Distinguish executed from executory consideration.

The definition: the price of the promise — something moved (an act, a forbearance, or a return promise) at the promisor's request: what the promisor bargains for in exchange for his promise. Nudum pactum — the bare promise is unenforceable (the common-law core): "something of value in the eye of the law" given in exchange. The Nepali position's evolution (the exam's high-value paragraph): the Contract Act 2056's consideration requirement — the prescribed-case era's working rule "no consideration, no contract" (the Chitra Bahadur Karki v. Maniram Agrwal line, decided under the 2056 Act) — versus the Muluki Civil Code 2074's design: consideration not enumerated among the contract's definitional essentials (the civil-law turn: the agreement's enforceability resting on consent-and- object; the gratuitous contracts — gift, promise without price — recognized in the Code's own chapters) — the doctrinal shift to state carefully: from the Anglo-Indian validity gate to the civilian taxonomy element. Do not overstate: in commercial practice the exchange-contract still requires its bargain's indicia, and the case law's reliance values remain.
