Evidencing the absence of control under OFAC: legal support

A multinational holds a minority stake in a foreign operating company. A designation falls on one of its co-shareholders. Overnight, the operating company's accounts are frozen, suppliers stop shipping, and the client's own treasury team begins asking whether the group itself is now blocked. The question is not abstract. It decides whether the business can continue trading at all.

Evidencing the absence of control under OFAC is the discipline of demonstrating, with structured legal and factual analysis, that a non-listed entity is neither owned nor controlled by a blocked person in a way that triggers the 50 percent rule (OFAC's rule treating any entity owned 50 percent or more in the aggregate by one or more blocked persons as itself blocked). Where the rule does not apply on its face, a well-constructed evidence package addressed to OFAC can confirm that position – or, where the position is genuinely uncertain, resolve it before a transaction is lost. As of January 2026, OFAC continues to scrutinise ownership chains with increasing depth, and the burden of making the case falls on the party seeking certainty.

This page explains the legal basis for the control test, the evidence a successful package requires, where OFAC's approach diverges from OFSI and the EU, and how Calder & Vance assists clients through this process.

What is the pain: frozen assets and blocked business

A designation – or even the credible risk of one – can halt a transaction without warning. Banks decline to process payments. Counterparties invoke force majeure clauses. Buyers walk away from signed contracts. The damage is immediate and, in many cases, measurable in days rather than weeks.

The underlying legal position under OFAC is strict. Civil liability attaches on a strict basis: no knowledge of a violation is required for it to occur. That means a business that continues trading with a company that is in fact captured by the 50 percent rule is exposed to significant civil penalties, regardless of its good faith. The incentive to resolve the question quickly is acute.

In our experience, the hardest moment for a General Counsel is not receiving the designation notice itself. It is the period of uncertainty that follows – when the ownership chain has not been fully mapped, when the question of control has not been answered, and when the business must decide whether to proceed, pause, or restructure. Delay compounds the problem. The longer the uncertainty persists, the more counterparties treat the company as effectively blocked.

Acting quickly, and acting with a structured evidentiary approach, is the difference between a matter that resolves in weeks and one that drags into months of commercial paralysis. That is what evidencing the absence of control under OFAC legal support is designed to achieve.

The governing regime: how OFAC applies the 50 percent rule

OFAC's authority derives from the International Emergency Economic Powers Act (IEEPA) and the Trading with the Enemy Act (TWEA), administered through programme-specific regulations. The 50 percent rule operates independently of whether a non-listed entity is itself designated: if the threshold is met, the entity is treated as blocked by operation of law, without any formal act by OFAC.

The rule aggregates across all blocked-person shareholders. Two listed persons each holding a 30 percent stake in the same company reach the threshold together, even where neither does so alone. Layering through intermediate holding structures does not dilute the calculation. OFAC looks through layers to identify the ultimate beneficial ownership position.

Critically, the rule is a floor. OFAC's guidance, as currently in force, confirms that the 50 percent threshold is a minimum indicator, not a safe harbour. A holding below that line does not automatically confirm the entity is free of restrictions. OFAC may look at practical and economic control – including board composition, veto rights over material decisions, contractual power to direct management, and funding dependency – as part of a broader assessment. In a 2026 guidance update, OFAC has confirmed that it looks past legal form to the practical and economic reality of a transaction, and that sham and disguised arrangements are subject to close scrutiny.

For a business that holds a stake below 50 percent, or that sits in the supply chain of a company with a blocked minority shareholder, the question is therefore not resolved by pointing to the share register alone. The evidence package must address the full picture.

How does OFAC's approach compare with OFSI and the EU?

The mechanical ownership threshold that defines OFAC's 50 percent rule does not translate directly to its UK and EU equivalents – and the divergence has practical consequences for any cross-border business facing a designation on one side of the Atlantic.

Under OFSI and the relevant UK regulations, the ownership and control test can catch a non-listed entity that is controlled by a designated person, even where the ownership stake falls below any fixed percentage. UK case law, as currently in force, distinguishes between existing influence and a hypothetical ability to exert control: the test is actual control, not theoretical capacity. Board composition, contractual rights, and the ability to give binding directions to management are all relevant. A minority shareholder with contractual veto rights over key operational decisions may satisfy the UK control test even holding 20 or 30 percent.

