Selling a car in California is mostly about one thing: getting the paperwork right. The state’s DMV keeps your name attached to a vehicle until the transfer is properly recorded, so a missing signature or a skipped form can leave you dealing with parking tickets, tolls, or other issues connected to the vehicle after the sale. The good news is that the list of documents to sell a car in California is short and predictable once you know what’s required, what’s optional, and how to handle the tricky cases. Here’s the full checklist, based on current California DMV requirements.
The documents you’ll almost always need
For a standard private sale, four things do most of the work:
- The California Certificate of Title, signed by you to release ownership
- An odometer reading recorded at the time of sale
- A valid smog certificate (in most cases)
- A Notice of Transfer and Release of Liability filed with the DMV within five days
Everything else – a bill of sale, a duplicate title application, a lien release – depends on your specific situation. Let’s walk through each piece.
The car title (your most important document)
The car title, sometimes called the pink slip, is the legal proof of ownership and the centerpiece of the sale. To transfer it, you sign the release-of-ownership line (Line 1) on the title and hand it to the buyer. If there’s more than one registered owner and their names are joined by “and,” every owner has to sign; if the names are joined by “or” or “and/or,” one signature is enough.
The odometer reading usually goes right on the title. If your title doesn’t have a line for it, you’ll record the mileage on a Vehicle/Vessel Transfer and Reassignment (REG 262) form instead. That form is printed on secure paper and is not available as a regular download, so it must be requested from the DMV or obtained through an authorized source. Most newer vehicles require the reading; only quite old vehicles are exempt from the federal disclosure requirement.
One California-specific note: your license plates stay with the car. Standard sequential plates transfer to the new owner, so you don’t peel them off (special-interest or personalized plates are the exception and can be retained).
Release of liability – the step sellers skip most
If you remember only one form, make it this one. The Notice of Transfer and Release of Liability (DMV form REG 138, often called the NRL) tells the state you no longer own the car. California law requires you to file it within five calendar days of the sale, and you can do it online through the DMV in a couple of minutes.
This is what protects you. Once the DMV processes the release of liability, anything the new owner racks up after the sale date – tickets, fines, civil claims – becomes their responsibility, not yours. Handing over a signed title alone does not do this. Only the DMV filing does.
Two things worth understanding: filing the NRL does not transfer ownership (only the buyer’s title application removes your name from the record), and you’ll need a few basics to complete it – the plate number, VIN, sale date, odometer reading, and the buyer’s name and address. The record typically updates within one business day.
Smog certificate – when you need one and when you don’t
In most cases, the seller has to provide the buyer with a valid smog certificate at the time of sale, and it’s only good for 90 days from the date it’s issued. But there are several common exemptions where you won’t need one:
- Gasoline vehicles four model years old or newer. Instead of a smog check, an $8 smog transfer fee applies (typically paid by the buyer at registration).
- Vehicles from model year 1975 and older, which are exempt from smog inspection entirely.
- Electric vehicles, and certain diesel vehicles (generally model year 1997 and older, or with a gross vehicle weight rating over 14,000 pounds).
- A recent biennial smog check – if you submitted a smog certificate to the DMV within 90 days before the transfer, you can sign a statement instead of getting a new one.
When in doubt, confirm your vehicle’s status with the DMV, since the cutoffs are based on model year, fuel type, and weight.
Bill of sale – recommended, sometimes required
A bill of sale (DMV form REG 135) records the sale price, date, vehicle details, and both parties’ information. It isn’t always mandatory for a basic transfer, but it becomes required when the person selling the car isn’t the registered owner on the title. Even when it’s optional, it’s smart paperwork: it documents what was agreed and gives both sides a clean record if a question comes up later.
Edge cases worth planning for
Selling a financed car
If you still owe money, the lender is the legal owner on the title and has to release its interest before ownership can pass cleanly to the buyer. That release can come on the title itself once the loan is paid, or through a Lien Satisfied/Title Holder Release (REG 166) form. Because the timing of the payoff and the lien release is the part that trips people up, it’s worth reading how loan payoff works when selling a financed car before you start.
Lost or missing title
You don’t need to track down your original pink slip to sell. If the title is lost, stolen, or damaged, you complete an Application for Replacement or Transfer of Title (REG 227) and use it in place of the title to finish the sale. One catch: if there’s a lienholder on record, the lien-release section of the REG 227 must be notarized – and if the vehicle is two model years old or newer and still has a lienholder, you can’t use the REG 227 at all and must get a replacement title through the lender instead.
You’re not the registered owner
Selling on behalf of a family member, an estate, or anyone else means extra documentation – typically a bill of sale signed by both you and the person named on the title, and often a Statement of Facts (REG 256) for gifts or family transfers. The REG 262 reassignment form may also come into play if the car has changed hands more than once on the same title.
Your quick California seller’s checklist
Before you hand over the keys, make sure you have:
- The signed Certificate of Title (or a REG 227 if it’s lost)
- The odometer reading recorded on the title or a REG 262
- A valid smog certificate, unless your vehicle is exempt
- A bill of sale (required if you’re not the registered owner, recommended otherwise)
- A lien release if the car was financed
- The Notice of Transfer and Release of Liability filed within five days of the sale
Get those squared away and the buyer can complete their side of the transfer – they have 10 days to do so – without anything bouncing back to you.
