Introduction

A signed contract is often assumed to be conclusive proof of an agreement, yet legal reality is far more nuanced. Modern electronic communications and e-signatures have made contract execution faster, but courts frequently encounter signed agreements that are unenforceable. A signature indicates intention, not legality; an agreement becomes binding only when it satisfies all essential elements of a valid contract, including free consent, competent parties, lawful consideration, and consensus ad idem. Without these, even a formally executed contract may fail in law.

Legal Context

Under Indian law, a contract is not enforceable just because it has been signed. Section 10 of the Indian Contract Act, 1872 says that an agreement becomes a contract only if it is made by the free consent of parties who are competent to contract, for a lawful consideration, with a lawful object, and is not expressly declared void. Section 7 adds that acceptance must be absolute and unqualified, leaving no room for doubt.

A valid contract depends on three key things: certainty, commitment, and communication. If any of these is missing in the offer or acceptance, there is no valid contract. Section 11 says a person is competent if they are of majority age, of sound mind, and not disqualified by law.

Consent, defined in Sections 13 and 14, happens when both parties agree on the same thing in the same sense. Consent is free only if it is not obtained through coercion (Section 15), undue influence (Section 16), fraud (Section 17), misrepresentation (Section 18), or mistake (Sections 20–22). Section 19 says that if consent is affected by coercion, undue influence, fraud, or misrepresentation, the contract is voidable at the choice of the affected party. Section 20 says that if both parties are mistaken about an essential fact, the contract is void, though a mistake about the value of the thing does not make it void.

In short, for a contract to be enforceable, parties must be competent, consent freely, and all essential terms must be lawful and certain—not just signed.

Practical illustration;

In Rickmers Verwaltung GMBH v. Indian Oil Corporation Ltd., the Supreme Court held that despite extensive email and fax exchanges, no binding contract arose because the parties never reached final agreement on essential terms such as the letter of credit and performance guarantee. The correspondence reflected ongoing negotiations rather than a concluded contract

Similarly, a contract may fail due to mutual mistake. In cases involving sale of land where both parties were mistaken regarding the area or price—facts essential to the agreement—the contract has been held void ab initio. Consequently, ancillary clauses such as forfeiture provisions also become unenforceable, even when invoked as a defence in suits for specific performance.

Contracts may also fail where they are unlawful. Even if a statute does not expressly prohibit an act but imposes a penalty for performing it, any agreement to carry out such an act is void, as the law does not penalise conduct it considers lawful.

Further, agreements opposed to public policy are void under Section 23. A classic example is auction collusion, where bidders form a ring to suppress prices, thereby defrauding third parties such as debtors, the government, or the public. Such agreements undermine fairness and transparency and are therefore unenforceable, regardless of whether they are formally executed.

Together, these examples show that contracts can fail  even if signed by the parties.

Risks and Common Mistakes

Many contracts fail because parties overlook fundamental legal requirements or commit avoidable errors. One of the most significant risks is lack of clarity. Where the terms of an agreement are uncertain, ambiguous, or incomplete, the contract may become unenforceable, even if it has been duly signed. In such cases, ambiguity can render the agreement void or voidable at the instance of the affected party.

Another common mistake is the failure to ensure free and informed consent. Contracts entered into under coercion, undue influence, fraud, or misrepresentation are voidable at the option of the aggrieved party. Similarly, where both parties act under a mutual mistake relating to essential facts, the agreement is void from its inception.

A further risk arises when the contract is illegal or opposed to public policy. Even where an act is not expressly prohibited by statute but attracts a statutory penalty, any agreement to perform such an act is void. Agreements that defraud third parties or undermine public interest—such as collusive bidding in auctions—are unlawful and unenforceable.

Finally, parties often assume that a signature alone guarantees enforceability. In reality, a valid contract requires competent parties, free consent, lawful consideration, a lawful object, and certainty of terms. Ignoring these essential elements frequently results in contracts failing in law, leading to financial loss and avoidable litigation.

Solution :

In suits for specific performance, courts insist upon absolute certainty of terms and clear consensus ad idem. The burden lies on the claimant to establish that the agreement was complete, final, and binding in all material respects. Even where both parties have signed the document, courts will refuse enforcement if the terms are vague or the surrounding correspondence indicates that negotiations were ongoing.

It is well settled that, while interpreting contractual documents including insurance contracts, courts must give effect to the words chosen by the parties. Courts cannot rewrite agreements or supply missing terms on grounds of fairness or equity. Judicial determination must rest strictly on what the parties have expressly agreed.

This explains why contracts fail despite execution. Where essential terms are left open or subject to future negotiation, courts have no option but to hold that no binding contract exists. The most effective solution lies at the drafting stage: ensuring clarity of material terms, clearly defining “subject to” conditions, and maintaining consistency in correspondence to reflect a concluded agreement rather than ongoing negotiations.

Conclusion :

The enforceability of a contract ultimately depends on substance rather than form. Courts will not uphold agreements that are vague, incomplete, unlawful, or entered into under compromised consent, regardless of whether they are signed. Precision, clarity, and compliance with legal requirements at the drafting stage are essential to avoid disputes. Ensuring that all material terms are definite and that negotiations are conclusively reflected in the contract is the most effective safeguard against failure. Signatures alone cannot substitute for these fundamental principles
