This year's edition of the prestigious ranking "The Legal 500 Europe, Middle East & Africa 2024" published on March 27th, recommended the JLSW Law Firm as a specialist in construction law for the seventh time in the history of our firm.

This is a great recognition for the team, which, thanks to its knowledge and experience, provides irreplaceable support for our clients, business partners, contractors, engineering companies and architects in various investment projects.

Legal 500 - 2024:

"The construction practice at JLSW Janaszczyk Lis & Wspólnicy stands out as a key destination for contractors, engineering companies and architects seeking guidance on a range of investment projects, including residential, commercial, infrastructure, green energy and sustainable construction. Public procurement issues and contentious mandates are both strengths of the team, which often represents its clients in FIDIC-based contract disputes, as well as those relating to the extension of time, construction defects, and contractual penalties. Poznań-based Marcin Lis co-leads the group with Tomasz Janaszczyk in Warsaw. Olga Stiefel-Brzezinska is also an active team member."

Verified customer reviews as well as progressive solutions in residential, commercial, infrastructure, green energy and construction consulting have permanently associated our company with large-scale projects. We are effective in helping at every stage of our clients' projects!

We are also proud of our participation in key events: we reliably represent clients in contract disputes and in matters related to public procurement.

"What sets us apart? Undoubtedly: commitment, knowledge, experience and professional management of your affairs," says Tomasz Janaszczyk, JLSW Managing Partner.

Here is what clients told The Legal 500 about us:

‘I have known Tomasz Janaszczyk for almost 20 years – these are all years of professional cooperation, in which so many different events have happened, and each time the law firm has been able to select the right, competent and careful people focused on the goal, and on a pragmatic solution to the problem.’

‘When you cooperate with this legal practice you may be 100% sure that there are a lot of people among the legal team who can provide you with their individual knowledge and experience in different legal areas. You can outsource any legal case and you can be sure that it will be served by a specialist from a given field.’
