How to check a U.S. boat for liens

1. Documented or state-titled?

Your search starts with knowing which system holds the boat’s records:

• USCG-documented vessels have a federal Certificate of Documentation issued by the National Vessel Documentation Center (NVDC). Mortgages on these vessels are recorded with NVDC and appear on a federal Abstract of Title.
• State-titled vessels have a state-issued title (like a car title). Mortgages and security interests are recorded at the state level — either on the title itself or via UCC-1 filings.

Ask the seller (or the broker) for the official number (documented) or the state title number, the HIN (Hull Identification Number — 12 characters, usually on the transom), and the registration number painted on the hull. With those in hand you can run the searches.

2. Abstract of Title from the USCG NVDC

For a documented vessel, the canonical lien check is an Abstract of Title from NVDC. It lists every recorded instrument against the vessel: bills of sale, preferred ship mortgages, claims of lien, satisfactions, and assignments.

You can order an abstract three ways:

• Directly from NVDC by mail using form CG-1332 (Request for Abstract of Title). Cheap (a few dollars per page), slow (typically 1–3 weeks).
• Online through an authorized vendor or a marine documentation service. Faster (often 24–72 hours), a bit more expensive ($75–$200).
• Through your marine documentation agent (the same firm that will handle the post-sale documentation transfer). Often bundled into closing services.

Order the abstract as early in your acceptance period as possible — definitely before you waive your title contingency.

3. Reading the abstract

The abstract reads chronologically. What you’re looking for:

• Unsatisfied mortgages. Each recorded preferred ship mortgage should be followed by a recorded satisfaction of mortgage (or a discharge) when the loan was paid off. Mortgages without matching satisfactions are still attached to the vessel.
• Claims of lien— anyone can file one against a documented vessel. They’re less common than mortgages but more dangerous because they often reflect a contested debt that’s never been formally resolved.
• The current owner of record. The seller named on your purchase agreement must match the last bill of sale on the abstract, end-to-end with no gaps.
• Endorsement. Confirm the documentation is current — an expired COD is fixable but slows your closing.

If anything looks wrong, get your closing agent or a maritime attorney on it immediately. Don’t close on a hope that “the seller will get the satisfaction filed soon.” The satisfaction has to be in hand at closing, recorded with NVDC, and reflected on a clean abstract.

4. State title and UCC searches

For state-titled vessels (under 5 net tons, or owners who chose state title over federal documentation), the lien check is at the state level:

1. Order a copy of the title record from the state DMV or titling office. Recorded liens appear on the title.
2. UCC-1 searchby the seller’s legal name in the state(s) where the seller resides, where the seller’s business is registered (if owned by an entity), and where the boat is moored. Most states offer online UCC search; some charge a small fee per result.
3. HIN search: a few states allow lien lookup by HIN, which catches liens that the seller’s name search misses.

UCC-1 filings catch dealer financing, equipment liens, and inventory financing. They expire after five years if not continued, so look at the date — old expired filings are noise, not a real lien.

5. Mechanic’s, marina, and fuel liens

These are the silent ones. Federal maritime law recognizes liens for “necessaries” — fuel, repairs, towing, dockage, supplies — that attach to the vessel automatically. They often don’t appear in any registry. Defenses:

• Seller’s warranty in the bill of sale that the vessel is free of all liens, encumbrances, and claims — explicitly including maritime liens for necessaries. The warranty should survive closing.
• Request receiptsfor recent yard work, dockage, and major repairs. Unpaid invoices in the boat’s history are a flag.
• Call the marina where the boat is currently moored. A phone call to the dock office often catches an unpaid slip bill that nobody mentioned.
• Title insurance (see below) covers what diligence misses.

6. Tax and IRS liens

Federal tax liens against an individual seller can attach to property including vessels. State sales/use tax liens are also possible if the prior owner failed to pay. Mitigations:

• UCC-style searches often turn up IRS Notices of Federal Tax Lien filed against the seller.
• State sales/use tax: confirm the seller can show evidence of tax paid at the prior purchase (or registration as exempt), so the state can’t come after you for the prior period.

7. Gaps in the chain of title

On older boats, the abstract sometimes shows a transfer that looks incomplete — a bill of sale with a missing intermediate owner, a documentation that was deleted and never re-issued, an entity owner that was dissolved without a proper transfer. These gaps are fixable but take time:

• A missing bill of sale can sometimes be reconstructed with affidavits from prior owners.
• A dissolved corporate owner requires the prior corporate officer to sign in a representative capacity, or court intervention if the entity is unreachable.
• A deleted documentation can be re-documented if eligibility is preserved and the prior deletion paperwork is in order.

If your abstract has gaps, factor four to eight extra weeks into your closing timeline and get a marine documentation agent or maritime attorney involved immediately.

8. Title insurance for vessels

A handful of carriers offer marine title insurance — coverage against lien claims the abstract didn’t reveal. Premiums are typically a few hundred to a few thousand dollars depending on vessel value. It’s most worth it on:

• Older boats with long ownership chains.
• Boats with complex documentation histories (deletions, re-documentations, foreign-flagged periods).
• High-value purchases where a hidden lien could be financially catastrophic.
• Boats bought from sellers in financial distress.

Where this fits in your timeline

The lien check should run in parallel with the survey, not after it. Order the abstract the day after your offer is accepted. By the time the surveyor finishes the report, you should have the abstract in hand and your title contingency either cleared or actively being worked. Close only on a clean record, with all satisfactions filed and confirmed.
