Source-of-funds investigations in United States

A wire leaves a domestic account on a Tuesday. By Thursday, it has touched a correspondent bank, a pass-through shell in a low-disclosure state, and an account registered to a nominee director. The client calls on Friday convinced the trail is cold. In our experience, it rarely is – but the window to work it is already narrowing.

Source-of-funds investigations in the United States apply payment-trail reconstruction, forensic document analysis, and judicial disclosure tools to establish where money originated, how it moved, and where value ultimately settled. The primary instruments available include third-party disclosure orders, domestic freezing injunctions, and – in cross-border matters – the functional equivalent of a section 1782-type US discovery process compelling testimony and documents for use in foreign proceedings. Results depend on how quickly the investigation begins and how many institutional choke points remain reachable.

This analysis sets out how source-of-funds investigations actually work in the United States, where they succeed, where they stall, and what contrasting approaches practitioners take when the paper trail is deliberately broken. As of early 2026, the environment for financial disclosure litigation in the United States is more active than at any point in the previous decade.

What a Source-of-Funds Investigation Actually Establishes

A source-of-funds investigation answers three distinct questions: where money came from, how it was moved, and where it currently sits. These are not the same question, and conflating them is the single most common analytical mistake we see in referred matters.

The origin question traces funds back through layered accounts to a point of entry – the payor, the transaction date, the originating institution. The movement question maps how value crossed accounts, entities, and sometimes asset classes: cash to cryptocurrency, cryptocurrency to real property, real property to an offshore holding structure. The settlement question identifies where the economic benefit now rests and in whose hands – which is the question that ultimately drives enforcement.

A source-of-funds investigation is a forensic exercise, not a legal claim. The investigation product – a reconstructed payment trail, a chronology, a funds-flow diagram – becomes the evidentiary backbone for a civil claim, a regulatory referral, or a court application for disclosure or freezing relief. Producing that product requires access to records, analytical skill, and – critically – speed before document retention windows close.

In our experience, the United States is one of the most record-rich environments for this work. Correspondent banking infrastructure, domestic AML/KYC obligations, real-property transaction registries, corporate filings across state registers, and Securities and Exchange Commission reporting databases all produce documents that survive well beyond the underlying transaction. The challenge is access, not existence.

Why the United States Presents a Distinctive Tracing Environment

The United States is neither a pure civil-law nor a pure common-law jurisdiction in the English sense. Federal courts operate under procedural rules that are, in certain respects, more disclosure-generous than their counterparts in common-law hubs such as England and Wales or Singapore. In other respects – particularly for interim relief pending a final judgment – the environment is more constrained.

The breadth of US discovery in civil litigation is a genuine analytical advantage. Depositions, document requests, and interrogatories can reach deep into financial institutions and corporate structures. Where the target is a US entity or individual, or where records are held on US soil, civil discovery is a powerful tool for reconstructing a payment trail.

Cross-border practitioners face a different dynamic. The functional equivalent of what practitioners elsewhere call section 1782-type US discovery – a mechanism by which a foreign court or arbitral tribunal can obtain documentary and testimonial evidence from US-based persons and institutions – is one of the most significant tools available to claimants whose money has passed through the United States, even if the primary dispute sits offshore. The scope of that tool has been the subject of significant judicial debate, and practitioners coordinate closely with admitted local counsel in the United States; local procedure governs the filing and the outcome.

For asset tracing specifically, this creates a two-track system. A claimant with a domestic US claim accesses full civil discovery. A claimant with a foreign judgment or pending foreign proceeding accesses the US courts through a distinct, narrower procedural gateway. We regularly advise on which track is available and which produces usable intelligence faster.

How the Money Moves – and Where the Trail Breaks

Understanding the architecture of a payment trail is prerequisite to investigating one. In US-routed fraud, funds typically move through recognisable patterns – even when the movement is designed to obscure origin.

The first pattern is layering through domestic shell structures. Delaware, Wyoming, and New Mexico are the most commonly encountered low-disclosure formation states. Nominee directors or managers appear on public records; beneficial ownership information, where collected at all, sits with registered agents rather than public registries. A UBO register at federal level is now developing under recent anti-money-laundering legislation, but implementation and access remain partial as of early 2026.

