Wire Transfer Fraud | Ross Mallioux Banking Expert
Wire Transfer Fraud and Funds Transfer Disputes
Wire transfer fraud disputes often raise practical questions about how a payment instruction was received, verified, approved, and processed. They may also involve questions about the agreements, procedures, systems, and controls the financial institution had in place at the time of the transfer.
Attorneys handling these matters may need help understanding what happened operationally, what information was available to the institution, what procedures applied, and whether those procedures were followed.
Every matter is different. The areas discussed below are examples of issues that may be relevant in a wire transfer case. They are not intended to be a checklist for every engagement. The scope of my analysis depends on the facts of the case, the issues presented, and the records available for review.
My analysis is often grounded in the examination and risk-management frameworks used within the banking industry — including the FFIEC IT Examination Handbook, interagency guidance, and standard treasury-management and payments-operations practice — applied to the specific facts, documents, and transaction records available in each matter.
Business Email Compromise and Payment Diversion Schemes
Many wire transfer disputes involve payment instructions that were altered, fabricated, or redirected after an email account or communication channel was compromised.
These schemes may involve changed vendor instructions, fabricated executive requests, intercepted transaction communications, altered payoff instructions, or substituted real estate closing instructions.
Depending on the facts, my review may consider how the payment instruction reached the institution, what information was available to bank personnel, what verification steps were performed, and whether the request was consistent with prior account activity, established instructions, or the customer’s normal transaction history.
Funds Transfer Agreements and Security Procedures
Wire transfer cases often involve the security procedures in place between the financial institution and its customer.
My review may include funds transfer agreements, treasury management documents, available security options, customer elections or documented declinations, token and credential administration, transaction limits, approval requirements, and records showing how the procedures were actually administered.
My focus is on how the procedures were designed, how they compare to practices in general use by similarly situated institutions and customers, and whether they were followed in the transaction at issue. I do not offer an opinion on whether a procedure was "commercially reasonable" or otherwise satisfies an applicable legal standard — that determination is for the court or trier of fact.
Payment Verification and Callback Procedures
Verification procedures can be an important part of a wire transfer dispute.
Depending on the case, I may review callback requirements, the source of the telephone number used for verification, out-of-band confirmation, dual control, separation of duties, approval authority, and exception handling.
The review may also include the policies and procedures in effect at the time, training and operational materials, and records showing what steps were performed, by whom, and how those steps were documented.
Real Estate Closing and Escrow Wire Fraud
Real estate transactions are frequent targets for wire fraud because the timing, parties, and approximate amount of the transfer may be known to several people.
These cases may involve diverted buyer funds, redirected sale proceeds, altered payoff instructions, or substituted disbursement information.
My review may include closing instructions, wire request documents, account agreements, transaction records, communications retained by the institution, and the procedures used by the originating or receiving institution in processing the transfer.
Beneficiary Bank Practices and Receiving Account Activity
Some disputes involve the institution that received the funds rather than, or in addition to, the institution that sent them.
Where relevant, I may review account opening and customer identification records, the age and prior activity of the receiving account, the expected purpose of the account, the transaction activity visible to the institution, and the institution’s internal review and escalation procedures.
I may also consider how beneficiary name and account number information was received, displayed, processed, or used within the applicable payment system and the institution’s procedures.
My analysis is limited to banking operations and practices. I do not offer legal opinions regarding the existence or scope of a duty, statutory liability, or the institution’s ultimate responsibility for the loss.
Transaction Monitoring, Red Flags, and Escalation
A wire transfer dispute may involve allegations that indicators of suspicious or unusual activity were present and were not acted upon.
Depending on the facts, my review may include transaction monitoring systems, alert parameters, alert disposition records, internal communications, escalation procedures, and coordination among branch, operations, fraud, risk management, and other personnel.
The practical question is often whether the institution’s established procedures identified the activity, whether the activity was reviewed, and whether the matter was escalated and documented as the institution’s procedures contemplated.
Where applicable, I may consider regulatory and interagency guidance in effect at the time as evidence of the practices and expectations in general use in the banking industry during the relevant period. Such guidance must be considered in light of its purpose, scope, applicability, and effective date. I do not offer an opinion that such guidance, by itself, creates a legal duty, establishes the applicable legal standard, or determines liability.
Response, Recall Requests, and Post-Transfer Actions
The actions taken after a fraudulent transfer is discovered may also be important.
My review may include the timing and content of the customer’s notice, the institution’s internal response procedures, escalation to fraud or operations personnel, recall or return requests sent through the applicable payment channel, communications with other financial institutions, and coordination with law enforcement reporting mechanisms.
The analysis may consider the timing of the response, the information available to the institution at each stage, and whether the documented actions were consistent with the institution’s applicable procedures.
Consumer, Commercial, and Vulnerable Accountholder Considerations
The account type, payment channel, customer relationship, and transaction circumstances may affect the procedures and documents that are relevant to the analysis.
Matters involving older or potentially vulnerable accountholders may also raise questions about customer contact, branch observations, transaction interruption practices, internal escalation, and referral to fraud, risk management, or protective services personnel.
My analysis in these matters remains focused on banking operations and institutional practices. Legal determinations regarding capacity, exploitation, statutory duties, or liability remain outside the scope of my opinion.
My Approach to Wire Transfer Fraud Matters
My analysis begins with the facts and the documentary record.
Depending on the assignment, I may review the account type, payment channel, chronology, agreements, policies, procedures, transaction records, internal communications, customer communications, and relevant regulatory or interagency materials in effect at the time.
I then evaluate what the institution’s procedures required, what information was available, what actions were documented, whether established procedures were followed, and whether there were gaps, exceptions, or breakdowns in the process.
I also consider contrary information, reasonable alternative explanations, missing documents, and any limitations in the available record.

This is general information and not intended as any opinion on any relevant matter. My opinions are based on the facts and materials presented in the particular matter. They are directed to banking practices, funds transfer operations, and institutional conduct rather than legal conclusions, statutory interpretation, witness credibility, intent, or ultimate liability.
Digital forensics, email header analysis, network intrusion, cybersecurity engineering, and tracing funds through downstream accounts are outside the scope of my banking practice and are more appropriately addressed by specialists in those fields.
