Quasi Contract: Meaning, Types, Examples, and How It Works
What happens when a business receives goods or services without signing a contract? Can the supplier still ask for payment? In some cases, the law may require the receiving party to pay, even when no formal deal exists.
- Prevent unfair gains: It may require a company to pay for a benefit it knowingly keeps, even without a signed deal.
- Understand legal requirements: Courts look at the value received, the circumstances, and whether keeping that benefit without payment would be unfair.
- Know the differences: Express and implied contracts come from mutual agreement, while quasi contracts arise through legal action to prevent unjust enrichment.
- Reduce business risks: Clear purchase records, delivery checks, written communication, and tools help companies avoid unexpected payment claims.
This is where a quasi contract comes into play.
Businesses often work with suppliers, manufacturers, and service providers. Sometimes, a company receives a benefit due to a delivery mistake, an urgent repair, or work completed without a clear agreement.
In this blog, we will explain how quasi agreements work, their main elements, common types, examples, and practical ways businesses can reduce related risks.
What Is a Quasi Contract?
A quasi contract is a legal remedy that allows a court to require one party to compensate another for a benefit received unfairly. It applies when no enforceable agreement covers the situation, but allowing one side to keep the benefit without payment would be unjust.
Unlike a traditional contract, a constructive contract does not depend on an offer, contract acceptance, or a shared promise. Instead, the court may impose a duty to pay based on the facts of the case.
For example, suppose a supplier accidentally sends valuable machine parts to the wrong factory. The factory discovers the mistake but uses the parts in production. If the supplier cannot recover them.
How Does a Quasi Contract Work?
It works through a legal claim rather than a normal business deal. When one party receives a valuable benefit without a valid agreement, the other party may ask a court for compensation. Here is how the process generally works.
Step 1: One Party Provides Something Valuable
A business supplies materials, completes work, or provides a service that benefits another company.
Step 2: No Enforceable Contract Covers the Situation
The parties may not have reached an agreement, or an existing contract may not cover the specific transaction.
Step 3: The Receiving Party Gains a Benefit
The receiving party accepts, uses, or retains something of measurable value.
Step 4: The Provider Requests Compensation
The supplier asks for payment or the return of the property. If the issue remains unresolved, the supplier may pursue a legal claim.
Step 5: The Court Examines the Circumstances
The circumstances are assessed to determine whether the receiving party has a contractual obligation to compensate the provider for the benefit received.
Step 6: The Court May Order Repayment
If the legal requirements are met, the receiving party may have to repay the amount owed, compensate the provider, or return the property, depending on the applicable law.
However, receiving something valuable does not automatically create a constructive-contract. The outcome depends on the facts and the applicable law.
What Is the Purpose of a Quasi Contract?
The main purpose of a quasi-agreement is to prevent one party from gaining unfairly at another party’s expense. It provides a possible solution when ordinary contract law does not offer a way to recover the value of goods or services.
The constructive contract promotes fair financial dealings by recognizing situations where a business receives valuable goods or services without making the appropriate payment. For example, if a manufacturing company knowingly uses raw materials delivered by mistake, it may be required to compensate the supplier.
A quasi agreement provides businesses with a potential way to recover reasonable compensation for goods supplied or services performed when the applicable legal requirements are satisfied.
A constructive contract encourage businesses to act responsibly when receiving goods, services, or payments they were not entitled to retain without compensation. For example, when a company receives an incorrect shipment, notifying the supplier and arranging its return or appropriate payment can reduce contract disputes.
Unlike an express contract, which is formed through clearly communicated agreement between parties, a quasi-contract creates an obligation imposed by law when the applicable conditions are satisfied. This allows an eligible party to seek compensation even when the parties have not mutually agreed to the obligation.
This Quasi contract provides a legal framework for resolving certain situations involving emergency services, mistaken deliveries, or benefits received under an unenforceable arrangement. Depending on the circumstance, the service provider may be entitled to reasonable compensation despite the absence of an agreed contract.

What are the Essential Elements of a Quasi Contract?
