Today, like in terrestrial zones, the determination and registration of tenure in coastal and maritime zones appear to be mandatory not only from legal, social and economic perspective but also for sustainable environmental administration. In this context, there is a need to redefine and reconstruct these zones. In this study, the institutions and corporations operating in coastal and maritime zones in Turkey and current laws were established and a matrix was formed between the operations and the institutions operating in coastal and maritime zones to evaluate the current structure as a whole. Furthermore, with the objective of determining the problems seen in coastal and maritime zones, some survey and interview studies were conducted concerning the institutions and corporations operating in this field and the current situation was displayed. As a consequence of the study, it was found that the current structures in coastal and maritime zones were not adequate in terms of legal, institutional and technical points. The need for an integrated coastal and maritime zone administration was stated and some suggestions with regard to land management were put forward by developing new approaches.
