Altelaw & Sempra is a leading Ukrainian law firm, best known for its market-leading practices in energy and construction, and for a strong Government Relations 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.
We welcome new engagements and are ready to provide expert legal support to any client facing challenges — or simply seeking guidance — in energy, construction, or Government Relations. We don’t shy away from complex matters, even those that appear to have no clear solution. Our experience spans projects for leading industry players, as well as representing individuals in smaller cases that are no less important for the development of the rule of law in Ukraine.
The firm’s core practice areas are energy, construction, and GR. Building on these, the team has developed expertise across the Ukrainian and European energy markets, construction, logistics, agriculture, business defence, dispute resolution, and — in the context of energy projects — advertising and IT.
