For many years now, there has been an attempt in the European Union to create a common legal framework for mortgage credit contracts and cross-border activities in the mortgage financial sector. One of the greatest challenges has been the establishment of a corresponding level of consumer protection in EU residential mortgage markets. This issue has become particularly important at the time of financial crisis. Consumers are increasingly exposed to the risk of losing their homes because of failing to fulfil, in due time, their obligations arising from mortgage loans, and thus losing confidence in the EU financial sector. Therefore, the European Union has intensified its efforts to improve consumers’ ability to inform themselves of the potential risks when entering into mortgage loans and mortgaging their real property. On 4 February 2014 the EU adopted the new rules on mortgage credits in the Mortgage Credit Directive. The main objective of the Directive is to increase the protection of consumers in EU mortgage markets from the risks of defaults and foreclosures. A higher level of protection must be ensured by consumers’ increased information capacity related to mortgage credits, as well as by developing a responsible mortgage lending practice across the EU. The Mortgage Credit Directive is also aimed at contributing to the gradual establishment of a single internal market for mortgage credits. In this chapter, the author analyses previous and current attempts by the EU to establish a uniform market of mortgage loans, and assesses the possible impact of the Mortgage Credit Directive on the protection of consumers in the market of mortgage credits and on the development of cross-border activities in the mortgage financial sector. Special emphasis is placed on the possible impact of the new EU rules on mortgages on national protection measures aimed at consumer protection at the time of financial crisis. The transposition of the Mortgage Credit Directive will undoubtedly contribute to a higher level of consumer protection when consumers enter into home loan contracts. However, the question arises whether, because of different levels of harmonisation of some rules laid down in the Directive, its implementation will actually contribute to an increase in cross-border home loans. The possibility for Member States to opt for increased consumer protection in some aspects of credit agreements when implementing the Directive, or the existence of different options for the exercise of individual rights that they may use cannot bring about an integration of mortgage credit markets.
