Comparison Table
Aon
enterprise_vendorProfessional services firm offering litigation risk and consulting services.
Risk and dispute analytics integrated with litigation evidence operations for damages and testimony-aligned support.
Aon’s litigation support engagements typically center on defensible collection workflows, evidence processing coordination, and production readiness workstreams that map to discovery protocol needs. Operational reporting and governance checkpoints help legal teams track progress from custodian intake through document review delivery, which reduces handoff ambiguity between legal, IT, and outside counsel. The engagement shape favors repeatable matter management tasks where roles and approvals must be auditable for litigation timelines.
A tradeoff is that Aon’s service orientation can require tighter pre-engagement scoping than purely self-serve e-discovery tooling, especially for defensibility expectations and production format constraints. A common usage situation is a multi-custodian dispute where internal counsel needs third-party custody discipline and review operations to keep meet-and-confer outputs and production sets aligned.
- +Matter governance checkpoints reduce evidence handoff risk across teams
- +Evidence intake and processing workflows align to protocol-driven production
- +Review operations support attorney-led workflows and privileging steps
- +Dispute analytics and expert-aligned support strengthen damages narratives
- –Requires early scoping of defensibility and production requirements
- –Service delivery can feel less self-directed than software-first tools
- –Advanced automation depends on engagement-specific configuration
- –Multi-system custody intake may extend timelines without IT readiness

Best for: Fits when complex, multi-custodian disputes need externally run evidence operations and governance controls.
Cornerstone Research
specialistEconomic and financial consulting firm providing litigation support.
Expert-driven damages and causation modeling that ties analytical assumptions to litigation evidence narratives.
Cornerstone Research is a fit for disputes where the business question drives the evidence requirements, because the engagement model supports case framing, data needs, and analysis handoffs. The firm’s work pattern typically pairs investigative collection planning with analytical outputs for damages, causation, and liability arguments. That pairing matters when e-discovery deliverables must map to model inputs and deposition themes rather than ending at a review queue.
A key tradeoff is that Cornerstone Research is not positioned as a self-serve managed review tool for high-volume document sorting, so control depends on engagement scope and internal legal operations capacity. It fits best when counsel needs expert-grade modeling plus evidence support for meet-and-confer positions and trial exhibit narratives.
- +Expert-led damages and liability analysis tied to evidence planning
- +Strong coordination across discovery strategy and courtroom-ready presentation support
- +Evidence handling governance that supports defendable workflows
- +Structured case workstreams with clear analysis deliverables
- –Less suitable for teams seeking purely software-run document review
- –Delivery speed depends on scoping clarity and expert availability
- –Integration depth with internal tooling depends on engagement design
- –Workflow configuration is not designed for rapid self-service changes

RGL Forensics
specialistForensic accounting firm providing litigation and insurance support.
Chain-of-custody documentation carried through collection to production support for litigation-grade defensibility.
RGL Forensics is built around defensible electronic data handling, with forensic collection practices and chain-of-custody tracking designed for court use. The engagement model fits disputes that require more than standard review workflows because it brings process control to how data is collected, processed, and produced. The provider’s focus on expert witness support also aligns with cases where technical findings must translate into courtroom narratives.
A tradeoff is that the work is more service- and process-driven than tooling-driven, which can reduce flexibility when teams expect self-serve e-discovery operations. RGL Forensics fits situations where meets-and-confer planning, custody documentation, and deposition preparation outputs must be coordinated across multiple custodians.
- +Forensic collection process discipline with chain-of-custody continuity
- +Expert witness support geared for courtroom-ready technical explanations
- +Production support that fits defensible, attorney-reviewed evidence workflows
- +Custodian interview inputs that improve collection targeting
- –Less self-serve than tool-first e-discovery teams expect

FTI-led litigation support that coordinates preservation decisions, collection scope, and courtroom exhibit readiness under a single delivery team.
FTI Consulting supports business litigation teams with consulting-led e-discovery, data collection, and expert-facing workflows built around dispute needs. The firm’s delivery model centers on defensible preservation, defensible collection, and litigation hold support tied to case strategy, not just document processing.
Engagements typically include ESI processing, privilege review coordination, and trial exhibit management for deposition and testimony readiness.

Charles River Associates
specialistConsulting firm providing economic and financial expertise for litigation.
Expert witness support that ties economic damages modeling directly to exhibits and deposition themes.
Charles River Associates supports business litigation by pairing economic and strategic advisory with structured litigation analytics that assist case teams through disputes and expert-driven workflows. The firm’s litigation services emphasize evidence valuation, damages modeling, and testimony support, which changes how document review outputs are translated into dispute positions.
Charles River Associates also coordinates technical workstreams with predictable deliverables such as reports, exhibit support, and deposition preparation so the litigation timeline stays anchored to analysis and documentation. For teams needing litigation support tied to economic questions, Charles River Associates’ emphasis on decision-grade outputs is a distinguishing constraint compared with vendors focused mainly on document processing.

