A cross-border acquisition closes on a Tuesday. The escrow agent releases funds on Wednesday. On Thursday, a routine post-closing screen flags that an intermediate holding company in the ownership chain of the seller has a beneficial owner who appears on the SDN List (OFAC's list of Specially Designated Nationals and blocked persons). The funds have moved. The wire passed through a US correspondent bank. Every party to the transaction – buyer, seller, escrow agent, and the correspondent – is now asking the same question: was that payment a violation of US sanctions law?
Payment and escrow structuring under OFAC legal support means designing, reviewing, and executing the payment mechanics of a cross-border transaction so that no step creates an unlicensed transfer of funds to or for the benefit of a blocked person, a designated entity, or a prohibited jurisdiction. The governing authority is the Office of Foreign Assets Control, which administers US economic sanctions under IEEPA and related statutes. Where a US person – or any party routing through the US financial system – is involved, the analysis is mandatory, not optional.
This page sets out the OFAC payment prohibitions that govern escrow and fund-flow architecture, how the analysis differs under OFSI and the EU, the risk flags that practitioners see most often, and how Calder & Vance assists clients structuring or reviewing payment arrangements across the major sanctions regimes. As of February 2026, OFAC's enforcement posture on transaction structuring remains active, with payment-channel and escrow failures continuing to feature in the agency's published enforcement activity.
What does OFAC actually prohibit in a payment or escrow arrangement?
OFAC prohibits any transfer of funds that constitutes a "dealing in" blocked property or that provides goods, services, or financial value to a blocked person or a prohibited jurisdiction. The prohibition runs to US persons wherever they are located, and to any transaction that touches the US financial system – including any wire that passes through a US correspondent bank, clears in US dollars, or uses a US payment platform.
For escrow arrangements, the core question is whether the escrow itself holds, releases, or transfers blocked property. A licensed US escrow agent holding funds on behalf of a party with a blocked beneficial owner is holding blocked property. Releasing those funds – even to a non-listed party – can constitute an unlicensed dealing. The analysis does not stop at the direct counterparty. OFAC's 50 percent rule (treating entities owned 50 percent or more in the aggregate by blocked persons as themselves blocked) runs through the ownership chain of every payee and every beneficiary of an escrow release.
Payment structuring must therefore address three distinct choke-points. First, the identity of the payee and its ownership chain. Second, the currency and clearing route – US dollar payments clear through New York regardless of the nationalities of the parties. Third, the involvement of any US financial institution as correspondent, intermediary, or account bank. Any one of these can bring an otherwise foreign transaction squarely within OFAC's reach.
How does the ownership-and-control test affect escrow beneficiaries?
The 50 percent rule is OFAC's mechanical ownership test: if blocked persons own, directly or indirectly, 50 percent or more of an entity in the aggregate, that entity is treated as blocked even if it does not appear on the SDN List. Escrow beneficiaries and payment recipients must be cleared against this test, not merely screened against published lists.
Aggregation is where escrow transactions most often go wrong. Two listed individuals each holding a 28 percent stake in a target company produce a combined 56 percent holding – above the threshold – without either triggering a direct list match. Standard automated screening that checks the entity name against the SDN List will not surface this. The only reliable method is a layered ownership analysis that traces each material shareholder back to its ultimate beneficial owners and applies the 50 percent test at every level.
In our experience, this analysis is most frequently omitted in time-pressured M&A closings where the escrow mechanics are finalised before the beneficial-ownership screen is complete. Compressed deal timelines create exactly the pressure that produces incomplete checks. We regularly advise clients to front-load ownership screening to the pre-signing phase, so that the escrow structure can be designed around confirmed, clean counterparties – or adjusted if the screen produces a hit.
What happens when the ownership chain is unclear? Gaps in corporate disclosure – common in jurisdictions with weak registry requirements – do not resolve the risk. OFAC does not accept "we could not identify the owner" as a defence to a strict-liability violation. Where ownership is genuinely opaque, the appropriate response is to seek representations and warranties, obtain enhanced diligence materials, and in appropriate cases to consult with OFAC directly before proceeding.
How do OFSI and the EU treat escrow and payment structuring differently?
