Key Takeaways

  • Adhesion insurance contracts are standardized agreements drafted by insurers, leaving policyholders little to no bargaining power.
  • Courts often interpret ambiguous provisions in favor of the policyholder because they had no role in drafting the terms.
  • Policyholders may sometimes amend contracts through riders, but changes are limited and usually cost extra.
  • These contracts are recognized under both common law and civil law, though enforceability may differ by jurisdiction.
  • The concept originated in European legal traditions, later adopted into American jurisprudence, with insurance being one of the primary fields of application.
  • Critics argue adhesion contracts may be unfair, but courts allow them as long as terms are clear, conscionable, and not misleading.

The adhesion insurance definition is an example of a type of adhesion contract. This type of contract is drawn up between two parties, and all terms and conditions are provided by the party with the greater bargaining power or capabilities. The other party involved only has the right to refuse any terms listed in the contract and has no ability to change or draft any terms of an adhesion contract.

An insurance contract is an adhesion contract.

The biggest pro in this type of contract is that the predictability of situations is determined by the insurer.

How do Courts Rule in Lawsuits Involving Adhesion Insurance?

Courts tend to rule in favor of the policyholder in many cases involving adhesion contracts. This usually happens because there is a misinterpretation of the terms and there are no negotiations between the parties before a lawsuit.

When Adhesion Insurance Contracts Become Unenforceable

While courts frequently enforce adhesion insurance contracts, there are limits. If a provision is deemed unconscionable, unfairly one-sided, or buried in fine print without clear disclosure, courts may strike it down. This is particularly true when the insured could not reasonably understand or negotiate the terms. For example, clauses that excessively limit coverage or exclude critical protections may be invalidated. Courts also weigh whether a consumer had meaningful alternatives in the marketplace before accepting the agreement.

Can a Policyholder Ever Alter an Insurance Contract?

Some policies can be changed or amended via a rider. This is a provision under the terms of a contract that allows a policyholder to make specified changes, usually at an additional charge.

An example of this is when the policyholder of an automobile insurance policy can add a provision at a later date, such as adding additional risks to be covered or adding more names to the policy.

Advantages and Disadvantages of Adhesion Insurance

Advantages include:

  • Standardized terms that reduce administrative complexity.
  • Predictability for both insurer and insured.
  • Efficiency, since drafting separate agreements for every client would be impractical.

Disadvantages include:

  • Lack of negotiation power for policyholders.
  • Risk of confusing or misleading clauses hidden in lengthy documents.
  • The potential for insurers to use vague language that leaves interpretation to the courts.

Because of these risks, many jurisdictions emphasize the doctrine of reasonable expectations, meaning courts will enforce what an average policyholder would expect coverage to include, even if the fine print suggests otherwise.

Where are They Legally Acknowledged?

Adhesion insurance contracts are acknowledged in both common law and civil courts, but the effects they have in those jurisdictions may vary.

It can also be noted that the lack of equal distribution of bargaining power can also set adhesion contracts apart from other types of traditional agreements.

Real-World Examples of Adhesion Insurance Contracts

Adhesion insurance contracts are common across multiple industries, including:

  • Auto insurance – standard policies where exclusions and limitations are pre-set by the insurer.
  • Health insurance – agreements that dictate covered procedures and networks without negotiation.
  • Life insurance – policies that set payment terms, exclusions, and payout structures in advance.

In all of these cases, the insured must either accept or reject the entire agreement, with limited room for customization.

Where are the Origins of Adhesion Contracts?

The time when the concept and term "adhesion contract" was used in American legal jargon was around 1919. Since that time, the term has been used definitively by courts and legal professionals.

However, instances of adhesion contracts can be seen in 18th and 19th century France in causa civilis cases where the teachings of the Roman Catholic church taught that in certain cases a contract must gratuitously benefit one of the parties involved.

Types of adhesion contracts can also be seen in Hindu law throughout the caste system.

The theory of equivalents provided for the enforceability of adhesion contracts and encouraged them on an international scale. This characteristic made adhesion contracts a natural fit for the insurance industry, which had been the first to realize "judicial risk."

Rates and premiums are then determined by several factors:

  • Uniform provisions.
  • Actuarial tabulations.
  • Consistent court interpretations.
  • Laws of large numbers.

These factors help insurance companies determine the legal liabilities and actual predicted risks of the policies they propose.

The Doctrine of Adhesion is the legal theory allows for interpretation of ambiguities by the courts and prevents the complications that standardization can cause.

Perhaps the first example of this is Bekken vs. Equitable Life Assurance Society of US. In this case, 25 days after the application for a policy was taken, but the company had neither accepted nor denied coverage.

The court established that the insured can only "adhere" to the terms of a life insurance policy that the insurer has established during this instance of an adhesion contract.

Judicial Treatment and Doctrines Affecting Adhesion Insurance

Over time, U.S. courts developed doctrines to balance the scales between insurers and consumers:

  • Doctrine of Adhesion – Ambiguous terms are interpreted against the insurer that drafted the policy.
  • Doctrine of Reasonable Expectations – Even if exclusions are clearly written, coverage may be enforced if the insured could reasonably expect it under ordinary circumstances.
  • Public Policy Limitations – Courts may strike provisions that go against consumer protection standards or public interest.

These judicial safeguards are especially relevant in insurance, where consumers rely heavily on coverage during crises.

What are the Effects of Adhesion Theory in California?

As far back as 1910, adhesion contracts are cited as being difficult to decipher and full of provisions that the policyholders may or not be aware of. Courts must hold to the spirit of the contract while trying to understand that such contracts may be confusing to the insured.

The main goal of the courts was decided that they should determine ambiguity in these contracts. It was also determined that ambiguity, in most instances, applied to areas that were not covered, rather than to specific terms. Some have concluded that the purpose of the term adhesion contract is to define a set of rules by which types of insurance contracts are created.

In order to provide more precise rules, it may be perceived that a more specific system of contract law and a more definitive interpretation of specific rulings are needed and that tort "rules" which have been used previously only muddy the legal waters when it comes to cementing the terms of adhesion contracts.
