Final answer:
Constructive notice is a legal concept that applies when a person ought to have knowledge of a fact, despite lacking actual knowledge, based on circumstances and expected prudent inquiry.
Step-by-step explanation:
The fact which should have been discovered because of the person's actual notice of circumstances, and the inquiry that a prudent person would have been expected to make, is known as constructive notice. Constructive notice is a legal concept that means a person or entity should have known, as a reasonable person would have, of a legal action taken or condition existing, even if they did not have actual knowledge of it. For example, if someone purchases property, they have constructive notice of the property's legal status and claims on it through public property records.
