A bill of sale in Oregon is not required for every private vehicle transaction, but the DMV insists on one in several specific situations, and even when it is optional a signed document protects both buyer and seller. The official form is the Vehicle Bill of Sale (Form 735-501), and at a minimum it must show the VIN, a statement releasing the seller’s interest, the seller’s printed name and original signature, and the date of sale.
When the Oregon DMV Requires One
For most straightforward private sales, a properly signed-over title is enough on its own. The DMV asks for a bill of sale when the paper trail has a gap it cannot close from the title alone.
The most common trigger: the seller’s name is not on the title. If someone sells you a car they bought but never titled in their own name, the DMV needs a bill of sale from that person to link the last titled owner to you.1Oregon Driver & Motor Vehicle Services. Buying or Selling a Vehicle Beyond that, the DMV requires original bills of sale in these cases:
- Estate transfers where the title has no survivorship clause and the estate is being probated. The personal representative provides a bill of sale or release.
- Assembled, reconstructed, or replica vehicles. Bills of sale for all major parts used in the build must accompany the title application.
- Salvage titles. Original bills of sale from all previous owners are required.
- Out-of-state or missing titles. When the original was issued by another state, or the Oregon title is lost or destroyed, a bill of sale helps the DMV verify the transaction.
Each of these is spelled out in the DMV’s title application instructions.2Oregon Driver & Motor Vehicle Services. Titling and Registering Your Vehicle
What Has to Be on It
The DMV sets a firm minimum of five items: the vehicle identification number, a statement that the seller is releasing their interest in the vehicle, the seller’s printed name, the seller’s original signature, and the date of sale. A document missing any of the five will not be processed.1Oregon Driver & Motor Vehicle Services. Buying or Selling a Vehicle You can use Form 735-501 or draft your own document, as long as it covers the same ground.3Oregon Department of Transportation. Vehicle Bill of Sale Form 735-501
Include more than the bare minimum in practice. Recording the year, make, and model of the vehicle, the sale price, and the buyer’s full name and address makes the document far more useful if a disagreement surfaces later. The DMV’s form has fields for all of it. If the sale is “as-is,” write that on the document; it can protect the seller from warranty-related claims.
The signature has to be original. Photocopies are not accepted.3Oregon Department of Transportation. Vehicle Bill of Sale Form 735-501 Use ink on paper for anything you’re handing to the DMV.
Odometer Disclosure
Federal law requires an odometer disclosure on transfers of vehicles from model year 2011 and newer. A 2019 rule change extended the window from 10 years to 20 years from the model year.4Federal Register. Odometer Disclosure Requirements In 2026, that covers every vehicle from model year 2011 through 2026. The Oregon DMV follows this federal threshold.5Oregon Department of Transportation. Oregon DMV Handbook Chapter H
The disclosure is usually printed on the title itself. If the title has no space for it, or if a bill of sale is your primary transfer document, put the current mileage on the bill of sale along with both signatures. Understating the reading is a federal offense.
Does It Need to Be Notarized?
Not for the DMV. A bill of sale signed by both parties is sufficient for title processing.1Oregon Driver & Motor Vehicle Services. Buying or Selling a Vehicle
Law enforcement can be different. If you need to retrieve an impounded vehicle using a bill of sale rather than a title, some Oregon police departments require that bill of sale to be notarized and dated within the previous 30 days.6City of Portland Police Bureau. Towed Vehicles Buyers get caught out because the same unnotarized document the DMV accepted will not necessarily work at a tow yard. If there’s any chance you’ll have to prove ownership before the title is in your name, get the bill of sale notarized at signing. It usually costs under $15.
The Seller’s 10-Day Notice
Sellers have to notify the DMV of the sale within 10 days. You can do it online through DMV2U, and the notice must include the buyer’s name and address.1Oregon Driver & Motor Vehicle Services. Buying or Selling a Vehicle The 10-day deadline and the required information come from the administrative rule implementing ORS 803.112.7Oregon Secretary of State. OAR 735-020-0080 – Notice of Transfer of Interest in a Vehicle
Skipping this step is one of the costliest mistakes a seller can make. Under ORS 803.117, a seller who has both notified the DMV of the transfer and assigned the title cannot be held civilly or criminally liable under Oregon vehicle law for how the buyer later parks, abandons, or operates the car.8Oregon Public Law. Oregon Code 803.117 – Effect of Notice of Transfer on Civil and Criminal Liability Without that notice on file, parking tickets, towing fees, and even accident liability can circle back to you because the DMV’s records still show the vehicle in your name. Filing takes a couple of minutes online and costs nothing.
The Buyer’s 30-Day Title Deadline
Buyers have 30 days from the date of sale to submit a title application. Miss the window and you owe a late fee: $25 between 31 and 60 days after the transfer, $50 after 60 days.2Oregon Driver & Motor Vehicle Services. Titling and Registering Your Vehicle The DMV can waive the late fee if you show a good-faith effort to get the title or that the delay was outside your control.9Oregon State Legislature. Oregon Revised Statutes Chapter 803 – Section 803.105 Oregon does not charge sales or use tax on vehicle purchases, so title and registration are the main government costs.
Boats Use a Different Form
Boat transfers do not use the vehicle bill of sale. The Oregon State Marine Board has its own form, and you submit it with your application for boat title and registration. If the Oregon title has been lost, you file a separate lost-title application. The same 30-day deadline applies, and a $25 late fee kicks in if you don’t transfer within it.10Oregon State Marine Board. Boat Bill of Sale
Use One Even When It’s Optional
Writing a bill of sale takes five minutes and costs nothing. Without one, the buyer has no proof of what they paid, the seller has no proof they actually sold the vehicle, and neither party has documentation of the sale date that starts the 30-day title-transfer clock. A signed document with the VIN, sale price, both parties’ names, and the date resolves most disputes before they start. The DMV wants originals, so have both parties sign two copies, or the buyer should photocopy the document before submitting it.
