A payment firm in Singapore suspends a transfer because the beneficiary's name matches a designation on OFSI's consolidated list. The beneficiary is a UK citizen with no connection to the designated person beyond sharing a surname. The transaction is frozen. The client cannot access funds. Every day of delay has a cost – reputational, commercial, and personal. What are the rules for removing that freeze, and how quickly can it happen?
Mistaken-identity removals under OFSI occur where a person or entity is incorrectly matched against a designation – that is, where the designated person and the affected party are distinct individuals or organisations. OFSI, the Office of Financial Sanctions Implementation within His Majesty's Treasury, administers the process under the Sanctions and Anti-Money Laundering Act 2018 (SAMLA) and the relevant thematic financial-sanctions regulations. The procedure is distinct from a formal delisting challenge and can, in straightforward cases, be resolved more quickly – though the standard of evidence OFSI requires is not to be underestimated.
As of March 2026, OFSI administers one of the most active financial-sanctions enforcement regimes globally, and mistaken-identity cases arise with meaningful frequency given the volume of designations across the major thematic programmes. This briefing sets out who administers the process, what the legal basis is, how the procedure works, where it diverges from comparable mechanisms under OFAC and the EU, and when a business or individual should involve counsel.
What is a mistaken-identity removal under OFSI?
A mistaken-identity removal addresses the situation where an asset freeze or a transaction prohibition has been applied to a person who is not the designated individual or entity – a false positive arising from name similarity, shared identifying information, or a screening system's inability to distinguish between two people with similar profiles.
This is categorically different from a designation challenge. In a designation challenge, the affected person accepts that they are the named designated party but contests the legal and factual basis for the designation itself. In a mistaken-identity case, the affected party asserts that they are simply not the person named on the list. The distinction matters procedurally and evidentially.
The legal architecture sits under SAMLA and the relevant thematic regulations – for example, the regulations giving effect to the UK's financial-sanctions programmes covering specific geographic or sectoral designations. OFSI issues guidance on how it expects financial institutions and affected individuals to engage with the process. That guidance, while not itself legally binding in the way a statutory instrument is, shapes OFSI's decisional practice and therefore has real practical weight.
In our experience, the most common route into a mistaken-identity situation is not direct engagement with OFSI at all. It begins with a bank, a payment firm, or a correspondent institution freezing a transaction or refusing an instruction because its screening system has returned a match. The affected party then seeks clarification – and that is when the question of whether to engage OFSI directly, and how, becomes urgent.
Who administers mistaken-identity removals and what is the legal basis?
OFSI, a directorate of HM Treasury, administers financial-sanctions implementation in the United Kingdom, including the identification of cases where an asset freeze or transaction prohibition has been incorrectly applied. The legal basis for the financial-sanctions regime as a whole is SAMLA, supplemented by the secondary legislation that enacts each thematic or geographic programme.
SAMLA gives the Treasury power to impose financial sanctions and, by extension, to correct their application where that application is factually mistaken. OFSI's enforcement guidance and licensing guidance set out the procedural framework for engaging with the office. Where a designated person and a false-positive subject share characteristics, OFSI's role is to confirm whether, on the evidence before it, the affected party is the designated person named in the relevant regulation.
OFSI's guidance is publicly available and updated periodically. It distinguishes between licensing routes – under which a transaction that would otherwise be prohibited can be authorised – and identity-clarification routes, under which OFSI confirms that a given person is not the subject of the designation. The latter is the operative mechanism for mistaken-identity cases.
The relevant thematic regulations contain the actual designation – the name, identifying information, and legal description of the designated party. Identifying information typically includes date of birth, nationality, passport or identity-document numbers, and known addresses. The richer that listing information is, the easier it ordinarily is to establish a distinction. Where a listing is sparse – for example, a name and a general nationality – a mistaken-identity argument requires more detailed supporting evidence from the affected party.
The position above covers the standard case. Your facts – the specific programme, the completeness of the designation entry, the jurisdiction in which the freeze has been applied, and the assets involved – change the analysis materially.

How does the OFSI mistaken-identity procedure work in practice?
The OFSI process for resolving a mistaken-identity case begins with the affected party – or their counsel – compiling a factual dossier that demonstrates the distinction between themselves and the designated person.
That dossier ordinarily includes identity documents (passport, national identity card, driving licence), evidence of address and nationality, documentation of the affected party's professional or commercial history, and, where available, evidence that the designated person's own identifying information is materially different. Biometric information is not always available but can be decisive where the listing includes a photograph or physical description.
