is a form of insurance carried out on the basis of a voluntary agreement concluded between insured and insurer. The rules of voluntary insurance, which determine general conditions and procedure of its conduct, are established by insurer independently in accordance with legislative and other regulatory insurance instruments. Specific insurance conditions are determined during conclusion of an insurance agreement. Unlike compulsory insurance, in which an insured is obliged to insure its property or liability to the third parties by law, the insurance agreement of this insurance type is voluntary.
