Contract formation under russian legislation

Under russian legislation a contract is considered formed if parties settled agrement on all essential terms of the contract. Essential terms of the contract are terms about the subject of contract, terms stipulated by laws or other legal acts as essential or necessary terms for that kind of a contract.

The Russian legislation defines essential terms for each kind of contract (purchase and sell, rent, contract for work and labor etc.).

In addition, under the Russian legislation essential terms of the contract are recognized the terms about which agreement shall be settled upon the statement of one party.  

It means that in case  the parties shall sign additional agreement or appendix of the contract that regulate the parties' relations or a part of parties' relations  under the contract, and later the parties do not sign the above said additional agreement or appendix of contract, the contract can be recognized not formed. 

Contracts between legal entities shall be formed in a written form.

In practice it means that the best way of contract formation is contract signing by all parties to the contract, as opposed to forming the contract by means of making an offer and acceptance, but the Russian legislation does not forbid contract formation that way.
