A Title Deed, known as TAPU in Turkish, is the official document that proves ownership of a property in Turkey. It is issued by the General Directorate of Land Registry and Cadastre (Tapu ve Kadastro Genel Müdürlüğü) and is essential for completing any real estate transaction. For foreign investors, the Title Deed is a critical document, especially when applying for Turkish Citizenship by Investment (CBI).
