1. Discharge of Contract — Meaning and the Six Modes

Every contract that begins must, at some point, come to an end. This post is the roadmap for the rest of Unit 3 — it names the six ways a contract's obligations can be lawfully brought to a close, before we study each one in detail.

The Problem This Topic Solves

So far, this subject has been about how a contract is formed and made valid. But formation is only half the story — every contract, once made, is designed to end. Students often use the word "discharge" loosely, as if it only means "the work got done." In law, it means something more precise: a contract is discharged when the parties' obligations under it cease to exist, for any one of several recognised reasons. Confusing "discharge" with only "performance" causes real problems in exam answers — questions on frustration, breach, or novation are often mis-answered because students try to force every fact pattern into "performance," when the syllabus recognises five other distinct routes to the same result.

What Does "Discharge of Contract" Mean?

Discharge of contract is the termination of the contractual relationship between the parties — the point at which the rights and duties created by the contract come to an end. Section 37 of the Indian Contract Act, 1872 states the starting obligation clearly: the parties to a contract must either perform, or offer to perform, their respective promises, unless such performance is dispensed with or excused under the Act or any other law. Everything in this unit is really an answer to the question: in what situations is a party excused from this obligation, and how does that excuse arise?

The Six Modes of Discharge

Textbook writers on the Indian Contract Act classify discharge into six broad modes. This unit's syllabus focuses on four of them in depth — performance, agreement, impossibility, and breach — but a complete picture needs all six named at the outset:

1. By Performance — each party does exactly what they promised. This is the most common and the "default" way a contract ends. Covered in the next post.
2. By Mutual Agreement — the parties themselves agree to end, replace, or modify the contract, through novation, rescission, alteration, remission, or accord and satisfaction (Sections 62–63).
3. By Impossibility of Performance — an event after the contract is made makes performance impossible or unlawful, so the law itself excuses the parties. Also called the Doctrine of Frustration (Section 56).
4. By Lapse of Time — where a contract fixes a time for performance and that time passes without performance, or where the Limitation Act, 1963 bars a remedy after a fixed period. This is studied in detail as part of the Limitation Act, not repeated here.
5. By Operation of Law — discharge that happens automatically, without either party's choice — for example, by the death of a party in a contract requiring personal skill, by the merger of a lower contract into a higher one, or by insolvency.
6. By Breach — one party fails or refuses to perform, giving the other party the option to treat the contract as discharged and claim a remedy.

Modes 4 and 5 are mentioned here only for completeness — this unit does not dedicate separate posts to them, since lapse of time belongs properly to the Limitation Act and operation-of-law situations are narrow and largely covered incidentally within the impossibility and performance posts.

Six Modes at a Glance

• Section 37 — the basic obligation to perform or offer to perform
• The six modes of discharge, and which four this unit covers in depth: performance, agreement, impossibility, and breach
• "Discharge" is broader than "performance" — a contract can end validly without either party ever performing it (e.g., by frustration or by mutual rescission)

A Practical Example

A catering company signs a contract to supply food for a wedding on a fixed date. There are several ways this contract could end: the company could simply deliver the food as promised (performance); the couple and the company could agree beforehand to cancel the booking (agreement); the wedding venue could burn down before the date, making specific performance impossible (impossibility); or the company could simply fail to show up on the day (breach). Each of these is a different "mode" of discharge, and each has different legal consequences — which is exactly why this unit studies them separately.

Quick Revision Points

• Discharge = termination of the contractual relationship, for any recognised legal reason
• Section 37 states the core obligation to perform or offer to perform
• Six modes: performance, agreement, impossibility, lapse of time, operation of law, breach
• This unit builds four full posts around performance, agreement, impossibility, and breach — in that order
