FAQ

IMS’s custom expert witness team can quickly locate niche subject matter expertise, whether that be fluid dynamics, forensic linguistics, or even the rules of the International Skating Union. The custom sourcing process begins with a search far more sophisticated than keyword matching, enabling us to identify experts with domain precision.

  • Search: Our team, aided by proprietary AI technology, conducts a comprehensive search across our database and networks to uncover candidates whose expertise aligns with your specific case.

Complex litigation requires highly trained and specialized subject matter experts with expertise on niche issues, making early retention critical to allow sufficient time for sourcing, vetting, reviewing records, and expert preparation. IMS manages all aspects of this timeline, working retroactively from scheduling orders and disclosure deadlines to ensure your expert is fully ready for deposition and trial.


Engaging an expert witness during pre-suit investigation or early discovery enables counsel to evaluate liability, causation, and damages with subject-matter precision, refine case strategy by testing assumptions and identifying evidence gaps, and preserve flexibility for mediation, settlement, or trial testimony.
