Quick answer: separate Connecticut title and registration steps

Connecticut titles vessels model year 2017 and newer unless an exemption applies; documented vessels are not eligible for a Connecticut title. A seller should match the HIN, provide the title or prior ownership record, complete a bill of sale, disclose liens and give the buyer the documents needed for a DMV registration appointment.

Confirm the current process with the Connecticut DMV boat registration route and DEEP boating information. This page focuses on the seller handoff; the general boat seller checklist covers common tasks.

Connecticut seller checklist

  1. Confirm the vessel model year and whether a Connecticut title or exemption applies.
  2. Match the HIN on the hull to the title, registration and bill of sale.
  3. Complete the seller assignment on the title when the vessel is titleable.
  4. Prepare a bill of sale with buyer and seller names, date, price, HIN and vessel description.
  5. Disclose and resolve liens, keeping the lender release with the transaction file.
  6. Give the buyer the title or ownership record, current registration and any AIS or tax records that apply.
  7. Keep copies and tell the buyer that initial registration is handled by DMV appointment before launching.

Connecticut registration fees vary by vessel length, hull material and owner type. Refer the buyer to the DMV fee chart instead of promising a fixed amount in the sale agreement.

Use the boat bill of sale template for recordkeeping, then follow DMV instructions for the appointment packet and DEEP requirements.

Documented vessel, missing title or out-of-state sale

Documented vessels are not eligible for a Connecticut title and may require a different registration or decal path. If a title is missing, the HIN does not match or the vessel comes from another state, ask DMV or DEEP which ownership proof and inspection documents are required before closing.

For the buyer's post-sale filing sequence, see how to register a boat after a private sale. For trailer paperwork, use boat trailer registration.

Boat and trailer handoff

List the boat and trailer as separate assets. Connecticut DMV handles the vessel registration and title record, while the trailer follows motor-vehicle rules. Confirm both filing routes before transporting the combination.

Connecticut AIS decals, taxes, registration fees and appointment requirements can change. Direct the buyer to current DMV and DEEP instructions.
