Expert witnesses for VIAC disputes — CEE perspective

Vienna has served as a bridge between Eastern and Western European commerce for decades — and VIAC reflects this positioning. Austrian law governs a significant share of CEE commercial transactions, and Vienna is the seat of choice for disputes involving Czech, Slovak, Hungarian, Polish and Romanian parties who want a neutral European forum without going to London or Paris.

Masin fields expert witnesses with direct Central and Eastern European project and commercial experience — construction, energy, M&A and financial disputes across the region.

Commercial and M&A

Business acquisition disputes, supply contract disagreements and commercial agency claims — the dominant VIAC sector.
