Written by attorneys · grounded in primary & secondary sources — see below
A contract or term is unconscionable when it exhibits both procedural unfairness in formation and substantive unfairness in its terms. Procedural unconscionability arises from defects in the bargaining process such as lack of meaningful choice or unequal bargaining power. Substantive unconscionability arises from terms that are overly harsh or one-sided.

Mistake Rendering Enforcement Unconscionable
Pavel Petrov agreed to sell equipment to Pinnacle Holdings under a pricing formula based on an index that both parties assumed would track actual costs. When the index diverged sharply, enforcement would impose a massive loss on Pavel. The court refused enforcement because the mistake produced an unconscionable result.
Unconscionable Separation Agreement
Patricia Patel and Preston Pratt signed a separation agreement that left Patricia with almost no assets after years of homemaking. Considering the parties' economic circumstances, the court found the agreement unconscionable and refused to bind itself to its terms.
Premarital Agreement Term Unenforceable
Peter Park signed a premarital agreement waiving all spousal support. After a material change in circumstances left him in substantial hardship, the court refused to enforce the term because it was unconscionable at signing and enforcement would cause hardship.
Unconscionable Limitation on Damages
Prime Logistics sold consumer goods to Pablo Perez under a contract excluding consequential damages for personal injury. The limitation was prima facie unconscionable, so the court refused to enforce it and allowed Pablo to recover full damages.
Court Limits Unconscionable Term
Premier Manufacturing contracted with Prism Analytics under terms that included an unconscionable penalty clause. The court refused to enforce the penalty but enforced the remainder of the contract after limiting the clause to avoid an unconscionable result.
Court Orders Revised Agreement
Patrick Phan and his spouse submitted a separation agreement the court found unconscionable. The court directed the parties to submit a revised agreement or issued its own orders for property division and support.
