Home > Guides > Faxing a car bill of sale
Yes, dealers and insurance companies routinely accept a faxed bill of sale as proof that a car changed hands. The exception is the DMV or title office: registering the vehicle in the buyer's name typically requires the original signed document or a certified copy, not a fax. Plan on faxing for speed and following up with the original for the title.
| Recipient | Faxed copy accepted? |
|---|---|
| Your insurance company | Usually yes: they need proof of the sale to adjust or cancel the policy, and fax is their standard intake |
| The buyer's insurance company | Usually yes: binds coverage to the vehicle immediately |
| A dealer (trade-in or payoff) | Usually yes: fax gets the paperwork started while originals travel |
| A lender financing the purchase | Often yes for the file, with the original required for their records |
| DMV / title office / ServiceOntario | Typically no: registration needs the original or a certified copy |
Registration is a legal transfer of ownership, and title offices want to inspect the actual signatures, not a degraded fax copy. Signatures blur in transmission, and a title clerk checking for forgery needs the real ink. Some jurisdictions also require the bill of sale to be notarized or accompanied by an odometer disclosure statement, which comes with its own original-signature rules. In Ontario, the vehicle permit (ownership) transfer happens through ServiceOntario with the signed permit and a safety standards certificate: a faxed copy won't do, but the buyer can bring it in person or a dealer can register on their behalf.
Whether you fax it or hand it over, the document needs the same fields: full names and addresses of buyer and seller, the vehicle year, make, model, and VIN, the odometer reading, the sale price, the date of sale, and both signatures. The VIN is the critical identifier: it is seventeen characters long, and a single misread digit in a faxed copy can attach the sale to the wrong vehicle. Copy it directly from the dashboard plate or the driver's door sticker, not from memory, and double-check it before faxing.
Fax the signed original, not a copy of a copy: every generation loses detail, and VIN digits and signatures are exactly what degrades. Darken the copy if the signatures are light. If the bill of sale is on a dealer form with small print, test the transmission to yourself first (most fax setups can send to a second number you control) or ask the recipient to confirm legibility on arrival. Keep the confirmation page with your copy of the bill of sale: in a private sale, it proves when the other party received the paperwork, which matters if a dispute arises about the sale date.
In a private sale, faxing the bill of sale is mostly about the seller's protection. Fax a copy to your insurer the same day to end your coverage and liability for the vehicle: some policies cover a sold car until you notify them, and a gap can leave you exposed if the buyer drives away uninsured. Give the buyer the original for registration. Both parties should keep a signed copy with the odometer reading recorded: if tickets or tolls arrive later addressed to the seller, the bill of sale with its date is the proof the car had changed hands.
