In order for a foreign court judgment or administrative act of a foreign authority to be valid in Greece, it must be recognised by a Greek court by the issuance of a judgment through the competent Single-Member Court of First Instance. Very often the Decentralised Administration, Department of Foreigners, is requested by the Decentralised Administration, Department of Foreigners, to recognise divorce decisions of foreign courts. In this case, such an application must be made.
