Yacht Purchase Due Diligence

The buyer-side guide to verifying an existing yacht before you commit: ownership, title, registry, class, tax, records, inventory and closing.

Lund Group Yacht DeskCharter & Brokerage Desk13 min readReviewed 6 October 2026

Due diligence is how a buyer turns a seller's statements into verified facts. This guide explains what is checked, who checks it and how findings shape the decision, without replacing your maritime lawyer, surveyor or tax adviser.

Short answer

Due diligence verifies that the seller can deliver the yacht you think you are buying: with clear authority, without undisclosed charges, with the regulatory and tax status claimed, with records that support its condition, and with everything listed in the inventory. Your lawyer, surveyor and tax adviser each verify part of it; Lund Group coordinates.

Six distinctions buyers often miss

Registered owner ≠ beneficial owner
The registry shows a company; the individual behind it is verified privately through KYC.
Asset sale ≠ share sale
Buying the yacht is different from buying the company that owns it and its history.
Flag ≠ VAT status
Flag determines applicable rules, not whether VAT was paid.
Class ≠ survey
In class does not mean in good condition.
Clean survey ≠ clean title
Condition and legal title are verified separately.
Deposit ≠ due diligence
Paying a deposit secures the timetable; it does not verify anything.

What yacht purchase due diligence is

Due diligence is the structured verification a buyer carries out before committing to acquire an existing yacht: who owns it, whether they can sell it, what is registered against it, what its regulatory and tax position is, what condition its records describe, and exactly what the sale includes.

It is wider than a survey. A survey examines the physical yacht; due diligence examines the yacht as a legal, regulatory, tax, technical and operational asset. A clean survey does not mean clean title, and clean title does not mean a sound hull.

When it starts and who leads it

Light screening begins before an offer: identity of the yacht, the seller entity, broad registry and class status, and any obvious red flags. Detailed verification usually runs after the purchase agreement is signed and the deposit lodged, in parallel with survey and sea trial.

The buyer's maritime lawyer normally leads title, registry, encumbrance and contract work. The surveyor leads physical condition. Tax advisers lead VAT and customs. The broker coordinates the timetable, document requests and communication between parties.

  • Broker ≠ lawyer: a broker coordinates, a lawyer advises on title and contract.
  • Broker ≠ surveyor: a broker does not certify condition.
  • Lund Group coordinates specialists; it does not give legal, tax or survey opinions.

Pre-offer screening

Before an offer, a buyer can reasonably ask for the yacht's official identifiers, flag, class society, seller entity type, a summary of refit history and the general VAT position as stated by the seller. These are seller statements until verified.

  • Confirm the yacht's name, hull/official number and IMO number (where applicable) are consistent across documents.
  • Ask whether the yacht is privately or commercially registered.
  • Ask whether any charters, crew contracts or management agreements will remain in place.
  • Note anything the seller declines to disclose.

NDA, data room and document index

Sellers often share documents through a data room after a non-disclosure agreement. A good document index lists each document, its date and its issuer, and separates current certificates from historical records.

Access should be restricted to named advisers. Registry extracts, corporate documents, tax evidence and proof of funds are private and should never be forwarded informally.

Registered owner and beneficial owner

The registered owner is the person or company shown on the yacht's registry. The beneficial owner is the individual who ultimately owns or controls that company. Most large yachts are held by a company, so the two are usually different.

Buyers verify the registered owner through the registry, and the beneficial owner through KYC carried out by lawyers, banks or escrow agents. Beneficial ownership information remains private and is not published.

Seller entity and authority to sell

Due diligence confirms that the seller company exists and is in good standing, that its directors have approved the sale, and that the person signing is properly authorised. Where a power of attorney is used, its scope, validity and execution are reviewed.

  • Certificate of incorporation and good standing (or local equivalent).
  • Register of directors.
  • Board resolution approving the sale.
  • Specimen signatures or identification of signatories.
  • Power of attorney, if any, with its formalities checked by counsel.

