Customers opinion

"I was not aware that the sale of a large business these days is such a complex matter. The letter of intent, the due diligence of the company, the negotiation of the agreement, the scope of my responsibility, the non-compete... Tons of stipulations, and behind many seemingly trivial words lies serious consequences. Thanks to the Dulewski Sikora law firm, I managed to safely go through the whole process and sell the company running a large factory. Attorneys Sikora and Dulewski supported me at every stage. They saved me from more than one trouble."

Martyna Paleczna and Stanisław Paleczny
former shareholders of Fanar S.A.

"Thanks to the Dulewski Sikora law firm, I gained a great deal of valuable information on what to look out for in share sale transactions. They gave me an awareness of certain things, the legal consequences that can be drawn through lack of knowledge or imprudent signing of documents that seemingly look like an initial non-committal proposal. We recommend the services of Dulewski Sikora to all those who are entering into share sale negotiations."