The EU position is similar in structure. Under the relevant Council Regulation, the ownership criterion for asset-freeze purposes looks at an ownership of more than 50 percent, alongside a separate control limb. An EU court ruling has confirmed that control must be proved by objective and sufficiently weighty evidence, and that the character of a third party's political or commercial relationship with a designating state is not by itself sufficient. The standard is demanding, but the test is qualitative in a way that OFAC's arithmetic threshold is not.

For a client facing parallel US and EU exposure – which is common in financial services, energy, and manufacturing – the same factual matrix will be assessed under different tests. What resolves the OFAC question may not resolve the EU or UK question. We regularly advise on this intersection, and in our experience, a combined evidence package designed to address all three tests simultaneously is significantly more efficient than preparing three separate submissions.

There is a further divergence worth noting. Under OFAC, the 50 percent rule operates by operation of law: no designation decision is required to create the blocking effect. Under the EU and UK regimes, the control test generally requires a determination by the competent authority, or a legal challenge, before the effect attaches. The practical speed of risk materialisation is therefore different, and the appropriate response strategy differs accordingly.

What does a strong evidence package contain?

An effective absence-of-control submission to OFAC is a structured legal memorandum accompanied by primary documentary evidence. It is not a letter asserting that the entity is not blocked. OFAC will not act on assertion alone.

The core elements of a well-constructed package are:

• A complete ownership map, tracing all direct and indirect holdings to the ultimate beneficial owner level, covering all classes of shares, voting rights, and economic interests. The map must account for recently acquired, pledged, or encumbered interests.
• An analysis of the aggregation position, confirming whether any combination of blocked-person holdings reaches the 50 percent threshold, and addressing the position at each layer of any intermediate structure.
• An analysis of the control position, covering board composition and appointment rights, contractual veto rights, material agreements between shareholders, and any management service agreements that may give a blocked person direction over the entity's operations.
• Primary documentary support: constitutional documents, shareholder agreements, board resolutions, and register extracts. Official documents from the relevant company registry, where available, carry significant weight.
• An assessment of economic dependency, addressing whether the entity is funded primarily by blocked-person flows, whether its contracts or revenues are channelled through blocked-person intermediaries, and whether any restructuring since the designation altered the effective control position.
• A legal opinion applying OFAC's guidance to the factual matrix. The opinion must be clean and consistent: any internal contradiction will attract scrutiny.

Where the position is genuinely uncertain – for example where a blocked person holds 40 percent and contractual control rights that are ambiguous – a specific-licence application or a request for a formal guidance determination from OFAC may be the appropriate route alongside, or instead of, a straightforward absence-of-control submission. The choice of route is a legal judgment that should be made with sanctions counsel.

Record-keeping is not an afterthought. Under applicable rules, sanctions records must be kept for five years. The evidence package, all correspondence with OFAC, and any underlying diligence files form part of that record. A well-maintained record is also a mitigating factor if OFAC subsequently revisits the matter.

What are the risk flags that require urgent attention?

Certain facts in the ownership and control picture materially increase the risk that OFAC will treat an entity as blocked, and require early identification rather than post-hoc correction.

The first is recent change. A shareholder register that has been amended in the period shortly before or after a designation is a significant red flag. OFAC's guidance on sham and disguised transactions, updated as currently in force, makes clear that structural changes timed to move beneficial ownership out of a blocked person's hands will be scrutinised closely. The timing of any restructuring must be explained and documented; a gap in the paper trail is not curable by assertion.

The second is nominee arrangements. Where a shareholder of record holds on behalf of another person, the economic and voting rights sit with the beneficial owner, not the nominee. OFAC looks through nominee structures to the underlying ownership position. A company that relies on a nominee register as its answer to the ownership question has not answered the question.