The second pattern is offshore-to-domestic routing. Funds originating offshore are introduced into the US system through correspondent banks, real-property purchases, or securities accounts – often described by investigators as "placement" in the classic layering typology. Once inside the US financial system, the funds acquire a veneer of legitimacy that is particularly resistant to tracing unless the entry point can be identified.

The third pattern – increasingly encountered – is crypto-to-fiat conversion. On-chain tracing identifies wallet addresses, clustering, and exchange choke points. Public blockchains are transparent: on-chain movements are traceable even when identities are hidden behind pseudonymous addresses. The conversion point – where digital assets become fiat currency, typically through a virtualasset service provider (VASP) – is the critical chokepoint. A disclosure order against a VASP operating in or with nexus to the United States can compel identity disclosure and account information, giving the investigation its first reliable identity anchor.

The trail breaks most commonly at three points: the use of cash (genuinely untraceable without surveillance or third-party witness evidence); the movement of value offshore before any domestic proceeding is commenced; and the interposition of attorney-client or accountant-client privilege claims that delay or block document production. Each of these requires a different investigative response.

What Disclosure Tools Are Available – and When They Apply?

US courts offer several instruments relevant to source-of-funds investigations, and the choice between them depends on the stage of the dispute, the location of the target, and whether the primary proceeding is domestic or foreign.

In a domestic civil matter, a Bankers Trust order – or its US procedural analogue compelling a bank to disclose information about a customer's account – can be sought relatively early in proceedings. This produces account statements, transaction records, wire instructions, and correspondent-bank routing details that form the backbone of any funds-flow reconstruction. Third-party disclosure against a financial institution is standard practice in US civil litigation, though the process is more structured than its English counterpart and typically requires a pending domestic case.

A Norwich Pharmal-type order – compelling a third party to disclose information to identify an unknown wrongdoer – is less embedded in US federal practice than in English courts, but analogous relief is available in some states under state-law principles, particularly in fraud and conversion matters. We coordinate closely with admitted local counsel in the United States on the availability and form of such relief; local procedure governs the filing.

For foreign claimants, the section 1782-type US discovery mechanism is the primary instrument. It permits a foreign or international tribunal to obtain evidence from persons and entities in the United States. The evidentiary product – depositions, documents, financial records – can then be used in the foreign proceeding. The scope and availability of this tool vary by circuit, and the US Supreme Court has addressed its boundaries in recent years. Practitioners must assess, before investing in the process, whether the specific forum and specific evidence type fall within the available scope.

Interim freezing relief in the United States sits outside the clean English model. A domestic freezing injunction – an order restraining a defendant from dissipating assets pending judgment – is available but subject to a bond requirement and a more sceptical judicial culture around pre-judgment asset restraint. A proprietary injunction, asserting a trust or ownership claim over specific identified funds, is more readily granted because it does not restrain all assets – only those in which the claimant asserts a proprietary interest. Where funds can be traced into a specific account or asset, a proprietary injunction is often the more viable route.

Reconstructing a Trail from Incomplete Records – Is It Feasible?

The most common objection we encounter is this: the records have been destroyed, the accounts closed, and the trail is cold. This objection is almost always overstated.

Financial institutions in the United States are subject to bank-secrecy and AML record-retention obligations that extend across multiple years. Even where a customer has closed an account, the institution typically retains the underlying transaction records, wire instructions, and know-your-customer documentation for the legally required period. These records are not publicly accessible – but they are accessible through the appropriate court process.

A matter referred to us in the eastern United States in late 2024, involving funds in the mid-seven figures routed through a series of single-member LLCs before conversion into residential real estate, illustrates the point. The client believed the trail was lost because the originating account had been closed and the LLC had been dissolved. In practice, the correspondent-bank records, the real-property transfer documents, and the formation agent's KYC files all survived. The gap was bridged by open-source corporate registry searches, a real-property ownership analysis, and – critically – a targeted document request directed at the institution that handled the correspondent-bank leg of the wire. Reconstruction from partial records is feasible when institutional records survive – and in the United States, they typically do.