Expert-led damage modeling paired with litigation testimony support that maps analyses to deposition and trial exhibit needs.
Navigant provides business litigation support through expert-led consulting for disputes that require quantified damages analysis, valuation, and financial forensics. The differentiator is its focus on litigation workstreams that hinge on documentary evidence and economic testimony, not general document review tooling.
The service coverage typically spans e-discovery coordination, matter-specific data collection workflows, and presentation support for depositions and trial exhibits.

How to Choose the Right business litigation support
Business litigation support covers evidence operations, expert-ready analytics, and courtroom-focused deliverables that stay aligned to dispute theories from preservation through deposition and trial exhibit preparation.
This guide covers Aon, Deloitte, and KPMG alongside nine other providers from the same litigation support shortlist, with Aon ranked highest for integrated dispute analytics linked to litigation evidence operations.
The selections also reflect how each provider handles governance checkpoints, chain-of-custody continuity, and the handoff between evidence work and testimony-aligned outputs.
Deloitte and KPMG appear in the guide because multi-party disputes often require delivery teams that coordinate evidence handling discipline with damages and causation narratives.
Business litigation support: dispute-aligned evidence operations plus testimony-ready analytics
Business litigation support pairs litigation evidence workflows with economic or damages analysis that can be translated into deposition and trial exhibit narratives.
Aon is designed for externally run evidence operations that integrate risk and dispute analytics with governance checkpoints that reduce evidence handoff risk across teams.
Cornerstone Research focuses on expert-driven damages and causation modeling that ties analytical assumptions to evidence narratives instead of emphasizing software-run document review.
Providers in this category commonly coordinate preservation decisions, evidence collection scope, and exhibit readiness to keep downstream testimony work consistent with upstream data handling decisions.
The buyer’s job is to match the dispute need, whether that is defensible forensic collection with chain-of-custody documentation or tightly scoped expert outputs aligned to courtroom themes, to the delivery model each provider uses.
Business litigation support capabilities that change dispute outcomes
Business litigation support must keep evidence handling discipline tied to what the dispute demands at deposition and trial exhibit stage. A provider that maps evidence operations outputs into testimony-ready materials reduces rework when theories shift after discovery.
The strongest differentiators show up in how a provider runs governance checkpoints across collection to production, how well damages and causation modeling connects assumptions to evidence narratives, and how chain-of-custody continuity supports defensible forensics. Aon is the benchmark for dispute analytics integrated with litigation evidence operations, while Cornerstone Research and RGL Forensics separate out expert modeling and defensible collection strength.
Dispute-aligned analytics tied to evidence operations
Aon integrates risk and dispute analytics with litigation evidence operations for damages and testimony-aligned support. Kroll provides discovery-to-trial coordination that connects forensic collection outcomes to deposition and trial exhibit preparation deliverables.
Expert-driven damages and causation modeling mapped to narrative evidence
Cornerstone Research delivers expert-driven damages and causation modeling that ties analytical assumptions to litigation evidence narratives. Navigant focuses on expert-led damage modeling paired with testimony support that maps analyses to deposition and trial exhibit needs.
Forensic defensibility with chain-of-custody continuity through production support
RGL Forensics emphasizes chain-of-custody documentation carried from collection through production support for litigation-grade defensibility. FTI Consulting coordinates preservation decisions, collection scope, and courtroom exhibit readiness under a single delivery team that supports defensible handling.
Economic harm quantification and workpapers designed for expert testimony
MDD Forensic Accountants provides case-centered economic harm quantification with structured workpapers for legal audiences. Analysis Group packages economic models into deposition and trial exhibit narratives tied to defined assumptions.
Governance checkpoints that reduce evidence handoff risk
Aon uses matter governance checkpoints to reduce evidence handoff risk across teams during protocol-driven production workflows. Kroll’s matter governance outputs reduce coordination gaps between legal and technical teams when disputes require end-to-end litigation support.
Exhibit and deposition preparation that stays aligned to upstream decisions
Deloitte and KPMG appear in the shortlist because multi-party disputes need delivery teams that coordinate evidence handling discipline with damages and causation narratives. Charles River Associates delivers expert witness support that ties economic damages modeling directly to exhibits and deposition themes.
How to choose business litigation support for evidence-to-testimony consistency
The selection process should start with where the dispute will fail if outputs lose traceability. A provider that optimizes for testimony narratives can be the wrong choice when governance gaps in collection to production create defensibility problems.
Then choose the delivery philosophy that matches case pressure points. Aon and Kroll lean toward externally run evidence operations with governance checkpoints, while Cornerstone Research and the other economics-led providers emphasize expert modeling that becomes the backbone for exhibits and deposition prep.
Map dispute risk to the handoff point that needs defensibility
If disputes hinge on defensible forensic collection outcomes and continuity to production, RGL Forensics is built around chain-of-custody documentation through collection to production support. If disputes hinge on downstream evidence-to-testimony translation, Kroll connects collection decisions to deposition and trial exhibit deliverables.
