To transfer a car title in Missouri, you need to complete the assignment of title section on the back of the current title, get a notarized signature from the seller, and then the buyer must take the title, along with proof of and identification, to a Missouri Department of Revenue (DOR) License Office to pay the sales tax and complete the transfer. The most common mistake is an improperly notarized signature, which will cause significant delays.
The process differs slightly depending on whether there is a lien on the vehicle and if it's a sale between private parties or from a dealer. The key document is the Certificate of Ownership (the title) itself. The seller must accurately complete the "Assignment of Title" section on the back, including the odometer reading, sale price, and date of sale. Their signature must be notarized; signatures from a notary public in other states are not accepted. The buyer should keep the title and a bill of sale for their records.
As the buyer, your responsibility is to visit a Missouri DOR office within 30 days of the purchase to title the vehicle in your name and pay the required state and local sales tax. You will need:
| Fee Type | Typical Cost | Notes |
|---|---|---|
| Title Fee | $8.50 - $11.00 | Varies by office processing fee. |
| Sales Tax | 4.225% of sale price | State rate. Local rates add an average of 3.5%. |
| Local Sales Tax | Varies by county/city | Can range from 0% to over 5%. |
| Processing Fee | $6.00 | Standard DOR fee. |
| Lien Recording Fee | $5.00 | Only if you are financing the vehicle. |
If the title is lost, the seller must apply for a duplicate before the sale can proceed. After a successful transfer at the DOR, you will receive new license plates or transfer existing ones, completing the process.

Just went through this last month. The biggest hassle is the notary. Don't sign the title until you're in front of one! The buyer and I met at our bank, signed everything with the notary there, and it was smooth. The buyer took the notarized title to the DMV. I made sure to keep a copy of the bill of sale for my records just in case. It’s a pretty straightforward process if you have all your paperwork lined up.

As a buyer, your focus is on the DOR visit. Secure the notarized title and a bill of sale from the seller. Call your agent to bind coverage effective the purchase date before you drive away. At the License Office, you'll present these documents, complete an application, and pay the sales tax based on the price you paid. The state fee for a new title is minimal, but the tax is the main cost. You'll leave with temporary plates if needed.

Be cautious of title jumping, where someone flips a car without titling it in their name to avoid taxes. Always verify the seller's name on the title matches their ID. If there's a lien listed, ensure the lender provides a lien release document. For older vehicles, be aware of Missouri's minimum requirements for a rebuilt title if the car has been salvaged. These steps protect you from a vehicle with a questionable history.

The cornerstone is the notarization. Missouri law is strict: the seller's signature on the title assignment is invalid without it from a Missouri notary. The 30-day deadline for the buyer to title the vehicle is also critical; penalties apply for late registration. The bill of sale, while not always strictly required, is vital proof of the transaction details for both parties. It resolves disputes over the agreed-upon price and sale date, which directly impacts the sales tax you'll owe.
