What is the main difference between an agreement and a contract?

Enforceability. An agreement is any mutual understanding between parties. A contract is an agreement the law will enforce, because it has consideration, an intention to create legal relations, parties with capacity, free consent and a lawful object. Every contract is an agreement, but not every agreement is a contract.

Is every agreement a contract?

No. Social and domestic arrangements, agreements without consideration (in common law), agreements with minors, wagering agreements and agreements that are too vague are agreements but not contracts. Only agreements that meet all the legal requirements are contracts.

How does the Indian Contract Act define agreement and contract?

Section 2(e) defines an agreement as “every promise and every set of promises, forming the consideration for each other”. Section 2(h) defines a contract as “an agreement enforceable by law”. Section 10 lists what makes an agreement enforceable: free consent of competent parties, lawful consideration and a lawful object, and not being expressly declared void.

Is an agreement legally binding?

Only if it meets the requirements of a contract. A written agreement signed by two businesses that exchange goods or services for payment almost always is. A casual promise between friends usually is not, because there is no intention to create legal relations.

Can a verbal agreement be a contract?

Yes. An oral agreement with all the elements of a contract is binding in most cases. Some contracts must be in writing, such as contracts for the sale of land, and oral contracts are always harder to prove. Put anything important in writing.

What is a void agreement?

An agreement that the law will not enforce at all, from the start. Under the Indian Contract Act, examples include agreements without consideration, agreements in restraint of trade or marriage, wagering agreements and agreements whose meaning is uncertain. An agreement with an unlawful object is void everywhere.

Is an MOU an agreement or a contract?

An MOU is an agreement and is usually not a contract, because the parties state that it is not legally binding. Individual clauses such as confidentiality or exclusivity are often meant to bind. If an MOU reads like a contract and the parties act on it, a court may treat it as one.

Should I call my document an agreement or a contract?

It makes no legal difference. Many binding contracts are titled “agreement”, such as a service agreement or a loan agreement. What matters is the content: clear terms, consideration, intention to be bound, capacity and the right form.

Difference between agreement and contract, with examples

“Agreement” and “contract” are often used as if they meant the same thing, and in a business document title they usually do. In law they do not. The difference decides whether you can go to court when the other side breaks its word.

The short answer

Every contract is an agreement, but not every agreement is a contract.

An agreement is any meeting of minds between two or more parties. It becomes a contract only when the law will enforce it. In common law countries that takes an offer and acceptance, consideration, an intention to create legal relations, parties with capacity, free consent and a lawful purpose.

The Indian Contract Act 1872 says it in one line: “An agreement enforceable by law is a contract” (section 2(h)).

Agreement: A mutual understanding between two or more parties about what each will do or not do. It can be spoken, written or shown by conduct. An agreement may be legally binding, but it does not have to be: a promise to help a friend move house is an agreement, not a contract.

Contract: An agreement that the law will enforce. It sets out obligations the parties owe each other, and if one side fails to perform, the other can claim damages or, in some cases, ask a court to order performance.

Agreement vs contract: comparison table

	Agreement	Contract
Definition	Any mutual understanding between parties	An agreement enforceable by law
Scope	Wider: includes social, domestic and informal arrangements	Narrower: a subset of agreements
Legal effect	May or may not be binding	Always legally binding (unless void or voidable)
Required elements	Offer and acceptance, a meeting of minds	Offer and acceptance plus consideration, intention to create legal relations, capacity, free consent, lawful object
Form	Any: spoken, written, by conduct	Usually any form, but some contracts must be in writing or registered
If it is broken	No legal remedy, only social or commercial consequences	Damages, specific performance or other court remedies
Indian Contract Act 1872	Section 2(e)	Section 2(h)
Example	Agreeing to meet a friend for dinner	A signed service agreement with a supplier

The elements that turn an agreement into a contract

An agreement becomes a contract when it has all of the following. Miss one and you have an agreement the law will not enforce, or a contract that can be cancelled.

Element	What it means	If it is missing
Offer	One party proposes clear terms	No agreement at all
Acceptance	The other party agrees to those exact terms	A counter-offer, not acceptance
Consideration	Each side gives something of value: money, goods, services or a promise	In common law, a bare promise (a gift) is generally not enforceable
Intention to create legal relations	The parties mean to be legally bound	A social or domestic arrangement
Capacity	Both parties are legally able to contract: adults of sound mind, companies acting through authorised people	The agreement may be void or voidable
Free consent and lawful object	Nobody was coerced, defrauded or misled, and the purpose is legal	Voidable (no free consent) or void (unlawful object)

Courts also expect the terms to be certain enough to enforce. An agreement to agree “a fair price later” is usually too vague.

Consideration is a common law idea. Civil law systems such as Germany and France do not require it, so a promise to give a gift can be a valid contract there, although German law requires a gift promise to be notarised (section 518 BGB). For a deeper look at each requirement, see what makes a contract enforceable.

