Frequently Asked Questions

What qualifications should an e-discovery expert witness have?

An e-discovery expert should hold a relevant credential such as CEDS, have extensive experience managing large-scale electronic discovery, demonstrate proficiency with industry-standard platforms, and understand the legal framework including the Federal Rules of Civil Procedure governing ESI. Both technical and legal knowledge are required.

What types of cases require an e-discovery expert?

E-discovery experts are needed when parties dispute preservation obligations, collection methodology, the scope and proportionality of discovery requests, search term adequacy, technology-assisted review reliability, or production format. They are also retained to manage complex e-discovery projects and advise on best practices.

How much does an e-discovery expert witness cost?

In general, technology expert fees are determined by the expert themselves, based on a variety of criteria. Among those criteria are professional experience, forensic experience, technical certifications, industry specialization, and publications. Vident does have some influence over expert fees by comparing experts within a specialty, but ultimately it is a personal decision by the expert.
