Unjust Enrichment Claims Under Singapore Law
⚖️ Concept of Unjust Enrichment
Under Singapore law, a claim for unjust enrichment requires the claimant to prove four elements:
- Enrichment of the Defendant – The defendant must have received a benefit.
- At the Expense of the Claimant – There must be a direct link between enrichment and the claimant.
- Unjust Factor – A recognized reason that makes retention of the benefit inequitable, e.g., mistake, duress, failure of consideration.
- Absence of Defenses – Defendant may rely on defenses like change of position.
This framework is derived from English common law and applied consistently in Singapore cases.
🧩 Types of “Unjust Factors”
- Mistake of fact or law – Payment made under a false assumption
- Failure of consideration – Prepayment for goods or services not delivered
- Duress or undue influence – Consent obtained unfairly
- Illegality – Recovery in certain illegal transactions
- Statutory obligations – Where law imposes restitution
