A London court needs to know whether a Ukrainian corporate resolution was validly adopted. A tribunal in The Hague requires expert evidence on a treaty obligation. A New York deal team cannot close without an opinion that a Ukrainian security interest will hold. Foreign law is a question of fact — and someone has to prove it.

Why this work is a separate discipline
The forum dictates the format
CPR Part 35 in London, the Federal Rules of Evidence in the US, IBA Rules in arbitration — an expert report is only as strong as its procedural compliance. We have worked to each standard, including before the PCA and the High Court.
Independence is the credential
A tribunal-appointed expert answers the tribunal’s questions, not a party’s brief. Our lawyers have been appointed by parties and by tribunals — the discipline is the same either way.
Doctrine plus courtroom
Doctoral degrees and Kluwer Law International publications matter to a tribunal; so does 25+ years in Ukrainian courts and arbitration. Expert evidence needs both — the citation and the practice behind it.
How we start
- Conflict checkSame day — for expert appointments we also confirm compliance with the forum’s procedural rules.
- Scope reviewLegal questions, assumptions, addressees and required format. 24–48 hours.
- Partner callYou speak with the expert who will sign the opinion — not an intermediary.
Common questions
What makes an expert acceptable to a foreign court?
Credentials and compliance: doctoral degrees, peer-reviewed publications, and a report that meets the forum’s procedural rules. Our experts hold doctorates from Taras Shevchenko National University of Kyiv and have published with Kluwer Law International.
Can you give evidence in English?
Yes — reports and testimony are delivered in English; certified translation is arranged where the forum requires formal submissions.
What is the difference between an expert report and a legal opinion?
An expert report is evidence inside proceedings — it helps the tribunal decide the case. A legal opinion is issued outside proceedings, usually for a closing, confirming defined legal conclusions. Different formats, same duty of independence.
How fast can an opinion be delivered?
Expert reports usually take two to four weeks; transaction opinions one to two. Court-imposed deadlines have been met within days.
Which areas of Ukrainian law do you cover most often?
Corporate resolutions and shareholder rights, contract enforceability and penalties, investment treaty protection, aircraft security interests under the Cape Town Convention, and recognition of foreign judgments and arbitral awards.
