How to Sell a Car in Washington State

Selling a car in Washington State is straightforward if you follow the right steps. You’ll need a completed title signed by both seller and buyer, a Bill of Sale, and a valid emissions test if required. Don’t forget to notify the DOL within 10 days of the sale to avoid liability—this simple step protects you from future fines or penalties.

Key Takeaways

• Gather all required documents: Title, registration, and bill of sale are essential for a legal sale.
• Complete the title transfer: Sign over the title and provide odometer disclosure to the buyer.
• Submit a Release of Liability: File online with the DOL to avoid future responsibility for the vehicle.
• Remove license plates: Keep your plates; Washington does not transfer them to the new owner.
• Provide a completed bill of sale: Include sale price, date, and both parties’ information for records.
• Notify your insurance company: Cancel or adjust coverage once the sale is complete.

How to Sell a Car in Washington State

So, you’ve decided it’s time to sell your car. Maybe you’re upgrading to something newer, downsizing to a more fuel-efficient model, or just ready to part ways with that trusty old sedan that’s seen better days. Whatever the reason, selling a car in Washington State doesn’t have to be stressful—or confusing. I remember when I sold my first car in Seattle a few years back. I was nervous, unsure of the paperwork, and honestly, a little overwhelmed by all the steps. But once I broke it down, it turned out to be smoother than I expected. And that’s exactly what I want to help you with today.

Whether you’re in Spokane, Tacoma, or somewhere in between, the process of selling a car in Washington follows a set of clear rules and best practices. The good news? Washington has a relatively straightforward system, especially compared to some other states. But there are still important details—like title transfers, emissions testing, and safety inspections—that you’ll want to get right to avoid headaches later. In this guide, I’ll walk you through every step of the process, from preparing your vehicle to handing over the keys (and the title) with confidence. We’ll cover everything you need to know to sell your car quickly, legally, and for the best possible price.

Understand Washington State’s Car Selling Requirements

Before you even list your car online or put up a “For Sale” sign in the window, it’s crucial to understand what Washington State requires when you sell a vehicle. Unlike some states, Washington doesn’t require a formal inspection for most private car sales, but there are still legal obligations you must meet. Skipping these can lead to fines, delays, or even legal trouble down the road.

Title Transfer Is Mandatory

The most important step in selling a car in Washington is transferring the title to the new owner. The title is the legal document that proves ownership, and without a proper transfer, you could still be held liable for the vehicle—even after it’s sold. When you sell your car, you must sign over the title to the buyer. This means filling out the “Assignment of Title” section on the back of the title certificate. Both you and the buyer should sign it, and the buyer will need it to register the car in their name.

One common mistake I’ve seen (and almost made myself) is forgetting to fill out the odometer reading. Washington requires this for vehicles under 10 years old. If your car is newer, make sure the mileage is clearly recorded. Also, if your title is lost, you’ll need to apply for a duplicate through the Washington Department of Licensing (DOL) before you can sell the car.

Bill of Sale: A Smart Backup

While Washington doesn’t legally require a bill of sale for private car transactions, it’s highly recommended. A bill of sale acts as a receipt and protects both you and the buyer. It should include:

• The vehicle’s make, model, year, and VIN
• The sale price
• The date of sale
• Signatures of both buyer and seller

You can download a free bill of sale template from the Washington DOL website. I always keep a copy for my records—just in case there’s ever a question about the transaction later.

Release of Liability: Protect Yourself

Here’s a step many sellers overlook: filing a release of liability. Once you sell your car, you need to notify the Washington DOL that you’re no longer responsible for it. This protects you if the buyer gets a ticket, parks illegally, or gets into an accident before registering the car.

You can file the release of liability online through the DOL’s website. It’s free and takes just a few minutes. Be sure to do this within 5 days of the sale. I learned this the hard way when a friend sold his truck and got a parking ticket in the mail two weeks later—because the new owner hadn’t registered it yet. Don’t let that happen to you.

Prepare Your Car for Sale

Now that you know the legal basics, it’s time to get your car ready to sell. First impressions matter—especially when it comes to cars. A clean, well-maintained vehicle will not only attract more buyers but also help you get a better price. Think of it like staging a house: you want it to look its best.

