This is a socio-legal study concerning debt and debt collection. The frame of reference of this study on the legal sociology of debt is the international aspects of debt and debt collection. The debtor and creditor will be private persons or corporations separated by national borders. As a result, the author gives greater weight to business-to-business (commercial) debts. Debt means something different in the business world, the risk of non-payment is inherent to commercial activities. Business creditors are able to calculate and ""manage"" the risk of non-payment. Consumer debt deserves to be dealt with as a social problem, commercial debt is an economic phenomenon. For this reason the study focuses on the enforcement of monetary claims rather than debt as a social problem.;The book is in three parts. These parts consider judicial, extra-judicial and cross-border methods of debt collection. Comparisons are made between England, Germany and Turkey, and EU aspects are also considered.