Asset sale or share sale

In an asset sale the buyer acquires the yacht itself and the seller company remains with the seller. In a share sale the buyer acquires the company that owns the yacht, including its history, contracts and any liabilities.

A share sale is not a shortcut. It usually needs company due diligence as well as yacht due diligence, covering accounts, contracts, employees, tax filings and claims. Whether either structure suits a buyer is a question for legal and tax advisers.

Title, mortgages and encumbrances

A title search on the registry shows the registered owner and any registered mortgages. A registered mortgage does not automatically stop a sale, but it must be discharged, or otherwise dealt with as agreed, at or before closing.

The usual approach is for the mortgagee to confirm the redemption amount and to provide a discharge at closing, paid from the sale proceeds through the agreed account.

Maritime liens, arrests and claims

A maritime lien is a claim that may attach to the yacht itself, for example for crew wages, salvage or certain damage, and in some jurisdictions it may survive a change of ownership without appearing on the registry. A registered mortgage and a maritime lien are different things.

An arrest is a court order detaining a yacht as security for a claim. Buyers ask about pending litigation, unpaid crew, yard and supplier claims, and rely on contractual warranties and indemnities, because not every claim can be found by searching a registry.

  • No search can certify that a yacht is free of every possible claim.
  • Seller warranties, disclosure schedules and indemnities allocate that risk.
  • Lund Group does not certify clean title.

Registry and flag

The registry extract should be recent, ideally obtained close to signing and again before closing. Buyers check whether the yacht will remain on its current registry or be deleted and re-registered, and what deletion certificate and timing the seller must provide.

Flag is not the same as VAT status, class, or the purchase vehicle. Flag tells you which state's rules apply to registration, safety and crewing.

Private or commercial status

A commercially registered yacht is typically operated for charter under a relevant code and may carry specific certificates, manning and survey obligations. Commercial registration does not mean the yacht can charter everywhere, and it does not prove VAT has been paid.

A buyer who wants private use should understand what changing status involves, and whether booked charters must be honoured.

Class status, conditions and the survey cycle

A class status report shows whether the yacht is in class, the dates of upcoming surveys, and any conditions of class or recommendations. It should be dated close to the transaction.

A condition of class or recommendation is not the same as a survey defect, and a yacht in class is not proof of good condition. Upcoming class renewal surveys and dry-docking can represent significant cost.

Statutory certificates and special systems

Depending on size and use, review may cover load line, safety, pollution prevention, tonnage, minimum safe manning, radio and other statutory certificates, with their expiry dates and any outstanding items. Port state control history may also be relevant.

Guest capacity, helideck certification and other special-system approvals are verified from the documents, never inferred from listings, photographs or size.

VAT status and what 'VAT paid' means

'VAT paid' is a seller statement. On its own it does not say in which jurisdiction, on what value, when, or whether later events such as modifications, commercial use or exportation have changed the position.

Evidence typically includes original invoices, customs or import documents and proof of payment. Flag, commercial registration and the location of the yacht are not evidence of VAT status. A qualified tax adviser should review the evidence; this guide does not advise on structuring or avoidance.

Go deeperYacht VAT guide

Customs, importation and temporary admission

Some yachts operate under temporary admission or similar regimes. A buyer needs to understand how a sale, the buyer's residence and the place of delivery may affect that status. Delivery location and sale location are not proof of tax status and should be agreed with tax advice.

Maintenance records and PMS

A planned maintenance system (PMS) records scheduled and completed work. Buyers review it alongside invoices, logs and the surveyor's findings. A service record shows work was recorded, not that the system is in good condition today.

Engine and generator hours, overhaul history, manufacturer service reports and oil analysis help the surveyor and engine specialists form a view.

Refit claims and warranties

Refit claims are verified against yard invoices, specifications, class records and completion documents. Cosmetic work is not technical work, and a major refit is not a rebuild. Stated refit spend is not proof of the value added.