Agreement and contract under the Indian Contract Act, 1872

Indian law spells out the difference more clearly than most legal systems, because the Indian Contract Act 1872 defines both words. Section 2 builds a contract in steps:

Proposal (s. 2(a)): one person signals to another a willingness to do or not do something, to obtain the other’s assent.
Promise (s. 2(b)): “A proposal, when accepted, becomes a promise.”
Agreement (s. 2(e)): “Every promise and every set of promises, forming the consideration for each other, is an agreement.”
Contract (s. 2(h)): “An agreement enforceable by law is a contract.”

Section 2(g) completes the picture: “An agreement not enforceable by law is said to be void.” A voidable contract (s. 2(i)) is one enforceable at the option of one party but not the other, for example a contract signed under coercion.

What makes an agreement enforceable is set out in section 10: “All agreements are contracts if they are made by the free consent of parties competent to contract, for a lawful consideration and with a lawful object, and are not hereby expressly declared to be void.”

The Act then lists agreements it declares void, even if the parties meant them seriously:

Section	Agreement declared void
s. 25	Agreements without consideration, with narrow exceptions (for example, a written and registered promise made out of natural love and affection)
s. 26	Agreements in restraint of marriage
s. 27	Agreements in restraint of trade, which is why Indian courts generally do not enforce post-employment non-compete clauses
s. 28	Agreements in restraint of legal proceedings
s. 29	Agreements whose meaning is uncertain
s. 30	Wagering agreements

Capacity is covered in section 11: a person must be of the age of majority, of sound mind and not disqualified by law. In Mohori Bibee v Dharmodas Ghose (1903), the Privy Council held that an agreement with a minor is void from the start.

Examples of agreements that are not contracts

Example	Why it is not a contract
You promise to water a neighbour’s plants while they are away	Social arrangement, no intention to create legal relations
A husband promises his wife a monthly allowance	Domestic arrangement. In Balfour v Balfour (1919) the English Court of Appeal refused to enforce it
A 16-year-old borrows money against a signed note	The minor lacks capacity, so under Indian law the agreement is void
You promise to give a friend your old laptop for nothing	No consideration (in common law systems)
Two people bet on the result of a cricket match	Wagering agreement, void under s. 30 in India and unenforceable in many other countries
Two companies agree to “share profits in a fair way to be agreed”	Too uncertain to enforce
A gentlemen’s agreement “binding in honour only”	The parties have expressly excluded legal effect

And agreements that are contracts: an employment contract, a sale of goods contract, a lease, a non-disclosure agreement or a service agreement with a supplier. Most of them are called “agreements” on the cover page. The title does not matter: what makes them contracts is that they meet the requirements above. Our overview of the 15 most common types of contracts covers each in turn.

The grey zone: MOUs, letters of intent and term sheets

Some documents sit between a plain agreement and a full contract. They record a deal in principle while the real contract is negotiated.

Memorandum of understanding (MOU): sets out a shared plan, often for a partnership or cooperation. Usually non-binding. See our MOU template.
Letter of intent (LOI): records the main terms of a planned transaction such as an acquisition. Usually non-binding on the deal itself. See our letter of intent template.
Heads of terms and term sheets: a short list of agreed commercial points, common in property and investment deals. See the heads of terms template.

These documents usually mix the two. The commercial terms are expressly non-binding, but certain clauses are meant to bind straight away: confidentiality, exclusivity, costs and governing law. A court looks at the wording and at how the parties behaved, so a document headed “non-binding” can still create obligations if it reads and works like a contract. State in the document itself which clauses bind and which do not. Words such as “subject to contract” signal that no contract exists until the final document is signed.

Does an agreement have to be in writing to be a contract?

Usually not. An oral agreement that meets all the elements is a binding contract in most legal systems, though it is much harder to prove. Some contracts are exceptions:

United States: under the statute of frauds, most states require a signed writing for contracts for the sale of land, contracts that cannot be performed within one year, promises to pay another person’s debt, and sales of goods for $500 or more.
United Kingdom: contracts for the sale of land must be in writing and signed by both parties (Law of Property (Miscellaneous Provisions) Act 1989, section 2).
India: section 10 of the Contract Act keeps in force any law that requires a contract to be written, witnessed or registered, for example the registration requirements for certain property documents under the Registration Act 1908.

Writing it down is the safer choice in every case. A written contract shows who agreed to what, and a signed one is easy to produce in a dispute.

Contract or agreement: which word should you use?

For the document title, either is fine. “Service agreement”, “employment contract” and “loan agreement” are all contracts if they meet the requirements. Lawyers in common law countries often prefer “agreement” in titles, and the choice of word has no legal effect.

The distinction matters when you are relying on someone’s word. If you need to be able to enforce it, make sure it is a contract: clear terms, something exchanged on both sides, the intention to be bound, signatures from people with authority, and the form the law requires.
