Infrastructure & Projects

As a sponsor, lender or public sector organisation, you require legal advisors who can help you succeed in complex infrastructure and project financing transactions. Whether you are involved in public works programmes or private sector financing in the transport, health, education, waste, energy, automotive and petrochemical industries, defence, IT/telecoms, leisure, custodial & justice, ports, rail, roads or water, you can depend on the leading lawyers in major infrastructure projects and related project financing throughout the world.

In Central and Eastern Europe, CMS has invaluable experience of the successful procurement and implementation of infrastructure projects, including providing key advice on procurement, project documents and financing strategy.

We have delivered deals in a range of sectors with a combined value of many billions of euros, advising on public private partnerships, energy and renewables projects, including the largest offshore wind farms in Europe, infrastructure and utilities investments and a range of other development and corporate finance transactions. If you are an investor selling or buying an interest in a concession, a utility business or a PPP deal, you need expert guidance through the complex bidding process. Our lawyers have helped shape transactions across these sectors, ensuring quick deal completions on terms that optimise your returns.

If you are facing a potential dispute, we have the experts to support you through dispute resolution procedures or litigation action. Whatever your situation, we have the track record and the people to help. We can support your transaction in virtually any part of the world including Hungary,  the UK, Central and Eastern Europe, Western Europe, the Middle East, Turkiye, India, Africa, Asia and the Americas.