Warranties from yards and manufacturers are checked for duration, transferability and open claims.

Go deeperYacht refit guide

Drawings, software and digital access

As-built drawings, manuals and system documentation should transfer with the yacht. Navigation, AV, IT and monitoring systems may rely on licences, subscriptions or accounts held by the seller or a manager. Passwords, admin access and cybersecurity handover are planned before closing.

Inventory and exclusions

The inventory list should state what is included and the list of exclusions should state what is not. Tenders, toys, a support yacht, a helicopter, a submersible, artwork and personal effects are often treated separately, and some may be owned by other entities.

Charter inventory such as linen, tableware and water-sports equipment should also be listed.

Crew, captain and management

Crew employment does not automatically transfer with the yacht. Contracts, employer entity, accrued wages, leave, repatriation obligations and potential crew claims are reviewed, and the buyer decides whom to retain.

The captain's knowledge of the yacht is valuable during handover. Management agreements, and ownership of PMS data and records held by a manager, are reviewed for termination and transfer.

Booked charters and the central agency

If the yacht has charters booked, the contract must say whether they will be honoured, who receives charter fees and deposits, and how the central agency arrangement ends or continues. A buyer who wants private use should resolve this before signing.

Berth and insurance

A berth is usually held under a licence or lease, not as real estate ownership. Transferability, remaining term, fees and landlord consent are checked.

Insurance does not normally transfer automatically. Buyers arrange cover from closing and ask about existing claims, loss and incident history and how damage was repaired.

Contract, conditions and seller representations

The purchase agreement sets out conditions, the acceptance process, seller representations and disclosure schedules. Matters found in due diligence are often addressed through specific representations, conditions or indemnities drafted by counsel.

Documents required at delivery

The closing document list is transaction-specific and is prepared by the lawyers. It commonly includes:

  • Bill of sale.
  • Protocol of delivery and acceptance.
  • Deletion certificate or arrangements for continued registration.
  • Certificate of non-encumbrance or equivalent registry evidence.
  • Mortgage discharge, where applicable.
  • Corporate authority documents for the seller.
  • Original certificates, manuals and records, and the agreed delivery timing.

Deposit and due diligence

A deposit secures the transaction timetable; it is not security against bad title, and paying it is not due diligence. Deposit terms, account holder and release conditions are reviewed by counsel.

Go deeperDeposit & escrow guide

Three parallel workstreams

Legal and title review, technical survey and sea trial, and tax review usually run in parallel. Each produces findings that feed the buyer's decision.

Go deeperSea trial guide

Handling material issues

Not every finding matters equally. An issue is material when it affects title, safety, regulatory status, tax exposure or value in a significant way.

An issue does not automatically lead to a price cut. Options include cure by the seller before closing, accepted risk, a specific indemnity, an escrow or hold-back, renegotiation, or walking away within the contract terms.

Financing, valuation and acquisition economics

A lender's due diligence protects the lender and does not replace the buyer's own review. Asking price is not value after diligence; findings on refit needs, class cycle, crewing, management, insurance, registration and VAT shape the revised acquisition economics.

Go deeperYacht financing guide

Sanctions, KYC and AML

Banks, escrow agents, lawyers and registries carry out know-your-client checks on both sides, including proof of funds, source of funds, buyer structure and seller KYC. Sanctions screening is carried out by qualified parties against the facts, never by assumptions about nationality.

Lund Group does not provide guidance on avoiding KYC, AML or sanctions controls, and declines transactions that cannot pass them.

Off-market, direct and brokered sales

Off-market, direct-owner and friend-to-friend sales need the same verification as public sales, often more, because fewer documents may be prepared in advance. Brokered public sales usually provide a document pack, but listing data remains a seller statement until verified.

Information on Lund Group listings comes from sellers, central agents and public sources. It is not a substitute for verification and may change.

Closing readiness

A transaction is ready to close when the lawyers confirm the agreed documents, discharges and funds are in place, acceptance has been given, and delivery arrangements are agreed. Timetables follow the contract; there are no universal deadlines.

