For leases, that fall fully of partly (except business parks) under the scope of the MRG (Act on Tenancy Law), a legal regulation dealing with tenant deposits was inserted into the MRG with effect as of 1st April 2009. Even if these rules, at first glance, only put the previous practice in relation to tenant deposits into words, on closer examination there are some notable differences. The legal reference to reclaim the tenant deposit via Non-Contested Proceedings has to be seen as a true innovation. Although this creates new questions that can only be resolved in the course of time, the regulation of tenant deposits can be seen as a step in the right direction.
