A contract where one party is obligated for the benefit of another without receiving any advantage in return is called?

A contract where one party is obligated for the benefit of another without receiving any advantage in return is referred to as a gratuitous contract. This type of contract is characterized by its non-reciprocal nature; one party (the promisor) provides a benefit to another party (the promisee) without expecting any form of compensation or return benefit.

In gratuitous contracts, the focus is on the intent to confer a benefit rather than to engage in a mutually beneficial exchange. Examples include donations or gifts, where the giver does not require anything in return. This contrasts with onerous contracts, where both parties have obligations and expect consideration from each other. Aleatory contracts involve events that are uncertain and depend on chance, while unilateral contracts are those where only one party makes a promise or undertakes an obligation. The defining aspect of a gratuitous contract is its one-sided nature, reinforcing the understanding of the term within contract law.
