Selling a car privately in Connecticut
In a Connecticut private sale you sign the back of the title over to the buyer and hand them a bill of sale; Connecticut publishes a standard form (H-31), and the buyer needs it to register. No notary is required. Very old vehicles (roughly 20 or more model years) can be title-exempt, in which case the bill of sale and prior registration do the work; confirm with DMV if that applies to you.
The step Connecticut sellers most often miss: cancel your registration with the DMV after the sale. Connecticut assesses local property tax on registered vehicles, so an uncanceled registration keeps tax accruing in your name, and you should keep insurance active until the registration is canceled. Plates belong to the seller; remove them and cancel or transfer them through DMV.
The checklist
- 1
Sign the title over and complete Form H-31 (Connecticut)
Complete the assignment on the back of the Connecticut title and give the buyer a bill of sale; DMV's Form H-31 is the standard.
- 2
Cancel your registration with CT DMV
Cancel promptly after the sale so property tax stops accruing in your name, and keep the cancellation receipt for your town assessor.
- 3
Remove your license plates
Connecticut plates stay with the seller. Remove them and cancel or transfer them; do not cancel insurance until the registration is canceled.
- 4
Verify your title status
Locate the physical title and confirm it is in your name with no undisclosed liens. If the title is lost, request a duplicate before listing.
- 5
Complete a bill of sale
Recommended for every private sale even where not required. Record buyer/seller names, VIN, price, date, and an as-is acknowledgement. Both parties keep a copy.
- 6
Complete the odometer disclosure
Federal rules require odometer disclosure for most vehicles under 20 model years old. Usually done on the title itself; some states use a separate form.
- 7
File a release of liability / notice of sale
If your state offers it, file promptly after the sale so you are not liable for tickets or incidents after the buyer drives away.
- 8
Handle plates per your state's rules
In most states the seller removes the plates; in some, plates stay with the vehicle. Confirm your state's rule before handing over the keys.
- 9
Pay off any lien before or at transfer
If a lien remains, coordinate payoff with the lender so the buyer can receive a clear title. Do not sign over a title with an unreleased lien.
- 10
Confirm payment before signing the title
Verify cash, or use a cashier's check verified with the issuing bank, or complete the transfer inside the buyer's bank. Never release the signed title before funds are confirmed.
- 11
Keep copies of everything
Photograph or copy the signed title (both sides), bill of sale, odometer disclosure, and the buyer's ID if they consent.
- 12
Check official state instructions
Requirements change. Confirm the current process on your state DMV / motor vehicle agency website before the sale.

Does a Connecticut car title need to be notarized?
No. Sign the assignment on the back of the title and give it to the buyer with a completed bill of sale (Form H-31).
Why does canceling my Connecticut registration matter so much?
Until you cancel, the vehicle stays on the local property tax rolls in your name and DMV expects continuous insurance on the active registration. Cancel the registration promptly after the sale, keep the plate receipt, and only then cancel insurance.
What goes in the Connecticut bill of sale?
Make, model, year, VIN, odometer reading, price, date, and both parties' names and signatures. Form H-31 covers it; the buyer presents it at registration.
Who pays sales tax in a Connecticut private sale?
The buyer, when they register: 6.35% of the price in most cases (a higher rate applies to vehicles over $50,000). Some family transfers are exempt.
