Does a bill of sale have to be notarized? In most cases, no. A bill of sale is a private contract, and once both parties sign it and exchange something of value, it is legally binding whether or not a notary was involved. The main exception is titled property: roughly half a dozen states require a notarized bill of sale before a motor vehicle title agency will process the transfer, and a handful of others impose the same rule on boats or trailers. Outside those situations, notarization is optional, though sometimes strongly advisable.
When Notarization Is Actually Required
For everyday items like furniture, electronics, tools, or lawn equipment, a signed receipt is enough. No provision of the Uniform Commercial Code, which governs the sale of goods in every state, makes notarization a condition of a valid sale.
The rule changes for high-value assets that carry a government-issued title. About six states require a notarized bill of sale before the title office will process a vehicle ownership transfer. Several additional states apply the same requirement to boats, trailers, or other titled property. Submitting paperwork without the notary’s seal in one of those states means the application gets rejected, which delays plates and legal registration.
Even where the state does not require it, other parties in the transaction sometimes do. Banks and credit unions financing a vehicle purchase often ask for notarized sale documents before releasing a lien. Insurance companies reviewing a claim tied to a recently bought vehicle may also want to see a notarized record of the sale. If any of those parties are involved, ask before you sign.
Why Notarize When It’s Optional
A notarized bill of sale carries more legal weight than one without a seal. Under Federal Rule of Evidence 902, a document accompanied by a notary’s certificate of acknowledgment is “self-authenticating,” meaning it can be admitted as evidence in court without separate proof that the signatures are genuine.1Legal Information Institute (LII) / Cornell Law School. Federal Rules of Evidence Rule 902 – Evidence That Is Self-Authenticating An unnotarized bill of sale, by contrast, could require witness testimony or handwriting analysis to establish who signed it.
That difference matters most when a deal goes bad. If the buyer later claims the seller lied about the price, or the seller argues the buyer never paid, a notarized document is much harder to attack. The notary’s seal confirms that both parties appeared in person, presented identification, and signed willingly, and those facts are difficult to dispute after the fact.
What the Bill of Sale Itself Needs
Whether you notarize or not, a complete bill of sale protects both sides. At a minimum, include:
- Full legal names and current residential addresses of the buyer and seller.
- A specific description of the property. For vehicles, that means year, make, model, body type, and the 17-character Vehicle Identification Number. For boats, include the Hull Identification Number.
- The exact sale price in dollars, even if it is zero. State tax agencies use this figure to calculate sales or use tax.
- The date of sale, which fixes when risk and responsibility shift to the buyer.
- Signatures from both parties. If you plan to notarize, leave the signature lines blank until you are in front of the notary.
For any item sold without a warranty, include a clear “as-is” statement. That language establishes that the buyer accepts the property in its current condition and the seller makes no guarantees about quality or function.
One separate federal requirement applies whenever a motor vehicle changes hands: the seller must give the buyer a written odometer disclosure certifying that the reading is accurate, has exceeded the odometer’s mechanical limit, or is unreliable. A false statement carries civil and criminal penalties. Vehicles that are 20 or more model years old are exempt.2Office of the Law Revision Counsel. 49 US Code 32705 – Disclosure Requirements on Transfer of Motor Vehicles3eCFR. 49 CFR Part 580 – Odometer Disclosure Requirements
How the Notarization Works
The process itself is short. Both the buyer and seller bring the unsigned bill of sale and a valid government-issued photo ID, such as a driver’s license or passport, to the notary. The notary checks the IDs, confirms the names match those on the document, and watches both parties sign. After witnessing the signatures, the notary applies an official seal or stamp and adds their own signature and commission expiration date. Keep the original and make copies as needed for the title office, lender, or insurer.
What It Costs
Most states cap the fee a notary can charge per signature, typically between $5 and $15, though a few states allow more. Remote online sessions carry higher caps in many states, sometimes $25 or $30 per signature. If you hire a mobile notary to travel to you, expect a separate travel fee. Some states tie that fee to the IRS mileage rate or a set per-mile amount; others let the notary set a reasonable charge. Ask for the total before the appointment.
Fixing Mistakes After the Fact
If you spot an error on a notarized bill of sale, such as a misspelled name, a wrong date, or an incorrect VIN, the fix depends on the state. Some states prohibit any changes after notarization and require both parties to meet the notary again for a fresh signing. Where corrections are allowed, the standard method is to draw a single line through the error, write the correct information nearby, and have the notary initial and date the change. Do not use correction fluid or tape on a notarized document. It can void the notarization and raise fraud concerns.
Notarizing Remotely
You do not always have to appear in person. As of early 2025, at least 45 states and the District of Columbia have permanent laws allowing remote online notarization, where the signer and notary connect through a live audio-video session. The notary verifies your identity through credential analysis of your government-issued ID and knowledge-based authentication questions, then watches you sign electronically. The audio and video must stay continuous and clear, and the connection must be encrypted. The notary applies a digital seal that carries the same legal effect as a physical stamp.
Interstate recognition is the catch. A bill of sale notarized remotely by a notary commissioned in one state may not be automatically accepted by a title agency in another. The SECURE Notarization Act, which would require states to accept remote notarizations from other jurisdictions, has been introduced in multiple sessions of Congress but as of 2026 has not become law. Before relying on an out-of-state remote notarization for a vehicle or boat transfer, call your local title office.
After You Sign
Signing the bill of sale is not the last step for either party. Most states require the seller to notify the motor vehicle agency that the vehicle has been sold. This release-of-liability notice separates the seller from parking tickets, toll violations, or accidents that occur after the sale date. Without it, the vehicle stays linked to the seller in state records and automated enforcement systems will keep mailing citations to the seller’s address.
Deadlines for filing the notice generally run from five to 30 days after the sale, and many states allow online submission. You’ll need the buyer’s name and address, the license plate number, and the VIN. Filing the notice does not transfer the title; the buyer still has to apply for that separately.
For the buyer, the priority is completing the title transfer and registration within the state’s window, typically 10 to 30 days after purchase. Missing that deadline can trigger late fees that stack up monthly, and some states add penalties for driving an unregistered vehicle.
