GLG hosts CLE webinar on expert witness testimony with Above the Law

GLG is co-hosting a CLE-eligible webinar with Above the Law on January 22, 2026 at 1 p.m. ET, focused on expert witness testimony and cross-examination, according to Above the Law. The panel will cover what effective testimony looks like, examples from notable cases, how lawyers cross-examine experts, and trends in witness preparation including the role of technology.

The registration page frames the topic as a balancing act: experts must hold the respect of judge and jury while defending their own credibility under cross. CLE credit is available for live attendees.

What's actually being marketed

GLG's litigation and regulatory practice is the part of the business that sits next to, but operates differently from, the hedge fund expert-call seat most readers associate with the firm. Expert witnesses for trial are sourced, vetted, and prepared under rules set by the courts and Federal Rule of Evidence 702, not by buy-side compliance desks. The work product is a deposition or trial transcript, not a 60-minute call with a portfolio manager.

The webinar's stated agenda lists five topics: what "winning" testimony looks like, examples from notable cases, cross-examination technique, translating specialized jargon for factfinders, and trends in witness preparation including technology. The last item is the one worth watching. Witness prep has historically been a manual process: mock direct, mock cross, video review, repeat. AI-assisted tools that transcribe practice sessions, surface inconsistencies against prior testimony, and rehearse cross-examination scripts are now in the workflow at large litigation shops.

How this fits GLG's broader positioning

The webinar is co-branded with Above the Law, a publication whose readership skews toward associates and partners at large US law firms. That's the audience GLG's litigation business sells to. The hedge fund and corporate strategy desks that dominate the firm's public profile are not the buyers here. Litigation partners are.

The expert network category has spent the past two years competing on AI features for the investment-research use case: faster transcripts, better search across call libraries, summarization. The litigation seat is structurally different. Speed matters less. Defensibility matters more. An expert witness whose prior public statements contradict their trial testimony loses the case for the client. The technology that wins in this segment is the technology that prevents that, not the technology that summarizes a call in 90 seconds.

What the panel should answer

If the session is going to be useful to practicing litigators rather than a sourcing pitch, three questions need direct answers:

First, how does an expert network handle conflicts when an expert has consulted for both sides of a dispute, even years apart? The disclosure obligations under Daubert and the federal rules are stricter than what investment-research compliance handles, and the remedy when something surfaces mid-trial is not a refund.

Second, what's the actual role of AI in witness preparation right now, not in the marketing deck? Transcribing mock cross is one thing. Generating cross-examination questions from an opposing expert's prior publications is another. The panel will be more credible if it draws that line.

Third, how do experts translate specialized jargon for factfinders without crossing into the territory that opposing counsel will frame as "dumbing down" or "advocacy"? This is the craft question, and it's the one that distinguishes a witness who survives cross from one who doesn't.

The webinar runs January 22 at 1 p.m. ET. Registration is through Above the Law's events page.
