Washington Bill of Sale Template

What a bill of sale does in Washington

A bill of sale records the transfer of ownership of personal property — a car, a boat, a piece of equipment, livestock, sometimes a firearm — from one private party to another. In Washington, the document acts as both a receipt for the buyer and a release of liability for the seller. Once signed, ownership has changed; the seller is no longer the legal owner and is no longer liable for what the buyer subsequently does with the item.

Washington's position is that Revised Code of Washington § 46.12.650 governs the form and effect of these transfers. The bill of sale itself does not transfer title to a vehicle on its own — that requires the Washington DMV to record the change of ownership using the TD-420-001.

What to include

• date
• seller name
• buyer name
• item description
• price

For a vehicle, also include: vin, odometer, year, make, model.

How Washington differs

Washington state uses TD-420-001 as the vehicle bill of sale; no notarization is required for private sales. For comparison, most US states do not require notarization, although having a notary or witness adds evidentiary weight if a dispute later arises.

Title transfer & registration in Washington

A bill of sale documents the deal, but for a vehicle it is only one step in changing the registered owner. In Washington, the general process runs in the same order: the seller signs over the certificate of title, both parties complete and sign the bill of sale (and TD-420-001, where Washington provides an official form), and then the buyer submits the transfer and registers the vehicle.

The buyer takes the assigned title and bill of sale to your local Washington DMV, applies for a new title in their own name, registers the vehicle, and pays the applicable titling and registration fees plus any tax due. Most states set a statutory window — often around a month — within which the buyer must complete the transfer, so file promptly to avoid late penalties. Confirm the current Washington fees, deadlines, and form versions on the official DMV page before you go.

Notarization & witnesses

Washington does not require the bill of sale to be notarized for a private vehicle sale. You can still choose to have it notarized at a bank, UPS Store, or law office — it is never wrong, and a notary's seal adds evidentiary weight if the transaction is ever questioned.

Sales & use tax

In the US, the buyer — not the seller — normally pays state and local use tax when they title and register the vehicle, and it is typically calculated on the purchase price. That is exactly why the price written on the bill of sale matters: your local Washington DMV may use the stated figure (or a fair-market value) to assess what is owed. Record the real, agreed price honestly. Exact rates, exemptions, and any local add-ons vary, so confirm them on the official Washington DMV page before registering.

Keep a copy & dispute evidence

Both the buyer and the seller should keep a signed copy of the bill of sale — ideally each retaining an original, or a clear scan or photograph of the fully signed document. For the seller it proves the date ownership and liability passed; for the buyer it proves what was paid and on what terms. Store it together with any handover photographs and a note of the odometer reading at sale. If a dispute arises later, this contemporaneous paperwork is the most persuasive evidence either party can bring to Washington's civil or small claims court.
