Due to technological and social developments, humanity has reached a modern World. One of the common features of daily life that we live in this modern World is that it is full of risks and uncertainties. Risk is one of the basic elements of insurance. Throughout history, human beings have struggled to eliminate or reduce this risk and wanted to reduce the losses that they cannot meet individually. This understanding of sharing formed the basis of the concept of insurance. Professional liability insurances are embodied in the `Liability Insurances` subtitle within the scope of the insurance and have improved over the years.
