Selling a vehicle in California can feel like a big puzzle—forms, smog, fees, and signing rules. This guide walks you through the exact steps and paperwork so you can sell a vehicle safely and correctly.

First, picture the common problem

Imagine you meet a buyer, they hand you money, and you shake hands. Later you get letters about tickets, a parking fine, or the DMV says the car is still in your name. The most common reason is missing paperwork, wrong signatures, or a missed transfer report.

So the goal is simple
Make the sale legal, document everything, and report the change on time.

Private sale checklist in California

Below is the “do it in order” plan that matches what most sellers must handle.

Core tasks and the forms that match them

Task What you do Form(s) that matter
Prove ownership Use the title you have or replace it REG 227
Make the ownership change official Fill in the ownership transfer section correctly Title / REG 227, REG 262 (if needed)
Report the sale to DMV Submit the seller notice quickly REG 138
Smog check rules Get smog only if your car needs it STAR smog certificate, REG 139
Confirm mileage correctly Disclose odometer reading when required Odometer disclosure (on title or REG 262)
If needed, create proof of sale Bill of sale when required by the situation REG 135

What forms are required to sell a car privately in California

In most private sales, you’ll rely on:

Document Who uses it Notes
California title Seller and buyer Use legal names, no nicknames; ink must be clear
REG 227 Used when title is missing (duplicate/paperless/transfer use) Includes lienholder release needs in certain cases
Transfer fee Applies as part of the DMV process FFVR 34
REG 262 Often required to transfer reassignment and may include odometer Vehicle/Vessel Transfer and Reassignment
REG 138 Seller Notice of Transfer and Release of Liability
Smog documentation Seller STAR station smog certificate if required
Odometer disclosure Seller Required for many newer model years
Bill of Sale Sometimes needed REG 135

Smog certification requirements for selling in California

Not every vehicle needs a smog check for a private transfer. The rule depends on the vehicle type and model year.

When you likely need smog

  • When a gas car is more than four model years old (and the sale triggers the requirement), the seller generally must obtain a smog certification from a STAR station.
  • If the car is a diesel, rules also depend on model year and weight category.

Smog usually not needed when

  • The car is four or fewer model years old
  • The vehicle fits common exemptions such as
  • electric-powered
  • natural-gas powered
  • motorcycles
  • certain older gas/diesel combinations

What “STAR” means

A smog certificate must come from a STAR station. A STAR station is approved for California emission testing and is the place that issues the official proof you may need.

Question Answer
Where do I get the smog certificate At a STAR smog testing station
How long is it valid 90 days
Why it matters Without it, the buyer can’t finish the DMV transfer correctly

What fees and taxes happen in California and who pays

Different costs show up depending on where the sale happens and the vehicle details. But one theme stays consistent: many of the ongoing DMV-type costs are paid by the buyer.

Common cost buckets

Cost type Typical payer Why
Transfer and registration-related fees Often buyer Buyer must register in their name
Taxes such as use tax Often buyer Based on the purchase price and local rules
Smog testing cost Seller if smog is required Seller must obtain STAR smog certification when applicable

Even if the buyer is the one paying most DMV costs, you still need to plan so the sale doesn’t stall on smog or missing paperwork.

How to complete and sign ownership transfer forms in California

A correct signing process prevents the biggest headaches.

Signature basics

  • Use legal names exactly as shown on documents.
  • Write clearly using black or blue ink.
  • Avoid corrections that look messy. Mistakes can cause delays.

Special note about REG 262

REG 262 is the Vehicle/Vessel Transfer and Reassignment form. It’s commonly used for reassignment and may be tied to odometer disclosure for the transfer process. It’s not just “extra paperwork”—it’s part of making the transfer clean.

Odometer disclosure rules when selling

California requires odometer disclosure for many newer model years.

Key points:
- For vehicles model year 2011 or newer, odometer disclosure is required for private vehicle transfers under the updated federal timeframe noted for 2021–2030.
- Cars older than 2010 are exempt from odometer disclosure.

What to do in practice

  1. Read the odometer carefully.
  2. Record the exact number.
  3. Put it on the odometer disclosure portion required by the transfer forms.

If the car is newer and you forget mileage disclosure, it can slow the buyer’s DMV process and create disputes.

Reporting the transfer to the DMV

Reporting is different for sellers and buyers.

Timeline

Person Deadline What you submit
Seller within 5 calendar days Notice of Transfer and Release of Liability (REG 138)
Buyer within 10 days reporting their DMV transfer application/payment process

Why it matters

Submitting the REG 138 helps protect you from problems after the sale, like liability tied to the car’s use after the transfer date.

When is a Bill of Sale required

A Bill of Sale (REG 135) is required in specific situations, especially when the seller is not the owner named on the title.

