Optional Registration under Section 18 of the Registration Act, 1908: Which Documents May Be Registered, the Eleven Month Lease, the Advantages of Voluntary Registration, and What It Does Not Change

Section 18 is the mirror of Section 17. It lists the documents that a party may register if he chooses: instruments dealing with immovable property below one hundred rupees, short leases, instruments relating to movable property, wills, and, as a residual clause, all other documents not required by Section 17 to be registered. Nothing turns on a failure to register them, because Section 49 has no application to a document that the law never required to be registered. What voluntary registration buys is evidence, preservation and priority, and it is worth knowing exactly how much of each.

The clauses of Section 18, the advantages of registering anyway, and the limits

1. The Section

Section 18, Registration Act, 1908, in substance

Any of the following documents may be registered under this Act:

(a) instruments, other than instruments of gift and wills, which purport or operate to create, declare, assign, limit or extinguish, whether in present or in future, any right, title or interest, whether vested or contingent, of a value less than one hundred rupees, to or in immovable property;

(b) instruments acknowledging the receipt or payment of any consideration on account of the creation, declaration, assignment, limitation or extinction of any such right, title or interest;

(c) leases of immovable property for any term not exceeding one year, and leases exempted under section 17;

(cc) instruments transferring or assigning any decree or order of a Court or any award where the right, title or interest is of a value less than one hundred rupees;

(d) instruments, other than wills, which purport or operate to create, declare, assign, limit or extinguish any right, title or interest to or in movable property;

(e) wills; and (f) all other documents not required by section 17 to be registered.

2. The Practical Categories

Instruments below one hundred rupees, which in modern conditions are rare, though the clause still governs small interests.
Short leases. A lease for a term not exceeding one year, which does not reserve a yearly rent, falls outside Section 17(1)(d) and is optional here.
Movable property. Instruments dealing with movables never fall within Section 17, since that section is confined to immovable property. A hypothecation of machinery, an assignment of goodwill or a transfer of shares may be registered voluntarily, though other statutes may impose their own requirements.
Wills, dealt with in a separate note.
Agreements to sell, powers of attorney, receipts not within Section 17(1)(c), family arrangements recorded after the event, and memoranda: all fall within the residual clause (f), unless Section 17(1A) applies to the agreement.

3. The Eleven Month Lease

📖 Anthony v. K. C. Ittoop & Sons, (2000) 6 SCC 394

Facts: A person was inducted into possession of a building under a lease deed ostensibly for five years, which was compulsorily registrable but had not been registered. He paid monthly rent. When eviction was sought, it was argued that the deed was void and that he was therefore not a tenant at all.

Held: The Supreme Court held that the unregistered instrument could not create a lease for the term it stated, because of the combined effect of Sections 17 and 49 of this Act and Section 107 of the Transfer of Property Act. But the court is not thereby disabled from deciding whether a lease arose otherwise than through the deed. On delivery of possession and payment of monthly rent, the presumption that a lease not exceeding one year stood created by the conduct of the parties was unrebutted.

Ratio: An unregistered lease deed cannot create the term it recites, but the conduct of the parties may create a lease not exceeding one year, which needs no registration.

This is why so many leases in India are written for eleven months. A term not exceeding one year, without a reservation of yearly rent, is optional under Section 18(c), so the parties avoid registration and its stamp consequences. Where a longer lease is left unregistered, the result is not that the occupant is a trespasser: on the authorities, including Burmah Shell Oil Distributing Co. v. Khaja Midhat Noor, AIR 1988 SC 1470 and Park Street Properties (P) Ltd. v. Dipak Kumar Singh, (2016) 9 SCC 268, the tenancy is generally treated as one from month to month under Section 106 of the Transfer of Property Act.

4. The Advantages of Voluntary Registration

A permanent record. The document is copied into the appropriate book, and a certified copy is available under Section 57 if the original is lost.
Priority under Section 50. A registered document of the kinds mentioned in clauses (a) to (d) of Section 17(1) and in clauses (a) and (b) of Section 18 takes effect, as regards the property comprised in it, against every unregistered document relating to the same property.
Notice. Section 3 of the Transfer of Property Act treats registration as notice of the contents to a person who afterwards deals with the property.
Evidentiary value. The endorsements and the certificate under Section 60 record the date, the parties' appearance and the admission of execution, which makes later denial difficult.
Proof of execution. Section 60(2) makes the certificate admissible for proving that the document was duly registered and that the facts mentioned in the endorsements occurred as stated.

5. What It Does Not Change

It does not alter the nature of the instrument. An agreement to sell remains an agreement to sell; registering it does not turn it into a conveyance.
It does not improve the title. Registration proves nothing about the executant's ownership or authority.
It does not make Section 49 relevant. That section applies only to documents required to be registered. An optional document left unregistered is fully valid and admissible.
It does not extend the time for anything. Sections 23 to 26 still govern presentation, and a will remains outside them under Section 27.
It does not cure a stamp deficiency. The Stamp Act operates independently, and an insufficiently stamped instrument is inadmissible until duty and penalty are paid.

6. The Position Stated Shortly

Section 18 lists the documents that may be registered at the party's choice.
They include instruments below Rs. 100, acknowledgments, short leases, transfers of small decrees, movable property instruments, wills, and all documents not within Section 17.
A lease for a term not exceeding one year, without a yearly rent, is optional under Section 18(c), which explains the eleven month lease.
Anthony v. K. C. Ittoop: an unregistered long lease creates no term, but conduct may create a lease not exceeding one year.
Voluntary registration gives a permanent record, priority under Section 50, notice, and evidentiary value under Section 60.
It does not change the nature of the instrument, improve the title, or bring Section 49 into play.
