The article discusses the issues of legal support for the use of electronic digital signatures and other analogues of handwritten signatures in electronic documents in the Republic of Kazakhstan. An electronic (digital) signature is an integral element of the implementation of the will of the participants in civil circulation in the digital environment. As an analogue of a handwritten signature, an electronic (digital) signature may be used that is not tied to a specific technology for its formation, provided that its use is provided for by law, other regulatory legal acts or an agreement of the parties. Special attention should be paid to the use of a new analogue of a handwritten signature based on electromagnetic resonance technology. The legal regulation of analogues of a handwritten signature and relevant public relations in the legislation of the Republic of Kazakhstan is not fully reflected. This, in particular, is expressed in the absence of a clear distinction between the concepts of «electronic signature», «digitalsignature» and «electronic digital signature». Analysis of the current legislation in the field of electronic document management allows us to conclude that it is necessary to further improve the legal regulation of electronic (digital) signatures.
