Mutuum (Loan for Consumption)
The contract of mutuum was a loan of fungibles, that isi of articles that are consumed in the using. It arose whenever one person delivered to another things dealt in by weight, measure, or number, such as oil, wine, corn, money, bronze, silver, or gold, with the intention that the transferee should become the owner of the things delivered, subject to an obligation on his part to return, not the identical things received, but others of the same kind, quality and amount.
Mutuum, unlike the other real contracts, was a stricti juris negotium. The action to which it gave rise and by which the borrower was forced to make return was condictio certi.
Mutuum was a gratuitous loan. The buyer was required to return only the exact amount of property (oil, money, etc.) that he had received, even though guilty of delay in making return. Even in the case of a loan of money interest could not be recovered on the contract of mutuum.
How Made. The contract was made by the simple delivery of the property. Actual delivery was essential unless the borrower was already in possession. Since it was contemplated that the borrower should become the owner of the property, the lender had to be himself the owner. Unlike the other real contracts, which could be created by one having merely possession, the contract of mutuum coukl be created only by the owner of the property.
