GLG’s Expert Witness Services

GLG is the world’s largest expert witness network with approximately 1 million professionals across virtually every sector. Every engagement begins with a discussion of your specific expert needs with our dedicated team. There is no fee for starting an expert witness search with GLG.


Your GLG Research Manager consults our expert witness directory of approximately 1 million Network Members to identify the best fit for your case. If we don’t already work with the ideal expert, we’ll identify and recruit the right person.


GLG sends you the bio, CV, and detailed responses to screening questions for each expert witness we propose. We arrange complimentary screening calls with all proposed experts to validate their expertise.


Once we have found the right expert witness, GLG handles all billing. You receive one monthly bill. Our experts’ hourly rates include GLG’s facilitation fees; there are no additional costs.
