Legal Obligations in Contracts: Enforceability and Scope

Every day, we make promises. You tell a friend you will meet them for coffee. You tell your parents you will be home by nine. You tell a client you will deliver a project by Friday. All three are promises, but only one of them will land you in court if you break it. The difference lies in a single idea that sits at the heart of contract law: legal obligation. Understanding what turns an ordinary promise into a legally enforceable one is the first real step toward understanding contracts, and it is exactly what this post breaks down.

What separates an agreement from a contract 🔗

Under the Indian Contract Act, 1872, an agreement is simply “every promise and every set of promises, forming the consideration for each other.” That is a fairly loose definition. It covers dinner plans, favours between friends, and business deals alike. A contract, however, is defined more narrowly as an agreement enforceable by law, a distinction you can verify directly in the official text of the Act.

This means every contract is an agreement, but every agreement is not a contract. The extra ingredient that promotes an agreement into a contract is enforceability, and enforceability depends heavily on whether the parties intended their promise to carry legal consequences. As one legal explainer puts it, an agreement has a wider scope because it covers all promises, while a contract has a narrower scope limited to agreements that satisfy legal requirements.

So the real question for any B.Com student trying to spot a contract is not “did the parties promise something?” but “did they intend for that promise to be legally binding, and does the law recognise it as such?”

Why intention to be legally bound matters so much 🔗

Two people can shake hands on something and still not have a contract. Intention is what separates a casual understanding from a legal obligation. This principle did not originate in India; it was famously established in English law through Balfour v Balfour (1919), a case still taught in Indian classrooms because Indian courts follow the same reasoning.

In that case, a husband promised to pay his wife a monthly allowance while she stayed behind in England for health reasons. When he later stopped the payments, she sued. The court ruled against her, holding that domestic arrangements between spouses are presumed not to carry an intention to create legal relations, since the doctrine of intention to create legal relations distinguishes social or domestic arrangements, where legal consequences are not usually intended, from commercial agreements, where legal enforceability is presumed.

Social, moral, and religious promises: agreement without obligation 🔗

This is why a promise to attend a friend’s wedding, a commitment to donate to a religious cause, or an assurance to help a relative move house does not create a contract, even though a genuine agreement exists. There is a full promise and even consideration in some cases, but no legal duty is intended. If the promisor backs out, the promisee has no remedy in a court of law, because the obligation, if any, is moral, not legal.

Compare this with a supplier who promises to deliver raw materials to a factory by a fixed date. If the supplier defaults, the factory owner can sue for damages or demand performance, because a business promise like this is treated very differently.

Comparing the two categories 🔗

Business agreements and the presumption of legal intent 🔗

In commerce, the default assumption flips. When two businesses, or a business and a customer, enter into an agreement, the law presumes they intended to be legally bound. Nobody signs a purchase order, a lease deed, or a service contract expecting it to be unenforceable. This presumption matters practically, because it shifts the burden of proof: if a business wants to argue that a particular clause was never meant to be binding, it has to show clear evidence of that intention, rather than the other party having to prove the opposite.

This is also why breach of a business agreement is legally actionable in a way that breach of a family promise is not. If a vendor fails to deliver goods as agreed, the buyer can approach a court for remedies such as damages, specific performance, or rescission of the contract. The legal obligation created by the agreement is what gives the buyer that recourse.

Of course, intention alone does not make a contract valid. The agreement still needs the other essentials: free consent, lawful consideration, competent parties, and a lawful object. But intention to create a legal obligation is the gateway condition. Without it, none of the other essentials matter, because there is nothing for a court to enforce in the first place.

Not every enforceable obligation comes from a contract 🔗

Here is where students often get confused: enforceability by law and contract are not the same thing. A contract is one specific source of legal obligation, but it is not the only one. Some obligations are enforceable in court even though there was never an agreement between the parties at all.

Two common examples illustrate this clearly.

Obligations arising from wrongful acts 🔗

If someone damages your property or injures you through negligence, you can claim compensation. This obligation to pay damages arises from a civil wrong, commonly called a tort, not from any agreement between you and the wrongdoer. You never promised each other anything, yet the law still creates a duty and a corresponding right to compensation.

Obligations arising from court decrees and judgments 🔗

Once a court passes a judgment or decree, the losing party is legally bound to comply, whether that means paying a sum of money, handing over property, or performing some other act. This obligation flows from the authority of the court, not from a fresh agreement between the parties. It is enforceable, but it is not contractual in origin.

Quasi-contracts: obligations the law imposes to prevent unfairness 🔗

A subtler category sits between these two. Sections 68 to 72 of the Indian Contract Act describe situations often called quasi-contracts, where there is no real agreement, yet the law imposes an obligation to prevent one party from being unfairly enriched at another’s expense. As one legal resource explains, these obligations do not originate in an agreement, unlike the obligation not to harm another person’s property, judgments of courts, or quasi-contractual duties, yet they remain enforceable in a court of law.

A classic illustration: if you accidentally leave your umbrella at a friend’s shop and they use it without your permission, they owe you compensation for that use, even though neither of you ever agreed to any terms about the umbrella. Similarly, if a trader supplies essential goods to a person who is legally incapable of contracting, such as a minor, the trader can still recover payment from that person’s property. This body of obligations is built on the principle of unjust enrichment, and as one judiciary-exam resource summarises, these are obligations that arise not from any agreement between parties but from principles of natural justice and equity.

So when you are trying to decide whether something is a contract, ask a second question after checking for legal intention: did this obligation arise from an actual agreement between the parties? If the answer is no, and the obligation instead comes from a wrongful act, a court order, or a quasi-contractual situation, it is enforceable law, but it is not, strictly speaking, a contract.

Putting it together: agreement is the genus, contract is the species 🔗

A useful way to remember all of this is to think of “agreement” as the broader category and “contract” as a specific type within it. Every contract begins life as an agreement, but it only earns the status of a contract once two conditions are met together: the parties intended to create a legal obligation, and that obligation genuinely arises out of their agreement rather than from some other legal source like tort or a court decree.

This distinction is not just academic. It decides whether you can walk into a court and demand a remedy, or whether you are left relying on goodwill. For anyone studying business law, it is the foundation on which every later topic, offer, acceptance, consideration, and breach, is built.

What do you think? If a friend promises to invest a fixed sum in your startup and later backs out with no written terms exchanged, do you think a court would treat that as a business promise carrying legal intent, or a social promise that falls outside contract law? And where would you draw the line between a genuine business favour and a legally binding commitment?