Simple rule

  • If the person signing the paperwork is not the exact titled owner, you may need a Bill of Sale signed by both parties to prove the sale agreement.

Also, it can help as extra proof for your records even when not strictly required.

Personalized and special license plates

License plates can be confusing, so here’s the clear idea:

Plate type Who owns it after the sale
Standard license plates that are tied to the vehicle transfer process Usually stay with the vehicle as part of typical transfer
Personalized or special interest plates Belong to the plate owner, not the car

That means your plate decision affects what you keep versus what the buyer gets.

How California residents sell to a dealership

Selling to a dealership is simpler than private selling because the dealer handles more steps.

How it usually differs from private sale

Topic Private sale Dealership sale
Paperwork handling You and the buyer The dealership guides and manages the transaction
Listing/search hassle You must advertise No need to list the vehicle yourself
Smog and transfer friction Can be on you Dealer usually coordinates required steps

A common example is trading in or selling directly to a dealership in the Los Angeles area.

Trading in a vehicle and sales tax

When you trade in your current vehicle and buy another one in the same transaction, you typically pay sales tax on the difference rather than the full price.

That means the trade-in value can lower the taxable amount for the new purchase.

Selling a car with an outstanding loan

If there’s a loan, the process can still work, but you must deal with the lienholder’s paperwork.

What you need to plan for

  • Make sure the lienholder provides release documents so the buyer can complete the title/transfer correctly.
  • The loan does not automatically stop a private sale, but it changes the documents you must have.

What paperwork do you need for a private sale

Here’s the full private-sale “paper trail” in plain language:

Category Paperwork
Ownership Title, or REG 227 if title missing
Transfer reassignment REG 262 when required
Smog STAR smog certificate if your car needs it
Mileage Odometer disclosure when required
Proof of sale Bill of Sale REG 135 if needed
Liability protection REG 138 within 5 days
Fixing errors REG 101 if there’s a title name error
Title/lien handling Lien release paperwork if there’s a loan

How long do you have to submit paperwork after selling

  • Seller: submit REG 138 within 5 calendar days.
  • Buyer: submit their DMV transfer process within 10 days.

Missing these windows increases the chance that your name still appears connected to the car.

Notice of Transfer and Release of Liability

The Notice of Transfer and Release of Liability (REG 138) is one of the most important documents for protecting you after the sale.

Why it is important

It releases you from civil or criminal liability for things like parking, abandonment, or operation after the transfer date.

What could happen without it What REG 138 helps prevent
Tickets or violations linked to you Liability after the transfer date

Keep a copy for your own records.

Where can you find the value of your used car

Before listing, you need a reasonable value range. Common options include:
- online trade-in valuation tools
- Kelley Blue Book value tools
- Edmunds True Market Value

The goal is not to guess—it’s to price the car so buyers take you seriously.

Common places sellers use include:
- Craigslist
- Facebook Marketplace
- AutoTrader

Tip
Use clear photos and a detailed description to reduce messages and time-wasters.

Steps before a buyer test drives your car

Test drives can be normal—but safety matters.

Practical steps

  1. Agree on the test drive time and location.
  2. Before driving, take photos or copies of the buyer’s driver’s license and proof of insurance.
  3. Don’t hand over keys unless paperwork and safety basics are done.

REG 262 in simple terms

REG 262 is the Vehicle/Vessel Transfer and Reassignment form used in California to complete the transfer process when required.

You’ll see it especially when:
- reassignment is needed for the ownership change
- odometer disclosure must be handled as part of the transfer process
- the title situation requires reassignment steps

Selling a car to a dealership vs selling privately

Here is the core difference in one view.

Factor Private sale Dealership sale
Convenience More steps for you Typically less work for you
Time Can take longer Often faster
Paperwork stress You manage most forms Dealer often handles paperwork
Tax impact Sale is separate Trade-in can change the tax calculation

Benefits of selling to a dealership in real life

Many sellers choose dealerships because it reduces risk and effort. For example, a dealership may:
- handle most paperwork
- coordinate inspection steps
- guide the loan/lien situation

This is often easier than trying to manage everything alone while strangers message you online.

Important exemptions for smog checks

Some vehicles are exempt from California’s smog requirement, such as:
- electric-powered vehicles
- natural-gas powered vehicles
- motorcycles
- certain older vehicles based on year and fuel type
- cars under four model years old (in many transfer situations)

How to decide what to do first

If you’re staring at your driveway thinking “What now?”, use this order:

  1. Confirm ownership documents and title status
  2. Check whether smog is needed at a STAR station
  3. Gather transfer forms including REG 262 when required
  4. Plan for odometer disclosure for newer model years
  5. Complete signatures cleanly
  6. Submit REG 138 within 5 days
  7. Keep copies of everything

That sequence prevents the most common mistakes that delay the DMV transfer and create legal stress.
