PARIS ARBITRATION WEEK 2026: ADER HABER ON THE GLOBAL ARBITRATION STAGE
Our Of Counsel and Head of the International Desk, Iaroslav Gregirchak, FCIArb represented ADER HABER Law Firm at Paris Arbitration Week 2026, one of the leading international forums on arbitration and cross-border disputes.
Over the course of five days, Iaroslav participated in panels and specialized sessions covering ISDS reforms, new-generation BITs, arbitration dynamics in the Caucasus and Central Asia, as well as investments and post-war reconstruction in Ukraine.
The event provided a key platform for exchanging experiences with international practitioners, discussing real-world cases, and exploring strategic solutions in arbitration. It also reaffirmed ADER HABER’s active presence in the global arbitration community and highlighted the role of Ukrainian lawyers in international discussions on complex cross-border disputes.
What did PAW 2026 look like from the inside?
Iaroslav Gregirchak shares his personal impressions : "🎭 𝗣𝗮𝗿𝗶𝘀 𝗔𝗿𝗯𝗶𝘁𝗿𝗮𝘁𝗶𝗼𝗻 𝗪𝗲𝗲𝗸 𝟮𝟬𝟮𝟲 - 𝗠𝘆 𝗙𝗶𝗿𝘀𝘁 𝗖𝗮𝗿𝗻𝗮𝘃𝗮𝗹 🎆
A French colleague corrected during the 1st day: PAW is not a festival. It is a carnaval. After five days and fourteen events across the city, I understand exactly what she meant.
This was also my first time back in Paris since December 2015, when I completed the ICC Advanced International Commercial Arbitration Academy for Central and Eastern Europe. A decade. Long overdue.
I attended PAW on behalf of ADER HABER Law Firm, where I serve as Of Counsel and Head of the International Desk. My purpose was not only to be present in a room where disputes are discussed - but to make clear that when it comes to Ukraine recovery and reconstruction, ADER HABER offers something genuinely rare: a full-circle service capacity. Dispute resolution and international arbitration, yes. But also real estate and land, corporate and M&A, tax, competition, insolvency - and critically, the enforcement of international commercial arbitration awards on Ukrainian territory. The full picture, not a single frame.
The week itself was a masterclass in thematic and geographic density. I moved from a White & Case panel on preventing disputes before they arise, to a sharp ISDS reform debate at the Hôtel Plaza Athénée with Barton Legum, to an early-morning deep dive on new-generation BITs at the Maison de l'Amérique Latine. There were sessions on Caucasus and Central Asia arbitration dynamics, on infrastructure disputes and award enforcement, on ADR in construction and energy over cocktails at Le Meurice's Tuileries Room, on arbitration in the European defense industry at Freshfields, on sustainability - and, punctuating it all, multiple dedicated Ukraine reconstruction sessions. The K&L Gates / Ukrainian Arbitration Association (UAA) morning on investments into post-war reconstruction and contracts was particularly substantive, as was the Ukrainian Bar Association's enforcement panel at HKA Paris - aptly titled "𝘚𝘪𝘨𝘯𝘦𝘥, 𝘚𝘦𝘢𝘭𝘦𝘥, 𝘙𝘦𝘧𝘶𝘴𝘦𝘥: 𝘛𝘩𝘦 𝘌𝘯𝘧𝘰𝘳𝘤𝘦𝘮𝘦𝘯𝘵 𝘉𝘢𝘵𝘵𝘭𝘦𝘧𝘪𝘦𝘭𝘥".
Geographically, the conversations ranged from Singapore to Seoul, from the Gulf to the Caucasus, from Latin America to London. And Ukraine - inevitably, necessarily - was never far from the room's center of gravity.
I confess I took very few photographs. PAW moves fast and the conversations pull you in. But one proper set exists - from the Paris Bar's / Barreau de Paris / Ordre des avocats de Paris exclusive PAW 10th Anniversary gala at the Maison du Barreau, Paris est une fête! It turns out I shared the evening with Louis Degos, President of the Paris Bar, as maybe the only two guests in the house wearing bow ties . Some coincidences are worth documeting.
To everyone I met across those five days - panelists, practitioners, clients, fellow travelers in this peculiar carnaval - Thank You! The conversations have continued well beyond the Seine."
