Bill of Sale vs Title — What's the Difference?
A bill of sale records the sale; a title proves and transfers ownership. Here's how they differ, why you usually need both, and which one the DMV cares about.
People often use “bill of sale” and “title” interchangeably, but they’re completely different documents that do different jobs. Getting them straight is the key to a smooth vehicle sale.
The title: proof and transfer of ownership
A certificate of title is an official document issued by your state’s motor vehicle agency. It names the legal owner of a vehicle and, on the back, has an assignment section the seller signs to transfer ownership to a buyer. The title is the instrument that actually moves ownership from one person to another.
When you sell a car, signing over the title is the legal heart of the transaction. The buyer then takes that signed title to the DMV to register the vehicle in their name and get a new title issued.
The bill of sale: the record of the deal
A bill of sale is a private document — not issued by the state — that records the details of the sale: who sold the vehicle, who bought it, the price, the date, the odometer reading, and any terms like “as-is.” It proves a transaction happened and on what terms.
The bill of sale doesn’t transfer ownership of a titled vehicle by itself. Instead, it supports the title transfer and serves purposes the title doesn’t:
- Documents the price so the DMV calculates sales tax correctly.
- Records the odometer and condition.
- Establishes the date responsibility shifted to the buyer.
Side-by-side
| Title | Bill of Sale | |
|---|---|---|
| Issued by | The state (DMV) | The buyer and seller |
| Main job | Proves and transfers ownership | Records the sale’s details |
| Required to register a car? | Yes | Often (for tax / proof) |
| Proves the price? | No | Yes |
| Proves the mileage? | Sometimes | Yes |
Why you usually need both
For a vehicle, the two documents work together:
- The signed title is what the buyer submits to legally become the owner.
- The bill of sale documents the price for tax, records the odometer, and protects both parties if a dispute arises.
A few states even build the bill of sale into the title process — for example, New York asks for the bill of sale (MV-912) when titling, and several states use a combined form. See how your state handles it on our state requirement pages, and read the full vehicle ownership transfer guide.
When a bill of sale stands alone
For untitled property — furniture, electronics, equipment, most general goods — there is no title, so the bill of sale is the ownership record. And for very old, title-exempt vehicles, some states let you register with a bill of sale plus other proof. But for any modern titled vehicle, plan on having both.

Frequently asked questions
What is the difference between a bill of sale and a title?
A title is the state-issued certificate that proves who owns a vehicle and is used to transfer ownership. A bill of sale is a private document that records the details of the sale — the parties, price, date, and terms. The title transfers ownership; the bill of sale documents the transaction.
Can a bill of sale replace a title?
Generally no. For a titled vehicle, you can't register it with only a bill of sale — you need the signed title. A bill of sale alone is usually only enough for older, title-exempt vehicles or special bonded-title situations.
Do I need both a title and a bill of sale?
For a vehicle sale, usually yes. The buyer needs the signed-over title to register the car, and many states also want a bill of sale to confirm the purchase price for sales tax. Keeping both protects buyer and seller.
