To legally transfer ownership of a federally documented vessel, the seller(s) must complete and sign a USCG Bill of Sale (Form CG-1340) in the physical presence of a licensed Notary Public. The form must convey 100% of the listed ownership interest matching the existing Certificate of Documentation.
The notarized Form CG-1340 must then be submitted to the NVDC alongside an Application for Exchange/Transfer (Form CG-1258), proof of U.S. citizenship, filing fees, and formal satisfaction documents for any active Preferred Marine Mortgages.

What is required to legally transfer ownership of a federally documented vessel?
Buying a federally documented vessel requires specific steps, clear paperwork, and complete accuracy to ensure the legal title transfers smoothly. When acquiring a documented vessel, the primary document used to transfer ownership from the seller to the buyer is an official U.S. Coast Guard (USCG) Bill of Sale (Form CG-1340).
Unlike a standard state-issued receipt or generic contract, this federal instrument must be properly executed, notarized, and submitted to the National Vessel Documentation Center (NVDC) alongside appropriate transfer forms to officially reflect the change in ownership. Sourcing official documentation through government portals or authorized online filing platforms allows boat buyers and sellers to submit required forms safely and avoid administrative delays.
Executing a USCG Bill of Sale and Verifying 100% Ownership Transfer
Executing a valid USCG Bill of Sale (Form CG-1340) requires meticulous accounting of all listed vessel owners and the exact percentage of ownership interest being conveyed. The NVDC requires strict adherence to specific standards when completing this instrument.
Essential Identification and Ownership Parameters
- Matching Vessel Identity: The exact official name of the vessel must match the current Certificate of Documentation.
- Official Coast Guard Number: The assigned 6- or 7-digit USCG official number must be accurately listed without missing digits.
- Hull Identification Number (HIN): The 12-character uninterrupted HIN must be verified against physical vessel markings.
- Exact Seller Match: The names of all selling parties must appear exactly as recorded on the existing federal title.
- Complete Buyer Designation: The legal names and mailing addresses of all incoming buyers must be clearly designated.
- Consideration Statement: The document must explicitly state the total consideration or purchase amount exchanged.
Ownership Interest Rule: Form CG-1340 requires that 100% of the ownership interest is fully accounted for during the transaction. If a vessel is owned by multiple individuals, partners, or corporate entities, every single interest holder must be accounted for on the form. Partial transfers where fractions of interest remain unassigned cause instant filing rejections. Buyers must specify how they intend to hold title—such as Joint Tenancy with Right of Survivorship or Tenancy in Common.
Technical Regulatory Matrix: Notarization Rules & Application Forms
Understanding federal compliance requirements under 46 CFR Part 67 ensures that forms pass NVDC examination without deficiency notices.
| Legal Instrument / Requirement | Form Identifier | Governing Regulation | Mandatory Execution Protocol |
|---|---|---|---|
| USCG Bill of Sale | Form CG-1340 | 46 CFR Part 67, Subpart P | Signed by ALL sellers & notarized in ink/digital |
| Exchange / Transfer Application | Form CG-1258 | 46 CFR Part 67, Subpart I | Completed by buyer(s); verifies U.S. citizenship |
| Encumbrance Search | Abstract of Title | 46 CFR Part 67, Subpart Q | Issued by NVDC; verifies active/satisfied mortgages |
| Lien Release Document | Satisfaction of Mortgage | 46 CFR Part 67, Subpart M | Executed by lender/mortgagee to clear encumbrance |
Mandatory Notary Public Acknowledgment & Error Restrictions
Federal standards under 46 CFR Part 67 require every seller to sign the USCG Bill of Sale in the presence of a licensed Notary Public.
Protocol Criteria for Valid Notarization
- Physical / Approved Presence: Signatures must be executed in the direct physical or legally approved presence of a Notary Public.
- Venue Designation: The notary acknowledgment block must explicitly state the state and county where the signing took place.
- Clear Stamp & Expiration: The notary seal or stamp must be clear, legible, and unexpired.
- Capacity Designation: Corporate officers signing on behalf of an entity must state their corporate capacity (e.g., President, Managing Member).
- Trustee / Agent Authority: Trustees or authorized agents must provide documentation of legal authority to sign.
Zero-Alteration Rule: The NVDC strictly prohibits uncertified alterations. If a mistake occurs on Form CG-1340, strike-throughs, white-out, or corrective fluid used after notarization invalidates the document. A completely fresh form must be executed and re-notarized.
Submitting Form CG-1340 Alongside Form CG-1258 & Abstract Checks
Obtaining the signed, notarized Bill of Sale from the seller is only part of the conveyance procedure. To complete the transfer of ownership at the federal level, the buyer must submit Form CG-1340 together with Form CG-1258.
Complete Application Checklist
- Conveyance & Application Pairing: Pair the executed Form CG-1340 with the completed Form CG-1258.
- Citizenship Verification: Verify that all buyer citizenship requirements are satisfied for federal documentation eligibility (US citizens, qualified US corporations/LLCs).
- Operational Endorsements: Select desired operational endorsements (Recreational, Coastwise, Fishery, Registry).
- Encumbrance Check: Request a USCG Abstract of Title to confirm the absence of active Preferred Marine Mortgages or maritime liens.
- Lien Satisfaction: Ensure any existing Preferred Marine Mortgages are accompanied by a formal Satisfaction of Mortgage executed by the lender.
- Operational Rules: Keep the current Certificate of Documentation aboard the vessel during operation until the updated certificate is issued.
