Selling a car in Missouri tends to look simple until the paperwork phase begins. Missouri places specific legal weight on how titles are completed, how mileage is disclosed, and—most importantly—how seller signatures are verified. Many private sales run into trouble not because of the vehicle, but because one overlooked formality makes the title unusable for registration.
This guide walks through how to sell a car in Missouri so the buyer can register without delay and the seller is fully released from responsibility.
What Missouri Sellers Should Check First
Missouri requires a valid certificate of title for most vehicle sales. Before advertising or meeting a buyer, confirm:
- Your name matches the title exactly
- Any lien listed on the title has been fully paid and released
- All owners listed on the title are available to sign
- The VIN on the vehicle matches the title
Missouri does require notarization of the seller’s signature on the title, which is one of the most important rules sellers must follow.
Title and Paperwork Rules in Missouri
Title Signing and Notarization
Missouri requires the seller’s signature on the title to be notarized.
Key points sellers must understand:
- The notary must witness the signature in person
- Signing first and notarizing later can invalidate the title
- All sellers listed on the title must appear before the notary
If notarization is missed or done incorrectly, the buyer may be unable to register the vehicle.
Odometer Disclosure
Odometer disclosure is required for vehicles that are not mileage-exempt due to age. Mileage must be entered accurately at the time of sale. Incorrect mileage entries can create registration delays and potential legal exposure.
Bill of Sale
A bill of sale is recommended in Missouri. While the notarized title transfers ownership, a bill of sale documents:
- Sale date
- Purchase price
- Buyer and seller information
This document can help resolve questions related to taxes or ownership timing.
Inspections and Emissions in Missouri
Missouri has safety inspection requirements for many vehicles being registered. While inspections are typically handled by the buyer after purchase, sellers should be aware:
- Vehicles that will not pass inspection are harder to sell privately
- Buyers often negotiate pricing based on inspection risk
- Some vehicles may be exempt based on age or usage
Missouri also has emissions testing requirements in certain counties, primarily in urban areas. Vehicles that cannot meet emissions standards often face reduced buyer interest.
License Plates, Registration, and Seller Responsibility
Missouri handles license plates differently than many states.
- License plates generally stay with the seller, not the vehicle
- Sellers should remove plates before releasing the car
- Buyers must register the vehicle and obtain their own plates
Leaving plates on a sold vehicle can result in tickets, tolls, or enforcement notices being sent to the seller.
Taxes and Fees
- Buyers are responsible for registration fees and applicable taxes
- Sellers are not responsible for buyer taxes after the sale
- Accurate sale dates help protect the seller
Keep copies of the notarized title and bill of sale for your records.
Special Situations Missouri Sellers Should Understand
- Selling with a lien: Vehicles with active liens cannot be sold unless the lien is paid off and released before transfer
- Two names on the title: Both owners must sign and both signatures must be notarized unless “OR” is specified
- Lost title: Replacing it before selling prevents delays and buyer hesitation
- Non-running vehicles: Missouri allows the sale of non-running vehicles, but inspection and emissions requirements can affect value
Getting Paid Safely
Private vehicle sales in Missouri still carry payment risks. Fake cashier’s checks, delayed transfers, and third-party pickup arrangements are common red flags. Never release the vehicle or notarized title until payment is fully verified and cleared.
For many sellers, payment security becomes the most stressful part of the process.
When Notarization and Inspections Slow Everything Down
In Missouri, coordinating a buyer, a notary, inspection concerns, and payment timing can quickly complicate a private sale. One missed notarization or inspection issue can send the entire transaction backward.
