Abstract: modern legislation on the contract system is in force in the Russian Federation relatively recently, but is one of the most unstable. The consequence of this instability is the problems of law enforcement and numerous disputes in the legal literature. The author identified two problems of instability of the legislation on contract system in relation to the legal figure of the state customer: the inconsistency of some norms of the Law on the contract system in terms of specifying the types of entities belonging to the state customers and the inconsistent provision of the Law on the contract system with the norms of the Civil Code. The author concludes that the only solution to the problem is the gradual harmonization of the legislation on the contract system.
