Quasi Contracts & Unjust Enrichment Explained | Indian Contract Act 1872

📝 Laws Relating to Certain Relations Resembling Those Created by Contract

💼 With Special Emphasis on Unjust Enrichment (Detailed Explanation)

⚖️ Meaning of Quasi Contract

---

🔍 Introduction

In legal systems, most obligations arise from contracts, where parties voluntarily agree to perform certain duties. However, there are situations where no agreement exists, yet one party is legally required to compensate another.

Such obligations are covered under “relations resembling those created by contract”, commonly known as quasi-contracts, under Sections 68 to 72 of the Indian Contract Act, 1872.

👉 The primary aim of these provisions is to ensure justice, equity, and fairness, mainly through the doctrine of unjust enrichment.

---

⚖️ Meaning of Quasi Contract

A quasi-contract is not an actual contract because:

• There is no offer and acceptance
• There is no mutual consent
• There is no intention to create legal relations

Yet, the law imposes an obligation as if a contract exists.

👉 Definition (Simple):
A quasi-contract is a legal obligation created by law to prevent one person from being unjustly enriched at the expense of another.

💡 Doctrine of Unjust Enrichment

📌 Meaning

Unjust enrichment refers to a situation where:

One person gains a benefit unfairly, and the law requires them to return or compensate for that benefit.

---

⚖️ Essential Elements

To establish unjust enrichment, the following must be present:

1️⃣ Enrichment – One person has received a benefit
2️⃣ At the expense of another – Another person has suffered loss
3️⃣ Unjust nature – The benefit is unfair or without legal justification

---

📊 Example

If ₹20,000 is mistakenly transferred to someone’s account, the receiver must return it.
