The aim of the article was to discuss conceptual ideas on the state of legal support of the electoral process in Denmark, New Zealand and the United States, as well as to identify opportunities to use the positive experience of these countries in Ukraine. The article uses such methods as dialectical, comparative law, system-structural, formal-dogmatic, modelling and forecasting. It should be noted that, despite the ability of EU countries to introduce their own electoral legislation and choose the electoral system, the exercise of the right of everyone to vote or be elected is ensured by compliance with international standards of organization and conduct of elections. It is concluded that the countries studied: Denmark, New Zealand and the United States generally adhere to the rule of law and the electoral process is well organized. It is stated that the due legal support of the electoral process is a tool for the formation of legitimate representative bodies of state power and local self-government. In addition, it is proposed to implement in the Ukrainian electoral legislation the positive experience of some countries, as well as to identify possible ways to improve it.
