In Turkey, only trading companies established according to the laws of their respective countries and having legal personality may acquire real estate and limited rights in rem as foreign legal persons. Legal persons other than such trading companies (foundations, associations etc.), on the other hand, may not acquire real estate and may not have rights in rem. Acquisition of real estate by trading companies established in foreign countries according to the laws of their respective countries and having legal personality, on the other hand, may be granted in exceptional cases and is deemed possible only when stipulated under the provisions of international conventions or special laws. Among the specific codes inclusive of provisions on this matter are Law No. 6491 on Turkish Oil, Law No. 2634 on Tourism Incentive, and Law No. 4737 on Industrial Zones. NOTE: With respect to mortgages, an exception is stipulated whereby there is no limitation as to the mortgages to be created over the property in favor of foreign natural and legal persons.