What cannot be reconstructed from records alone is the cash leg. Where funds are withdrawn as cash and physically moved, the documentary trail terminates at the point of withdrawal. This is rare in high-value commercial fraud – cash is inefficient at scale – but it does occur, particularly in retail fraud and in cases where funds are reduced to negotiable instruments before being reintroduced into the system.

Contrasting Positions – Where Practitioners Disagree

Source-of-funds investigation in the United States is not a settled field. There are genuine analytical disagreements among practitioners, and understanding them sharpens the strategy a claimant should adopt.

The first debate concerns sequencing: should a claimant pursue civil discovery first, or engage financial intelligence tools in parallel? The conservative position is to open discovery first – on the basis that judicially obtained records carry evidentiary weight that informal intelligence does not. The more aggressive position is that open-source intelligence, corporate registry analysis, and blockchain-analytics tools can identify the settlement point quickly enough to justify a simultaneous application for freezing relief before discovery is complete. We regularly advise on which sequencing suits the specific facts.

The second debate concerns the cross-border gateway. Practitioners disagree about when the section 1782-type US discovery mechanism is worth pursuing for a foreign claimant. The mechanism is time-consuming, requires US-admitted counsel, and produces evidence that must be authenticated for use abroad. Against that, it reaches records that cannot be obtained through any other process. For matters involving funds that passed through US correspondent banks – a frequent occurrence in international wire fraud – the mechanism often produces critical evidence unavailable elsewhere.

The third debate is structural: is the priority to follow the money to its current location (enforcement focus) or to establish origin beyond reasonable doubt (litigation focus)? These produce different investigation architectures. An enforcement-focused investigation maps the current asset picture and applies for freezing relief early. A litigation-focused investigation builds the strongest possible chain of causation from fraud to dissipation to current holder. In our experience, the most effective approach combines both – but resources and timing determine how far each track can be pursued in parallel.

A further point of disagreement concerns the use of blockchain-analytics tools in non-crypto matters. As fraud proceeds increasingly touch digital assets – even briefly, as an intermediate step – on-chain analysis has become relevant to investigations that are ultimately about fiat-currency losses. Some practitioners treat blockchain analytics as peripheral unless the asset is directly a digital asset. We treat it as standard practice in any matter where there is evidence of conversion to or from digital assets at any point in the trail.

Cross-Border Complications – When the Money Moves Out of the United States

A frequent pattern in US-based fraud is partial domestic movement followed by offshore transfer. The money passes through US accounts – acquiring a transactional record – before being wired to a jurisdiction with lower disclosure standards or a weaker civil-recovery infrastructure.

This creates a multi-forum problem. The US leg of the transaction is documentable through civil discovery or the section 1782-type mechanism. The offshore leg requires local counsel in the relevant jurisdiction, a separate disclosure application, and – if freezing relief is sought – a parallel proceeding in the receiving jurisdiction's courts. A worldwide freezing order, as recognised in common-law jurisdictions, can in principle reach assets outside the forum; but the United States does not grant worldwide freezing orders in the English sense, and the territorial reach of US pre-judgment attachment orders is generally limited.

For a claimant whose funds have moved from the United States to a foreign jurisdiction, the practical strategy is usually to obtain the US documentary record first – establishing the payment trail and the receiving account – and then use that record to anchor proceedings in the receiving jurisdiction. The US evidence establishes provenance; the foreign proceeding provides the enforcement mechanism. We have traced funds through this two-stage process in matters involving European, Middle Eastern, and Asian receiving jurisdictions, always working with local counsel where the freezing application must be filed.

For inbound matters – where funds originate offshore and enter the United States – the question is whether the domestic US assets can be frozen or attached pending resolution of the foreign dispute. This depends on the nature of the US assets, whether the foreign judgment is enforceable in the United States under applicable recognition-and-enforcement principles, and whether a proprietary interest in the specific US assets can be asserted. The New York Convention provides for recognition and enforcement of foreign arbitral awards across most states, including the United States – making arbitral awards a frequently used enforcement vehicle for claimants with US-sited assets to reach.

Practical Steps – What Happens in the First Forty-Eight Hours

Speed matters. A source-of-funds investigation that begins promptly has access to records, accounts, and counterparties that may be unavailable days or weeks later. Accounts can be closed, entities can be dissolved, and assets can be transferred offshore with little warning.

