Building the delisting evidence package under OFAC: specialist advice

A company's name appears on the SDN List (OFAC's list of Specially Designated Nationals and blocked persons). Its bank accounts are frozen. Counterparties cancel contracts. Correspondent banking disappears overnight. The question that follows is not whether the designation hurts – it does, immediately and severely – but whether the evidence exists to challenge it, and whether it can be assembled in a form that OFAC will act on. As of March 2026, building that evidence package remains the single most consequential step in the administrative delisting process.

Building the delisting evidence package under OFAC means constructing a structured, documented submission to the Office of Foreign Assets Control that demonstrates the legal and factual basis for removing a name from the SDN List. The applicable authority is OFAC, operating under IEEPA and the relevant thematic sanctions regulations. The quality and precision of that package – not the political salience of the designation – determines whether a reconsideration petition (a formal request to OFAC to re-examine the grounds for designation) succeeds or stalls.

This page sets out who administers the OFAC delisting process, how the evidence package is constructed, where cross-border complexity enters the analysis, what the most common errors are, and how Calder & Vance approaches each stage of the work.

Who administers OFAC delisting, and what is the legal basis?

OFAC administers the SDN List under authority derived from IEEPA and, for certain programmes, the Trading with the Enemy Act. The delisting route available to a designated person is an administrative reconsideration petition submitted directly to OFAC. There is no automatic right to an oral hearing. The process is written, structured, and assessed internally by OFAC's licensing and policy staff.

The legal standard OFAC applies when reviewing a petition is whether the petitioner has provided information that, taken together, demonstrates that the designation criteria are no longer met or were not met in the first instance. That is a high bar. OFAC is not required to accept assertions; it evaluates evidence. A petition that restates the designation notice and asks OFAC to reconsider without new material rarely moves the case forward.

Reconsideration is distinct from judicial review. A designated person may challenge a designation in the US federal courts under the Administrative Procedure Act, arguing, for instance, that the decision was arbitrary, unsupported by substantial evidence, or procedurally deficient. In our experience, the two routes are not mutually exclusive, but the evidence package built for the administrative petition is also the foundation for any subsequent litigation. Starting with the petition disciplines the factual development of the case.

Timelines in the administrative process are not set by statute for the standard petition. OFAC has no published mandatory response deadline in the general case. In practice, review periods vary considerably depending on the programme, the volume of submissions, and the complexity of the matter. Clients should plan for a process that takes many months rather than weeks, and they should assume that OFAC may request supplemental information before issuing a decision.

What does the delisting evidence package contain?

The evidence package is the core of the petition. It is not a cover letter with attachments. It is a structured legal and factual submission that addresses each basis stated in the designation notice and provides documentary support for every material assertion.

The package typically contains several distinct components. First, a legal memorandum that identifies the applicable designation criteria, maps each criterion against the asserted factual basis in the notice, and argues why that basis is factually incorrect, legally insufficient, or no longer operative. This section requires close reading of the designation notice alongside the publicly available regulatory criteria for the programme in question.

Second, a factual narrative that tells the story of the designated party – its business, its ownership, its transactions – in a way that is consistent with the documentary evidence and that directly addresses each ground for designation. The narrative must be honest and complete. OFAC will compare it against information it already holds. Inconsistencies damage credibility and can be used against the petitioner.

Third, the documentary evidence itself: corporate records, financial statements, transaction records, correspondence, and – where the designation rests on an asserted relationship with another person or entity – evidence that demonstrates the nature and limits of that relationship. Ownership charts that clearly show the structure of a corporate group, and that are supported by official registry documents, carry significant weight.

Fourth, declarations or sworn statements from individuals with direct knowledge of the relevant facts, where documentary evidence alone is insufficient to establish a point. These declarations must be careful. They must not overreach. Anything that cannot be verified independently should not be asserted in a sworn statement.

Fifth, in some matters, expert analysis – financial, commercial, or technical – that contextualises transactions or patterns that might otherwise appear suspicious. In a recent matter, a trading business faced designation grounds that rested partly on an inference drawn from payment routing. We commissioned independent analysis of the commercial rationale for that routing pattern, submitted it as part of the package, and the inference was materially weakened in the subsequent correspondence. The outcome of that matter was not guaranteed, but the evidence shifted the analysis.

The position above covers the standard case. Your facts – the programme, the counterparty relationships alleged, the documentary trail available – change the analysis at every point. For an assessment of your specific situation, contact Calder & Vance at info@caldervance.com.

How does the OFAC process compare with UK and EU delisting routes?

Building an OFAC delisting evidence package in isolation is rarely the right approach for a cross-border business. The same person or entity is frequently designated under multiple regimes simultaneously, and the grounds stated in each designation notice may differ. The evidence developed for one petition can support – or, if handled carelessly, contradict – submissions under a parallel regime.

