The German Pfandbrief Act of 22 May 2005 replaced the Mortgage Bank Act, which had been applicable up to that point. The specialized principle for pfandbrief banks was thus eliminated, and today all credit institutions are allowed to conduct pfandbrief transactions if they fulfill the requirements and have received the appropriate permission. The Act also ushered in a harmonization with reforms in the legal field relevant to credit institutions, as well as with developments related to European integration. As the only commentary specialized in this topic on the market, this work provides orientation for the application of the Pfandbrief Act. Special attention was dedicated to documenting all known and practice-relevant problems concerning the Pfandbrief Act and to providing appropriate solutions. The annex includes the texts of the Net Present Value Regulation, of the three Regulations on the Determination of the Mortgage Lending Value (mortgages, airplanes, ships), the Cover Register Statutory Order and the Funding Register Statutory Order (sections 22a - 22o KWG). As a result, this work is an essential and comprehensive reference work for all issues concerning the law on the pfandbrief. Also included: the legislative explanations regarding the reforms 2009 and 2010.
