Introduction to Contract
Did you know that over 90% of business conflicts in India result from contract issues? Therefore, all business people and professionals must know about different types of contracts. These legally enforceable contracts are the pillars of business relations.
In India, all contracts are governed by the rules of the Indian Contract Act of 1872 (yes, it’s quite old, but still active!). The clear understanding of contracts prevent problems, build trust, and save time that would otherwise be wasted fixing avoidable mistakes.
What is a Contract in Business Law?
A contract in business law means a voluntary, lawful agreement between two or more parties that creates binding obligations enforceable by a court.
Different types of contracts vary based on formation, performance timing, and enforceability. Every valid contract requires an offer, acceptance, consideration, capacity, and lawful intent.
Differences between Agreement and Contract
Many people use the terms agreement and contract interchangeably. However, they have distinct meanings in business law.

Essentials of a Valid Contract
For any contract to be legally binding, it must contain certain essential elements:
- Offer and Acceptance: One party must make a definite proposal that another accepts.
- Lawful Consideration: Something of value must be exchanged between parties.
- Capacity to Contract: All parties must be legally competent to enter into agreements.
- Free Consent: Agreement must be made without coercion or fraud.
- Lawful Object: The purpose of the agreement must not be illegal or immoral.
- Certainty of Terms: Contract provisions must be clear and unambiguous.
Capacity to Contract in Business Law
The capacity to contract in business law refers to a person’s legal ability to enter binding agreements. Here’s who can and cannot form valid contracts:
- Minors (under 18 years): Cannot enter into valid contracts.
- Persons of unsound mind: Limited contractual capacity depending on mental state.
- Intoxicated persons: Heavily intoxicated individuals may void their contracts.
- Corporations: Can only contract through authorized representatives.
- Disqualified persons: Those legally barred from certain agreements.
- Foreign nationals: Prohibited from entering into certain contract types, like lottery and gambling businesses, atomic energy, and tobacco products.
Types of Contracts in Business Law Based on Different Criteria
Business law recognizes several types of contracts based on different classification criteria:
Formation
- Express Contracts: Parties explicitly state all terms, either verbally or in writing. Example: A and B sign a written agreement for A to deliver goods.
- Implied Contracts: Terms are inferred from conduct rather than words. Example: A eats at B’s cafe; the law implies A must pay.
- Quasi Contracts: A quasi-contract is not a true contract but a legal obligation created by courts. It prevents unjust enrichment when no formal agreement exists. Example: A mistakenly pays B ₹10,000; the court orders B to return it.
Execution Timing
- Executed Contracts: Parties have completed all obligations immediately. Example: A pays B Rs 200 for a cup of tea; both parties complete their duties immediately.
- Executory Contracts: Some or all obligations remain to be fulfilled in the future. Example: A agrees to build B’s website next month; work remains pending.
- Partly Executed Contracts: Some obligations are fulfilled while others remain pending. Example: A delivers 50 of B’s 100 ordered chairs; the rest await delivery.
Validity
- Valid Contracts: Fulfill all legal requirements and are fully enforceable. Example: A and B sign a written agreement for A to sell his car to B for Rs. 3 lakhs, and both uphold the terms faithfully.
- Void Contracts: Cannot be enforced by law due to missing essential elements. Example: A promises B to pay Rs 10,000 to bribe a government official; courts regard that promise as void.
- Voidable Contracts: One party can choose whether to enforce or reject the contract. Example: A is a minor who agrees to buy a laptop from B (an adult); A can later void the contract because the law protects minors.
- Unenforceable Contracts: A valid contract that fails to meet formalities, so courts can’t enforce it. Example: A and B orally agree to sell a plot of land; a court won’t enforce it because land transfers must be in writing.
Number of Parties
- Bilateral Contracts: Involve promises from two parties. Most business contracts fall here.
- Unilateral Contracts: Only one party makes a promise. Insurance policies often take this form.
Performance of Contract in Business Law
Performance of the contract here means the parties must perform exactly as they promise, and the types of contracts determine how to evaluate performance.
Indian law recognizes:
- Actual Performance: Complete fulfillment of all obligations.
- Attempted Performance: One party attempts to perform, but the other prevents it.
- Substantial Performance: Most obligations are there to be fulfilled with minor deviations.
Discharge of Different Types of Contracts in Business Law
Discharge means the termination of contractual obligations. Different types of contracts may be discharged through:
- Performance: Both sides complete their promises.
- Agreement (Rescission): Both sides mutually agree to end the contract.
- Frustration (Impossibility): An unforeseen event makes performance impossible.
- Breach: One side deliberately or negligently fails, giving the innocent party the right to terminate.
Remedies for Breach of Contract in Business Law
When contractual obligations are not legally fulfilled, the wronged party can seek remedies:

- Damages: The court makes the person who broke their promise pay you money to cover your losses.
- Specific Performance: The court orders someone to do exactly what they agreed to do.
- Injunction: The court tells someone to stop (or start) a specific action to prevent harm.
- Quantum Meruit: You receive fair payment for work you’ve already completed, even without a formal agreement.
Digital Contracts: Modern Types of Contracts
Technology has introduced new types of contracts in business law:
- Click-wrap Agreements: Users click “I Agree” to accept the terms.
- E-signatures: Digital authentication of contract acceptance.
- Smart Contracts: Self-executing agreements with terms written in code.
Types of Contracts in Different Industries
Industry-specific types of contracts have evolved to address unique business needs:
Manufacturing Sector
Supply agreements, distribution contracts, and quality assurance agreements dominate.
Corporate Industry
Shareholders, Joint ventures, and Investment agreements are quite common.
Service Industry
Service level agreements, confidentiality contracts, and client agreements are common.
Real Estate
Lease agreements, purchase contracts, and development agreements shape this sector.
