What is a Contract of Adhesion?

Contract of Adhesion Examples Across Industries

Contracts of adhesion are prevalent across many industries because they offer businesses efficiency and standardization in dealing with large volumes of customers or transactions. You’ve likely signed several without necessarily knowing the term.

Here are some common examples where you’ll find standard form contracts (adhesion contracts):

• Insurance Policies: Your auto, home, or health insurance policies are classic examples. The insurer drafts the terms, and you choose whether or not to purchase the policy based on those pre-set conditions.
• Software Licenses (EULAs): Those End User License Agreements you click « agree » to before installing software? Definitely contracts of adhesion.
• Online Terms and Conditions: Agreements for social media platforms, streaming services, e-commerce sites, and mobile apps fall into this category.
• Employment Agreements: While some high-level executive contracts are negotiated, many standard employment agreements, especially concerning arbitration or confidentiality clauses, are presented on a take-it-or-leave-it basis.
• Consumer Credit Agreements: Applications and agreements for credit cards, mortgages, and personal loans often contain standard, non-negotiable terms set by the lender.
• Leases and Rental Agreements: Standard residential lease agreements provided by large property management companies frequently function as adhesion contracts.
• Tickets and Waivers: Even concert tickets, travel bookings, or gym membership waivers often include fine print with terms you agree to upon purchase or use.

Are Contracts of Adhesion Actually Enforceable?

A common question is: if you didn’t really negotiate, is the contract even legally binding? Generally speaking, yes, contracts of adhesion are legally enforceable. The efficiency they provide is recognized as necessary for modern commerce. However, because of the potential for unfairness stemming from unequal bargaining power, courts scrutinize these contracts more closely than agreements negotiated between parties on equal footing.

Two main legal doctrines are used to evaluate whether the terms of an adhesion contract should be enforced:

The Doctrine of Reasonable Expectations

This doctrine asks whether a reasonable person in the adhering party’s position would expect the terms included in the contract.

• Bizarre, oppressive, or contradictory terms may not be enforced
• Hidden fine print or overly complex legal language can raise concerns
• Courts assess whether the weaker party was adequately notified of the terms

The Doctrine of Unconscionability

This doctrine applies when contract terms or the circumstances under which they were agreed are so unfair that they are unacceptable in the eyes of the court.

• Procedural Unconscionability: Focuses on how the contract was formed, including lack of meaningful choice, use of fine print, complex legal language, or pressure tactics
• Substantive Unconscionability: Focuses on the terms themselves, such as those that are excessively one-sided, commercially unreasonable, or unfairly limit rights

Contra Proferentem

Under this principle, any ambiguity in a contract is interpreted against the party that drafted it. This is particularly relevant in adhesion contracts, where only one party controls the wording of the agreement.

Clickwrap/Sign-in-Wrap Validity

In digital agreements, contracts are generally enforceable when users are required to actively agree—such as clicking “I accept”—and when the terms are clearly presented and accessible at the time of acceptance.

Are Adhesion Contracts Fair or Exploitative?

Adhesion contracts sit at the intersection of efficiency and fairness.

Courts have repeatedly intervened when adhesion contracts overstep boundaries. One notable example:

Real Case Example: Discover Bank v. Superior Court (California, 2005)
In this case, an arbitration clause was buried inside a credit card agreement. The court found it procedurally and substantively unconscionable because the consumer had no real choice and the clause unfairly shielded the company from liability. The clause was struck down — proving that not all click-to-agree terms will hold up.

When Might a Contract of Adhesion Be Invalidated?

While generally enforceable, specific circumstances can render parts or all of an adhesion contract invalid. Beyond failing the reasonable expectations or unconscionability tests, other factors can come into play.

A court might refuse to enforce an adhesion contract if:

• It Violates Public Policy: The contract requires an illegal act or goes against strongly held societal principles.
• Terms are Highly Ambiguous: If a key term is so unclear that its meaning cannot be reasonably determined, courts often interpret the ambiguity against the drafting party (the principle of contra proferentem).
• Lack of Capacity: One party lacked the legal ability to contract (e.g., was a minor or mentally incompetent). This is a general contract defense but applicable here.
• Fraud, Duress, or Undue Influence: If the weaker party was tricked, forced, or improperly pressured into agreeing. Again, these are general defenses relevant to adhesion contracts.
• It Fails to Meet Digital Contracting Standards: Especially relevant today, as explored next.