It applies to different situations where one party receives an unfair benefit at another’s expense, such as mistaken payments, unexpected goods, or services provided without a formal agreement.
Quantum meruit refers to recovering the reasonable value of services provided. Quasi agreement may apply when a person performs work that benefits another party, but no enforceable agreement determines the payment owed.
Quantum valebant is a traditional legal term for recovering the reasonable value of goods supplied. It relates to situations where a party provides goods and seeks payment for their contract value. Modern claims may fall under restitution or applicable commercial laws.
This claim involves recovering money transferred or paid by mistake. When a recipient receives money they are not legally entitled to retain, the sender may seek repayment under applicable restitution principles.
A person who provides necessary services or benefits during an emergency may be entitled to compensation in certain circumstances. The availability of a claim depends on the nature of the emergency, the benefit provided, and the applicable legal requirements.
When an quasi agreement is invalid or unenforceable, one party may have already provided goods, services, or money to the other. Depending on the reason the agreement is unenforceable, restitution may allow the provider to recover the value of the benefit transferred.
These categories may overlap, and the availability of each claim depends on the applicable law and the circumstances of the case.
What are Some Examples of Quasi Contracts?
Manufacturing businesses handle large quantities of goods, machinery, and outside services. These activities can create situations where one company receives value without a valid agreement.
1. Manufacturing Industry
A steel manufacturer accidentally delivers $25,000 worth of steel sheets to the wrong factory. The factory uses the materials to fulfill a customer order before discovering the delivery error. The original supplier may seek compensation for the materials, depending on the circumstances and applicable law.
2. IT and Software Industry
An IT consulting firm provides $12,000 worth of emergency server recovery services to a company experiencing a critical system failure. The company accepts the services, but no enforceable agreement covers the payment. Depending on the circumstances, the consulting firm may seek reasonable compensation for the benefit provided.
Difference Between a Quasi Contract, Express Contract, and an Implied Contract?
The main difference lies in how the legal relationship begins. An express contract comes from clearly stated promises. An implied-in-fact contract arises from actions that show mutual agreement. It comes from the law to prevent an unfair benefit.
Aspect | Quasi contract | Express contract | Implied-in-fact contract |
Formation | Created by law to provide a solution. | Created through spoken or written promises | Created through conduct |
Mutual consent | Not required | Required | Required, but shown through actions |
Written document | Not necessary | May be written or oral | Usually not necessary |
Legal basis | Unjust enrichment | Mutual agreement | Conduct showing agreement |
Main purpose | Prevent unfair gains | Carry out agreed promises | Enforce a deal shown by behaviour |
Payment | Based on the applicable restitution measure | Based on the agreed price | Based on what the parties’ actions establish |
The key distinction: An implied-in-fact contract is a real agreement proven through behaviors. A quasi contract is not a true agreement, even though its name includes the word “contract.”
Best Practices to Manage Quasi Contracts
According to World Commerce & Contracting, research covering more than 1,200 organizations found an average loss of 8.6% of contract value due to contract management issues. This figure reflects broader contract management challenges, not quasi contract claims specifically.
Here are seven best practices businesses can follow:
- Document Every Business Transaction: Maintain accurate records of purchases, deliveries, repairs, and services. Check unexpected shipments against purchase orders to identify errors early.
- Confirm Work Before It Begins: Obtain written approval for additional services or work. Emails and other documented communications can clarify the scope of work and payment expectations.
- Report Incorrect Deliveries Immediately: Train warehouse employees to identify unexpected shipments and notify suppliers promptly before using the goods.
- Maintain Accurate Payment Records: Review invoices, receipts, and bank transfers to identify duplicate payments or financial errors. Document corrections and communicate them to the relevant parties.
- Maintain a Central Contract Repository: Store contracts, purchase orders, supplier contracts, and related communications in one accessible location so employees can verify the terms governing a transaction.
- Train Employees on Unauthorized Work: Establish clear contract approval process for additional services and purchases, particularly for production, maintenance, and procurement teams.
- Review Unusual Transactions with Legal Teams: Seek legal guidance when a business receives valuable goods or services without clear documentation.
