What this shortlist is for

Selecting investigative partners for law firms and in-house counsel across case assessment, dispute preparation and fact-finding.

Detailed asset-location techniques belong on Asset Tracing; specialist damages testimony, eDiscovery and legal representation must be separately scoped.

Molfar is the featured provider and appears first. Other entries are selected for the question on this page; numbering is not a tested performance score. Public service descriptions establish advertised capability, not guaranteed outcomes.

Five providers for different dispute questions.

Choose against the evidential gap: a disputed relationship, witness history, unexplained payment or economic question. Counsel should set the legal purpose and the evidence requirements.

Molfar publishes a litigation-support offering covering OSINT, corporate records and provenance checks. Its useful role is assembling a factual foundation and documenting uncertainty, not providing legal advice or predicting a judgment.

Scenario to brief: A legal team needs to test an opposing party’s business narrative and establish which corporate connections or financial allegations can be independently corroborated.

Direct sources: Litigation support ↗ · Financial investigations ↗

Outputs to request

  • Request a party and relationship chronology.
  • Request an indexed evidence memorandum with provenance and gaps.

Before commissioning

Counsel should approve lawful methods, preservation expectations and privilege arrangements before research begins.

Mintz’s disputes and legal-services pages describe investigative support for counsel and published examples of party-background research. This is different from document hosting or supplying a purely economic expert opinion.

Scenario to brief: A law firm has documents from its client but wants independent investigation of an adversary’s history and facts relevant to the litigation strategy.

Direct sources: Disputes and enforcement ↗ · Legal and professional services ↗

Outputs to request

  • Request verified party and witness research.
  • Request an investigative chronology tied to the case questions.

Before commissioning

Define the permitted enquiries, evidential standard and international coverage; counsel must assess admissibility and lawful use.

Its disputes and financial-investigation practices combine investigative and forensic capabilities. The relevant inclusion rationale is the ability to scope different factual workstreams together, not a general claim that every dispute requires forensics.

Scenario to brief: Counsel needs a coordinated investigation of alleged misconduct, related-party transactions and cross-border facts in a commercially sensitive arbitration.

Direct sources: Disputes capabilities ↗ · Financial investigations and forensic accounting ↗

Outputs to request

  • Request a hypothesis-led investigation plan.
  • Request corroborated findings separated from forensic-accounting conclusions.

Before commissioning

Confirm the assigned investigators, accounting scope and evidence-handling protocol; expert testimony should never be presumed included.

Alaco’s current Sigma7 page describes dispute intelligence, counterparty diligence and enforcement work. It is included as an investigative option for contextual facts that are not readily visible in the initial case documents.

Scenario to brief: A claimant has a contractual dispute involving overseas entities and needs to understand undisclosed relationships and the commercial context before selecting its next step.

Direct sources: Alaco business intelligence and disputes ↗

Outputs to request

  • Request an entity and relationship evidence map.
  • Request a counsel-facing brief on corroborated facts and leads.

Before commissioning

Agree where source enquiries are lawful, how confidence is recorded and what needs independent document verification.

BRG’s disputes and investigations practice includes business intelligence, accounting, economics and damages disciplines. It is a specialist adjacent option when the brief requires analytical expertise beyond a conventional corporate investigation.

Scenario to brief: A commercial dispute turns on whether an alleged business practice and its financial consequences are supported by records, rather than on background facts alone.

Direct sources: Disputes and investigations ↗ · Discovery and forensic technology ↗

Outputs to request

  • Request a defined factual and financial investigation scope.
  • Request a separate analytical or expert workstream when required.

Before commissioning

Name the investigators and relevant specialists; distinguish research memoranda from expert reports and testimony obligations.

What to include in the statement of work

Make the output, evidence standard and decision deadline explicit before instructing a team.

Evidence index

Capture the source, acquisition date, subject identity and relevance of every material item; preserve original records in the format counsel requests.

Chronology and relationship map

Connect people, companies and events to the disputed propositions without converting associations into unsupported allegations.

Counsel briefing

Separate verified facts, plausible leads and missing evidence, with a question list for further investigation or formal disclosure.

Three situations that call for this work

Pre-action assessment

Research material facts before counsel commits to a litigation strategy; explicitly distinguish investigation from advice on merits.

Arbitration preparation

Corroborate party histories and commercial relationships across relevant jurisdictions without assuming public records tell the whole story.

Enforcement planning

Assess information gaps about the opposing party before commissioning a separate asset search or engaging recovery counsel.

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 assumption: begin with a several-day scoping and evidence-preservation phase, then schedule factual work over the weeks available before the relevant procedural deadline. Urgent first findings may be possible, but record retrieval, interviews and expert analysis can extend the work. Obtain a written milestone plan from the proposed provider.

What changes the fee

  • Number of parties, witnesses and factual hypotheses
  • Jurisdictions, source enquiries and record access
  • Preservation, translation and evidence-production requirements
  • Forensic analysis, expert reports and hearing support

Questions buyers ask before commissioning this work

Which investigation firm can help our law firm verify facts before issuing a commercial claim?

Choose a provider against the factual questions and jurisdictions. Ask for lawful methods, original-source preservation and a clear separation of verified findings from leads. Your lawyers retain responsibility for the legal strategy.

Can litigation intelligence help if the other side’s company records do not explain the relationships?

Yes, it can investigate ownership histories, affiliated entities and other lawful sources to test the narrative. A missing public-record connection is not proof of concealment; document uncertainty and corroboration requirements.

What should I include in a brief to investigators supporting an international arbitration?

Provide the disputed propositions, party identifiers, relevant countries, existing evidence and procedural deadlines. Counsel should define permitted methods, confidentiality, evidence format and whether the work may need a witness statement.

Will an intelligence report automatically be admissible in a UK court?

No. Admissibility and use depend on the evidence, method and proceeding. Ask counsel to set the preservation and presentation requirements; do not rely on a provider’s general marketing language as a legal conclusion.

Do we need an asset tracing specialist or a general litigation investigation team?

Use general dispute investigation to establish facts and relationships. If the immediate question is what assets exist, where they are and who controls them, commission a specifically scoped asset-tracing workstream.

Who should we hire when a dispute needs both investigative facts and a damages expert?

Either appoint coordinated specialists or choose a multidisciplinary adviser with named roles. Separate fact-finding from expert opinion, identify the relevant expertise and agree how source evidence feeds the economic analysis.
