Sense: adjective/2

While unenforceability refers specifically to a contract or law that a court will not put into effect, invalidity is a broader term meaning that something has no legal effect from the start. A contract may be valid between the parties but still have unenforceability — for example, if it violates public policy or misses a required legal formality. Nullity goes further: a null contract never existed in the eyes of the law at all. Voidness is similar and means the agreement has no legal force whatsoever from the beginning. In practice, a lawyer might argue unenforceability when the contract itself is not illegal but simply cannot be enforced through court action, whereas invalidity or nullity would apply when the whole agreement fails to meet the basic legal requirements from the start. For example, a contract signed under threat would be void, while a contract merely missing a required signature may be unenforceable but not void.

Etymology

LatinFrenchEnglish

From un- (a prefix meaning 'not') + enforceability, which comes from enforce (to make something happen or be obeyed using force or authority) + -able (meaning 'possible to do') + -ity (forming a noun meaning 'quality or state'). The root word enforce entered English from Old French enforcir ('to strengthen'), which came from Latin in- ('in') + fortis ('strong').
