Sufficiency of Consideration

Meaning of Sufficiency of Consideration

Sufficiency of consideration refers to whether the consideration has some legal value recognized by law and is sufficient to support the promise.

In Indian contract law, consideration does not have to be equal to the value of the promise. However, it must be real, lawful and legally recognizable.

For example, A agrees to sell his watch to B for ₹1,000. Even if the watch is worth ₹5,000, the ₹1,000 may still be legally sufficient consideration because it has monetary value and was voluntarily agreed upon.

Thus:

Sufficiency of consideration means legal sufficiency, not economic equality.

Statutory Basis

The concept of sufficiency arises primarily from Section 2(d) of the Indian Contract Act, 1872, which defines consideration as an act, abstinence or promise done or given at the desire of the promisor.

The Act does not expressly use the phrase “sufficient consideration” as a separate statutory requirement.

Instead, consideration must satisfy the legal requirements of Section 2(d), including that it must be something legally recognizable.

At the same time, Explanation 2 to Section 25 makes it clear that consideration need not be adequate.

Therefore, Indian contract law distinguishes between:

• Sufficiency — whether there is legally recognizable consideration.
• Adequacy — whether the consideration is proportionate to the value of the promise.

What Makes Consideration Sufficient?

1. It must have legal value

Consideration must involve something that the law recognizes as having value.

For example:

A promises to pay B ₹10,000 if B provides a legal service.

B’s service has legal value and can constitute consideration.

2. It must be real

Consideration cannot be imaginary, illusory or meaningless.

For example:

A promises to pay B ₹10,000 if B performs an impossible act.

The purported consideration is not legally meaningful.

3. It must be lawful

Under Section 23, consideration must not be unlawful.

For example:

A promises to pay B ₹1 lakh for carrying out an illegal act.

The consideration is unlawful and cannot support an enforceable contract.

4. It must be given at the desire of the promisor

The consideration must satisfy the requirement of Section 2(d).

An act performed independently and without the promisor’s desire does not automatically become consideration merely because it benefits the promisor.

This principle was emphasized in Durga Prasad v. Baldeo (1880).

5. It must not be merely moral consideration

A moral obligation by itself does not generally constitute contractual consideration.

For example:

A promises to pay B ₹10,000 simply because B is his friend.

Friendship alone is not consideration.

However, specific statutory exceptions may make certain promises enforceable even without ordinary consideration.

Sufficiency Does Not Mean Adequacy

This is the most important distinction.

Adequacy

Adequacy asks:

Is the consideration economically proportionate to the promise?

Sufficiency

Sufficiency asks:

Does the consideration have legally recognizable value?

For example:

A sells a car worth ₹10 lakh to B for ₹3 lakh.

The ₹3 lakh consideration may be:

• Inadequate economically, because it is much lower than the value of the car;
• but sufficient legally, because it has monetary and legal value.

Therefore:

Adequate consideration is not necessary, but legally sufficient consideration is necessary.

Examples

Example 1: Money

A sells a laptop to B for ₹30,000.

The payment of ₹30,000 is legally sufficient consideration.

Example 2: Service

A promises to pay B ₹20,000 in return for B’s professional services.

The service can constitute sufficient consideration.

Example 3: Abstinence

A owes B ₹1 lakh. B agrees, at A’s request, to refrain from enforcing the debt for a specified period in return for A’s promise.

The agreed abstinence can constitute consideration.

Example 4: Inadequate but Sufficient

A sells property worth ₹20 lakh to B for ₹8 lakh.

The ₹8 lakh may be inadequate compared with the property’s value, but it is still legally recognizable consideration.

The transaction does not become void merely because the consideration is inadequate.

Insufficient Consideration vs Inadequate Consideration

These terms should not be confused.

Inadequate Consideration

Consideration exists and has legal value, but it is less than the economic value of the promise.

Example:

A ₹10 lakh car is sold for ₹4 lakh.

The ₹4 lakh is inadequate but may be legally sufficient.

Insufficient Consideration

The purported consideration lacks the necessary legal value or fails to satisfy the requirements of consideration.

Example:

A promises to pay B ₹10,000 merely because B is his friend, without any act, abstinence or promise forming consideration.

There may be no legally sufficient consideration.

