What Documents Do You Need to Buy a Used Car in Washington State?
Buying a used car in Washington is not just about finding the right vehicle — it’s also about handling the paperwork correctly. Without the proper documents, you may face delays in registration, hidden legal issues, or even risk losing your money.
Here’s a complete checklist of the documents you need when buying a used car in Washington.
1. Vehicle Title (Certificate of Ownership)
The title proves who legally owns the car. When you buy a used vehicle, the seller must sign the title over to you.
- Check that the VIN on the title matches the car.
- Make sure there are no liens (unpaid loans) listed.
- Both buyer and seller must sign the title.
2. Bill of Sale
While not always mandatory, a Bill of Sale is highly recommended. It records the transaction and protects both parties.
It usually includes:
- Buyer and seller names & addresses
- Vehicle details (make, model, year, VIN)
- Sale price and date
- Signatures
In Washington, you can also use the official form available from the WA Department of Licensing (DOL).
3. Odometer Disclosure Statement
Federal law requires an odometer reading disclosure if the car is under 10 years old.
- This is often included on the back of the title.
- Both parties must sign to confirm the mileage is correct.
4. Vehicle Report of Sale
The seller must file a Vehicle Report of Sale with the DOL within 5 days of selling the car. This protects them from future liability. As a buyer, check that the seller completes this step.
5. Emissions and Safety Requirements
In most of Washington, emissions testing is no longer required (the program ended in 2020). However, it’s still wise to ask for recent maintenance records or inspection reports to ensure the car is safe to drive.
6. Insurance Proof
Before you can register and drive the car, you need valid auto insurance in your name. Arrange coverage before transferring ownership.
7. Registration and License Plates
After the purchase, you must register the car in your name at your local licensing office within 15 days. Bring:
- Signed title
- Bill of Sale
- Proof of insurance
- Payment for taxes and fees
You can either transfer the existing plates (if eligible) or get new ones.
