A trading company receives notice that its principal shareholder has appeared on the SDN List (OFAC's list of Specially Designated Nationals and blocked persons). Within hours, correspondent banks suspend payment rails. Suppliers halt shipments. The business is effectively frozen – not because of anything the company itself has done, but because of its ownership structure. The question that matters now is not whether the designation was expected. It is how to get off the list.
A delisting petition (formally, a request for administrative reconsideration) is the primary route by which a designated person or entity asks OFAC to remove or modify a designation. The petition is governed by OFAC's regulations under the International Emergency Economic Powers Act (IEEPA) and its published administrative-reconsideration procedures. As of early 2026, OFAC processes petitions on no guaranteed timetable, and the quality of the evidence package is the single greatest determinant of success.
This guide walks through every stage of the process – from the decision to petition, through evidence assembly, submission mechanics, post-submission management, and the broader cross-regime picture that any international business must consider alongside an OFAC petition.
Step 1: Decide whether a petition is the right route
Before drafting a word of the petition, counsel and the petitioner must assess whether administrative reconsideration is the appropriate route, or whether a parallel strategy is needed. That assessment shapes everything that follows.
OFAC has authority to designate under multiple executive-order programmes. The first task is to identify which programme or programmes underpin the designation. Each programme has different designation criteria. A petitioner who argues against the wrong criterion wastes scarce credibility with the agency.
The designation notice itself is the starting point. It will identify the legal basis. In our experience, petitioners sometimes receive a short, formulaic notice that names a programme but gives little further detail. That is deliberate; OFAC is not required to disclose classified or law-enforcement-sensitive information at this stage. The absence of detail in the notice does not mean the evidentiary record is thin – it means the petitioner must work to understand and address what the record is likely to contain.
Three threshold questions govern the decision to petition:
- Is the designation based on facts that are wrong, outdated, or capable of being recharacterised in a materially different light?
- Has the petitioner's situation changed since designation – for instance, through divestiture, restructuring, or the end of the conduct that triggered the listing?
- Is there a parallel licensing need? A person who needs to wind down blocked property, receive legal-fee payments, or take a humanitarian action may need a specific licence (a case-by-case authorisation to conduct an otherwise-prohibited transaction) alongside or before a petition.
If the designation rests on facts that are both accurate and ongoing, an immediate petition is unlikely to succeed. In that situation, counsel's role is to advise on what changes are necessary before a petition has a realistic prospect.
Step 2: Understand the evidentiary standard before you draft
OFAC will reconsider a designation where the petitioner demonstrates that the criteria for designation are no longer met, that the original designation was factually incorrect, or that changed circumstances warrant removal. The burden sits with the petitioner.
What does that mean in practice? OFAC is not a court. It does not apply rules of evidence in the judicial sense. But it does scrutinise submissions carefully, and it has access to classified information that the petitioner cannot see or rebut directly. That asymmetry is the defining challenge of every OFAC petition.
The petitioner's strategy must therefore do two things at once. First, it must present a clear, factually grounded narrative that explains why the designation criteria are not met or no longer met. Second, it must anticipate the information OFAC is likely to hold and address it proactively – not by speculating about classified material, but by providing context and documentary evidence that makes any adverse inference less sustainable.
In our cross-border practice, the most effective petitions are built around a structured factual chronology: a precise account of the petitioner's corporate history, ownership changes, business relationships, and the specific conduct that OFAC appears to have acted upon. Gaps in the chronology read as evasion. Completeness reads as credibility.
Step 3: Assemble the evidence package
The evidence package is the petition. A covering letter with broad assertions achieves nothing; the evidentiary annex is what moves the case. This is where the time and effort must go.
Core categories of evidence typically include:
- Corporate-structure documentation: current and historical ownership charts, shareholder registers, articles of association, and any restructuring documents. Where ownership has changed since the conduct at issue, the timeline of that change is critical.
- Contractual and transactional records: agreements, invoices, shipping documents, payment records, and correspondence that place the petitioner's conduct in its proper context.
- Evidence of changed circumstances: termination of relationships, sale of interests, regulatory settlements in other jurisdictions, or evidence that an associated person has ceased to exercise the influence that triggered designation.
