Altelaw&Sempra is a leading Ukrainian law firm, best known for its market-leading practices in energy and construction and for a strong GR capability.

With more than 14 years in the market, the firm completed a strategic merger in September 2025, which broadened its practice areas and deepened the team’s expertise. Today, Altelaw&Sempra advises on the full commercial picture—from structuring complex energy projects to serving as trusted counsel on major reconstruction initiatives in Ukraine.

The firm’s offering is deliberately flexible: clients can engage us for targeted advice on a single issue or for end-to-end support across the entire lifecycle of a project.

Altelaw&Sempra’s partners sit on the Legal Committee of the Ukrainian Wind Energy Association and the Energy Law Board of the Ukrainian Bar Association, are members of the Confederation of Builders of Ukraine and the Union of Ukrainian Entrepreneurs, participate in the UN Global Compact, and are co-authors of Ukraine’s Anti-Corruption Strategy for 2026–2030.
