Definition
A free and voluntary agreement to an act — in criminal law, a defence that the victim's genuine consent negates the offence in certain categories of cases; in contract law, a prerequisite for a valid contract.
Consent plays dual roles in Indian law: (a) In criminal law (Section 21 BNS, formerly Section 87 IPC): consent of the victim may negate certain offences. A person has the right to consent to acts that may harm only themselves — though consent is not a defence to acts causing death or grievous hurt unless consent is given for genuine medical purposes. Consent cannot be given by intoxicated persons, insane persons, or children under 12 (consent of a child below 12 is ineffective — Section 21 BNS Proviso). (b) In contract law (Section 13-14 ICA): consent of both parties is essential for a valid contract — consent obtained by coercion, undue influence, fraud, misrepresentation, or mistake is not 'free consent' and makes the contract voidable.
Statutory Definition
Section 21, Bharatiya Nyaya Sanhita (BNS), 2023 (formerly Section 87 IPC): 'Nothing which is not intended to cause death, or grievous hurt, and nothing which is not known by the doer to be likely to cause death or grievous hurt, is an offence by reason of any harm which it may cause, or be intended by the doer to cause, to any person for whose benefit it is done in good faith, and who has given a consent, whether express or implied, to suffer that harm, or to take the risk of that harm.' Proviso: 'Provided that the person giving the consent was not under twelve years of age, was not of unsound mind, and consent was not given under intoxication or deception.'
Etymology & Origin
From Latin 'consensus' (agreement, accord) from 'consentire' (to agree, to consent) from 'con' (together) + 'sentire' (to feel, to think). Consent is a 'feeling together' — a meeting of minds in agreement.
Full Legal Analysis
Consent: The Cornerstone of Autonomy
Consent is the law’s recognition of individual autonomy — the principle that every person is the master of what happens to their own body and property. Where a person freely and knowingly agrees to something, their agreement transforms what would otherwise be an interference into a permissible act. Medical surgery, boxing matches, consensual sexual activity — all involve acts that would otherwise be criminal but are rendered lawful by genuine consent.
Limits on Consent as a Defence
(a) Death or grievous hurt: Consent is not a defence where death or grievous hurt is caused — even if the victim 'consented' to be killed or severely harmed. Exception: genuine surgical consent for life-saving operations (where death is an unintended risk). (b) Age: A child under 12 cannot give effective consent — their apparent agreement is not legally valid. (c) Unsound mind: A person of unsound mind cannot give effective consent. (d) Intoxication or deception: Consent obtained through intoxication or fraud/deception is ineffective. (e) Sexual offences: In rape cases, consent is vitiated by fear of injury, threat, fraud, position of authority, intoxication, or if the woman is under 18 (POCSO Act).
Free Consent in Contract Law: ICA Sections 13-14
In contract law, 'free consent' requires the absence of five vitiating factors (Section 14 ICA): (a) coercion (Section 15 ICA — committing an act forbidden by the BNS or threatening to do so); (b) undue influence (Section 16 — domination of will by a person in a position of authority/trust); (c) fraud (Section 17 — deliberate misrepresentation to deceive); (d) misrepresentation (Section 18 — innocent but incorrect representation); and (e) mistake (Section 20-22 — operative mistake about essential facts). Absence of free consent makes the contract voidable at the option of the aggrieved party.
“Consent is the difference between medicine and assault, between love and rape, between a contract and coercion. The law protects consent as the foundation of human agency — and equally protects the most vulnerable by ensuring that apparent consent is genuine, informed, and free.”

Bharatiya Nyaya Sanhita, 2023, 2023
"Nothing which is not intended to cause death, or grievous hurt, is an offence by reason of any harm which it may cause to any person for whose benefit it is done in good faith, and who has given a consent, whether express or implied, to suffer that harm, or to take the risk of that harm."
Consent as criminal defence: victim's consent negates offence for non-death/grievous-hurt cases — child under 12 cannot consent