- Third-party corroboration: where available, statements from counterparties, auditors, or regulators in other jurisdictions that support the petitioner's account. These carry weight precisely because they are independent.
- Compliance measures taken: evidence of enhanced due-diligence procedures, sanctions-compliance training, appointment of compliance personnel, and subscription to commercial screening services.
One document type deserves particular attention: the ownership and control analysis (the test for whether a non-listed entity is caught through a listed person). Where the designation flows from an ownership or control relationship, the petitioner must demonstrate with precision how that relationship has been severed or why it does not meet the relevant threshold. Under OFAC, the 50 percent rule (OFAC's rule treating entities owned 50 percent or more by blocked persons as themselves blocked) operates by ownership alone; control is a separate, additional basis for designation. Both must be addressed if both are in play.
We regularly advise clients to err toward over-documentation. OFAC reviewers cannot credit evidence they do not have. An annex that runs to several hundred pages of authenticated, indexed documents is not unusual in a contested petition.
Step 4: Draft and submit the petition
The petition itself has no prescribed form, but OFAC expects a structured submission. The covering letter should identify the petitioner, the designation being challenged, the legal basis of the challenge, and a summary of the relief sought. The body of the petition develops each argument, cross-referenced to the evidentiary annex.
Submissions are made to OFAC's Compliance and Enforcement division. The submission may be made in writing or, in some programmes, through OFAC's online portal. Petitioners should retain proof of delivery. OFAC will acknowledge receipt; it will not routinely provide substantive updates thereafter.
Two drafting points carry disproportionate weight. First, the petition must not misstate or omit material facts. OFAC takes false statements seriously; a factual error that is later identified can undermine the entire petition, regardless of the underlying merits. Second, legal argument should be tightly anchored to the designation criteria and to the evidentiary record. Rhetoric and appeals to general fairness carry no weight. Specific factual rebuttal, carefully documented, is what works.
The position above covers the standard case. Your facts – the designation programme, the ownership structure, the nature of the conduct at issue, and the regime in play – change the analysis materially.

Step 5: Manage the post-submission period
After submission, the process is largely in OFAC's hands. OFAC does not publish processing timescales, and petitions can remain pending for an extended period – sometimes measured in years for complex or contested designations. That reality must be built into the petitioner's strategy from the start.
Several things can be done during the post-submission period that affect outcomes. OFAC may send queries or requests for additional information. These must be answered promptly, accurately, and completely. A query is an opportunity; it signals that the reviewer has read the petition and identified a point requiring clarification. Slow or incomplete responses squander that opportunity.
Supplemental submissions are permitted where material new facts arise after the original petition. A corporate restructuring, the removal of a key associated person, or a settlement with another regulatory authority in the interval can all be grounds for a supplemental filing. In our experience, timely supplemental submissions on genuinely new facts can materially accelerate a review.
It is also worth considering whether to request a meeting with OFAC staff. OFAC has discretion to convene such meetings; they are not a matter of right. When granted, they allow counsel to present the case orally and to address specific concerns. Not every petition warrants a meeting request, and an ill-prepared meeting can be worse than none. The decision depends on the complexity of the matter and the state of the record.
If a transaction has already been flagged, or a filing has encountered difficulty, an early review of the post-submission strategy can preserve options that narrow with time. Write to info@caldervance.com to discuss.
How does OFAC compare with other regimes – and why does it matter?
An OFAC designation rarely exists in isolation. For a business or individual with international operations, a US designation typically triggers parallel reviews or designations under the UK, EU, or UN regimes. Each has its own petition or reconsideration process, and progress in one jurisdiction can – but does not automatically – support a parallel challenge in another.
Under OFSI (the UK's Office of Financial Sanctions Implementation), the review process is governed by the Sanctions and Anti-Money Laundering Act (SAMLA) and the relevant thematic regulations. OFSI can revoke or vary a designation on the basis that the criteria are no longer met or were not met at the time of designation. The UK process allows a formal reconsideration request and, beyond that, a judicial review of the designation decision before the High Court. Our colleagues advising on OFSI matters note that the evidentiary expectations overlap substantially with OFAC's – a well-built evidence package for one petition is a strong foundation for the other.
