A cross-border due-diligence case study by Sian Gissing, LL.B (Hons), Sian Gissing Strategic Legal Consultancy.
A yacht should bring freedom. Uncertainty in the paperwork can bring quite the opposite.
You have found the vessel. The proposed price is €320,000. Your plans are taking shape. But before you commit, what evidence supports the ownership history, the VAT position and the vessel’s right to circulate in the waters where you intend to keep it?
In a recent instruction, a prospective buyer asked SGSLC to examine those questions. According to the transaction information provided to me, the broker sought an 8% commission: €25,600 calculated against the proposed price.
The commission and the due-diligence work served different purposes. One concerned arranging the transaction. My instruction concerned the documentary basis on which my client would decide whether to proceed.
The buyer ultimately withdrew. The work nevertheless produced important evidence and a clearer account of what had, and had not been established.
The Starting Point: Assurances Without A Complete Transaction File
The broker maintained that the transaction was ready to proceed and explained to my client a history involving England, Malta, Austria and Greece. However, the limited documents initially made available did not substantiate every part of that account.
At the point of instruction, the file relied on an incomplete chain of bills of sale and a sales invoice. Those documents required investigation; they did not, on their own, resolve the ownership trail or establish the VAT and customs position to my satisfaction.
Key supporting evidence had not been supplied:
- A complete, reconciled chain of title connecting the relevant transfers.
- Sufficient evidence substantiating the claimed VAT-paid position.
- Mooring, storage or guardianage records documenting the yacht’s whereabouts during summer berthing and winterisation.
- Evidence of TEPAI payments, commonly handled through Greece’s eTEPAI system, for the relevant periods where applicable.
- Evidence establishing the yacht’s current Union status in Greece following the end of the Brexit transition period.
Missing documents were not, by themselves, proof of unpaid tax, defective ownership or unlawful use. They were unresolved questions that needed answers before my client could make an informed commitment.
My response was to investigate beyond the verbal account: examine the root title and subsequent ownership trail, obtain official registry evidence, submit the available VAT material to HMRC and pursue clarification of the separate customs and location questions. The findings and their limits are set out below.
Issue One: A Vessel’s Identity Must Survive Changes of Name and Flag
The history described to me involved an original UK title trail, later Maltese registration, subsequent Austrian ownership or registration arrangements, changes of name or flag, and the yacht’s presence in Greece.
These are different kinds of event. A sale is not a voyage. A change of flag does not establish where a vessel was physically located. An owner’s nationality does not establish the yacht’s customs status.
My approach: examine the ownership documents and registry history together, using the hull identification number and other identifying particulars to connect the records. A familiar vessel name alone is insufficient.
The builder’s certificate and earliest bill of sale along with the builder certificate and original transcript register certificate are important starting points in a title investigation. Their precise contents must be checked; a UK ownership or registration history does not mean a yacht was built in Britain.
Document One: The Maltese Transcript of Register
The transcript supplied for this case records: 2nd Owner from UK to EU waters.
| Recorded event | Date or description |
|---|---|
| Construction | France, 2012 |
| Previous registry | United Kingdom |
| Provisional Maltese registration | 28 October 2014–25 February 2015 |
| Subsequent Maltese registration | 26 February 2015–16 June 2021 |
| Closure of the Maltese registry entry | 16 June 2021, at the owners’ request |
| Transcript issued | 14 September 2026 |
It also contains a statement concerning registered ownership and freedom from registered encumbrances as at the stated date.
Why it matters: it provides an official reference point for part of the vessel’s registration history. It allows dates and particulars to be tested against the wider transaction file.
What it does not establish: the vessel’s physical location on a particular date, the complete later ownership history, the absence of every possible maritime lien, or its current EU customs status. Its historical register was closed in 2021; this is not proof of a current Maltese registration.
The response to an incomplete history is to investigate the next link, not to assume the gap is harmless.
Issue Two: “VAT paid” Needed To Become An Evidenced Conclusion
The buyer wanted confidence in the VAT position. A description in an advert or a seller’s explanation can identify a question; it cannot answer that question by itself. There was no evidence of VAT being paid or the vessel declared to the Greek Customs office as an imported good. I used my skills to secure confirmation VAT was paid upon the original Bill of Sale.
My approach: review the available evidence and submit it to HMRC’s pleasurecraft function for consideration of the historic UK VAT position.
Document Two: HMRC’s Written VAT Confirmation
Although the filename contains an earlier date, the letter itself is dated 21 September 2026. It confirms that, on the documents sighted after I had submitted a carefully prepared bundle of evidence, the HMRC was satisfied that UK VAT at the prevailing rate had been accounted for on the original purchase and had not been reclaimed. HMRC also states that it is satisfied the vessel is UK VAT paid.
Why it matters: an important aspect of the investigation moved beyond assertion to written clarification from the relevant UK authority.
The limit matters just as much: this is confirmation of the UK VAT position described in the letter. It is not a certificate of current EU Union status, a guarantee against every future tax liability, or an endorsement of SGSLC.
An original VAT invoice can itself be important evidence. The purpose of this enquiry was to clarify the evidence available in this particular transaction.
Issue Three: UK VAT History and EU Customs Status Required Separate Attention
Once historic UK VAT had been addressed, a further question remained: what established the vessel’s customs position in Greece and the wider EU?
The key date: 31 December 2020 at 23:00 UTC
Where the yacht physically was at the end of the Brexit transition period is a crucial question. The relevant instant was 23:00 UTC / 11 p.m. UK time on 31 December 2020, equivalent to 01:00 in Greece on 1 January 2021. This is the historical status cutoff, not a deadline for submitting documents now.
