Meaning
Measured against informal promises and gratuitous commitments, enforceable equity agreements require a reciprocal exchange of value between contracting participants. Under contract doctrine, legal consideration represents the benefit received or detriment suffered by a party entering into an agreement. The requirement validates equity transfers, intellectual property assignments, and employment contracts by confirming that both sides commit something of value.
Bare promises or past performance without present exchange fall outside this enforceable boundary.
Bargained Exchange
Contractual enforceability depends on demonstrating that each party acted to secure the promise of the other. In startup formation, legal consideration appears when founders assign pre-existing software rights to a new corporation in return for initial equity. Legal frameworks do not require monetary parity between swapped promises, provided both parties freely negotiate the exchange terms.
Tribunals evaluate whether a genuine detriment occurred rather than assessing financial fairness. Promissory estoppel acts as a narrow exception when reasonable reliance replaces explicit reciprocal value. Without this underlying exchange, executive non-compete agreements and equity vesting adjustments fail for lack of enforceability.
Nominal Sufficiency
Modern commercial law accepts minimal physical payment as valid contractual value. A payment of one dollar or a token equity assignment satisfies formal requirements to bind an option contract or IP release.
Contract Modification
Altering existing commercial agreements requires fresh mutual value to prevent unilateral terms. When founders adjust equity splits or extend vesting schedules post-founding, legal consideration must support the revised contract. Promising to perform an existing contractual duty provides no new value to support modified obligations.
Corporations satisfy this requirement by offering accelerated vesting, revised severance benefits, or additional options alongside contract updates.