Clean Inside and Out

Start with a thorough cleaning. Wash the exterior, wax it if possible, and clean the windows inside and out. Don’t forget the wheels and tires—grime buildup can make a car look neglected. Inside, vacuum the carpets, wipe down surfaces, and remove any personal items. I once sold a car with a half-eaten sandwich under the seat—let’s just say the buyer wasn’t impressed. A little effort goes a long way.

If your car has minor scratches or dings, consider getting them touched up. You don’t need a full paint job, but a $50 touch-up kit can make a big difference. And if the interior has odors—especially smoke or pet smells—invest in an ozone treatment or professional detailing. A fresh-smelling car feels newer and more cared for.

Gather Maintenance Records

Buyers love seeing proof that a car has been well-maintained. Gather all your service records, receipts, and any documentation from oil changes, tire rotations, or major repairs. If you’ve kept up with regular maintenance, highlight that. For example, “Oil changed every 5,000 miles” or “New brakes installed in 2022” can boost buyer confidence.

I once sold a 2015 Honda Civic with a complete service history. The buyer was so impressed they offered $500 over my asking price. It wasn’t just the car—it was the peace of mind that came with knowing it had been cared for.

Address Minor Repairs

You don’t need to fix everything, but addressing small issues can increase your car’s value. Replace burnt-out bulbs, fix wiper blades, and top off fluids. If the check engine light is on, get it diagnosed. Even if it’s a minor sensor issue, buyers will assume the worst if it’s not addressed.

One tip: avoid major repairs unless they’re essential. For example, if your transmission is failing, it’s usually better to sell the car “as-is” rather than sink money into a repair that won’t significantly increase the sale price.

Determine the Right Price for Your Car

Pricing your car correctly is one of the most important steps in the selling process. Overprice it, and it’ll sit on the market for months. Underprice it, and you’ll leave money on the table. The key is to find that sweet spot where your car is competitive but still reflects its true value.

Research Comparable Listings

Start by checking online marketplaces like Kelley Blue Book (KBB), Edmunds, and Autotrader. Look for cars similar to yours in terms of year, make, model, mileage, and condition. Pay attention to listings in your area—prices can vary by region. For example, a used SUV might sell for more in rural areas where trucks are popular, while a compact car might do better in a city like Seattle.

I used KBB’s “Private Party Value” tool when selling my car. It gave me a range based on my vehicle’s condition (I chose “Good”), and I priced mine slightly below the top end to attract quick offers. It worked—I had three inquiries within 24 hours.

Factor in Condition and Extras

Be honest about your car’s condition. If it has high mileage, cosmetic flaws, or needs repairs, adjust the price accordingly. On the flip side, if your car has low mileage, new tires, or aftermarket upgrades (like a premium sound system), you can justify a higher price.

One thing to keep in mind: buyers often negotiate. So, it’s smart to price your car slightly above what you’re willing to accept. That way, you have room to come down without losing money. For example, if you want $10,000, list it at $10,500.

Consider Market Trends

The used car market can fluctuate based on supply, demand, and even the time of year. For instance, convertibles sell better in spring and summer, while SUVs and trucks are in higher demand in fall and winter. Also, keep an eye on gas prices—when fuel costs rise, fuel-efficient cars tend to sell faster.

In 2023, I noticed a spike in demand for hybrid vehicles in Washington due to rising gas prices and state incentives for eco-friendly cars. If you’re selling a hybrid or electric vehicle, you might be able to command a premium—especially if it qualifies for Washington’s EV tax credits.

Choose the Best Way to Sell Your Car

Once your car is clean, priced, and ready to go, it’s time to decide how to sell it. You have several options, each with pros and cons. The right choice depends on your priorities: speed, price, convenience, or control.

Sell Privately

Selling privately typically gets you the highest price. You’re dealing directly with the buyer, so there’s no middleman taking a cut. Platforms like Craigslist, Facebook Marketplace, and OfferUp are popular in Washington. I sold my last car on Facebook Marketplace—it was easy to list, and I reached a lot of local buyers quickly.