Articles 126 and 127 of the UK–EU Withdrawal Agreement establish the transition period and the general application of EU law during it. Section 39 of the European Union (Withdrawal Agreement) Act 2020 defines UK “IP completion day” by reference to that 11 p.m. instant.
The customs assessment sits within the Union Customs Code, Regulation (EU) No 952/2013, including Articles 153–155 on Union status, its loss and relevant exceptions. A yacht already holding Union status and located within the EU27 customs territory at the cutoff could retain that status; physical presence alone did not turn a non-Union yacht into Union goods. Later departures, re-entry and customs procedures must also be examined.
Flag, registry, ownership nationality and historic VAT payment do not, individually, prove the yacht’s physical location at the cutoff. HMRC’s pleasurecraft guidance likewise distinguishes VAT evidence and evidence of location.
Proving location with contemporaneous records
My investigation therefore needed records identifying this vessel and covering the relevant date, rather than a general account of where it had travelled:
- Dated marina and mooring invoices, berth records and confirmation of actual occupation.
- Guardianage or caretaking records confirming attendance at the identified location.
- Winterisation, haul-out, launch and ashore-storage records and invoices spanning the cutoff.
- Contemporaneous logbook entries, checked against independent port, marina or service records where available.
- Relevant port clearances, customs records and supporting dated maintenance or insurance-survey records.
A reserved berth or paid invoice does not necessarily prove actual presence. Records should be reconciled against the yacht’s identity, dates and movements. TEPAI receipts may support the wider chronology but do not themselves certify Union status.
The task is to establish a coherent, evidenced location history at the critical instant and assess the subsequent customs history. The competent authority determines the evidence it requires; mooring receipts and logbook entries are supporting records, not automatic substitutes for any prescribed customs proof. Special rules may apply to movements that began before the cutoff and ended afterwards, including Article 47 of the Withdrawal Agreement. Northern Ireland also requires separate consideration.
My approach: treat the Greek/EU customs position as a separate enquiry and distinguish it from the UK VAT confirmation. Seek the relevant movement, location and customs records and clarification from the competent authorities, as appropriate to the vessel’s circumstances.
The supplied documents do not include a final Greek customs determination confirming Union status. This case study therefore does not claim that such confirmation was obtained.
Similarly, an account that the yacht physically left the UK one month before the end of the transition period requires dated movement or location evidence. The Maltese registration dates cannot establish that journey. Later Austrian registration, renaming and reflagging also require their own supporting records.
Progress means distinguishing a resolved question from one that remains open.
Document Three: Explaining The Chain of Title
This graphic explains how a vessel’s identity, original title documents, sales records and authority correspondence can be considered together.
Its first three stages use an illustrative vessel and hull number. They are not reproductions of this yacht’s actual builder’s certificate, bill of sale or invoice. The fourth stage reproduces a redacted extract of a real authority letter.
Why it matters: a clear visual explanation helps a client understand why one document cannot answer every question. Registry evidence, ownership evidence and VAT evidence each have a different role.
The graphic’s reference to checking Union status in Greece should be read as a separate enquiry to pursue, not proof that a favourable determination was issued. Likewise, a sales invoice should be assessed on its merits; it is not inherently unreliable because it is an invoice.
The Outcome: A Clearer Decision, Not A Promised Completion
My client ultimately decided not to proceed with the purchase. I had advised against signing the broker’s agreement on the terms presented. It required the full purchase price of €320,000 to be transferred before the outstanding documents requested for disclosure had been produced. The proposed receiving account was not clearly identified, and no satisfactory evidence of regulated client-account or independent stakeholder safeguards had been provided.
For me, this was the decisive red flag. My client should not have been expected to commit substantial funds, alongside the proposed commission, while material questions remained unresolved concerning the chain of ownership, missing documents and the yacht’s VAT and customs position.
The decision to withdraw was a considered response to those unresolved risks. It was not a finding of fraud, nor a conclusion that the yacht could never be sold following the production of a complete and satisfactory documentary file.
Although my investigation obtained written clarification of the historic UK VAT position, established important Maltese registry dates, and identified the limits of what those documents could prove.
The lesson is that a transaction can become better understood even where the final decision is to walk away.
My Proposed Standard For Future Transactions
I favour a written Pre-Purchase Agreement, or appropriately drafted Conditional Sale Agreement, establishing an initial seven-day due-diligence period. This is my proposed framework for future transactions.
The agreed work should cover identity and authority checks, the ownership trail, relevant registry and encumbrance enquiries, VAT and customs evidence, and a current independent marine survey. Earlier survey reports provide background; they do not establish present condition.
Seven days must not become pressure to accept incomplete evidence. Survey availability and authority responses may require a written extension. Withdrawal rights, deposit refunds, expenses, stakeholder arrangements and any continuing obligations must be expressly agreed under the applicable law.
A Better Prepared Sale Benefits Everyone
For a private owner, assembling the evidence before listing can bring questions forward. For a broker, a coherent transaction file can support a better-qualified pipeline and reduce avoidable delays. For a buyer, it creates a more informed basis on which to commit savings, retirement funds and future plans.
Independent due diligence belongs in the purchase budget. Its purpose is not to promise a problem-free yacht; it is to identify the questions that deserve answers before the money moves.
A considered purchase. A properly prepared sale. A clearer path to completion.
