[en] This study focuses on the establishment and development of general aspects of the legal system of the Republic of Estonia, in comparison with Ukrainian legal transformations in the context of the EU integration. Ukraine's way to achieving a European integration involves a number of issues that should be resolved, in particular corruption, unreformed judiciary, ongoing 'oligarchization', shadow economy, the influence of corporate interests, and insufficient economic development. Authors used comparison, analysis, and modelling methods. Attention is also paid to the procedural link of Estonian civil procedure to pan-European provisions, the application of common European procedures in the judicial proceedings of Estonia as an EU Member State. The authors have engaged in comparative analysis of Ukrainian civil procedural law and the corresponding law of Estonia Study concludes that adaptation of European democratic standards by the Ukrainian judiciary system would be difficult without studying legal experiences of other EU countries.
