Contract litigator here. Unconscionability is a powerful defense but it has a high bar. Let me explain the two-part test that courts use so you can assess whether your situation qualifies.
Courts analyze unconscionability in two dimensions: procedural and substantive. Procedural unconscionability looks at the circumstances of contract formation. Was it a take-it-or-leave-it adhesion contract? Was there unequal bargaining power? Were key terms hidden in fine print or dense legalese? Was there time pressure to sign? The more of these factors present, the stronger your procedural argument.
Substantive unconscionability looks at the actual terms themselves. Are they unreasonably favorable to one party? Common examples include one-sided indemnification clauses, mandatory arbitration with the arbitration costs borne entirely by the weaker party, liability caps that are absurdly low relative to potential damages, and unilateral modification clauses that let one party change terms without consent.
The critical thing to understand is that most courts require BOTH procedural and substantive unconscionability, though they use a sliding scale. The more extreme the substantive unfairness, the less procedural unconscionability you need to show, and vice versa. At 90K in dispute, this is absolutely worth having a litigator review the specific contract language. Many of us will do a quick review and give you an honest assessment of your chances before you commit to representation.
