Loan agreement
Loan agreement (Сommodatum) - an agreement by virtue of which one party (the lender or the commodant) transferred to the other party (the borrower or the commodative) an individually defined thing for temporary gratuitous use, and the borrower assumed the obligation to return that the same thing is intact after the expiration of the contract.
A loan agreement is a real agreement, it is considered concluded from the moment the property is actually transferred for use.
The subject of the loan agreement is corporal, irreplaceable, individually defined things (a house, a plot of land, a specific tool of labor, etc.), but not necessarily in civil circulation.
A loan agreement is a bilateral agreement.
