Why A is correct
A unilateral contract is one in which only one party makes a legally enforceable promise. In insurance, the insurer promises to pay covered losses that occur during the policy period, and that promise is enforceable against the insurer. The insured does not promise to suffer a loss or to pay claims; the insured's premium is consideration that completes the bargain, not a promise to perform some future act. This distinguishes insurance from bilateral contracts, in which each party makes enforceable promises to the other, such as a construction contract in which the builder promises to build and the owner promises to pay. Recognizing insurance as unilateral helps explain why the insurer's obligation is conditional on events like loss occurrence and premium payment.
Why the other options are wrong
- B) Simultaneous mutual promises describe a bilateral contract; insurance is unilateral because only the insurer makes a promise to perform, while the insured's payment is consideration. The insured's only obligation is to pay the premium, which completes the bargain rather than constituting a promise of future performance.
- C) The insured never promises to pay claims on behalf of the insurer; the insured pays premiums as consideration, and the insurer is the only party promising to pay covered losses.
- D) Cancellation rights are governed by the policy's own terms and by statute, not by the contract's unilateral nature, which concerns who makes an enforceable promise. Cancellation and renewal depend on the policy's notice provisions and the statute, not on whether the contract is classified as unilateral.
Memory hook
Unilateral = one-sided promise: the insurer promises to pay; the insured's premium keeps it alive.
