Cross-Jurisdictional UK Investigations

Why UK investigations increasingly cross borders

Money moves freely across borders. People and companies exploit jurisdictional complexity to conceal assets, evade tax, hide beneficial ownership, and escape accountability. The major financial scandals affecting UK actors over the past decade — offshore tax avoidance, beneficial ownership concealment, sanctions evasion — have all had cross-border dimensions that required journalists to work outside the UK to investigate them.

The UK is both a victim and a beneficiary of offshore complexity. The City of London and the UK financial system are major channels for international capital, including capital of questionable provenance. The British Overseas Territories and Crown Dependencies — including the British Virgin Islands, Jersey, and the Isle of Man — are among the world’s most significant offshore centres and are frequently used by UK actors. Investigating these connections requires UK journalists to work with partner organisations in other jurisdictions, access international company registries, and understand how UK regulators interact with their overseas counterparts.

The global investigative journalism networks — ICIJ, OCCRP, EIC.network, and Forbidden Stories — exist precisely because cross-border accountability requires cross-border journalism. UK journalists can both contribute to and benefit from these networks.

UK-linked offshore jurisdictions

When cross-jurisdictional research is essential

• 1A UK company's corporate structure leads you to an offshore subsidiary that cannot be researched through Companies House alone.
• 2A UK individual has assets, companies, or litigation in another jurisdiction that is central to the story.
• 3The story involves sanctions evasion — tracing assets moved through multiple jurisdictions to circumvent UK/EU sanctions.
• 4A source tells you money was moved offshore through a specific jurisdiction — you need to verify through that jurisdiction's registry.
• 5The investigation concerns a pattern of behaviour across multiple countries — requiring parallel reporting partners.
• 6You have a document from a jurisdiction you do not have expertise in — a partner organisation in that country can verify and contextualise it.

Red flags in cross-border corporate structures

• ⚠Nominee directors — individuals who appear on company registers as directors but are actually proxies for the real beneficial owner.
• ⚠Circular ownership structures — Company A owns Company B which owns Company A — designed to obscure who ultimately controls assets.
• ⚠Rapid jurisdictional changes — a company structure that has moved through several offshore jurisdictions in a short period.
• ⚠Registered agent addresses shared by hundreds or thousands of companies — a formation agent address rather than a genuine place of business.
• ⚠Beneficial ownership information withheld in a jurisdiction that provides limited public access — seek alternative verification routes.
• ⚠UK-linked structures involving sanctioned individuals or politically exposed persons (PEPs) from high-risk jurisdictions.

Cross-jurisdictional investigation checklist

• I have mapped the full corporate structure from the UK entity outwards, identifying all subsidiaries, parent companies, and associated entities in each jurisdiction.
• I have searched OpenCorporates for entities in relevant jurisdictions.
• I have searched ICIJ's Offshore Leaks database for any of the entities or individuals involved.
• I have searched OCCRP's Aleph platform for relevant documents.
• I have identified a partner organisation in the key foreign jurisdiction with local knowledge and language capability.
• I have assessed whether collaboration under embargo is appropriate and discussed this with my editor.
• I have checked whether any individuals involved appear on UK, EU, or US sanctions lists.
• I have considered whether to make a referral to the FCA, HMRC, or National Crime Agency alongside publication.
• I have sought legal advice on defamation risk in each jurisdiction where the story will be published or accessed.

Common mistakes

• ›Stopping at the first layer of a corporate structure — beneficial ownership may be three or four layers deep.
• ›Not checking whether nominee directors are being used — the named directors may not be the real controllers.
• ›Assuming that because a jurisdiction is a UK Overseas Territory or Crown Dependency, its records are accessible in the same way as UK records — they are not.
• ›Not seeking legal advice on defamation risk in the foreign jurisdictions where your story will be published or read.
• ›Failing to coordinate publication timing when working with international partners — staggered publication allows subjects to respond to the first story before the others land.
• ›Contacting a foreign regulatory body in a way that tips off the subject before publication.
• ›Relying on translation tools for documents in other languages without having a native speaker verify key passages.