The first step is evidence preservation. Every document in the client's possession that relates to the transaction – wire instructions, contracts, communications, account statements – must be captured and organised before anything else. Secondary documents are almost as important: corporate records of any entity involved, property records, and any public-registry information about counterparties.

The second step is a rapid open-source assessment. Corporate registry searches across relevant states, real-property ownership records, UBO filings where available, and public court records often identify the nominal recipient of funds and their associated structures within hours. This does not establish beneficial ownership – but it identifies the inquiry targets and the most productive avenues for formal disclosure.

The third step is engaging US-admitted counsel for the formal process. Source-of-funds investigations in the United States require proceedings – either a civil action to generate discovery rights, or a section 1782-type application for foreign claimants. We coordinate closely with admitted local counsel in the United States on the filing strategy; local procedure governs every step of the formal process.

The fourth step – which should run in parallel with step three, not after it – is a funds-flow model. Even with incomplete records, the available information supports a preliminary model of how funds moved. That model identifies the gaps; the gaps identify what disclosure is needed; the disclosure application targets exactly those gaps.

A Common Misconception – and What to Do Instead

The most persistent myth in source-of-funds investigation is that an incomplete paper trail means the investigation is futile. This belief leads clients and their advisers to delay – sometimes fatally – before engaging a specialist. It also creates vulnerability to a second danger: recovery scams.

Recovery scams exploit exactly this moment of despair. A victim is told their money is irrecoverable through legitimate means – and then offered an informal "recovery" service that promises results no legitimate investigation can guarantee, typically in exchange for an upfront fee. Legitimate source-of-funds investigation involves no upfront guarantee of recovery, no promise of a specific outcome, and no pressure to act before the client has taken independent advice. If a service promises you a percentage or a guaranteed outcome, it is not a source-of-funds investigation – it is a second fraud.

The honest position is this: a trail that looks dead from the outside is often alive in institutional records. What is actually required is not a miracle – it is access to those records through the appropriate legal process, applied quickly enough to matter. Whether that process is worth initiating depends on the specific facts, the current location of assets, and a realistic assessment of costs against likely recovery. Those are the questions a genuine case review answers.

We reconstruct payment trails from partial records and identify where value settled. That is the work – and it requires the right tools, admitted local counsel in the United States, and a clear-eyed view of what is and is not achievable in each forum.

Frequently Asked Questions

Q: Can a money trail be reconstructed from incomplete records?

A: In most cases, yes. Financial institutions operating in the United States retain transaction records, wire instructions, and know-your-customer files for periods set by bank-secrecy and anti-money-laundering obligations. Even after an account is closed or an entity dissolved, those underlying records commonly survive and are reachable through civil discovery or, for foreign claimants, through the section 1782-type US discovery mechanism. Open-source corporate registry and real-property data also fill gaps that internal records cannot. The genuine limits are the cash leg – where funds leave the institutional system – and the offshore transfer that occurs before any domestic proceeding is opened.

Q: How do you trace funds routed through the United States?

A: We begin with an open-source assessment of the nominal recipients – corporate registries across relevant US states, real-property ownership records, and any available beneficial-ownership filings. That identifies inquiry targets quickly. The formal layer then follows: a domestic civil action generates full discovery rights against financial institutions and corporate entities; a section 1782-type application gives foreign claimants access to the same records for use in foreign proceedings. Where digital assets were involved at any point in the chain, on-chain analysis runs in parallel, focusing on exchange choke points and virtualasset service provider (VASP) disclosure. All formal filings are handled by admitted local counsel in the United States.

Q: What information do you need from me to start tracing?

A: The most useful starting material is whatever documentary record exists of the transaction: wire instructions, contracts, account statements, email correspondence, and any company information about the counterparty. We can begin with very little – even a recipient account number and the approximate transaction date is a usable starting point. What we assess at the outset is the quality of the existing evidence, the jurisdictions involved, the approximate value, and the time elapsed since the transfer. Those four factors determine which tools apply, how quickly they can be deployed, and whether the economics of a full investigation are justified.
