About us


OKW provides quality Polish legal advice with a Western approach to client service and can do so in Polish, English and Dutch.

The firm’s four partners Marta Olczak-Klimek, Maciej Węgiełek, Karolina Lach-Guziak and Remco van der Kroft provide a unique combination of Polish legal expertise and a Dutch no-nonsense client approach. We put our client’s business interests first and pride ourselves in always keeping the broader picture in mind.

The firm’s origins go back to 2004 when Marta started her firm, the same year that Remco came to Poland. OKW has since evolved into a firm with a staff of 26 people.

With three nationalities in the office and work experience in French, Polish, American, Dutch, German and Scandinavian law firms both in Poland and abroad, we are truly able to bridge the cultural gap and make foreign investors feel at home in Poland.

Because of OKW’s multinational background and international affiliations (Insuralex and DBLA), we are uniquely positioned to support Polish entrepreneurs in their exploits of the world’s markets.

Our support goes much further than just legal advice and litigation. As passionate sailors, we know the importance of teamwork. We try to understand our client’s business and use our contacts and knowledge of the Polish market and our extensive international contacts to help our client succeed, and thus become members of our client’s “crew”.
