Civil legislation is based on the recognition of the equality of participants in the relations it regulates, the inviolability of property, freedom of contract, the inadmissibility of arbitrary interference by anyone in private affairs, the need for the unhindered exercise of civil rights, ensuring the restoration of violated rights, and their judicial protection. Citizens (individuals) and legal entities acquire and exercise their civil rights by their own will and in their own interest. They are free to establish their rights and obligations on the basis of the contract and to determine any terms of the contract that do not contradict the law.
