Connecticut: Private-Party Vehicle Title Transfer Requirements
The short answer
The seller signs the assignment and warranty of title on the back of the Connecticut certificate of title, filling in the buyer's name and address; no notary is required. Connecticut also requires a bill of sale (Form H-31 or your own with the listed details) to register, and the registration expires the moment ownership transfers, so the seller removes the plates and cancels the registration while the buyer applies for a new title and registration. The buyer must pay 6.35% sales or use tax (7.75% over $50,000) at registration and pass an emissions test if the vehicle is four or more model years old; a signed title alone does not let the buyer drive the car.

| Governing law, agency, and scope | Conn. Gen. Stat. §§ 14-16 and 14-179 (Uniform Motor Vehicle Certificate of Title and Antitheft Act) and Ch. 246-247; Connecticut Department of Motor Vehicles. Ordinary same-state private sale of a currently Connecticut-titled passenger vehicle; Connecticut does not title vehicles more than 20 model years old, and dealer, salvage, estate, and out-of-state rules differ. |
|---|---|
| Title assignment, owner signatures, and lien release | At delivery, the seller must 'execute an assignment and warranty of title to the transferee, showing the name and address of the transferee,' in the space on the certificate, and cause the certificate and assignment to be delivered to the buyer or the commissioner (§ 14-179(a)); the certificate carries a block-letter warning never to assign title without inserting the buyer's name and address. Any one joint owner named on the title and registration may transfer (§ 14-179(e)). A lienholder holding the title must deliver it for the transfer, and a paid-off lien must be released (§ 14-179(b); Connecticut issues only paper titles and has no electronic-title program). |
| Notarization, witness, or agent verification | No notary, witness, or agent verification is required. Section 14-179 requires an 'assignment and warranty of title' signed by the seller, but not a notarized or witnessed one, and the DMV's sell-and-transfer instructions add no acknowledgment step for the ordinary current-title transaction. |
| Bill of sale requirement and contents | A bill of sale is mandatory to register in Connecticut: 'A Bill of Sale (Form H-31) is required, along with proof of ownership, to process a new registration.' You may use Form H-31 or draft your own, which 'must contain' the purchaser's and seller's names and addresses, the vehicle description (make, model, year, color, VIN), the sales price, the date of sale, and the seller's signature (DMV). It supplements, and does not replace, the endorsed title. |
| Odometer, damage, and title-brand disclosures | Odometer disclosure is made on the title assignment or the bill of sale (Form H-31 has an odometer-reading field), under the federal odometer rule for vehicles generally under 20 years old. Because Connecticut does not title vehicles more than 20 model years old, the oldest cars are transferred with the last registration plus a Form Q-1 and H-31 rather than a title. No separate ordinary damage-disclosure form applies; salvage and rebuilt titles use a different process outside this scope. |
| Seller notice, plate handling, and liability | The registration 'expires upon transfer of ownership' (§ 14-16(a)); the DMV records the expiration when the seller cancels the registration or the buyer reregisters. The seller removes the plates and cancels the registration with the DMV (and keeps the receipt) — plates stay with the seller, not the car — and should keep insurance until the registration is cancelled, since until then the car remains subject to town property tax. A seller who has delivered possession and complied with the title-assignment steps 'is not liable as owner for any damages thereafter resulting from operation of the vehicle' (§ 14-179(d)). |
| Buyer deadline, forms, tax, and fees | Because the registration expires on transfer (§ 14-16(a)), the buyer must register and apply for a new title before driving; there is no separate in-state day-count deadline, but the car cannot be legally operated until registered. The buyer files an Application for Registration and Certificate of Title (Form H-13B) with the endorsed title, the H-31 bill of sale, the title fee, and required fees (§ 14-182). Connecticut sales or use tax on a private-party purchase is 6.35% of the price (7.75% for vehicles over $50,000), collected at registration (DMV/DRS). |
| Inspection, emissions, insurance, and operation | Connecticut has no separate state safety inspection for an ordinary private transfer, but a vehicle four or more model years old must pass an emissions test before it can be registered (exempt vehicles get a VIN verification instead). Liability insurance must be maintained on an active registration. A valid, current registration is required to operate on public roads, so the buyer cannot drive on the signed title alone — a temporary registration is available to move or test the car. |
| Penalties, rejection, and failed transfer | As between the parties, a transfer 'is not effective until the provisions of this section and section 14-182 have been complied with' (§ 14-179(d)) — an unsigned assignment, a missing buyer name/address, an unreleased lien, a missing bill of sale, or an unmet emissions requirement can stop the new registration and title. Operating the car without a current registration is itself a violation; the seller's cancellation of the registration limits the seller's exposure and property-tax billing but does not complete the buyer's title work. |

Requirements one by one
The assignment and warranty of title
Connecticut moves ownership through the certificate of title. Under § 14-179(a),
when an owner transfers a vehicle, "at the time of delivery of the vehicle" the
owner must "execute an assignment and warranty of title to the transferee,
showing the name and address of the transferee," in the space on the certificate,
and get the certificate and assignment to the buyer or the commissioner. The top
of every title carries a block-letter warning never to assign title without
filling in the buyer's name and address — leaving that blank is exactly what the
statute forbids. If the title lists joint owners, any one of them named on both
the title and the registration may sign the transfer (§ 14-179(e)).
