Implied notice is notice inferred from facts that a person had a means of knowing and which is thus imputed to that person. It is a situation in which law considers a person to have notice of a particular fact because s/he knew of sufficient other facts such as would cause a reasonable person to make inquiries and then gain additional knowledge.
It is a notice inferred or imputed to a party by reason of his/her knowledge collateral to the main fact. Presumption of implied notice can arise because of legal relations with a person who has notice. For example: principal-agent relation. Exercise of reasonable observance and watchfulness is enough to have implied notice. Implied Notice is also called Indirect notice.
