What distinguishes "implied contracts" from other types of contracts?

Implied contracts are unique in that they arise from the actions, behaviors, or circumstances of the parties involved, rather than from written or verbal agreements. This means that an implied contract is established when a person's conduct suggests that they have an agreement with another party, even if no formal contract has been explicitly stated. For instance, when a person orders a meal at a restaurant, it’s implied that they will pay for the food upon receiving it; the agreement is based on the actions taken rather than any written or spoken words.

This distinction highlights the nature of implied contracts as being inherently based on the context and interactions between the parties, rather than requiring any specific form or witness. Other choices focus on characteristics like the necessity of being written or the requirement for a verbal agreement or witness, which do not apply to implied contracts. An enforceable implied contract does not rely on those elements, but instead on the reasonable expectations generated by the actions of the parties involved.
