About
I am a Polish advocate with over 15 years of experience in litigation, particularly in civil and commercial law.
I assist individuals and businesses. I assess each case individually, taking account of its circumstances, the client's interests and the available legal remedies.
I handle divorce, maintenance and child contact cases, as well as legal incapacitation proceedings. My practice also covers personal rights, press law and Swiss franc loan disputes. I draft and review contracts in Polish and English.