The third is funding dependency. An entity that is economically dependent on blocked-person funding – whether through intercompany loans, management fees, or the direction of operational revenues – may be caught by the control analysis regardless of the ownership position. The absence of a direct shareholding does not remove the risk where the practical economic reality is that the entity operates as an extension of the blocked person's interests.

The fourth is parallel exposure. A business operating in a sector with significant EU or UK nexus may face a control determination under those regimes even while the OFAC position is being managed. As noted above, the tests diverge. Resolving the OFAC question without simultaneously addressing the EU and UK position leaves a gap that counterparties – particularly financial institutions – will notice. Does your compliance programme address all three regimes, or only the most visible one?

The fifth is the counterparty's own exposure. A business that relies on a third party's statement that it is not blocked, without conducting its own diligence, takes on the risk of that statement being wrong. OFAC's strict-liability standard means that a good-faith reliance on incorrect information does not eliminate the exposure. Screening a name is not the same as analysing an ownership chain.

When does the delisting myth cost businesses time and money?

A common misconception among clients who are not sanctions specialists is that a delisting, or a confirmed absence-of-control determination, is automatic once the relevant facts change. It is not.

OFAC's processes are initiated by the party seeking relief. OFAC does not monitor ownership chain changes in real time and does not proactively update the blocked status of non-listed entities as shareholders are added or removed. A company that was captured by the 50 percent rule at the point of a co-shareholder's designation remains in a legally ambiguous position until the ownership and control analysis is completed, documented, and, where appropriate, submitted to OFAC for confirmation.

In practice, that means a company whose blocked co-shareholder subsequently divests its stake needs to conduct a fresh ownership analysis, prepare updated documentation, and in many cases submit a new request to OFAC. The divestment alone does not clear the record. We have acted for clients who discovered, sometimes months after a co-shareholder transaction, that counterparties and correspondent banks were still treating them as effectively blocked because no formal confirmation had been sought.

The process is not instantaneous. Specific-licence timelines – and informal guidance timelines – vary widely and depend on the complexity of the matter, the quality of the submission, and the programme under which the designation falls. A submission that is incomplete, or that raises more questions than it resolves, will delay the process significantly. The value of a well-prepared first submission is precisely that it avoids the back-and-forth that extends timelines.

Delisting timelines under any regime are measured in months, not days. They are not guaranteed. But the quality and organisation of the evidence package is the single factor most within a client's control.

How Calder & Vance supports absence-of-control matters

Our practice in evidencing the absence of control under OFAC covers the full sequence from initial ownership analysis through submission management and follow-on engagement with the regulator.

For a business facing an immediate commercial question – a deal that cannot close, a payment that has been frozen, a supplier that has suspended shipments – we assess the ownership and control position quickly and advise on whether the entity is, in our analysis, captured by the 50 percent rule or the control analysis. That initial assessment determines the route: a clean absence-of-control submission, a specific-licence application, a request for informal guidance, or a combination.

We then build the evidence package: map the ownership chain to the ultimate beneficial owner level, review constitutional and shareholder documents, analyse all control rights and material agreements, identify and address the risk flags noted above, and prepare the legal memorandum. Where documents require translation or official authentication from a foreign registry, we manage that process and coordinate with local counsel in the relevant jurisdiction.

For clients with simultaneous EU or UK exposure, we prepare a combined analysis that addresses the OFAC, OFSI, and EU control tests on the same factual matrix. That is typically more efficient and more consistent than three separate engagements.

In a recent matter, a manufacturing business held a minority stake in a target company whose majority shareholder became designated under a US programme. The client's counterparties – including two financial institutions – had frozen the target's accounts. We mapped the ownership chain across five intermediate holding structures, identified that the aggregated blocked-person interest fell below the 50 percent threshold and that no contractual control rights of the required character existed, and prepared a comprehensive absence-of-control submission. The matter progressed toward a resolution of the commercial freeze. No outcome is guaranteed, but the quality and speed of the submission materially advanced the client's position.

The position above covers the standard case. Your facts – the ownership structure, the jurisdiction of incorporation, the contractual arrangements, and the programme in play – change the analysis materially. If the position is uncertain, or if a transaction has already been blocked pending the answer, an early review can preserve options that narrow with time.
