What is an expert witness service?

A Nextyn expert witness engagement sources, vets and manages qualified specialists who give independent expert opinion in a dispute. The service covers both roles: testifying experts, who produce reports and give evidence subject to cross-examination, and consulting experts, who advise counsel privately without appearing. Every candidate is independence checked against all parties to the matter before a name reaches the legal team, which is the step that protects the instruction later. Nextyn sources against the specific issues in the matter and the jurisdiction, then manages the engagement terms once counsel has selected an expert.

How much does an expert witness cost?

Nextyn agrees an expert witness’s rates and engagement terms with counsel before any instruction is made. Rates reflect the expert’s seniority, their field, and the demands of the matter, and report writing, deposition and testimony are rated separately. Nextyn sets out which rate applies to which activity in writing at the outset, so the cost of an instruction is known before it is given. Where a matter runs longer or wider than scoped, Nextyn re-confirms the terms in writing rather than continuing on assumption.

How do I find an expert witness?

Nextyn sources an expert witness from three inputs: the issues in dispute, the field, and the jurisdiction. 1. Brief. Counsel shares the issues, the field and the jurisdiction, plus every party to be independence checked. 2. Source and screen. Nextyn identifies candidates, verifies credentials, and independence checks each one against all named parties. 3. Shortlist. Nextyn puts forward vetted candidates with CVs and rates; counsel selects. The sifting sits with Nextyn rather than the legal team. Nextyn agrees the shortlist date with counsel against the directions timetable, so candidates arrive ahead of the deadline that governs them.

How does Nextyn confirm an expert is independent?

Nextyn independence-checks every expert witness against all named parties to the matter before a name reaches counsel. Screening covers three things: credentials, verified against the record rather than the CV; credibility, including prior testimony and any adverse judicial comment; and independence, covering current and former employment, financial interests, and prior instruction by any party. Checks run under the Nextyn compliance framework and are documented so the instruction can be defended if independence is challenged. Where a candidate has a prior connection that counsel may still accept, Nextyn discloses it rather than screening the candidate out silently.

Can you provide experts for international arbitration?

Yes. Nextyn sources expert witnesses for international arbitration across 70+ countries and every major seat. Arbitration instructions carry a test beyond litigation: whether the expert has given evidence before a tribunal rather than a court, and whether they can do so in the language of the proceedings. Nextyn confirms both before a name reaches counsel. Independence checks run against all parties, counsel and the tribunal where it is already constituted.

Definition

What is an expert witness?

An expert witness is a qualified specialist who gives an independent opinion to help a court or tribunal understand a technical, commercial or financial issue in a dispute. A testifying expert gives evidence and can be cross-examined. A consulting expert advises counsel behind the scenes without appearing. Nextyn provides both, sourced from a bench of practitioners that includes former regulators and former operators, and screened for relevance, credibility and independence.
