Express vs Implied Contracts: Understanding The Key Differences

Contracts shape everyday transactions, from your lease to that overpriced subscription you forgot to cancel. Some, like express contracts, are clear and written. Others, like implied contracts, rely on actions and expectations, making them harder to enforce.

Just ask Taylor Swift. When her masters were sold without her consent, her express contract let her re-record her albums, reclaiming control. Without that clause, she might have had no legal ground.

Now, imagine that same situation without a written contract. Could Swift have argued her right to re-record based on past practice alone? Probably not. This highlights the importance of knowing when to document terms and when actions might suffice.

This blog post breaks it all down: how express and implied contracts work, when each applies, and how to avoid costly misunderstandings.

What is an Express Contract?

An express contract is a legally binding agreement where all terms are clearly stated, either in writing or verbally. Both parties know exactly what is expected.

Key characteristics of express contracts:

• Clearly defined terms: Responsibilities, timelines, and conditions are explicitly stated
• Legally enforceable: Courts recognize and uphold these agreements
• Common in business: Used in employment, service, and rental agreements

Examples:

• A signed lease agreement that details rent, duration, and tenant obligations
• A written job contract outlining salary, duties, and benefits
• An email agreement where a freelancer and a client confirm payment terms

What is an Implied Contract?

An implied contract is an agreement formed through actions, behavior, or circumstances rather than explicit words or written terms.

Even without a document spelling things out, the law recognizes these contracts based on how people interact. If both sides behave as if an agreement exists, the legal system often treats it that way.

Types of implied contracts

1. Implied-in-fact contract: These contracts come to life through actions rather than written or spoken agreements. For example, If a customer sits in a salon chair and receives a haircut, the salon expects payment, even if no one explicitly discussed the price beforehand. Both parties’ actions indicate an understanding that a service is being provided in exchange for payment.

2. Implied-in-law contract (Quasi contract): This type of contract isn't based on mutual agreement but is imposed by courts to prevent unjust enrichment, when one party unfairly benefits at another’s expense. For instance, a delivery company accidentally drops off goods at the wrong business, and the recipient knowingly uses them without paying. A court may step in and require them to compensate the supplier.

Understanding implied contracts is one thing, but knowing when to rely on them versus when to get everything in writing (express contracts) is what really matters. 

What is the Difference Between Express vs Implied Contracts?

You need to know which contract fits your situation so you don’t run into problems. If the terms aren’t clear upfront, you could end up dealing with disputes or unpaid work. Some agreements should always be written, while others hold up based on actions alone.

Here are the differences between express and implied contracts:

Now that you know the difference between express and implied contracts, the real question is: when should you use each? Pick the wrong one, and you could end up in a legal gray area, or worse, in court.

When Should you Use Express vs Implied Contracts?

Some deals need everything in writing. Others work just fine with a handshake and a mutual understanding. The trick is knowing when to use implied contract vs express contract, so you don’t end up arguing over what was "obviously implied."

Some deals need everything in writing. Others work just fine with a handshake and a mutual understanding. The trick is knowing when to use implied contract vs express contract, so you don’t end up arguing over what was "obviously implied."

Use an express contract when:

1. You need clear, documented terms to avoid disputes

If there’s any chance of confusion, put it in writing. Express contracts eliminate the risk of “Wait, that’s not what I agreed to” moments.

Consider the case of Interbank Investments, LLC v. Eagle River Water and Sanitation District. Interbank Investments entered into a clear, written agreement with Eagle River for specific services. When a dispute arose, the court upheld the express contract, preventing Eagle River from claiming unjust enrichment.

2. The agreement involves significant financial obligations

Big-ticket items like property purchases, business deals, or long-term employment contracts need the clarity and security of a written contract.

3. Compliance requires a written agreement

Some transactions, like real estate deals or government contracts, legally require written documentation. An express contract keeps you on the right side of the law.

Use an implied contract when:

1. The agreement naturally forms through conduct or repeated transactions

Sometimes, actions speak louder than words. If both parties consistently act in a way that shows mutual understanding, an implied contract does the trick.

For instance, consider a local café you visit every morning. Each day, you order a coffee, and upon receiving your drink, you immediately pay for it. Although there is no written agreement stating that you will purchase coffee each day, your consistent actions (ordering and paying) establish an implied contract between you and the café. 

This contract suggests that the café agrees to serve you coffee in exchange for payment each visit. This mutual expectation forms the basis of your daily transaction.

2. The relationship is informal but still legally enforceable

Implied contracts can also arise in less structured, informal interactions where the legal enforceability comes from the parties’ reliance on and trust in one another's promises or indications.

This principle is often referred to as "promissory estoppel" in legal terms.

Consider the case of Hoffman v. Red Owl Stores, Inc. (1965): Hoffman claimed that Red Owl Stores had promised to support him in establishing a franchise. Based on this promise, Hoffman sold his bakery and incurred other costs. However, Red Owl did not follow through on their promise. The court ruled in favor of Hoffman, finding that Red Owl's promises led Hoffman to incur substantial losses based on their reliance.

3. A written contract isn’t practical, but obligations are clear through actions

Sometimes, time is tight, or the situation doesn’t call for paperwork. That doesn’t mean there’s no contract; implied agreements ensure fairness based on standard business practices.

For instance, in the case of Contamv. Wisdom, the doctor saved an unconscious patient’s life, no questions asked. The patient woke up, fully recovered, but refused to pay the medical bill, arguing that there was no agreement. The court ruled that the doctor’s actions, providing emergency care, and the patient’s acceptance created an implied contract. The decision was based on fairness (preventing the patient from getting a free ride) and industry standards (doctors don’t work for free).

Are Implied Contracts as Strong as Express Contracts?

If express contracts are a locked-in dinner reservation, implied contracts are more like showing up at your usual diner, expecting your favorite booth to be available. One guarantees you a seat. The other? Well, it depends on how well the staff knows you.

So no, implied contracts are not as strong as express contracts. 

Express contracts win legal battles because they spell everything out—who owes what, when, and how. Implied contracts rely on mutual understanding and past behavior. When a dispute arises, proving intent is a lot harder without something in writing.

Why express contracts are easier to enforce:

• Clearly defined terms: Everything is spelled out upfront, reducing misunderstandings
• Easier burden of proof: If things go south, a written or recorded agreement serves as direct evidence
• Regulatory compliance: Some contracts (real estate, intellectual property, large business deals) must be in writing to be legally valid. No document, no case

Challenges of enforcing implied contracts:

• Blurred lines: Without written terms, both sides may have very different ideas about the deal
• Reliance on circumstantial evidence: Courts often examine past interactions, industry norms, and fairness principles to determine whether a contract existed
• Higher risk of disputes: Without a documented agreement, misunderstandings can quickly turn into costly legal battles
