name, and the seller has 5 days to file a release of liability. The seller must hand you a valid smog certificate. Sticker Quicker, a licensed California DMV Business Partner, can file the whole transfer for you without a DMV visit.

The short version: what to check before you pay

1. The name on the title matches the government ID of the person selling the car.
2. You are holding the actual California Certificate of Title, not a photocopy and not a promise.
3. No lienholder is printed on the title, or the lienholder has released it in writing.
4. The seller has a passing smog certificate in hand, unless the car is under four model years old.
5. You have a written odometer reading if the car is less than 10 years old.
6. You know what the registration status is, because unpaid fees follow the car, not the seller.

If any one of those six is missing, the deal is not ready. Walk, or fix it before you pay.

Check one: does the name on the title match the seller?

This is the single most common private party disaster, and it has a name in the trade: a jumped title. Someone bought the car, never registered it, and is now reselling it with the previous owner’s signature still the only one on the document.

The California DMV is explicit about the fix. If the seller is not the owner whose name is on the title, you need a Bill of Sale signed by both the seller and the person whose name appears on the title. Without that second signature, your chain of ownership has a hole in it, and DMV will not complete the transfer.

The practical rule: ask to see the seller’s driver license and compare it to Line 1 of the title, letter for letter, before any money moves. A nickname, a maiden name, or a spouse’s name is not a match.

When the title says “and” between two names

If two owners are joined by “and” on the title, both must sign. If they are joined by “or”, either one can. People miss this constantly, and a title missing a required signature is a title that cannot be transferred.

Check two: is there a lienholder on the title?

If a bank or credit union is printed on the title as legal owner, that lender still has a claim on the car. The seller cannot transfer clean ownership until the lien is released, which DMV handles through a Lien Satisfied / Title Holder Release (REG 166).

There is a second, sharper consequence most buyers never hear about. If the title is also missing and you have to use the replacement path, DMV requires section 5 of the Application for Replacement or Transfer of Title (REG 227) to be notarized when the record shows a legal owner or lienholder. If the registration shows no lienholder, no notarization is required. That one detail decides whether your Saturday involves a notary.

Check three: the smog certificate is the seller’s job, not yours

Definition: a smog certification is the electronic record a licensed California smog station transmits when a vehicle passes its emissions inspection. DMV will not complete a transfer without one where it is required.

California DMV states the rule plainly on its Smog Inspections page: “If you are selling your car, you need to give the new owner a valid smog certification when you sell the car.” The cost and the hassle belong to the seller. A seller who says “you can smog it yourself after” is asking you to absorb a repair bill of unknown size.

There is one carve-out. If the car is less than four years old, no smog inspection is needed, and the buyer pays a smog transfer fee of $8 instead, under Vehicle Code section 4000.1.

Which cars need no smog inspection at all

Per the same DMV page, a vehicle does not need a smog inspection if it is:

• Gasoline powered and a 1975 year model or older, including motorcycles and trailers
• Diesel powered and a 1997 or older year model, or with a gross vehicle weight over 14,000 pounds
• Powered by natural gas and over 14,000 pounds
• An electric vehicle
• Gasoline powered and less than eight model years old

A live inconsistency worth knowing about. That same DMV page, last modified June 23, 2026, publishes the new vehicle rule two different ways. The exemption list above says “less than eight model years old.” The FAQ on the page says that since January 1, 2019, a vehicle “less than 4 model years old” can pay a smog abatement fee instead of testing, “for the first 8 years that your vehicle is registered.” And the seller transfer rule uses a four year threshold. If your car sits anywhere near those lines, confirm with DMV before you assume you are exempt rather than relying on any single sentence, including this one.

What you must walk away with

DMV’s private party registration page, last modified August 7, 2026, lists exactly what a buyer needs to take over ownership:

1. The title, signed by the seller on Line 1. If it has been lost, stolen, or damaged, you need a REG 227 instead.
2. A Bill of Sale signed by both parties if the seller is not the person named on the title.
3. An odometer reading if the vehicle is less than 10 years old. If the title has no line for mileage, you need a Vehicle/Vessel Transfer and Reassignment (REG 262), signed by both buyer and seller.
4. A smog certification.
5. The fees and the use tax.

One warning about the REG 262: it is not downloadable. DMV prints it on security paper to satisfy federal odometer disclosure rules, so you cannot grab it online at 9 p.m. the night before. You request one through DMV’s automated line at 1-800-777-0133, or you work with a licensed Business Partner who already has them.

