An adhesive contract is one that is written and issued by one party to the contract and does not require the signature of the other party to the contract to be valid. Insurance contracts are adhesive contracts since the contract is written and issued by the insurance company and the insured is not required to sign the policy. If a dispute arises concerning the terms of the contract, courts will generally interpret the contract conditions in favor of the party that did not write the contract -in this case, the insured. (See Unilateral Contract).
