What is a quasi-contract, implied-in-fact contract?

IMPLIED CONTRACT VS. EXPRESS CONTRACT

“A contract implied in law, or a quasi-contract, is distinguishable from a true contract because a quasi-contract is a legal fiction, an obligation imposed by law regardless of any actual agreement between the parties.” Fraud-Tech, Inc. v. Choicepoint, Inc., 102 S.W.3d 366, 386 (Tex. App.—Fort Worth 2003, pet. ref’d); see Fortune Prod. Co. v. Conoco, Inc., 52 S.W.3d 671, 684 (Tex. 2000).
