As a Washington-state business and legal template specialist with over twelve years drafting vehicle transfer documents for dealers, private sellers, and title companies, I’ve helped thousands of residents correctly complete a release of interest car Washington State transaction without delays or rejected paperwork. The single most important form in almost every private-party vehicle sale in Washington is the Vehicle/Vessel Release of Interest — officially known as Form TD-420-040.
In this comprehensive guide, I’ll give you my battle-tested process for using the Washington State vehicle release of interest form, explain exactly when it’s required, show you common mistakes that trigger DOL rejections, and — most importantly — provide a free, fillable, up-to-date 2025 version of TD-420-040 for instant download.

A release of interest Washington State is the legal act of a registered owner (or lienholder) giving up all rights to a vehicle or vessel. Once the Release of Interest (Form TD-420-040) is signed and dated, that person or entity can no longer be held liable for tickets, tolls, accidents, or taxes related to the vehicle after the release date.
According to the Washington Department of Licensing (DOL), “The seller must either report the sale within 5 days or complete a Release of Interest” (Source: dol.wa.gov/vehicleregistration/sellvehicle.html).
You need the release of interest WA form in these common scenarios:
If the seller accompanies the buyer to the licensing office and signs the title in front of an agent, a separate TD-420-040 is usually not required — but I still recommend completing one for liability protection.

I’ve seen hundreds of rejections because of tiny mistakes. Follow this exact order:
| Section | Required? | Common Mistake |
|---|---|---|
| VIN | Yes | Transposing numbers |
| All owner signatures | Yes | Only one spouse signs “and” title |
| Handwritten date | Yes | Typed or pre-filled date |
| Buyer name | Recommended | Leaving completely blank |
After signing the title and handing over the keys, many sellers think they’re done. They’re not. Until the buyer titles the vehicle, DOL records still show you as owner.
Real example from my files: Client sold a 2012 Subaru in Tacoma in June 2024. Buyer never titled it. In September, the car was impounded in Seattle with $1,800 in tickets. Because my client had filed the Release of Interest the day of sale, DOL removed the tickets from his record in 48 hours.
Steps every seller should take:
If your loan is not yet paid off, the lienholder (not you) must sign the Release of Interest section on the title itself or provide a separate lien release letter on their letterhead. Many banks now use the same TD-420-040 — just check the “Lienholder releasing interest” box.

| Report of Sale (online or Form TD-420-500) | Release of Interest (TD-420-040) | |
|---|---|---|
| Required within | 5 days of sale | No strict deadline but recommended immediately |
| Removes plates from your record | Yes | No — only ends ownership liability |
| Prevents tickets/tolls after sale | Partially | Yes — stronger protection |
| Cost | $13.25 online | Free |
I always recommend doing both for maximum protection.
Do I need to notarize the Release of Interest?
No, unless it is a lienholder release required by court order.
Can I email the form to DOL?
Yes — use the DOL online filing portal or email to titles@dol.wa.gov with clear scans.
What if the buyer lost the form?
You can complete and file a new one at any time. Date it the original sale date.
Does the form expire?
No, but the earlier you file, the better your liability protection.
Following these steps has saved my clients thousands in mistaken tickets, tolls, and even lawsuits over the years.