The two deadlines

DMV’s Title Transfers and Changes page puts it in one line: any change in ownership or lienholder must be reported to DMV within 10 days, and the title must be updated. Once filed, a new title usually arrives by mail in 15 to 30 days.

What a private party transfer actually costs

That last row is the one that ruins budgets. Registration debt attaches to the vehicle, not to the person who ran it up. California’s penalty schedule reaches 60 percent of the vehicle license fee once payment is 31 days to one year late, and 160 percent past two years, plus flat registration and CHP late fees. A $3,000 car with three years of unpaid registration is not a $3,000 car. Ask the seller for the current registration card and check the expiration date before you agree on a price.

Where to file the transfer

The Virtual Office row is the one that surprises people who last bought a car in 2024. Online title transfer is gone. If you want to avoid a field office, a licensed Business Partner is now the practical route. You can start a California title transfer with Sticker Quicker without setting foot in a DMV.

You already bought it. Now what?

The title is missing

Use the REG 227. If DMV’s record shows a lienholder, section 5 needs a notary. One hard stop: if the registration card reads “Nontransferable / No California Title Issued,” a REG 227 will not work, and you must obtain a title from the state where the vehicle was last titled.

The seller was not the person on the title

You need a Bill of Sale signed by the seller and by the titled owner. If you cannot reach the titled owner, you have a genuine chain of ownership problem, and it is worth getting help before you spend more money on the car.

The car will not pass smog

Here is the part almost no buying guide tells you, and it is the strongest argument for making the seller smog the car. California’s three smog relief programs all exclude a vehicle that is changing hands.

• The Bureau of Automotive Repair’s CAP repair assistance requires that your vehicle “must not be undergoing a transfer of ownership.”
• All three CAP vehicle retirement tiers carry the same disqualifier.
• The Smog Check Referee’s Repair Cost Waiver states that a vehicle is disqualified if it “is undergoing change of ownership or initial registration in California.”

Translated: buy a car that fails smog, and you personally are on the hook for the entire repair bill, with no state assistance available to you on that transaction. The seller, who still owned the car when it failed, was the one who could have applied. That is why “I’ll smog it myself” is an expensive sentence.

There are unpaid registration fees

They are now yours. Pay them, and get the transfer filed so the penalty clock stops. If the car also needs a smog certificate before DMV will release the registration, a licensed Business Partner can often post fees and move the file forward while you sort the smog out. Sticker Quicker has handled this for more than 500,000 customers, and catching it early is what keeps a bad purchase from turning into a suspended registration.

Frequently asked questions

How long do I have to transfer a car title in California after buying it?

Ten days. California DMV gives buyers 10 days after purchasing a vehicle to transfer ownership from the seller to themselves. Filing late adds a $15 transfer penalty under Vehicle Code section 9553.7, on top of the $15 transfer fee. The seller separately has 5 days to file a release of liability.

Does the seller have to provide a smog certificate in California?

Yes. California DMV states that if you are selling your car, you must give the new owner a valid smog certification when you sell it. The exception is a vehicle less than four years old, where no inspection is required and the buyer instead pays an $8 smog transfer fee under Vehicle Code section 4000.1.

What if the seller’s name is not on the title?

You need a Bill of Sale signed by both the seller and the person whose name appears on the title. California DMV requires this whenever the seller is not the owner named on the title. Without that second signature the chain of ownership is broken and DMV will not complete the transfer.

Can I transfer a California car title online?

No. California DMV stopped accepting online title transfer requests through its Virtual Office on September 20, 2025. Your options today are a DMV field office, mail to Sacramento, or a licensed California DMV Business Partner such as Sticker Quicker, which files the transfer without a DMV visit.

Do unpaid registration fees transfer to me when I buy the car?

Yes. Registration debt follows the vehicle, not the previous owner. California penalties reach 60 percent of the vehicle license fee at 31 days to one year late and 160 percent past two years, plus flat registration and CHP late fees. Check the registration card’s expiration date before agreeing on a price.

What is a REG 262 and why can I not download it?

The Vehicle/Vessel Transfer and Reassignment (REG 262) records odometer and transfer information when the title has no mileage line. DMV prints it on security paper to comply with federal odometer disclosure regulations, so it is not available online. Request one at 1-800-777-0133 or through a licensed Business Partner.
