Law of Contract — Essentials of a Valid Agreement

What turns a conversation into a promise the law will enforce, and what happens when a promise is broken.

Educational notes · Last reviewed June 2026

Most commercial disputes reduce to two questions: was there a contract, and what did it require? Both are answered by returning to the essentials of a valid agreement.

These notes set out those essentials, the categories of agreements the law refuses to enforce, and the remedies available on breach.

Contents

  1. Offer, acceptance and communication
  2. Consideration
  3. Capacity to contract
  4. Free consent: coercion, undue influence, fraud, misrepresentation, mistake
  5. Lawful object and void agreements
  6. Performance and discharge
  7. Breach and remedies

Key concepts

Consideration
Something of value given in return for a promise. An agreement without consideration is, as a rule, void.
Free consent
Consent not caused by coercion, undue influence, fraud, misrepresentation or mistake; its absence usually makes the contract voidable.
Void and voidable
A void agreement has no legal effect at all; a voidable contract is valid until the affected party elects to set it aside.
Damages
Compensation for loss naturally arising from the breach; remote or speculative loss is not recoverable.
Specific performance
A direction to perform the contract itself, granted in the discretion of the court where damages are inadequate.

Topics covered

  • Formation of a binding agreement
  • Vitiating factors affecting consent
  • Agreements declared void by statute
  • Measure of damages on breach
  • When specific performance is granted