Questions

What is yacht purchase due diligence?
The verification of a yacht's ownership, title, registry, class, certificates, tax position, records, inventory and operational arrangements before a buyer commits to purchase.
When does due diligence start?
Light screening starts before an offer; detailed review usually runs after the purchase agreement is signed, alongside survey and sea trial.
Who leads due diligence?
Typically the buyer's maritime lawyer for legal matters, the surveyor for condition and a tax adviser for VAT, coordinated by the broker.
What is the difference between due diligence and a survey?
A survey examines physical condition. Due diligence also covers legal, regulatory, tax and operational matters.
How do I verify who owns the yacht?
Through a current registry extract showing the registered owner, plus corporate documents for the seller entity reviewed by counsel.
How do I know the seller has authority to sell?
Through corporate existence documents, a board resolution, confirmation of signatories and review of any power of attorney.
What is the difference between registered and beneficial owner?
The registered owner appears on the registry, usually a company. The beneficial owner is the individual who ultimately owns or controls it.
How do I check the yacht's registry?
Your lawyer obtains a recent registry extract from the flag registry and checks it against the yacht's identifiers.
How do I check for a mortgage?
Registered mortgages normally appear on the registry extract. The mortgagee confirms the redemption amount and discharge arrangements.
What is a maritime lien?
A claim that may attach to the yacht itself, such as unpaid crew wages or salvage, and that may survive a sale without appearing on the registry in some jurisdictions.
What is an arrest?
A court order detaining a yacht as security for a claim.
How do I know the yacht can be delivered free of encumbrances?
Through registry evidence, mortgage discharges, seller warranties and indemnities. No search can guarantee the absence of every claim.
What does class status tell me?
Whether the yacht is in class, upcoming surveys and any conditions or recommendations. It does not prove good condition.
What does flag status tell me?
Which state's registration and safety rules apply. It does not show VAT status or class.
What certificates should be reviewed?
Statutory certificates appropriate to the yacht's size and use, class certificates, and any special approvals such as helideck or guest capacity.
What does private vs commercial status change?
Certification, manning, survey regime and permitted use. Commercial status does not prove VAT paid or allow charter everywhere.
How do I verify VAT status?
A tax adviser reviews original invoices, customs documents and proof of payment against the yacht's history.
What does 'VAT paid' actually mean?
It is a seller statement that needs evidence: where, when, on what value, and whether later events changed the position.
How do I review customs and importation history?
Through import documents and customs records reviewed by a tax or customs adviser.
What if the yacht has been under temporary admission?
Ask a tax adviser how the sale, your residence and the delivery location may affect that status before agreeing terms.
How do I review maintenance records?
Review the PMS, invoices and logs alongside the survey. Recorded service does not prove present condition.
How do I verify refit claims?
Against yard invoices, specifications, class records and completion documents.
How do I review engine and generator hours?
Compare hour readings with service records and overhaul history, and have engine specialists assess them during survey.
How do I check warranties?
Confirm their duration, whether they transfer to a new owner, and whether there are open claims.
What items are included in the sale?
Those on the agreed inventory list attached to the contract.
What is excluded?
Items on the list of exclusions, often personal effects, art or separately owned assets.
What happens to tenders and toys?
They are included only if listed. Some may be owned by other entities and need separate transfer.
What happens to crew?
Crew employment does not transfer automatically; the buyer decides whom to retain and arrangements are agreed.
What happens to booked charters?
The contract states whether they are honoured and how fees and deposits are treated.
What happens to the berth and insurance?
Berth rights depend on the licence or lease terms. Insurance normally does not transfer; arrange your own cover from closing.
Is a deposit protection against bad title?
No. A deposit secures the timetable. Title protection comes from verification, warranties and the closing mechanics.
Does Lund Group give legal or tax advice?
No. Lund Group coordinates the transaction and works with your lawyers, surveyors and tax advisers.
