Explainer · Property Law · Registration
Section 17 of the Registration Act, 1908 lists the documents that must be registered, such as gifts of immovable property, instruments that create or transfer a right in immovable property worth Rs 100 or more, and most leases for more than a year. Get this wrong and the document may not pass title or may be shut out as evidence. This explainer sets out what must be registered, what is optional, and the effect of not registering. Last verified October 2026.
- What it is: Section 17 of the Registration Act, 1908 lists documents that must be registered, mostly those affecting immovable property.
- Main categories: gifts of immovable property; instruments creating or transferring a right worth Rs 100 or more; and leases year to year, over one year, or reserving a yearly rent.
- Optional: Section 18 lists documents whose registration is optional, such as wills and short leases.
- If not registered: under Section 49, the document cannot affect the property or be used as evidence of that transaction, subject to a collateral-purpose saving.
01Why registration matters
Registration creates a permanent public record of a transaction in property. It tells the world who owns what, deters fraud and forgery, and lets a later buyer check the history of a title. Because of this, the law makes registration compulsory for the documents that most affect immovable property.
The stakes are high. If a document that was required to be registered is left unregistered, it can fail to transfer the right it was meant to transfer, and it can be shut out as evidence of that transaction. Many property disputes start with exactly this mistake.
02What Section 17 makes compulsory
Section 17(1) lists the documents whose registration is compulsory. The main categories are:
- Gifts of immovable property: an instrument of gift of immovable property must be registered, whatever its value.
- Instruments affecting immovable property worth Rs 100 or more: other non-testamentary instruments which create, declare, assign, limit or extinguish, whether now or in future, any right, title or interest in immovable property of the value of one hundred rupees and upwards.
- Instruments acknowledging receipt of consideration: non-testamentary instruments which acknowledge the receipt or payment of any consideration on account of the creation, declaration, assignment, limitation or extinction of any such right, title or interest.
- Leases: leases of immovable property from year to year, or for any term exceeding one year, or reserving a yearly rent.
- Decrees or awards affecting immovable property: non-testamentary instruments transferring or assigning a decree, order or award that creates a right in immovable property of the value of one hundred rupees and upwards.
A will is not compulsorily registrable; it is dealt with separately and its registration is optional.
03The Rs 100 threshold and leases
The Rs 100 value threshold is widely misunderstood. It applies to the category of non-testamentary instruments that create or transfer a right in immovable property. In practice almost all such instruments cross that very low figure, so the threshold rarely excludes anything today.
The threshold does not drive lease registration
Whether a lease must be registered depends on its term and rent, not on the Rs 100 figure. A lease year to year, for a term over one year, or reserving a yearly rent must be registered. Shorter leases outside these descriptions generally need not be, unless a State notification requires it.
Section 17(1A), added by the 2001 amendment, requires that a contract to transfer immovable property for the purposes of Section 53A of the Transfer of Property Act be registered. If it is not, it has no effect for that purpose. This connects directly to the doctrine of part performance under Section 53A.
04What is optional: Section 18
Section 18 lists documents whose registration is optional. These include instruments (other than gifts and those covered by Section 17) relating to immovable property of a value less than one hundred rupees, leases of immovable property not exceeding one year and not reserving a yearly rent, instruments acknowledging receipt of consideration covered by Section 18, wills, and certain other documents.
A party may register an optional document to give it the weight and public record that registration brings, but the law does not compel it. The dividing line between Section 17 and Section 18 is what decides whether a document is valid without registration.
05Effect of not registering
Section 49 of the Registration Act sets out the consequence. A document that is required to be registered but is not registered cannot affect any immovable property comprised in it, cannot confer any power to adopt, and cannot be received as evidence of any transaction affecting such property or conferring such power.
There is an important saving. The proviso to Section 49 allows such an unregistered document to be received as evidence of a contract in a suit for specific performance, or as evidence of any collateral transaction not required to be effected by a registered instrument. How far that saving goes is a question courts decide case by case, explained in whether an unregistered document is admissible in evidence.

08Frequently asked questions
Which documents must be compulsorily registered in India?
Under Section 17 of the Registration Act, 1908, the main ones are gifts of immovable property, non-testamentary instruments that create or transfer a right in immovable property worth Rs 100 or more, instruments acknowledging receipt of consideration for such rights, and leases from year to year, for a term over one year, or reserving a yearly rent.
Does a will have to be registered?
No. A will is not compulsorily registrable under Section 17. Its registration is optional. A person may register a will to give it a public record, but the law does not require it.
What is the Rs 100 threshold?
It applies to non-testamentary instruments that create, declare, assign, limit or extinguish a right in immovable property. Such an instrument must be registered where the value is one hundred rupees and upwards. The figure is very low, so almost all such instruments cross it. It does not decide whether a lease needs registration.
Which leases must be registered?
A lease of immovable property from year to year, for any term exceeding one year, or reserving a yearly rent must be registered under Section 17. Shorter leases that fall outside these descriptions generally need not be registered, unless a State notification requires it.
What happens if a compulsorily registrable document is not registered?
Under Section 49, it cannot affect the immovable property or be received as evidence of the transaction. It may still be used as evidence of a contract in a suit for specific performance, or of a collateral transaction that did not itself require registration.