The EU route differs structurally. Designations are made by the Council, and the primary legal challenge mechanism is an annulment action before the EU General Court. The General Court applies a proportionality and sufficiency-of-evidence standard. The Council must be able to point to a sufficiently solid factual basis; where it cannot, the Court has annulled listings. That is a different legal standard from OFAC's administrative-reconsideration process, and it requires a different litigation strategy. Obtaining legal advice specific to the EU process is essential; success before OFAC does not guarantee success at the EU General Court, and vice versa.
The UN route is separate again. Where a designation arises from a Security Council resolution, the delisting route runs through the relevant sanctions committee. For ISIL and Al-Qaida listings, the Ombudsperson mechanism provides an independent review channel. For other Security Council lists, the Focal Point for de-listing provides a petition channel, but without the Ombudsperson's independent-review function. Neither route is fast; both demand high-quality evidence and political engagement by the petitioner's home state in appropriate cases.

What are the risk flags that indicate a petition will fail?
Not every petition should be filed. Understanding the risk flags that predict failure – or that identify the preconditions to a viable petition – is as important as understanding the process itself.
The highest-risk indicator is an ongoing relationship with the conduct or persons that triggered the designation. OFAC will not remove a designation while the basis for it continues to exist. Where a petitioner remains in a business or ownership relationship with a sanctioned person, or continues to deal in the same goods or services that generated the designation, the petition will not succeed regardless of its drafting quality. The relationship must end before the petition is filed, and the evidence of termination must be clear and complete.
The second major risk is inconsistency between the petition and information available from other sources – company registries, shipping databases, financial-intelligence records, or prior regulatory filings. OFAC has extensive investigative resources and access to information that a petitioner may not anticipate. Where the petition's account differs from the public or intelligence record, OFAC will notice. Inconsistencies that look minor to the petitioner can be fatal to credibility.
A related myth worth addressing directly: some petitioners believe that because they had no knowledge of the conduct that triggered designation – they were a passive investor, a minority shareholder, or an employee with no decision-making role – they are automatically entitled to removal. That is not how OFAC's criteria work. The criteria for many designations do not require that the designated party knew of or directed the offending conduct. Knowledge and intent are relevant to some programmes and to some criteria; they are not a universal defence. Counsel's role is to identify precisely which criteria apply and whether knowledge or intent is in fact a relevant variable in the specific case.
Finally, petitioners sometimes underestimate the importance of the compliance narrative. OFAC is not simply deciding whether the past conduct occurred; it is also assessing whether designation still serves the programme's objectives. A petitioner who can demonstrate genuine, verifiable, and sustained remediation – real organisational changes, not paper policies – gives OFAC a basis to conclude that removal is consistent with the programme's goals. That compliance narrative must be built before the petition, not invented in it.
When to involve sanctions counsel – and what to expect
The right time to involve counsel is as early as possible after designation. The decisions made in the first days – about what to say publicly, what to say to counterparties, whether to seek emergency licensing for critical transactions, and how to preserve the evidentiary record – have lasting consequences for the petition and for any parallel criminal or regulatory exposure.
A common error is to delay counsel engagement until "the facts are clearer." Facts rarely become clearer on their own; they are assembled through methodical investigation that counsel should direct. Waiting means losing access to documents, losing the ability to manage early disclosures, and losing time in a process where time already moves slowly.
What should a business or individual expect from competent sanctions counsel in a delisting matter? First, a frank assessment of the petition's realistic prospects, based on what is known and what can be gathered. Second, a structured investigation of the factual record. Third, a clearly argued, well-documented petition that addresses OFAC's criteria directly. Fourth, active management of the post-submission period – responses to queries, supplemental submissions where warranted, and coordination with parallel proceedings in other jurisdictions. Fifth, where the petition does not succeed on an initial review, advice on the next steps, including the viability of further administrative or legal routes.
We have acted for businesses and individuals across multiple sectors in OFAC delisting matters, from the initial assessment through submission and post-submission management. The matters differ; the discipline required does not.
