A contingent interest is one that depends on a future event that may or may not happen. Section 21 of the Transfer of Property Act, 1882 says when an interest is contingent, when it turns into a vested interest, and one exception for gifts that depend on reaching an age. This article reads it as per the text of the Act consulted.
Where an interest is created to take effect only on the happening of a specified uncertain event, or if a specified uncertain event shall not happen, the person acquires a contingent interest. It becomes vested on the happening of the event in the first case, and when the happening of the event becomes impossible in the second. Exception: if a person becomes entitled to an interest on attaining a particular age and the transferor also gives him the income absolutely before that age, or directs the income (or as much as is necessary) to be applied for his benefit, the interest is not contingent.
What makes an interest contingent
Section 21 starts: "Where, on a transfer of property, an interest therein is created in favour of a person to take effect only on the happening of a specified uncertain event, or if a specified uncertain event shall not happen, such person thereby acquires a contingent interest in the property."
Two features matter.
- The event is specified. The document names it.
- The event is uncertain. It may or may not happen. Compare section 19, where an interest that takes effect on an event "which must happen" (such as a death) is vested. Our article on sections 19 and 20, vested interest sets out that side.
There are two forms:
| Form | Example wording |
|---|---|
| Takes effect only if an uncertain event happens | "To Neha if she qualifies as a chartered accountant" |
| Takes effect if an uncertain event does not happen | "To Neha if she does not leave India before 2040" |
The person acquires a contingent interest in either case. It is a real interest, but it is not yet a fixed one. A contingent holder needs to watch the event, because his interest may never become vested.
Practical point. A buyer or lender looking at a property should ask whether any interest in it is contingent. A seller who holds only a contingent interest may not have a vested right to give. If you are reading successive gifts in a family deed, a legal consultation can help separate the vested interests from the contingent ones.
When a contingent interest becomes vested
The second paragraph of section 21 says: "Such interest becomes a vested interest, in the former case, on the happening of the event, in the latter, when the happening of the event becomes impossible."
| Form | Becomes vested when |
|---|---|
| Takes effect on an event happening (former case) | The event happens |
| Takes effect if an event does not happen (latter case) | It becomes impossible for the event to happen |
Example (former case). Rohit Saxena transfers a house to Divya "if she passes the CA final examination". Divya has a contingent interest. When she passes, the event has happened and the interest becomes vested.
Example (latter case). Rohit's transfer reads "to Divya if she does not marry before the age of 25". Divya's interest is contingent until the happening of the event becomes impossible. Once she turns 25 unmarried, the event (marriage before 25) can no longer happen, and her interest becomes vested.
The Exception: an age condition with income
The Exception deals with a common family arrangement: a gift that takes effect when a person reaches a particular age. Reaching an age is not, by itself, described in the first paragraph; the Exception says what happens when the transferor deals with income in a particular way.
Where, under a transfer, a person becomes entitled to an interest upon attaining a particular age, and the transferor also:
- gives him absolutely the income to arise from the interest before he reaches that age; or
- directs the income, or so much of it as may be necessary, to be applied for his benefit,
the interest "is not contingent".
Example. Kavita Rao transfers a plot to her nephew Arjun, who is 12, "to be his when he is 25". She also directs that the rent from the plot be used for Arjun's school fees and upkeep until then. Because the transferor directs the income to be applied for his benefit before the age, the Exception says Arjun's interest is not contingent. Compare a transfer where Kavita says nothing about the income: the Exception would not apply on its terms and the document would have to be read under the other sections.
The Exception turns on the transferor's treatment of income. It does not apply to other kinds of contingency, such as qualifying in an examination.
Vested versus contingent: side by side
| Point | Vested interest | Contingent interest |
|---|---|---|
| Event | None, or an event that must happen, or forthwith | A specified uncertain event |
| Holder's position | Already holds it, may wait to enjoy | May never get it |
| Becomes vested | Already vested | On the event, or when the event becomes impossible |
| Section | 19 and 20 | 21 |
Other sections build on this. Sections 22 to 24 deal with transfers to members of a class who attain a particular age, transfers contingent on an uncertain event with no time stated, and transfers to survivors; see our article on sections 22 to 24. Sections 25 and 26 deal with conditions that must be fulfilled; see our article on sections 25 and 26, conditional transfer and condition precedent.
Drafting points
- Name the event clearly. A vague event makes it hard to say when the interest vests.
- Decide whether you want the interest to be held now (vested) or only on the event (contingent), and use words that show it.
- If you want an age gift to be vested, consider dealing with income as the Exception describes.
- Keep the record of when the event happened, for instance a certificate, because the date of vesting can matter later.
- Do not assume an age condition always makes an interest contingent; read the Exception.

The difference between vested and contingent can decide who may sell, mortgage or claim a property. We can review your deed or family arrangement through a legal consultation.
Key takeaways
- A contingent interest arises where an interest takes effect only on a specified uncertain event, or if such an event does not happen.
- It becomes vested on the happening of the event (first case) or when the event becomes impossible (second case).
- The Exception removes the contingent label where a person becomes entitled on attaining a particular age and the income before that age is given to him absolutely or applied for his benefit.
- A vested interest is held now; a contingent interest may never take effect.
- Name the event clearly in any deed.
- Later amendments and State changes should be checked.