Under OFSI and the EU, the payment prohibition extends beyond the 50 percent ownership test to capture entities and individuals subject to an ownership and control test – meaning that a non-listed entity over which a listed person exercises significant control (without necessarily holding 50 percent of the shares) can also be caught. This is the single most important structural divergence between the OFAC regime and its UK and EU counterparts.
For a cross-border transaction involving parties in the United States, the United Kingdom, and one or more EU member states, the payment and escrow structure must satisfy all three regimes simultaneously. A payment architecture that clears the OFAC 50 percent test can still be prohibited under OFSI or the applicable EU regulation if a listed person exercises control over the payee – through board composition, veto rights, contractual dominance, or operational dependence – without meeting the ownership threshold.
The practical consequence is that a single-jurisdiction screen is insufficient for any transaction with a UK or EU nexus. In our cross-border practice, we map the control analysis under each applicable regime separately, because the control indicators that matter to OFSI and the EU General Court are not the same as the factors OFAC considers. A structure cleared by one analysis can be caught by another.
Currency routing adds a further layer. A transaction denominated in euros or sterling that passes entirely between EU or UK parties might appear to have no US nexus. But if any party in the chain – a correspondent bank, a payment processor, or an escrow agent – has US operations or uses US infrastructure, the OFAC analysis re-enters. We regularly advise on this intersection for clients who assume their transaction is outside OFAC's reach because it involves no US parties as principals.
The bridge between these two analyses matters. The position above covers the standard multi-regime case. Your specific facts – the identities of the principals, the currency and clearing path, the jurisdictions of incorporation of the escrow agent, and the regulatory affiliations of the correspondent banks involved – change the analysis materially.

What are the most common risk flags in OFAC payment and escrow structuring?
Payment and escrow structures fail OFAC compliance most consistently at five identifiable points. Understanding each is the starting position for any effective pre-closing review.
- Incomplete beneficial-ownership mapping. The 50 percent rule runs through unlimited layers of ownership. A single missed intermediate holding company with a blocked beneficial owner is sufficient to block the payment.
- US dollar clearing. Any payment denominated in US dollars clears through the US correspondent banking system. This gives OFAC jurisdiction over the transaction regardless of the nationalities or locations of the principals. Parties who believe they are operating outside the US are routinely surprised by this.
- Escrow agent jurisdictional exposure. A US-regulated escrow agent holding funds on behalf of any party with OFAC exposure holds blocked property. Its obligation is to freeze, not to release. Selecting an escrow agent without assessing its regulatory status and its own OFAC compliance protocols creates a structural vulnerability.
- Post-closing transfers from undisclosed sources. In earn-out arrangements, deferred consideration structures, or multi-tranche payments, the beneficial ownership of the payee can change between the initial screen and the date a payment is released. A single pre-closing screen is not sufficient where the payment schedule extends over months or years.
- Contractual payment provisions that do not account for blocking. Purchase agreements and escrow instructions drafted without OFAC input often lack a compliant mechanism for handling a blocking event. When funds are frozen, the parties discover that the contract provides no commercially workable path forward.
A sixth risk flag deserves separate mention. Where a transaction involves a general licence (a standing authorisation that permits a defined category of transactions without a separate application), the scope of that licence must be confirmed before the payment is made. General licences have conditions, limitations, and expiry terms. Assuming a licence covers a transaction without verifying its terms against the specific facts is a compliance failure, not a defence.
When does an escrow or payment structure require a specific OFAC licence?
A specific licence (a case-by-case authorisation to conduct an otherwise prohibited transaction) is required whenever a proposed payment or escrow release cannot be brought within a general licence and involves a blocked person, a blocked entity, or a prohibited jurisdiction. The application is made to OFAC and must demonstrate a sufficient policy basis for OFAC to exercise its licensing discretion.
Licences are not guaranteed. OFAC exercises discretion, and the strength of the application depends on the quality of the facts presented, the adequacy of the conditions proposed, and the coherence of the legal analysis supporting the application. In our experience, applications that are submitted without a clear identification of the applicable OFAC licensing policy basis, or without complete supporting documentation, are returned with requests for additional information that add significantly to the processing time.
