In 2020, the essential terms of the contract can be changed, including in terms of advances. The Office listed the conditions under which this is possible:
the new advance payment does not exceed the limit established by law for the relevant contract. For example, an advance on a contract for the construction of regional and municipal facilities (if subsidies from the federal budget are allocated for their financing to the region) cannot exceed 50% of its amount;
advance payment is provided for by the contract;
the change is made by agreement of the parties at the initiative of the supplier (contractor, contractor);
circumstances that did not allow the execution of the contract on the terms provided for by him arose due to the coronavirus.
