What type of agency is created by the actions, conduct, and words of the parties without an explicit request?

The correct answer is implied agency. This type of agency is established through the actions, conduct, and words of the parties involved, rather than a formal agreement or explicit request. In situations where an implied agency exists, the behavior of the parties may indicate that they intend to create a principal-agent relationship, even if they haven't explicitly stated so.

For instance, if a property owner allows a person to act on their behalf in discussions about selling their property, the owner's actions can suggest an implied agreement, even without a written contract or direct permission. This principle relies on the idea that both parties have acted in a way that suggests consent to an agency relationship, making it legally binding.

Other types of agency, such as express agency, are formed through a clear, explicit agreement, often written, while quasi agency involves a situation where an agency-like relationship arises under certain conditions, like benefiting from someone else's actions without a formal agreement. Agency by ratification occurs when a principal approves the acts of an agent that were done without prior authorization.
