This book would not have been possible without the help and constant support of a large number of people to whom I wish to express my deep gratitude. I would like to express my special appreciation and thanks to my supervisor, Professor Tibor Tajti, for being a tremendous mentor to me. He encouraged my research in the area of private debt collection and allowed me to grow as a researcher. His advice on my research is priceless. I would also like to thank the other members of the International Business Law Branch of CEU Legal Studies Department: Professor Stefan Messmann, for encouraging me to engage in the S.J.D. endeavor, for believing in me and especially for his friendship, which means a lot to me; Professor Tibor Varady, for his constant support and advice; Professor Caterina Sganga, for the valuable comments concerning my work, for agreeing to serve as a committee member and for all the career advice she gave me. Last but not least, I would like to thank Professor Gerard McCormack, from the University of Leeds, for graciously accepting to serve as a member in my defense committee.