But private sales require more effort. You’ll need to create a detailed listing with photos, respond to inquiries, and meet potential buyers. Safety is also a concern. Always meet in a public place, bring a friend, and never hand over the keys until the payment is secure. I once met a buyer at a police station parking lot—just to be safe.

Trade-In at a Dealership

If convenience is your top priority, trading in your car at a dealership might be the way to go. You can apply the trade-in value toward a new vehicle, and the dealership handles the paperwork. It’s fast and hassle-free.

The downside? You’ll usually get less money than selling privately. Dealerships need to make a profit, so they’ll offer you less than market value. I traded in a car once and got $2,000 less than I would have selling it myself. But the trade-off was worth it—I saved time and avoided the stress of private negotiations.

Sell to a Car Buying Service

Companies like CarMax, Carvana, and Vroom offer quick, no-hassle sales. You get an online quote, schedule an inspection, and receive payment—often within a day. These services are great if you need to sell fast or don’t want to deal with strangers.

However, like trade-ins, you’ll likely get less than private sale value. I used Carvana once and got a fair offer, but it was still about 10% below what I estimated for a private sale. Still, the convenience made up for it.

Complete the Sale and Transfer Ownership

Congratulations—you’ve found a buyer! Now it’s time to finalize the sale and make sure everything is done correctly. This is where many sellers make mistakes, so pay close attention.

Accept Secure Payment

Never accept cash for large amounts—it’s risky and hard to trace. Instead, use a cashier’s check or bank transfer. If using a check, wait for it to clear before handing over the car. I once had a buyer offer a personal check, but I insisted on a cashier’s check from their bank. It took an extra 20 minutes, but it was worth the peace of mind.

Some buyers may want to pay in cash. If you must accept cash, meet at a bank and have the teller verify the amount and authenticity. Better yet, use a secure payment app like Zelle or Venmo—but only if you trust the buyer.

Hand Over the Title and Keys

Once payment is secured, sign the title over to the buyer. Make sure all required fields are filled out, including the odometer reading and sale price. Give the buyer the keys, any extra sets, and the owner’s manual. If you have service records, include those too.

Don’t forget to remove your license plates. In Washington, license plates stay with the seller, not the car. The buyer will need to get new plates when they register the vehicle. I made the mistake of leaving my plates on once—had to mail them back to the buyer later.

Notify the DOL and Cancel Insurance

After the sale, file your release of liability with the Washington DOL. This is critical—don’t skip it. Also, contact your insurance company to cancel or adjust your policy. You don’t want to keep paying for a car you no longer own. Most insurers will refund the unused portion of your premium.

Common Mistakes to Avoid When Selling a Car in Washington

Even with the best preparation, it’s easy to make mistakes. Here are a few common pitfalls and how to avoid them:

• Not transferring the title properly: Always sign the title correctly and ensure the buyer completes their part. A missing signature can delay registration.
• Forgetting the release of liability: This is a big one. File it within 5 days to avoid liability for the buyer’s actions.
• Overpricing the car: Be realistic. Use pricing tools and adjust based on condition and market demand.
• Meeting buyers in unsafe locations: Always meet in public, well-lit areas. Bring a friend if possible.
• Accepting risky payment methods: Avoid personal checks or wire transfers from unknown sources. Stick to cashier’s checks or bank transfers.

Final Tips for a Smooth Car Sale in Washington

Selling a car doesn’t have to be a headache. With the right preparation and knowledge, you can sell your vehicle quickly, legally, and for a fair price. Here are a few final tips to keep in mind:

• Take high-quality photos from multiple angles. Good lighting and a clean background make a big difference.
• Write a detailed, honest description. Mention any flaws upfront to build trust.
• Be responsive to inquiries. Quick replies increase your chances of a sale.
• Stay patient. Some cars sell in days; others take weeks. Don’t rush the process.
• Keep records of the sale, including the bill of sale and release of liability confirmation.

Selling a car in Washington State is entirely doable—even enjoyable—if you approach it the right way. Whether you’re upgrading, downsizing, or just ready for a change, following these steps will help you navigate the process with confidence. And remember, every car has a story.