Sufficiency and Adequacy: Key Difference

Basis	Sufficiency	Adequacy
Meaning	Whether consideration has legal value	Whether consideration is proportionate in economic value
Legal requirement	Consideration must have legal value	Not required
Example	₹5,000 paid for a service	₹5,000 paid for something worth ₹20,000
Effect	Lack of legally valid consideration may affect enforceability	Inadequacy alone does not make agreement void
Main principle	Legal sufficiency	Economic fairness

Sufficiency of Consideration and Section 25

Section 25 contains the general rule:

An agreement made without consideration is void, subject to specified exceptions.

This makes the existence of legally valid consideration important.

However, the consideration does not have to be economically adequate.

Explanation 2 to Section 25 provides that an agreement is not void merely because the consideration is inadequate, although inadequacy may be considered by the court in determining whether consent was freely given.

Thus:

No consideration → Generally void

Inadequate consideration → May still be valid

Sufficiency and Free Consent

Inadequacy may become important where the circumstances suggest that consent was not free.

For example:

A owns property worth ₹50 lakh but agrees to sell it for ₹5 lakh to a person who is in a position to dominate A’s will.

The ₹5 lakh may be legally sufficient consideration. However, the extreme inadequacy may be relevant evidence when examining whether undue influence was exercised.

Therefore, the law does not automatically invalidate the contract because the price is low.

Important Case: Durga Prasad v. Baldeo

Durga Prasad v. Baldeo (1880)

The case established that consideration must move at the desire of the promisor.

The plaintiff had constructed a market at the request of the Collector, but the shopkeepers later promised to pay him commission. Since the construction was not done at the shopkeepers’ desire, it did not constitute consideration for their promise.

Principle: Consideration must satisfy the statutory requirement of being given or performed at the desire of the promisor.

Important Case: Chinnaya v. Ramaya

Chinnaya v. Ramaya (1882)

The case established that consideration may move from the promisee or any other person under Section 2(d).

It demonstrates that the legal sufficiency of consideration does not depend upon consideration necessarily coming directly from the promisee.

Important Case: Thomas v. Thomas

Thomas v. Thomas (1842)

This English case is commonly cited for the principle that consideration need not be economically adequate, provided it has legal value.

It is useful for understanding the distinction between legal sufficiency and economic adequacy.

Is Consideration Required to Be Equal?

No.

Indian contract law does not generally require the consideration to be equal to the value of the promise.

For example:

A provides a service worth ₹50,000 for ₹20,000.

The consideration may be economically inadequate, but that does not by itself invalidate the agreement.

The parties are generally free to determine the terms of their bargain.

Is Nominal Consideration Sufficient?

A very small amount can sometimes constitute legally sufficient consideration if it has genuine legal value and the other requirements are satisfied.

For example:

A transfers an item to B for ₹1 pursuant to a genuine contractual bargain.

The amount may be economically insignificant, but the existence of a legally recognizable bargain is what matters.

However, courts will examine the actual substance of the transaction where the consideration is merely illusory, sham or otherwise legally ineffective.

8. Section 25 generally makes agreements without consideration void, subject to exceptions.
9. Explanation 2 to Section 25 recognizes that inadequacy alone does not invalidate an agreement.
10. Durga Prasad v. Baldeo is important for the promisor’s desire.
11. Chinnaya v. Ramaya is important for consideration moving from any person.
12. Thomas v. Thomas is useful for explaining adequacy versus legal sufficiency.

Quick Revision

Sufficiency: Whether consideration has legally recognizable value.

Adequacy: Whether consideration is economically proportionate.

Must consideration be adequate? No.

Must consideration have legal value? Yes.

Main definition: Section 2(d)

Lawful consideration: Section 23

Agreement without consideration: Section 25, subject to exceptions

Important distinction:

Sufficient ≠ Adequate

A consideration may be legally sufficient but economically inadequate.

Conclusion

Sufficiency of consideration means that the consideration must possess legal value and satisfy the requirements of valid consideration. It does not mean that the consideration must be equal to or proportionate to the value of the promise. Under Indian contract law, adequacy is not required, but consideration must be real, lawful and legally recognizable. This distinction between legal sufficiency and economic adequacy is fundamental to understanding Section 2(d) and Section 25 of the Indian Contract Act, 1872.