Under OFSI (the Office of Financial Sanctions Implementation in the United Kingdom), the equivalent process is a written request for delisting addressed to the Secretary of State via OFSI. The UK process operates under the Sanctions and Anti-Money Laundering Act ("SAMLA") and the relevant thematic sanctions regulations. Unlike the OFAC administrative petition, a UK designation may also be challenged by judicial review in the High Court, and there is a statutory review mechanism under SAMLA. The evidentiary standard and the institutional audience differ from the OFAC process. Documentation that is persuasive in Washington may need to be reframed and supplemented for London.

At the EU level, designated persons may apply to the Council of the EU for de-listing, and they retain the right to bring an annulment action before the EU General Court. The Court has developed a body of procedural case law on the rights of the designated party, including the right to be provided with a statement of reasons and to have the opportunity to submit observations. Evidence packages for EU proceedings are shaped differently from OFAC petitions: the legal argument tends to occupy more space, and the procedural dimensions – notice, rights of defence, proportionality – carry more independent weight.

For a designated multinational or individual with exposure under all three regimes, coordinating the evidentiary strategies is critical. An admission made to facilitate a EU delisting could create complications in the OFAC process if the two submissions are not considered together. We regularly advise clients on multi-regime designation situations, and in our experience the evidence package is always planned at the portfolio level, not programme by programme.

Beyond the US, UK, and EU, designations under the UN Consolidated List introduce a further layer. The UN Ombudsperson mechanism is available for certain listed individuals and entities. That process has its own evidential requirements and timelines. Where a UN designation underpins a domestic designation, the UN process may need to run alongside or before the domestic petitions.

If a transaction has already been flagged, or a petition has been refused, an early review of the multi-regime position can preserve options that narrow with time. Write to us at info@caldervance.com.

What are the most common errors in building an OFAC delisting evidence package?

The most common error is submitting too quickly with too little. A petition submitted before the evidence has been fully gathered and assessed gives OFAC a document that it can assess negatively, and a negative first response makes the subsequent process harder. The reconsideration mechanism does not preclude a second submission, but momentum is lost and OFAC's initial reading of the matter is established.

The second frequent error is addressing only the stated grounds and ignoring the unstated ones. Designation notices often describe the basis in summary form. Practitioners advising on OFAC matters note that OFAC's file typically contains more material than the notice discloses. A petitioner who addresses only the stated grounds and ignores the broader factual picture presented in OFAC's administrative record leaves gaps that can be used against them.

Third, and closely related: submitting evidence without a legal framework. A collection of corporate documents and declarations is not a petition. Every piece of evidence must be linked, in the legal memorandum, to a specific criterion and a specific assertion in the notice. OFAC staff are not conducting independent research on behalf of the petitioner. They assess what is in front of them.

Fourth, documentary inconsistencies. Corporate records that contradict the narrative, financial statements that show flows inconsistent with the stated business activity, or declarations that are internally inconsistent do more damage than the absence of evidence. Thorough pre-submission review of all materials is essential.

Fifth, insufficient attention to the 50 percent rule (OFAC's rule treating entities owned 50 percent or more by blocked persons as themselves blocked) when the designation rests on an ownership-based theory. Where a client disputes that the relevant ownership threshold was ever met, the evidence package must map the ownership structure with complete documentary support. Incomplete ownership charts that leave any link in the chain undocumented are a common source of rejection.

Sixth, ignoring the reputational and commercial consequences of the petition itself. A petition to OFAC is not confidential in the sense that the outcome, once reached, may inform subsequent regulatory interactions with other counterparties or regulators. The framing of the submission – what is asserted and how – has consequences beyond the OFAC decision. We have acted for clients who were focused entirely on the outcome of the OFAC petition without considering how the same narrative would be read by a bank reviewing their account relationship. The two considerations must be addressed together.

The ownership and control question: when does the 50 percent rule need to be rebutted?

Where a designation rests on the theory that a person or entity is subject to the 50 percent rule, the evidence package must directly rebut that theory. This means producing documentary evidence of the full ownership chain, from the top-level shareholders through every intermediate holding structure, with official registry documents supporting each link.

The 50 percent rule is mechanical under OFAC. Ownership is aggregated across all blocked persons who hold interests in the same entity. If two blocked persons each own twenty-six percent of a company, the company is blocked, even if no single blocked person exceeds the threshold alone. The evidence package must address aggregation expressly: it is not enough to show that no single blocked person holds a majority.

The UK and EU approaches introduce a control test that does not exist in the OFAC rule. Under OFSI and the EU ownership and control rules, an entity may be caught even where the ownership threshold is not met, if a listed person exercises control over it – for example, through board representation, veto rights, or contractual arrangements. This divergence is practically significant for a business that needs to demonstrate independence from a designated person under both OFAC and OFSI simultaneously. The evidence package may need to show not only that ownership is below the threshold, but also that no control relationship exists. That requires a different set of documents: board minutes, shareholder agreements, governance records.

Does your corporate group hold any interest that was, at any point, traceable to a currently designated person? If so, the ownership and control analysis should be treated as a live question even before a formal designation, as part of ongoing sanctions due diligence.

