This chapter introduces promissory estoppel as a reliance-based substitute for consideration when a promise reasonably induces action or forbearance. In The Arkenstone, the emotional and strategic stakes help illustrate why reliance can make nonbargained promises legally significant.
Doctrinal map
R2d § 90’s four-part test — clear and definite promise, foreseeable reliance, actual reliance, injustice avoidable only by enforcement — produces enforceability where consideration alone would not. Ricketts v. Scothorn is the classic gratuitous-promise case. Conrad v. Fields shows the test applied to an educational-support promise. Hoffman v. Red Owl extends the doctrine to pre-contract negotiations. Drennan v. Star Paving uses it to keep subcontractor bids open. The student leaves with a map of how reliance interacts with consideration across these archetypes.

Cases
- Ricketts v. Scothorn 57 Neb. 51, 77 N.W. 365 (1898) A gratuitous promise that induces foreseeable, substantial action in reliance becomes enforceable to the extent justice requires. Reliance can supply what bargain does not.
- Conrad v. Fields 2007 WL 2106302 (Minn. Ct. App. July 24, 2007) Promissory estoppel requires a clear and definite promise, foreseeable reliance, actual reliance to the promisee's detriment, and injustice that can only be avoided by enforcement. Tuition for a course of study undertaken in reliance is a recoverable detriment.
- Hoffman v. Red Owl Stores, Inc. 26 Wis. 2d 683, 133 N.W.2d 267 (1965) Promissory estoppel under R2d § 90 reaches promises made during contract negotiations, not only finalized promises. Where one party makes promises that induce reasonable reliance during negotiations, and the deal then falls through because the promisor changes terms, the relying party may recover reliance damages.
