I’m looking for a property deed of an estate in Romania, formerly belonging to Hungary. Where and how can I find it?

The National Archives of Hungary does not keep any land registries or copies of land registries, or any other district court or General Court documents generated outside the borders. But it is not impossible that there are documents related to land purchase or expropriation can be found in the documentation for example of the Ministry of Agriculture. For successful research the following information are required: What was the settlement of the property? Who were the owners? How long did they have property? What was the property land register reference number? The research, however, should be start definately in the territorial archive, because they keep the estate administration of the District Court and forensic documents.
