Aggregatio Mentium Law and Legal Definition

Aggregatio Mentium is a Latin term meaning meeting of minds. Aggregatio mentium is an essential element in a contract requiring actual consent by both parties to the formation of a contract. Hence, in aggregatio mentium, mutual consent should be attained with the assent of both parties. Aggregatio mentium is indispensable to every contract.[Aspinwall v. Bd. of Comm'Rs, 63 U.S. 364 (U.S. 1860)]
