Bill of Sale vs. Title: What’s the Difference?
A bill of sale records the transaction between a buyer and seller. A title is the government’s proof of who legally owns the item. They do different jobs, and a complete vehicle sale usually needs both. Here is exactly how they differ and when you need each.
Side-by-side comparison
| Bill of Sale | Title (Certificate of Title) | |
|---|---|---|
| Who creates it | The buyer and seller | The state DMV / motor vehicle agency |
| What it proves | A transaction happened (price, date, parties, item) | Who legally owns the item |
| Primary purpose | Record of the sale + price for tax | Legal proof of ownership |
| Needed to register? | Supporting document (primary for untitled items) | Usually required for titled vehicles |
| Transfers ownership? | For untitled property, yes; for titled, it supports the transfer | Yes — signing it over transfers legal ownership |
| Who keeps it | Both buyer and seller keep a copy | The buyer (re-issued in their name by the DMV) |
Why a vehicle sale usually needs both
When you sell a titled vehicle, two things have to happen. First, legal ownership transfers when you sign the back of the title over to the buyer and the buyer records it with the DMV. Second, the transaction needs a record — the sale price (which the state uses to assess use tax), the date, the odometer reading, the VIN, and both parties’ details. That record is the bill of sale. The title handles the legal transfer; the bill of sale documents the deal and protects both sides.
When the bill of sale is the ownership document
Not everything gets a title. Many states do not title small utility trailers below a weight threshold, and some do not title certain ATVs, mopeds, golf carts, or farm equipment. For those items there is no certificate of title to sign over — the signed bill of sale, together with the state registration, is what establishes ownership. That is why a thorough bill of sale matters most exactly where no title exists.
Can you register with only a bill of sale?
For untitled items, yes. For a normally-titled vehicle with a missing title, usually not on the bill of sale alone — you would get a duplicate title from the seller, use a state affidavit of ownership, or apply for a bonded title. In each of those routes the bill of sale is important supporting evidence, but for titled vehicles it rarely replaces the title outright.
Frequently asked questions
- Is a bill of sale the same as a title?
- No. A bill of sale is a private document between the buyer and seller that records the transaction — who sold what to whom, for how much, and on what date. A title (Certificate of Title) is a government-issued document that proves who legally owns a titled item such as a car, truck, or larger boat. The bill of sale documents the sale; the title is the official proof of ownership.
- What is the difference between a bill of sale and a title?
- Four differences matter most: (1) Who issues it — a bill of sale is created by the buyer and seller, while a title is issued by the state DMV or equivalent agency. (2) What it proves — a bill of sale proves a transaction happened; a title proves legal ownership. (3) When it’s used — the signed title transfers legal ownership at the DMV, while the bill of sale supports the sale and records the price for tax purposes. (4) Whether it’s required — most states require the title to register a titled vehicle; the bill of sale is supporting documentation (and for untitled items, it becomes the primary ownership record).
- Do I need both a bill of sale and a title to sell a car?
- In most states, yes. To sell a titled vehicle you sign the title over to the buyer (this legally transfers ownership) and provide a bill of sale that records the price, date, VIN, and both parties. The buyer takes the signed title to the DMV to register the vehicle and pays tax based on the price shown on the bill of sale. The title does the legal transfer; the bill of sale is the transaction record both sides keep.
- Can you register a vehicle with only a bill of sale and no title?
- Sometimes — it depends on the state and the item. For items that are not titled at all (small utility trailers below a weight threshold, some ATVs and mopeds, golf carts, etc.), a signed bill of sale plus the registration application is the accepted way to establish ownership. For a normally-titled vehicle with a missing title, you usually cannot register on the bill of sale alone: you would ask the seller for a duplicate title, use a state affidavit of ownership, or apply for a bonded title. A bill of sale is strong supporting evidence in each of those paths, but for titled vehicles it rarely replaces the title outright.
- Which document do I keep — the bill of sale or the title?
- The buyer keeps the title (after registering it in their name, the DMV issues a new title to the new owner). Both the buyer and the seller should keep a copy of the bill of sale. For the seller, the bill of sale is proof of when ownership transferred — important for releasing liability, canceling insurance, and showing you no longer own the vehicle if it later incurs tickets or tolls.
- Does a bill of sale transfer ownership?
- For untitled property, yes — the bill of sale is the ownership document. For titled property like a car or a larger boat, the bill of sale evidences the agreement to transfer, but legal ownership formally passes when the title is signed over and the buyer records it with the state. That is why a complete sale of a titled vehicle uses both: the assigned title plus a bill of sale.