Risk flags and when to involve specialist counsel

Certain features of a matter should prompt immediate specialist review rather than internal preparation of the petition. The first is a designation under a programme with extraterritorial reach, where secondary-sanctions risk means that third parties in unrelated jurisdictions may be exposed by continued association with the designated entity during the petition process. Managing those third-party relationships while the petition is pending requires specific advice that is separate from the evidence-building work.

The second is a simultaneous designation under two or more regimes. Coordinating submissions without internal contradiction requires someone with oversight of all streams at once. The risk of an inadvertent inconsistency – an assertion made in the OFAC petition that is difficult to sustain in the EU proceedings – is real and material.

The third is a designation that followed a prior enforcement matter, a voluntary self-disclosure (a VSD – a pre-emptive report of an apparent violation to the regulator), or a settlement. In those cases, the factual record that OFAC holds is more developed, and the petition must be drafted with full awareness of what is in that record.

The fourth is time pressure. Where a designated entity has contractual deadlines, licensing obligations, or counterparty agreements that are being terminated as a consequence of the designation, the speed of the petition matters. A poorly prepared fast petition is worse than a well-prepared slower one, but there are steps – including engagement with OFAC on the specific licence route and the filing of an initial statement of intent – that can preserve positions while the full package is assembled.

In our experience, the matters that go wrong most often are those where the designated person or their general counsel begins building the submission without a comprehensive strategy for the full evidentiary record, and then encounters documentary problems – ownership gaps, inconsistent records, undisclosed relationships – that require the work to be substantially redone. Early specialist involvement typically shortens the overall process and improves the quality of the package materially.

One common myth worth addressing directly: some designated parties believe that the strength of their business case – the economic harm of the designation, the disruption to legitimate trade – is itself sufficient to secure delisting. It is not. OFAC's process is legal and factual, not economic. The harm caused by a designation is not, by itself, a ground for removing it. The package must address the legal criteria for designation and demonstrate that they are not, or are no longer, satisfied. The economic consequences of the designation may be relevant to certain procedural arguments, but they do not substitute for the evidentiary work.

How Calder & Vance builds the delisting evidence package

Our approach to building an OFAC delisting evidence package begins with a full review of the designation notice, the regulatory programme, and all available information about the basis for designation. We do not begin drafting the petition until we understand what OFAC's file is likely to contain and what the principal evidential challenges are.

We then work through the ownership and control structure with the client to produce a complete and accurate map of the corporate group, supported by official registry documents and, where necessary, independent verification. We identify any gaps or inconsistencies in the documentary record before submission, not after. That pre-submission audit is one of the most time-intensive parts of the work, and in our practice it is the part that most often determines the outcome.

We draft the legal memorandum, the factual narrative, and – where appropriate – the expert or declarant materials in parallel, so that the submission is coherent and internally consistent rather than assembled from separately drafted components. We review all materials for consistency with the client's parallel regulatory and commercial positions before the package is finalised.

Where the matter has a multi-regime dimension, we assess eligibility, prepare and submit the petition, and manage OFAC's queries, and we coordinate the legal strategy across the UK, EU, and other applicable regimes. Local counsel in the relevant jurisdiction is engaged where the matter requires it.

We advise on the specific licence (a case-by-case authorisation to conduct an otherwise prohibited transaction) route as a parallel track where time pressure or commercial necessity requires it, and we manage the interaction between the licence application and the delisting petition so that neither undermines the other.

Frequently asked questions

How long does building the delisting evidence package take under OFAC?
There is no fixed statutory timeline for OFAC to respond to a reconsideration petition; review periods vary by programme and complexity and should be measured in months rather than weeks. The time to build the package depends on the state of the existing documentary record. Where ownership chains are clean and documentation is complete, preparation can proceed relatively quickly. Where corporate records are incomplete, inconsistent, or require independent verification, the assembly process is longer. Attempting to accelerate beyond what the evidence supports produces a weaker submission and, in our experience, a worse outcome.
What are the main risks in building the delisting evidence package under OFAC?
The principal risks are submitting prematurely with an incomplete evidentiary record, making assertions that are not fully supported by documentation, and failing to address the full factual basis that OFAC holds – which may extend beyond what is stated in the designation notice. Documentary inconsistencies between the petition and the client's own records are a frequent source of difficulty. Multi-regime matters carry the additional risk of inconsistency between parallel submissions if the evidentiary strategy is not coordinated across all proceedings from the outset.
Do we need specialist counsel for building the delisting evidence package?
Specialist counsel is not a legal requirement, but in practice the complexity of the OFAC reconsideration process – the evidentiary standards, the interaction with parallel regimes, the strategic decisions about what to assert and how to frame it – makes expert involvement material to the outcome. General corporate counsel without specific sanctions experience regularly underestimate the scope of the evidence required and the importance of pre-submission consistency checks. For matters involving multi-programme designations, secondary-sanctions exposure, or prior enforcement history, specialist involvement from the outset is particularly important.
