Car Bill of Sale Notarization: Which States Require It (and Which Don't)

In most states, a car bill of sale does not need to be notarized. It is normally valid once the buyer and seller sign it. The bigger issue is the vehicle title: a few states require the seller’s title assignment to be notarized before the buyer can register the car.

If you are not sure, use this rule of thumb: the bill of sale records the deal, while the title transfers ownership. Some DMVs care much more about the title signature than the bill of sale signature.

Quick answer by situation

Situation	Notary usually needed?	What to do

Sale in Louisiana, Ohio, Pennsylvania, North Carolina, or Kentucky	Often yes	Do not sign the title until you are with a notary or authorized title agent.

States where notarization commonly matters

For a private car or vehicle sale, notarization commonly matters in these states:

• Louisiana
• Ohio
• Pennsylvania
• North Carolina
• Kentucky

In these states, the requirement is often tied to the title assignment, not just a separate bill of sale. That means the seller may need to sign the title in front of a notary or authorized title agent.

Louisiana

Louisiana’s Office of Motor Vehicles says a used vehicle file can include the current certificate of title assigned before a notary by the seller to the purchaser. If neither the bill of sale, invoice, nor title is notarized in certain out-of-state cases, OMV may require extra notarized proof.

Use: Louisiana vehicle bill of sale and confirm on the Louisiana OMV title and registration page.

Ohio

Ohio title assignments commonly require a notarized seller signature. The practical rule is simple: do not sign the Ohio title until the seller is with a notary, clerk, or authorized title office that can witness the signature.

Use: Ohio vehicle bill of sale and confirm on the Ohio BMV title page.

Pennsylvania

PennDOT says the seller’s signature is required to be notarized or verified on the Pennsylvania title. In practice, private vehicle transfers are usually completed through an authorized PennDOT agent, messenger, dealer, or notary.

Use: Pennsylvania vehicle bill of sale and confirm on the PennDOT buying or selling a vehicle page.

North Carolina

North Carolina title paperwork commonly uses notarized signatures on vehicle title forms and related title applications. If you are selling or buying a vehicle in North Carolina, plan to complete the title paperwork with a notary or license plate agency.

Use: North Carolina vehicle bill of sale and confirm on the NCDMV vehicle titles page.

Kentucky

Kentucky’s vehicle titling instructions state that signed-over Kentucky title signatures must be notarized. If the title or registration comes from a state that uses a bill of sale instead of a title, Kentucky may still require notarized signatures.

Use: Kentucky vehicle bill of sale and confirm on the Kentucky vehicle titling page.

States with tax-related notarization

Some states do not require every car bill of sale to be notarized, but they may require a notarized form when the vehicle is sold below market value. Examples include Maryland, Virginia, West Virginia, and Oklahoma.

The reason is tax verification. The DMV may want proof that the low sale price is real before calculating sales or use tax from that amount.

Maryland

Maryland commonly uses a notarized bill of sale when the vehicle is sold for less than book value and the buyer wants tax calculated from the actual sale price. See the Maryland vehicle bill of sale page before signing.

Virginia

Virginia may require extra price-certification paperwork for certain low-price or gift transfers. See the Virginia vehicle bill of sale page and confirm tax forms with the DMV.

West Virginia

West Virginia may require notarized price documentation when a vehicle is sold significantly below book value. See the West Virginia vehicle bill of sale page for the current state-specific checklist.

Oklahoma

Oklahoma uses state-specific title and excise-tax rules where notarization can matter depending on the document and transaction. See the Oklahoma vehicle bill of sale page and confirm with Service Oklahoma before signing.

How to get a car bill of sale or title notarized

If your state requires notarization, bring the unsigned document, a valid government ID for each signer, and any title or DMV form that needs the notary block completed.

Common options:

Notary option	Best for	Notes
Bank or credit union	Existing customers	Many branches offer low-cost or free notary service.
UPS, FedEx, or shipping store	Fast local appointment	Call ahead because not every location has a notary on duty.
DMV, tag, title, or messenger office	Title transfer states	Often the safest option when title paperwork must be notarized or verified.
Online notary	Remote convenience	Only use it if your state and the specific DMV form accept remote online notarization.
Local notary public	Flexible signing location	Confirm ID requirements and fees before meeting.

Do not sign before you are in front of the notary. The notary verifies identity and witnesses the signature; they usually cannot notarize a signature that already happened.

What to include even if no notary is required

A strong car bill of sale should include:

• Buyer and seller full legal names
• Buyer and seller addresses
• Vehicle year, make, model, and color
• The 17-character VIN
• Exact odometer reading
• Sale price or gift terms
• Sale date
• As-is language, if the car is sold without a warranty
• Buyer and seller signatures

You can create this with the free vehicle bill of sale template or open the bill of sale generator and choose your state.

Should you notarize anyway?

You can notarize a car bill of sale even when it is not required, but it is not always worth the extra step. A notary verifies identity and signature, not whether the car is in good condition or whether the sale terms are fair.

If the sale is high value, disputed, between strangers, or happening in a state with confusing title rules, notarization can add a useful layer of proof. For an ordinary private car sale in a state that does not require it, a complete signed bill of sale plus a properly assigned title is usually enough.

The safest signing order

1. Check your state’s DMV rule before meeting the buyer.
2. Fill out the bill of sale with the VIN, odometer, price, and sale date.
3. If your state requires notarization, wait to sign the title until you are with the notary or title agent.
4. Make at least two signed copies: one for the buyer and one for the seller.
5. The buyer should register the car quickly, and the seller should file any required notice of sale or release of liability.
