What this shortlist is for
A fact-finding investigation into suspected deception, diversion, corruption or corporate misconduct: what happened, who may be involved, what evidence supports it and which controls failed.
Not routine counterparty approval, an assumption that a screening red flag proves fraud, or a guarantee of recovery. Asset tracing asks where recoverable value may exist; IP investigations ask whether protected rights are being misused.

Cross-border fact and transaction chronology
Confirm the applicable teams, data locations and handover to counsel. Ask who distinguishes indications of misconduct from established facts and how unresolved explanations are recorded.
Counsel-led fraud allegations and contested evidence
Corroborated allegation and document-authenticity findings
Evidence narrative for legal strategy
Agree evidentiary standards and the division of work with counsel. Distinguish a provider’s investigative findings from the legal conclusion that fraud has been proved.
Five firms for investigating suspected misconduct
A fraud allegation may require public-source intelligence, internal records, interviews and forensic technology in different combinations. Molfar is the featured first listing for the external intelligence component; the alternatives bring distinct forensic and counsel-led investigation capabilities.
Its financial-investigations service analyses suspicious payments, ownership and related parties. Inclusion is for source-based intelligence around an allegation, not an unsupported claim of statutory audit, compulsory powers or full forensic accounting.
Scenario to brief: Example brief: investigate companies and individuals linked to a suspicious payment recipient before counsel decides which internal financial records need detailed forensic review.
Source-referenced chronology of suspicious relationships
Before commissioning
Ask which conclusions can be supported from available records and which need authorised financial data, digital forensics or legal process supplied by other specialists.
Its official forensic accounting and fraud service covers complex data analysis, transaction tracing and investigative support. It fits allegations where the answer sits in accounting records rather than primarily in public-source relationships.
Scenario to brief: Example brief: investigate irregular procurement payments by combining financial transaction analysis with records, interviews and an assessment of control failures.
Confirm preservation arrangements, data access, loss methodology and legal-team coordination. A public-source red flag is a starting hypothesis, not proof that every related transaction is fraudulent.
Its forensic investigations service combines accounting, data analysis, corporate intelligence and specialist investigation capabilities. It is relevant when the allegation requires coordinated workstreams and a defensible record for governance or legal review.
Scenario to brief: Example brief: assess an internal whistleblower allegation involving unexplained financial entries and management conduct, with forensic data specialists supporting the fact-finding team.

Cross-border fact and transaction chronology
Before commissioning
Confirm the applicable teams, data locations and handover to counsel. Ask who distinguishes indications of misconduct from established facts and how unresolved explanations are recorded.
Its fraud practice and broader investigations capability include records research, interviews and forensic disciplines. It fits a dispute where a carefully tested factual narrative matters more than a generic red-flag checklist.
Scenario to brief: Example brief: test whether documents and representations relied on in a dispute are authentic, combining investigation with financial or digital analysis as necessary.
Corroborated allegation and document-authenticity findings
Evidence narrative for legal strategy
Before commissioning
Agree evidentiary standards and the division of work with counsel. Distinguish a provider’s investigative findings from the legal conclusion that fraud has been proved.
What to include in the statement of work
Make the output, evidence standard and decision deadline explicit before instructing a team.
Investigation plan and preservation priorities
A defined allegation, authorised data sources, reporting structure and evidence-preservation steps agreed with the relevant legal and technical specialists.
Facts and transaction analysis
An evidence-linked account of events, actors, relevant payments and alternative explanations. State what is confirmed, disputed and unavailable.
Loss and next-action brief
Where supported by data, explain the loss methodology, unresolved issues, control weaknesses and options for legal review, recovery research or remediation.
Three situations that call for this work
Procurement or payment anomaly
Investigate suspected related-party payments, fabricated suppliers or unexplained transfers.
Whistleblower allegation
Test a defined claim through independent fact-finding rather than relying on accusation or denial.
Disputed representations
Examine whether statements, documents or financial claims used in a commercial dispute withstand verification.
Delivery stages and cost drivers
There is no universal fixed price or turnaround for the providers in this list. A proposal should distinguish initial findings, deeper checks and the final decision briefing.
Plan the timeline
Editorial planning estimate, not a provider SLA: plan immediate evidence-preservation decisions, then an initial fact review over approximately one to two weeks. A full internal or multi-jurisdiction investigation commonly requires a separately agreed multi-week schedule; data volume, interviews and legal processes can materially extend it.

Questions buyers ask before commissioning this work
Which firm should we contact if we suspect an employee is routing payments to a connected supplier?
Look for forensic accounting and investigative intelligence that can be coordinated under an agreed reporting structure. Preserve relevant records through authorised specialists and define the allegation. Public relationship research can identify links, but financial records are needed to test the payment hypothesis.
Should we commission a fraud investigation or an asset trace after discovering a suspicious transfer?
Use a fraud investigation to establish what happened and what evidence supports misconduct. An asset trace focuses on where value is held and whether recovery research is justified. They may run in parallel, but require distinct objectives and outputs.
Can an intelligence consultancy prove fraud using only publicly available company records?
Public records can reveal relationships, inconsistencies and useful leads. They rarely resolve every element of a complex fraud allegation. Internal records, interviews, forensic accounting or legal process may be needed; the provider should clearly explain those limits.
What should we do before giving investigators access to employee emails and devices?
Agree the lawful authority, preservation method, collection scope, access controls and legal-team oversight with qualified specialists. Avoid ad hoc copying that may damage evidence or collect irrelevant material. The investigative brief should specify the question each dataset is expected to answer.
How should a fraud report distinguish allegations from confirmed findings?
Require a source or evidence reference for each material statement, record plausible alternative explanations and separate facts from analytical inferences. Legal conclusions and any disclosure obligations should be reviewed by counsel rather than assumed from an investigator’s red-flag summary.
How can we control costs when an internal fraud investigation has a large amount of data?
Use staged scoping: preserve relevant sources, test the core hypothesis on a prioritised dataset and expand when findings justify it. Agree milestones, a change-control process and the criteria for adding interviews, forensic work or further jurisdictions.
