PRACTICE NOTES

1. Quasi-Contract Nature: Unjust enrichment is a quasi-contract or implied-in-law contract - obligation imposed by law, not by agreement. It is an equitable remedy.

2. Express Contract Bar: In most jurisdictions, unjust enrichment cannot be recovered where a valid express contract governs the same subject matter. Plead in the alternative if contract validity is disputed.

3. Unjust Enrichment vs. Quantum Meruit: Quantum meruit is based on the reasonable value of services rendered; unjust enrichment focuses on the defendant's enrichment. Damages may differ.

4. Officious Intermeddler Doctrine: A person who confers benefits officiously (voluntarily, without request) cannot recover under unjust enrichment. Show that defendant requested or knew of benefits.

5. Valuation: Unjust enrichment is typically measured by the defendant's gain, while quantum meruit is measured by the reasonable value of plaintiff's services. Know which measure applies.

6. Constructive Trust: Where defendant holds specific property, seek imposition of a constructive trust rather than (or in addition to) money damages.

7. Good Faith: Some jurisdictions require that plaintiff acted in good faith in conferring the benefit.

8. Wrongful Conduct: Some jurisdictions (like Texas) require some element of wrongful conduct beyond mere failure to pay.

9. Accounting: In complex cases involving ongoing relationships, seek an accounting to determine exact amounts owed.

10. Equitable Defenses: Defendant may raise equitable defenses such as laches, unclean hands, or estoppel. Be prepared to address these.