The affected party, or their legal representative, submits that evidence to OFSI with a clear written representation setting out why they are not the designated person. OFSI will review the submission and may request further information. There is no publicly stated fixed deadline for OFSI's response in these cases, though OFSI's general guidance signals an expectation of engagement within a defined period – verify the current position before relying on a specific timeframe.
In parallel, it is essential to engage with the financial institution that has applied the freeze or refused the instruction. Banks and payment firms are not agents of OFSI; they apply sanctions obligations as a matter of their own regulatory duty. Even if OFSI confirms that an affected party is not the designated person, the financial institution will need to see and act on that confirmation. In our practice, we regularly advise clients to run both tracks simultaneously – engaging OFSI and engaging the institution – rather than treating them as sequential steps.
Where OFSI's position is that the affected party has not been designated and is not the named individual, it can provide a written communication to that effect. That written position, shared with the relevant financial institution, ordinarily resolves the freeze. Where the institution remains uncertain – or where the institution's own compliance team is not persuaded – a specific licence from OFSI can operate as an alternative route, authorising the transaction even if there remains any residual ambiguity about the application of the designation.
The distinction between the identity-clarification route and the specific-licence route is not merely procedural. A specific licence – a case-by-case authorisation to conduct an otherwise prohibited transaction – does not constitute a determination that the affected party is not the designated person. It simply permits a defined transaction to proceed. Where the affected party's long-term relationship with financial institutions depends on a clear resolution of their identity, the licence route may not be sufficient on its own, and the identity-clarification route is the more appropriate mechanism.
How does the OFSI approach compare with OFAC and EU procedures?
The three major Western sanctions regimes – OFAC in the United States, OFSI in the United Kingdom, and the EU Council/General Court system in the European Union – each have mechanisms for addressing mistaken-identity situations, but they differ in structure, speed, and the role of the regulator in confirming an affected party's position.
Under OFAC, the equivalent mechanism is a request for a determination of non-applicability or an unblocking application. OFAC's process involves submitting evidence to the Office of Foreign Assets Control demonstrating that the blocking was applied to a party who is not the designated person. OFAC can issue a general licence or a specific licence, or it can issue a confirmation that the blocking was applied in error. The standard of evidence is comparable to OFSI's – detailed, documentary, and carefully structured.
A key difference is jurisdictional reach. OFAC's primary-sanctions prohibitions apply to US persons and to transactions involving the US financial system. Secondary-sanctions risk can reach non-US persons in certain circumstances, but the direct obligation to freeze assets under OFAC designations sits primarily with US persons and institutions. OFSI's obligations, by contrast, apply to all persons in the UK and to all UK-incorporated entities worldwide under SAMLA – a broad territorial scope that creates a different fact pattern for non-UK businesses encountering a false positive.
Under the EU regime, mistaken-identity situations are addressed either through engagement with the competent national authority of the relevant member state or, where the designation itself is in error, through an annulment action before the EU General Court. Where the issue is genuinely one of mistaken identity – the affected party is not the designated person – member-state competent authorities can provide clarification, and the General Court route is not typically required. The EU approach places greater structural weight on the competent authority of the member state where the assets are held, compared with the more centralised approach of OFSI.
For businesses operating across UK, EU, and US jurisdictions simultaneously, a mistaken-identity problem in one regime can cascade. A designation on the UN Consolidated List often drives domestic-regime implementations across all three systems. Resolving the UK position with OFSI does not automatically resolve the position under OFAC or under the applicable EU regulation. Coordinated multi-regime engagement, in our experience, is the only approach that fully protects the affected party.
If a transaction has already been flagged, or a filing has been refused under any of these regimes, an early review can preserve options that narrow with time. For a confidential discussion of multi-regime mistaken-identity exposure, write to Calder & Vance at info@caldervance.com.
What are the risk flags that indicate a mistaken-identity situation is more complex than it appears?
Several indicators signal that a case presented as a mistaken-identity situation will require deeper engagement rather than a straightforward clarification request.
The first is a sparse or incomplete designation entry. Where the designating authority – whether the UN Security Council, HM Treasury, or another – has listed a person with minimal identifying information, the burden of distinction falls more heavily on the affected party. There is less reference data in the designation to contrast against. The affected party must work harder to demonstrate the gap.
The second is where the affected party shares not just a name but some secondary characteristic with the designated person – the same approximate age, the same country of origin, or prior professional connections to a sector associated with the designation. These overlaps do not mean the affected party is the designated person, but they mean OFSI – and any financial institution reviewing the case – will scrutinise the evidence more closely.
