If you are going to stay in Turkey for a long period and buy a property, get married, open your business or seek employment, then you need to know the main Turkish laws. However, it is also important to know the Turkish legislation to avoid getting into a trouble even if you are a tourist and you are going to spend just one or two weeks in the country.
The laws in Turkey that control everyday life of its citizens do not actually differ greatly from the laws in other countries. However, there are some peculiarities, which you should better know in advance. For instance, it is forbidden to smoke in the street, all public places and public transport, otherwise you will be fined. The mount of Ararat is a special military zone and you cannot even take photos of this mountain.
But special attention should be given to the laws, which for example describe the procedure of buying property in Turkey, marriage and divorce procedures, employment procedure and taxation system. This is particularly important because there can be differences for locals and for foreigners.
