Inequality of bargaining power

Inequality of bargaining power is a legal and economic concept describing a contract negotiation in which one party has substantially more and better alternatives than the other, giving that party greater leverage to secure favorable terms while the weaker party faces pressure to accept unfavorable ones. A party that can credibly walk away from a deal holds a structural advantage over a party that cannot. Because the stronger party's superior alternatives let it dictate terms rather than genuinely negotiate them, the doctrine is understood as undermining freedom of contract, the principle that parties bargain and agree on terms as equals, and as producing what economists call a market failure, where the ordinary corrective pressure of competition breaks down. Legal systems respond to severe bargaining power disparities by letting courts impose mandatory terms on a contract or decline to enforce a term altogether. This intervention recurs in consumer protection, employment relationships and landlord tenant arrangements, contexts in which one party typically holds much greater economic power and access to information than the other.