The timeline for a specific licence application is not fixed by statute, and we address it qualitatively: straightforward applications under a well-established licensing policy can be resolved in weeks; complex or novel applications can take considerably longer. For transactions with hard closing deadlines, the licence application must be initiated early, and the transaction timeline must be built around OFAC's review rather than around deal convenience.
An alternative in some cases is a no-action or compliance review, where a party presents the facts to OFAC informally and seeks a statement on whether the contemplated activity is consistent with OFAC's regulations. This route is appropriate where the legal question is genuinely uncertain and the stakes are material. It is not a substitute for a licence where a licence is required.
If a transaction has already been flagged, or a filing has been refused, an early review can preserve options that narrow with time. For urgent matters, contact Calder & Vance at info@caldervance.com.
What is the voluntary self-disclosure position if a payment has already been made?
Where a payment has been made and a subsequent review suggests it may have constituted an unlicensed dealing in blocked property, the question of voluntary self-disclosure – or VSD (a proactive disclosure to OFAC of an apparent violation before the agency becomes aware of it) – arises immediately. A timely, accurate, and complete VSD is a significant mitigating factor in OFAC's penalty analysis. It does not eliminate liability, but it is one of the factors that OFAC weighs in determining the severity of any civil monetary penalty.
The decision to self-disclose is not straightforward. A VSD that is incomplete, inaccurate, or that covers only part of the apparent violation can be treated as an aggravating factor. The scope of the VSD – which transactions it covers, which period it addresses, which parties are named – is a legal judgment, not an administrative formality. Counsel should be involved before a VSD is submitted, not after.
Where the apparent violation also involves a US financial institution as correspondent or intermediary, there is a separate institutional reporting dynamic. The correspondent bank may have its own disclosure obligations or internal escalation procedures that affect the timeline within which the primary parties can act. We regularly advise clients at this intersection, mapping each institution's position and sequencing the response to protect the client's interests within the overall disclosure picture.
Record-keeping is a parallel obligation. OFAC requires that records relating to any transaction subject to its regulations – including transactions that were blocked, rejected, or the subject of a licence – be maintained for five years. This obligation runs from the date of the transaction, and it applies even where the underlying transaction was ultimately licensed or cleared.
How Calder & Vance structures its payment and escrow advisory work
Our approach to payment and escrow structuring under OFAC is built around four sequenced workstreams, each of which can be engaged separately depending on the stage of a transaction.
The first workstream is pre-transaction screening and ownership mapping. We screen the counterparty and ownership chain, surface secondary-sanctions risk, and structure the transaction to avoid prohibited payment flows before they are locked into the deal mechanics. This is the most efficient point at which to resolve OFAC issues – before the escrow instructions are agreed and before the correspondent bank receives the wire instructions.
The second workstream is payment architecture review and drafting. We review the payment and escrow provisions in the transaction documents – the purchase agreement, the escrow instructions, the correspondent banking arrangements – and identify any provision that creates an unlicensed risk or that lacks a workable mechanism for a blocking event. We then propose specific drafting amendments that address the identified risk.
The third workstream is licensing and authorisation support. Where the transaction requires a specific licence, we assess eligibility, prepare and submit the licence application, and manage OFAC's queries throughout the review process. We maintain ongoing oversight of the transaction timeline to ensure that the closing mechanics are sequenced around the expected licence outcome.
The fourth workstream is post-event response. Where a payment has been made and a potential violation has been identified, we scope the apparent violation, advise on voluntary self-disclosure, and prepare the penalty defence. This workstream also covers the record-keeping obligations that run from the date of the event.
In a recent matter, a financial-services business involved in a multi-party cross-border payment arrangement discovered, after closing, that a beneficial owner of one of the payees appeared on the SDN List. We scoped the apparent violation, mapped the involvement of each institution in the payment chain, assessed the VSD position, and advised on the disclosure strategy. The matter was resolved within OFAC's published framework for self-disclosed violations. We make no representation as to outcome in any future matter.
Across all four workstreams, our cross-border coverage means that where the OFAC analysis intersects with OFSI or EU obligations – as it does in most significant cross-border transactions – we address all three regimes under one instruction, rather than requiring a client to coordinate between separate advisers. This is particularly valuable where the payment structure involves counterparties in multiple jurisdictions and the control analysis differs materially between regimes.
