🇬🇧 Proliferation Financing Risk: Why Professional Firms Need to Continue Paying Attention

By Marker AI — 2026 AML Insights Series

For a long time, proliferation financing sat in the “banks and dual-use exporters” filing cabinet. Law firms and accountants could mention it in the firm-wide risk assessment, tick a box that said WMD appeared in a training slide, and get back to source of funds on the house purchase.

That’s no longer the case. Supervisors, FATF and the UK national risk picture have been clear for some years now that professional firms are not spectators. They form companies, hold client money, move property, design structures and give transactions a veneer of respectability.

Those are exactly the services a weapons procurement network needs when it can’t buy a component in its own name.

This piece is about what that it might look like in a client file.

Our partners at Lessons Learned are offering Marker network firms two top CPD accredited e-learning courses, Proliferation Financing and AML/CFT, for the price of one – £15. And if you only need one course, quote MARKER15 at checkout to get a 15% reduction on that course.

1. What proliferation financing actually looks like in a practice

Obviously, it can take many different forms. It is rarely a crate of missile parts on the reception desk. It is more often:
• a company formed for “import-export” or “general trading” with a thin website and a director who is never available;
• a property purchase funded from an overseas corporate account whose purpose does not match the story;
• a trust or holding structure that inserts e.g. a UAE, Hong Kong or Cyprus layer between a UK firm and an end user the fee-earner has never met;
• an invoice trail for “consultancy”, “logistics” or “spare parts” that is hazy about what is actually being shipped or provided;

As a professional, your job isn’t to become a sanctions analyst overnight. It is, rather, to notice when a file or matter may be being used as ‘cover’, and to stop treating things which are “not obviously criminal” as “fine”.

2. Why law and accountancy firms are useful to these networks

Banks will see a payment. Lawyers and accountants often see a story that tries to make the payment look ordinary. Company formation, registered office, conveyancing, tax advice, accounts that make a shell company look like an actual trading concern — that is the professional-enabler pattern that supervisors already know from money laundering. Proliferation financing uses the same techniques, except in the case of proliferation financing the funds are buying or disguising access to goods, technology or know-how that a sanctioned person or organization cannot acquire cleanly.

Fee-earners may not have a mental model for this. They may complete CDD, screen the directors and UBOs, file the passport scan and, with everything flashing green, miss the other red flags that require a level of awareness that’s typically another layer further down.

3. Regulatory Expectations

SRA and ICAEW expectations have not invented a new regime called “PF.” They expect the existing risk-based approach to include it: firm-wide risk assessment, matter risk, CDD that tests the true purpose of instructions, and a SAR where the suspicion threshold is met. The weakness supervisors keep finding is not the absence of a PF policy. It is a file where PF is named in the manual and invisible in the work.

In practice that means:
• purpose of the instruction is written down in words a stranger could understand;
• ownership and control are followed through the last opaque layer, not stopped at the first respectable letterhead;
• source of funds is tested against the client’s actual business, not against a bank letter that only proves money moved;
• sanctions and dual-use context are considered when the client, the counterparty or the goods have any reason to touch a restricted programme — including when the client says they are “only the UK solicitor.”

4. The questions that belong on the desk

These are not extra forms. They are the conversation the digital onboarding tool will not have for you:
• What is actually being bought, sold, moved or held — in one sentence?
• Who is the end user, and how do we know?
• Why this structure, this jurisdiction, this urgency?
• If this were about sanctions evasion rather than tax efficiency, would the file still look the same?
• Who in the firm is allowed to say no — and have they ever?

If those questions cannot be answered, the issue is not “we need a PF module.” The issue is that the matter should not proceed on the present story.

5. Digital tools and the PF file

ID&V will tell you the passport is real. It will not tell you whether Ferana Trading is a trading company or a nameplate. Screening will hit a listed person if they use their own name. Networks of this kind often do not. Human review of purpose, structure and narrative is still the control. That is the same argument we make every month about digital onboarding. Proliferation financing is simply the case where getting the narrative wrong has a different kind of consequence.

6. What “good” looks like this year

A defensible practice in 2026 can show that PF is in the firm-wide assessment for a reason, that high-risk work types (company work, property, TCSP, trade-adjacent clients) have matter questions that go beyond “PEP / sanctions list / SOF letter,” and that fee-earners have practised a “what do you do next?” decision — not only sat through a slide.

Training that never leaves the banking typology will not get you there. Neither will a policy that mentions WMD once.
