The development of the market relations in Ukraine had caused radical changes in socioeconomic life, which led to the introduction of new categories in business turnover. The main foundations of the legal solution of these issues have been reflected in the Civil code of Ukraine, which, however, is currently in the stage of permanent renewal. The practice of law enforcement confirms that, in connection with the significant renewal of the system of private legislation, there is an objective need for theoretical analysis and scientific generalization of the existing realities. In the context of the above, it is worth emphasizing the great importance that the legal actions play at the present time, in connection with which it is advisable to also take into account their place in the system of legal facts.
 A legal action is an action of a person aimed at acquiring, changing or terminating civil rights and obligations. They are divided into unilateral, bilateral and multilateral. A unilateral legal action is the deed of one party, which may be represented by one or more persons. A bilateral or multilateral legal action is an agreed deed of two or more parties. The general provisions on obligations and contracts shall apply to legal relations arising from unilateral legal actions, if this does not contradict the acts of civil legislation or the essence of the unilateral legal acton. At the same time, in judicial practice, sometimes there are difficulties associated with the qualification of certain deeds as legal actions.
 Legal actions, of course, will continue to be one of the most common grounds for the emergence, change and termination of civil legal relations, and the correct definition of the legal nature of a person's deeds as a legal action is extremely important for the correct resolution of disputes between participants in civil transactions, compliance with the principles of legality, reasonableness, good faith and justice. In the conditions of the development of economic processes and modern technologies, the methods of performing legal actions, the requirements for their form, will be improved, and therefore it seems important in the future to update the approaches to the methods of protecting the rights and interests of their participants.
