The article is devoted to the study of the peculiarities of economic and legal support for the activity of an enterprise that is a resident of Diya City. Based on the analysis, it was concluded that in the conditions of the digital economy there can be economic systems in which there are intra-system organizational economic legal relations and intra-economic legal relations. In intra-system organizational economic relations, their participants are legally equal, therefore management in the form of coordination within the system will be implemented on the basis of economic dominance, which ensures mutually beneficial interaction between the participants of this system. A resident of Diya City, created in the form of a company with limited or additional liability on the basis of an economic contract, can transfer the powers of the executive body to another legal entity. It is expedient to define the requirements for such a legal entity as fully as possible in the Diya City resident statute. The contract for the performance of the powers of the executive body of the resident of Diya City must contain the following essential conditions: subject, price, term of the contract, financial and economic indicators that must be achieved by the resident of Diya City as a result of management, deadlines for their achievement, conditions for control and reporting, grounds for early termination of the contract. Before concluding an agreement on the transfer of powers to the executive body of the resident of Diya City to comply with the legal economic order on the basis of the previous agreement, it is advisable for the parties to organize mutual checks: audit, compliance, due diligence, etc. On the basis of an economic outsourcing contract, including an IT outsourcing contract, a resident of Diya City can involve professional, highly specialized companies in his own economic system. Such a feature of outsourcing as the duration of the relationship between the parties in this relationship will be optional, as it may arise for the implementation of a certain project. Digitization allows the enterprise to move from such organizational forms as management, regulation, control mainly to coordination, because with digitalization, the enterprise creates digital structural units and digital management bodies, and digital (virtual) workplaces become the basis.