The third is where the affected party has assets or transactional relationships in multiple jurisdictions. A resolution with OFSI covers the UK position. It does not bind a Singapore correspondent bank applying its own autonomous sanctions obligations, nor does it resolve the position under Australian DFAT, Canadian GAC, or Swiss SECO requirements where those also apply. Have you mapped every jurisdiction in which the mistaken-identity freeze has consequences?
The fourth is where a financial institution has taken a conservative position beyond what the designation strictly requires – sometimes described as de-risking (a financial institution exiting or restricting a relationship to avoid sanctions exposure). A de-risked institution may not re-engage even after OFSI provides clarification. That problem requires a different solution: one that addresses the institution's own compliance appetite rather than the sanctions designation itself.
The fifth is timing. If the affected party has obligations that become due – loan repayments, trade-finance settlements, payroll – while the freeze persists, the cost of delay compounds. OFSI's specific-licence mechanism can provide short-term relief while the identity-clarification process runs, but a licence application is itself a separate filing with its own preparation requirements. Starting that process late reduces the options available.
What does OFSI prohibit, and how does this apply in a mistaken-identity context?
OFSI enforces financial-sanctions prohibitions that, broadly, prevent persons from dealing with the funds or economic resources of a designated person, and from making funds or economic resources available to or for the benefit of a designated person. The prohibitions apply to all persons in the UK and to UK-incorporated entities acting abroad under SAMLA.
In a mistaken-identity context, the prohibition is not directed at the affected party – it is directed at those who hold or control the assets of the designated person. The practical effect is that the affected party's bank or payment firm, having identified an apparent match, treats the affected party's funds as if they were the designated person's funds and freezes them accordingly.
The affected party is not in breach of a prohibition. They are the victim of a misapplication of a prohibition. The financial institution that has frozen the funds is acting in good faith to comply with its own sanctions obligations. Neither party is at fault in the way that a genuine sanctions breach would imply. What is needed is a mechanism for correcting the factual error at the root of the misapplication.
That is the role of the OFSI identity-clarification process. Once OFSI confirms that the affected party is not the designated person, the financial institution's basis for maintaining the freeze falls away. The institution can release the funds or process the instruction without incurring liability under the financial-sanctions regulations.
It is worth understanding that OFSI's enforcement powers – including its power to impose a civil monetary penalty for a breach of financial-sanctions prohibitions – are not typically engaged in a genuine mistaken-identity case. The affected party has not breached a prohibition; they have been the subject of an erroneous application of one. The enforcement question arises separately, if at all, in relation to the institution's own compliance processes.
How is a mistaken-identity case enforced and what are the consequences of delay?
Enforcement, in the context of mistaken-identity removals, operates differently from enforcement of a positive sanctions obligation. OFSI does not typically bring enforcement action against a person whose identity has been incorrectly matched against a designation. The enforcement question is whether the financial institution that applied the freeze has done so correctly, and whether it acts promptly and appropriately once the identity error is established.
The Sanctions and Anti-Money Laundering Act and OFSI's enforcement guidance make clear that financial institutions are expected to have sound compliance processes – including processes for identifying and resolving false-positive matches. An institution that fails to resolve a false positive promptly after being presented with clear evidence of mistaken identity may itself face scrutiny of its compliance systems, even if the initial freeze was made in good faith.
For the affected party, the consequences of delay are predominantly practical rather than legal. A frozen account, a refused payment, or a suspended trade-finance facility can cause material commercial damage. The affected party cannot compel OFSI to act within a specified period in every case, but the quality and completeness of the evidence package submitted is the single most controllable factor in the speed of resolution. A well-prepared submission shortens the dialogue with OFSI and reduces the number of further-information requests.
We have acted for businesses and individuals where the delay between the first freeze and OFSI's written clarification was measured in weeks rather than months – precisely because the evidence package submitted at the outset was complete and clearly structured. We have also seen cases where repeated requests for supplementary information extended the timeline significantly. The difference almost always lies in the preparation of the initial submission.
One common myth in this area is that mistaken-identity cases resolve themselves once the affected party sends a simple explanatory letter to their bank. In practice, a letter to the bank – without engagement with OFSI and without a properly evidenced distinction from the designation – rarely resolves the problem. The bank cannot act on the affected party's assurance alone; it needs a confirmed position from OFSI or, at minimum, a specific licence. Underestimating the evidentiary requirement is the most frequent mistake we encounter.