Connecticut issues only paper titles and has no electronic-title program. A
lienholder holding the certificate must deliver it for the transfer, and a
paid-off loan has to be released before a clean title can pass (§ 14-179(b)).
No notarization
Connecticut does not notarize the title. Section 14-179 requires the seller's
signed "assignment and warranty of title," but not a notarized or witnessed one,
and the DMV's own sell-and-transfer steps add no acknowledgment for the ordinary
current-title sale. The seller simply signs the back of the title and completes
the bill of sale.
The bill of sale is required, not optional
This is where Connecticut differs from many states: a bill of sale is mandatory
to register. The DMV states that "a Bill of Sale (Form H-31) is required, along
with proof of ownership, to process a new registration." You can use Form H-31 or
draft your own; a self-drafted one "must contain" the buyer's and seller's names
and addresses, the vehicle description (make, model, year, color, VIN), the sales
price, the date, and the seller's signature. It supports the endorsed title; it
does not replace it.
Odometer and the 20-year title line
Odometer disclosure is made on the title assignment or on the H-31 bill of sale,
which has an odometer-reading field, under the federal odometer rule. Connecticut
does not title vehicles more than 20 model years old, so the oldest cars are
transferred with the last registration plus a supplemental assignment (Form Q-1)
and the H-31 rather than a certificate of title.
Registration expires the instant you sell
Section 14-16(a) is blunt: "A motor vehicle registration expires upon transfer of
ownership of the motor vehicle." The DMV records that expiration when the seller
cancels the registration or the buyer reregisters, whichever comes first. So the
seller removes the plates and cancels the registration with the DMV (keeping the
receipt) — plates belong to the owner, not the car — and keeps insurance in force
until the registration is cancelled, because until then the vehicle is still
billed for town property tax. A seller who has handed over the car and done the
title steps "is not liable as owner for any damages thereafter resulting from
operation of the vehicle" (§ 14-179(d)).
What the buyer files, pays, and tests
Because the registration is gone the moment ownership changes, the buyer must
register and apply for a new title before driving. There is no separate in-state
day-count deadline, but the car cannot be operated until it is registered. The
buyer brings the endorsed title, the H-31 bill of sale, and an Application for
Registration and Certificate of Title (Form H-13B), and pays the title fee, the
registration fees, and Connecticut sales or use tax — 6.35% of the price, or
7.75% for a vehicle over $50,000 (§ 14-182; DMV). If the vehicle is four or more
model years old, it must pass an emissions test before it can be registered.
What trips people up
- Assuming you can drive on a signed title. You cannot. The seller's
registration expired at the sale (§ 14-16(a)), and Connecticut requires a
valid, current registration to operate. Get a temporary registration to move
or emissions-test the car. - Skipping the bill of sale. It is required to register (DMV). No bill of
sale, no new registration. - Not cancelling the registration. If the seller never cancels, the town
keeps billing property tax on the car. Cancel the plates and keep the receipt. - Forgetting the emissions test. A vehicle four or more model years old has
to pass emissions before the buyer can register it.
Common questions
Does the Connecticut title need to be notarized?
No. The seller signs the assignment and warranty of title on the back of the
certificate; no notary or witness is required (§ 14-179).
Do I really need a bill of sale?
Yes. Connecticut requires a bill of sale — Form H-31 or your own with the listed
details — to process the new registration.
Who removes the license plates?
The seller. Plates stay with the owner. The seller removes them and cancels the
registration, and can transfer plates to another vehicle.
Can I drive the car home right after buying it?
Not on the old registration — it expired at the sale. Register the car (or get a
temporary registration) first; if it is four or more model years old, it also
needs to pass emissions.
