A Connecticut bill of sale is a written record that you and the buyer (or seller) both sign to document the sale of a vehicle

Connecticut does not have a single official bill of sale form that the state requires you to use. Instead, you can write one yourself, use a template, or buy a pre-printed form from an office supply store. What matters is that the document records the key facts: who sold the car, who bought it, the vehicle identification number (VIN), the sale price, and the date of the sale. Both parties sign it, and each keeps a copy.

The bill of sale protects both you and the other person. For the seller, it proves you received payment and transferred ownership on a specific date. For the buyer, it shows they paid for the car and have a record of the transaction in case a dispute arises later. Connecticut does not require you to file the bill of sale with the state, but you will need it when you register the vehicle or transfer the title at the Connecticut Department of Motor Vehicles (DMV).

Key Takeaways

  • Connecticut law does not mandate a specific bill of sale form, so you can create one yourself, use a template, or buy a pre-printed form.
  • The bill of sale must include the seller's name and address, buyer's name and address, vehicle VIN, sale price, date of sale, and signatures from both parties.
  • Both the seller and buyer should keep a signed copy for their records, even though Connecticut does not require you to file it with the DMV.
  • The bill of sale is required when you register the vehicle or explore for a title transfer at the Connecticut DMV.

What information must go on a Connecticut bill of sale

At minimum, your bill of sale should include the seller's full name and address, the buyer's full name and address, and the date of the sale. Write out the date in full (for example, January 15, 2024) rather than using numbers alone, which can be misread.

Include the vehicle's complete VIN, which you can find on the driver's side of the dashboard, on the title document, or on the registration card. Also record the year, make, model, and color of the vehicle. Write the sale price in both numbers and words (for example, "$5,500 (five thousand five hundred dollars)") to prevent confusion or alteration. If the sale included a trade-in, note that separately from the cash price.

Both the seller and the buyer must sign and date the bill of sale. Some people also include the odometer reading at the time of sale, which can be useful if questions arise about the vehicle's condition or mileage history later. You can add a line stating the vehicle's condition (for example, "sold as-is") if that reflects your agreement.

Where to get a bill of sale form in Connecticut

The Connecticut DMV does not provide an official bill of sale form on its website, but you have several options. You can read a free template from the DMV's website or from other state government resources, then print and fill it out by hand. Many office supply stores sell pre-printed bill of sale pads that are already formatted with the necessary fields.

You can also write your own bill of sale on plain paper, as long as it includes all the required information and is signed by both parties. Some people use a bill of sale template from a reputable automotive website or legal document service. Whichever route you choose, make sure the final document is legible and that both parties have a clear, signed copy.

How to complete and sign the bill of sale

Fill in all the information while both the seller and buyer are present. Write clearly in pen so the document cannot be altered after signing. Do not leave blank lines or spaces where information could be added later. If you make a mistake, cross it out with a single line, write the correction above it, and have both parties initial the change.

Both the seller and buyer should sign the document in front of each other. Some people have the signatures notarized, which adds an extra layer of verification, though Connecticut does not require notarization for a bill of sale. If you choose to have it notarized, a notary public will verify the identities of both parties and witness the signatures. You can find notaries at banks, law offices, or title companies.

Once signed, make at least two copies: one for the seller and one for the buyer. Keep your copy in a safe place. The buyer will need the bill of sale when registering the vehicle or transferring the title at the Connecticut DMV.

When you need the bill of sale for the Connecticut DMV

The buyer will need to bring the signed bill of sale to the Connecticut DMV when registering the vehicle or explore for a title transfer. The DMV uses the bill of sale as proof of ownership transfer and to verify the sale price for tax purposes. Connecticut charges a sales tax on vehicle purchases, and the DMV calculates this tax based on the sale price listed on the bill of sale.

The seller should also keep a copy of the signed bill of sale for their records. If the buyer later claims the seller did not disclose a mechanical problem or if a dispute arises about the condition of the vehicle, the bill of sale serves as evidence of when and to whom the vehicle was sold. It does not settle disputes about the vehicle's condition, but it does establish the date and parties involved in the transaction.

What the bill of sale does and does not do

The bill of sale documents the sale itself—who bought, who sold, when, and for how much. It is not the same as the title, which is the legal document that proves ownership. The title is issued by the state and must be transferred separately at the DMV. The bill of sale supports that transfer but does not replace it.

The bill of sale also does not may provide the condition of the vehicle or protect the buyer from mechanical problems. If you sell a car "as-is," that phrase on the bill of sale means the buyer accepts the vehicle in its current condition. It does not shield you from liability if you knowingly hid a serious defect or if the vehicle has an outstanding lien (a loan against it). Always disclose known problems and make sure any loan on the vehicle is paid off before you sell it.

Common mistakes to avoid on a Connecticut bill of sale

Do not leave the sale price blank or vague. Write the exact amount both parties agreed to. If the buyer is assuming a loan on the vehicle, note that separately from any cash payment. Leaving the price unclear can cause problems when the buyer registers the vehicle, because the DMV needs the sale price to calculate sales tax.

Do not sign the bill of sale before filling in all the information. Once it is signed, changes become suspicious and may not be accepted by the DMV. Do not assume the buyer will handle the title transfer—confirm in writing who is responsible for submitting documents to the DMV and by what date.

Do not throw away your copy after the sale. Keep it for at least a few years in case questions arise about the transaction. If the buyer later has an accident or gets a ticket in the vehicle, a police officer or insurance company might contact you as the previous owner. Your signed bill of sale proves you no longer owned the vehicle at that time.

Frequently Asked Questions

Does Connecticut require a notarized bill of sale?

No, Connecticut does not require notarization. A bill of sale signed by both parties is sufficient. However, notarization adds verification that the signatures are genuine and can be useful if a dispute arises later. It costs a small fee but is optional.

What if I sell a car to a family member?

You still need a bill of sale, even for a family member. Write the actual sale price, even if it is lower than market value or if you are gifting the vehicle. The DMV uses the stated price to calculate sales tax, and misrepresenting the price can cause registration problems.

Can I use a bill of sale from another state?

You can use a bill of sale from another state as long as it includes all the required information and is signed by both parties. However, using a Connecticut template or creating your own ensures the document meets Connecticut standards and will be accepted without question at the DMV.

What happens if the buyer does not register the vehicle?

Once you have a signed bill of sale, you have transferred ownership. If the buyer does not register the vehicle, that is their responsibility. Keep your copy of the bill of sale to prove you sold it on a specific date. You may also want to notify the DMV in writing that you sold the vehicle, in case tickets or violations are later attributed to you.

Do I need a bill of sale if I trade in my car at a dealership?

No. Dealerships handle trade-ins through their own paperwork and do not require a separate bill of sale. The dealership's paperwork serves as the record of the transaction.
