Expert Witness Services
Counsel retain Grahall in four ways, depending on where the matter stands and what the case requires. Each engagement rests on the same foundation: independent analysis, documented methodology, and opinions supported by the available evidence. Our methodology overview explains how the underlying analysis is built.
Testifying Expert
We provide independent analysis and an expert report for the applicable forum, with deposition, trial or arbitration testimony when included in the agreed engagement. The analysis documents the evidence, assumptions and basis for each conclusion.
Consulting Expert (Non-Testifying)
We provide independent non-testifying compensation analysis to help counsel evaluate the question and prepare the matter. Counsel determines the appropriate engagement scope and applicable disclosure requirements.
Rebuttal Expert
We assess an opposing expert’s report, data sources and methodology, identify supported conclusions, and explain material limitations or disagreements. Rebuttal reports and testimony are separately scoped to the needs of the matter.
Early Case Assessment
Before you commit to a litigation posture, we provide a preliminary read on the compensation question: whether the number is defensible, what the evidence is likely to support, and what a full analysis would involve.
