Nov 17, 2025

Overview

The transcript explains equitable contracts, focusing on promissory estoppel and promissory restitution, and illustrates promissory estoppel with a family promise example.

Contracts in Equity: Purpose and Scope

  • Aim to achieve justice and fairness beyond strict legal rules.
  • Reinforce trust in the legal system and obligations.
  • Provide recovery when technical contract law denies relief.

Types of Equitable Contracts

  • Promissory estoppel (detrimental reliance).
  • Promissory restitution.

Promissory Estoppel: Core Elements

  • Promise made that should reasonably induce action or forbearance.
  • Actual reasonable reliance by the promisee on the promise.
  • Reliance leads to action or forbearance.
  • Reliance causes detriment to the promisee.
  • Equitable enforcement may provide recovery despite lack of consideration.

Gift Promise vs. Enforceable Obligation

  • Gratuitous or gift promises lack a bargain-for-exchange.
  • No consideration means no enforceable contract at law.
  • Equity may enforce if reliance is reasonable and detrimental.

Example: Grandfather’s Law School Promise

  • Grandfather promises to pay for law school; no bargain, no consideration.
  • Student attends law school relying on the promise; incurs substantial debt.
  • Estate refuses to pay, asserting gratuitous promise defense.
  • Elements met: promise, reasonable inducement, action, detriment.
  • Outcome: potential recovery under promissory estoppel in equity.

Key Terms & Definitions

  • Consideration: Bargained-for exchange forming a binding legal contract.
  • Gratuitous promise (gift promise): Promise without consideration; not enforceable at law.
  • Promissory estoppel: Equitable doctrine enforcing promises with reasonable, detrimental reliance; also called detrimental reliance.
  • Detriment: Harm or liability incurred due to reliance on a promise.
  • Forbearance: Refraining from action because of a promise.

Action Items / Next Steps

  • Identify promises lacking consideration but inducing reliance.
  • Assess reasonableness and detriment of the reliance.
  • Evaluate equitable remedies when legal contract claims fail.