Choose whether the provider’s output engine should be evidence operations or expert modeling
If the evidence operations workflow drives damages and testimony alignment, Aon is designed for externally run evidence operations integrating dispute analytics with governance checkpoints. If expert modeling is the primary engine and evidence handling supports that narrative, Cornerstone Research ties analytical assumptions to evidence planning and courtroom-ready presentation support.
Run a workflow fit test for collection scope through courtroom readiness
If the case requires specialist-led defensible handling across preservation, collection, and trial exhibits, FTI Consulting coordinates preservation decisions, collection scope, and courtroom exhibit readiness under one delivery team. If the case requires defensible reporting artifacts, MDD Forensic Accountants delivers testimony-ready economic quantification and structured workpapers for attorney review.
Set expectations for automation and self-serve control depth
If operational control and governance checkpoints must run with less dependency on heavy vendor scheduling, Aon’s delivery emphasizes matter governance checkpoints across evidence intake and processing workflows. If the case can tolerate tighter scoping dependency on expert availability and delivery resourcing, Cornerstone Research’s delivery speed depends on scoping clarity and expert availability.
Decide whether the engagement needs expert outputs tightly packaged for deposition and trial
If deposition and trial exhibit narratives must stay aligned to defined assumptions and traceable analysis, Analysis Group’s expert-driven economic and damages modeling translates into testimony workflows. If the engagement needs deposition and trial exhibit readiness paired with damages analysis under a staffed expert-style approach, BDO USA supports courtroom defensibility with calculation trails.
Who benefits from business litigation support with dispute-aligned evidence operations
General counsel and litigation leaders benefit when business litigation support connects evidence handling discipline to testimony-ready outputs. The most value appears when disputes involve multiple custodians, complex damages theories, or forensic defensibility requirements that must survive cross-examination.
Finance and economic experts also benefit when providers deliver structured workpapers, exhibit support, and deposition preparation that map back to measurable assumptions. Aon fits when evidence operations governance needs to stay integrated with dispute analytics, while expert-led providers like Cornerstone Research, MDD Forensic Accountants, and Charles River Associates fit when expert modeling is the central deliverable.
Disputes with many custodians and externally executed evidence operations
Aon is designed for externally run evidence operations with matter governance checkpoints that reduce evidence handoff risk across teams for protocol-driven production.
Teams that need expert damages and causation narratives tied to courtroom presentation
Cornerstone Research provides expert-driven damages and causation modeling tied to evidence planning, and it coordinates expert analysis that supports courtroom-ready presentation.
Litigation that depends on defensible forensic collection and chain-of-custody continuity
RGL Forensics carries chain-of-custody documentation through collection to production support and adds expert witness support geared for courtroom-ready technical explanations.
Economic harm quantification engagements that require testimony-ready workpapers
MDD Forensic Accountants delivers case-centered economic harm quantification with structured workpapers that support attorney review and defensible reporting workflows.
Cases needing exhibit and deposition prep that stays aligned to upstream evidence handling decisions
Kroll ties collection decisions to downstream deposition and trial exhibit deliverables, and Charles River Associates ties economic damages modeling directly to exhibits and deposition themes.
Common mistakes in selecting business litigation support
The biggest failures come from choosing a provider based on deliverable branding rather than the governance and workflow alignment that controls defensibility. Another frequent failure is treating expert modeling and evidence operations as separable tracks that can be reconnected late in the schedule.
Avoid decisions that assume self-serve processing depth or API-driven automation when the delivery is staffing-led or scoping-dependent. Aon’s integrated dispute analytics and governance checkpoints reduce handoff risk, while providers like MDD Forensic Accountants and Analysis Group focus more on expert testimony workflows than high-volume e-discovery processing tooling.
Selecting based on expert credibility while ignoring evidence-to-testimony traceability
Cornerstone Research ties analytical assumptions to litigation evidence narratives, while Aon aligns dispute analytics with litigation evidence operations so governance decisions support the same story used in deposition and trial exhibits.
Assuming fast turnaround without scoping clarity for expert-led delivery
Cornerstone Research notes delivery speed depends on scoping clarity and expert availability, and Kroll’s turnaround depends on case complexity and resourcing allocation.
Choosing a forensics-first provider for end-to-end document review scale
RGL Forensics is optimized for defensible forensic handling and chain-of-custody continuity rather than tool-first self-serve operations, so document review scale should be assessed against the engagement plan.
Treating damages accounting as interchangeable with evidence operations
MDD Forensic Accountants focuses on testimony-ready economic quantification and workpapers and is not positioned for end-to-end e-discovery processing and document review at scale.
Overlooking governance discipline when coordination spans legal and technical teams
Aon’s matter governance checkpoints reduce evidence handoff risk across teams, and Kroll’s matter governance outputs reduce coordination gaps between legal and technical teams.
