Thank you for your answers. This is rather more complicated than I made it seem. The girls are aware that they need specialist help if they are to sort this out, but they are not having much luck in obtaining it, and are wondering if it will be worth in the long run, it will probably cost more than the estate is worth. Their father bought a house on the west coast of Turkey when he first went there, but he had recently moved to a remote town in eastern Turkey. He also had a Turkish bank account. He was retired, and his income was from pensions paid into his UK bank and he accessed this money via ATMs in Turkey. He never told his UK bank that he was living in Turkey, and used his sister's UK address for mail. The Foreign Office gave the girls addresses of several lawyers in Turkey that they thought would be able to help them, but all of these lawyers came back saying they couldn't help, except one who said he had done a search and found no property registered to the deceased, but he couldn't help further.
