Section 16 of the Indian Contract Act, 1872: "Undue influence" defined

The provision

A contract is said to be induced by undue influence where the relations subsisting between the parties are such that one of the parties is in a position to dominate the will of the other and uses that position to obtain an unfair advantage over the other.

Indian Contract Act, 1872, Section 16. Official text.

What Undue Influence Means Under Indian Contract Law

Section 16 of the Indian Contract Act establishes that a contract becomes voidable if one party exploits a position of power or dominance over the other to gain an unfair advantage. The law recognises that certain relationships create inherent imbalances: one person may have psychological, emotional, financial, or social control over another. When that dominant party misuses that position to push the weaker party into a contract on unfavourable terms, the contract is tainted by undue influence.

Critically, undue influence does not require fraud, deception, or even dishonesty in the traditional sense. The focus is on abuse of a power imbalance, not on false statements or hidden facts. A person in a position of trust (doctor, solicitor, parent, employer, spiritual advisor) who extracts a contract from someone dependent on them may be found to have exerted undue influence, even if no overt pressure was applied.

Key Elements in Practice

Two conditions must exist: first, a relationship of dominance (actual or potential control over the other's will); and second, use of that position to secure an unfair advantage. Courts assess the nature of the relationship, the circumstances of contract formation, whether the weaker party had independent advice, and whether the terms are manifestly unreasonable.

The burden of proof is important: if the relationship is inherently fiduciary (trustee-beneficiary, parent-child, doctor-patient), the person in the dominant position must prove the contract was freely made. In other cases, the party alleging undue influence must establish it.

Contract Drafting and Negotiation Implications

For in-house teams, undue influence risk appears across multiple contract scenarios. In settlement agreements or releases involving parties of unequal bargaining power, document the presence of independent legal counsel for the weaker party. In contracts with employees, patients, beneficiaries, or other dependents, ensure written evidence of genuine consent: separate meetings, independent advice noted in writing, and clear explanations of rights.

When negotiating contracts where your organisation holds power (vendor relationships with sole-dependent suppliers, contracts with vulnerable populations, professional service agreements), be explicit: include clauses confirming each party had opportunity to seek independent legal advice, remove onerous or one-sided terms that might be challenged later, and avoid pressure tactics in formation. Courts scrutinise the fairness of terms themselves; heavily imbalanced provisions invite undue influence claims.

In high-stakes transactions (asset transfers, guarantees from family members, long-term service commitments), consider obtaining written confirmations from the less powerful party stating they understand their rights and have acted voluntarily. If challenged, a voidable contract requires rescission proceedings, but defending against undue influence claims is costly and risky. Prevention through procedural safeguards is far more efficient than litigation.

For contracts involving fiduciary relationships, the doctrine creates a presumption against you: you must affirmatively prove fairness and voluntary consent. This shifts the burden significantly, making procedural documentation essential.
