Section 15 explained: this guide covers what it means, who it applies to, the step-by-step process, documents required, fees, due dates and penalties in India — so you can stay compliant with confidence and avoid costly mistakes.
Section 15 defines coercion. In the Act's words, it is the committing, or threatening to commit, any act forbidden by the Indian Penal Code, or the unlawful detaining, or threatening to detain, any property, to the prejudice of any person whatever, with the intention of causing any person to enter into an agreement.
Coercion is (i) committing, or threatening to commit, any act forbidden by the Indian Penal Code, or (ii) unlawfully detaining, or threatening to detain, any property, to the prejudice of any person whatever, with the intention of causing any person to enter into an agreement. It is immaterial whether the Indian Penal Code is in force in the place where the coercion is used. Where consent is caused by coercion, section 19 makes the agreement voidable at the option of the party whose consent was so caused.
The definition in parts
The section reads: "'Coercion' is the committing, or threatening to commit, any act forbidden by the Indian Penal Code (45 of 1860) or the unlawful detaining, or threatening to detain, any property, to the prejudice of any person whatever, with the intention of causing any person to enter into an agreement."

If you are facing a claim that an agreement was signed under threat, or you want to challenge one, our legal dispute resolution service can help you assess it.
Limb 1: an act forbidden by the Indian Penal Code
The first limb covers committing or threatening any act that the Indian Penal Code forbids. Note the words: "committing, or threatening to commit". A threat is enough; the act need not be carried out.
A note on the statute cited. From 1 July 2024 the Indian Penal Code was replaced by the Bharatiya Nyaya Sanhita. The Contract Act's text still refers to the Indian Penal Code (45 of 1860), and we quote it as it stands.
Limb 2: unlawful detention of property
The second limb is the unlawful detaining, or threatening to detain, any property. The word "unlawful" is part of the text. The section does not say what detention of property is unlawful beyond that word.
"To the prejudice of any person whatever"
The detention or act is "to the prejudice of any person whatever". The person prejudiced need not be the person who signs the agreement. The words are wide.
"With the intention of causing any person to enter into an agreement"
The conduct must be done with that intention. Coercion is therefore not just any wrongful act; it is one done to cause someone to enter into an agreement. Similarly, the definition says "any person" enters into the agreement, not only the person against whom the act is directed.
The Explanation: place does not matter
The Explanation reads: "It is immaterial whether the Indian Penal Code (45 of 1860) is or is not in force in the place where the coercion is employed." So coercion can be found even where the Penal Code did not apply to the act at the place it happened.
The Act's own illustration
A, on board an English ship on the high seas, causes B to enter into an agreement by an act amounting to criminal intimidation under the Indian Penal Code. A afterwards sues B for breach of contract at Calcutta. The Act says A has employed coercion, although his act is not an offence by the law of England and although section 506 of the Indian Penal Code was not in force at the time when or place where the act was done.
This illustration is the Act's own. It shows the Explanation at work: what matters is whether the act amounts to what the Penal Code forbids, not whether the Code applied in the place of the act.
What follows from coercion
Section 15 defines the term; it does not itself state the effect. The consequence is in section 19: "When consent to an agreement is caused by coercion, fraud or misrepresentation, the agreement is a contract voidable at the option of the party whose consent was so caused." The "caused" test comes from section 14: consent is so caused when it would not have been given but for the coercion. See our article on section 14 and on section 19.
| Question | Answer in the text |
|---|---|
| Is a threat enough? | Yes: "committing, or threatening to commit" |
| Is the detention of property covered? | Yes, if unlawful |
| Must the Penal Code be in force at the place? | No (Explanation) |
| Effect on the agreement | Voidable at the option of the party whose consent was so caused (s.19) |
A modern example (ours, not the Act's)
Tushar runs a transport company and holds a customer's goods in his warehouse. He tells the customer, Yashika, that he will not release her stock, which she has paid for, unless she signs a new long-term contract at higher rates. The detention is unlawful because she is entitled to the goods. Tushar's threat to keep detaining her property is aimed at making her enter the agreement. That fits the second limb of section 15. If Yashika signs because of this, the Act's section 19 makes the contract voidable at her option. Whether her facts meet the definition depends on whether the detention was in fact unlawful, which the section leaves to other law.
What can the parties change?
Nothing in section 15 allows parties to agree that coercion will not count. A contract term that says "the parties confirm there was no pressure" does not change what the Act defines as coercion. What parties can do is avoid the conduct, and keep records showing that agreements were negotiated openly.
Practical points
- Do not hold property to force a signature. Threatening to detain someone's property to obtain an agreement falls within the second limb if the detention is unlawful.
- Act early if you were pressed. Section 19 gives the option to the party whose consent was caused by coercion; take advice promptly about exercising it.
- Keep evidence. Messages, call logs and witnesses help show what was said before signing.
- Check the underlying law. Limb 1 depends on what the Penal Code forbids, which this article does not list.
