Cases checked to exist. Read the judgment before quoting a holding.

Every case cited here has been checked to exist — the citation resolves and names the right parties. The propositions attributed to each case have not been verified line by line against the judgment. Case names link through to the full judgment: read it before quoting a holding in an examination answer, and never carry a proposition from notes into court on trust.

Two questions carry this unit. “Define mortgage and explain its kinds” and “Once a mortgage, always a mortgage. Explain.” Both were set as 10-mark questions in January 2026. Learn section 58 clause by clause, with the remedy that goes with each kind, and learn section 60 with the clog cases.

1. Definition: section 58(a)

A mortgage is the transfer of an interest in specific immovable property for the purpose of securing the payment of money advanced or to be advanced by way of loan, an existing or future debt, or the performance of an engagement which may give rise to a pecuniary liability. The transferor is the mortgagor, the transferee the mortgagee; the principal money and interest secured are the mortgage-money, and the instrument is the mortgage-deed.

Formalities (section 59). Where the principal money secured is one hundred rupees or more, a mortgage (other than a mortgage by deposit of title deeds) can be made only by a registered instrument signed by the mortgagor and attested by at least two witnesses. Below one hundred rupees, it may be made by such an instrument or, except for a simple mortgage, by delivery of the property.

2. The six kinds

3. Mortgage by conditional sale or sale with a right of repurchase?

The proviso to s.58(c) says that no transaction shall be deemed a mortgage by conditional sale unless the condition is embodied in the document which effects or purports to effect the sale. A reconveyance clause in a separate deed therefore cannot convert a sale into a mortgage, though it may give a contractual right of repurchase.

Even where the condition is in the same deed, the question remains whether the parties meant a loan secured on land or a real sale with an option to buy back. In Umabai v. Nilkanth Dhondiba Chavan, 2005 INSC 203, (2005) 6 SCC 243, the Supreme Court treated it as a question of the intention of the parties gathered from the document read as a whole, with surrounding circumstances admissible. Pointers the courts use:

The difference matters. A mortgagor has a right to redeem that lasts until it is extinguished by act of the parties or decree, and limitation runs for thirty years. A seller with a right of repurchase has only a personal contractual right, which must be exercised strictly within the time fixed, failing which it is lost.

4. “Once a mortgage, always a mortgage” and clogs on redemption

Section 60 gives the mortgagor, at any time after the principal money has become due, the right on payment or tender of the mortgage-money to have the deed and documents returned, possession restored, and the property retransferred. The proviso is short: the right is lost only by act of the parties or decree of a court. From this flows the equitable maxim traced to the Court of Chancery (Lord Eldon in Seton v. Slade, 1802): a mortgage cannot be turned into something else by a stipulation in it. A term that prevents or unduly fetters redemption is a clog on the equity of redemption and is void.

English examples: Noakes & Co. v. Rice (1902), where a tie obliging a publican to buy the mortgagee's beer even after redemption was struck down; contrast Kreglinger v. New Patagonia Meat and Cold Storage Co. (1914), where a collateral advantage that did not fetter redemption itself was upheld.

Two related rules: the mortgagee cannot buy the equity of redemption in the mortgage deed itself, but a later, independent agreement by which the mortgagor sells his equity to the mortgagee is valid; and the right to redeem is barred by limitation thirty years after it accrues (Article 61, Limitation Act, 1963).

Trap. Do not say every long-term mortgage is a clog. Ganga Dhar itself rejected that. The test is whether the term defeats or penalises redemption, judged on the facts at the date of the mortgage.

5. Problem

A borrows Rs 5 lakh from B and executes a registered deed “selling” his house to B for Rs 5 lakh (market value Rs 25 lakh), with a clause that if A repays Rs 5 lakh with interest within three years B will reconvey, otherwise the sale becomes absolute. A stays in the house and pays B interest. In year four A tenders the money. B says the sale is absolute.

Issue. Whether the deed is a sale with a right of repurchase or a mortgage by conditional sale.

Law. Section 58(c) and its proviso; intention gathered from the deed and circumstances (Umabai); section 60 and the clog doctrine.

Application. The condition is in the same deed, so the proviso is satisfied. The money was a loan, interest is being paid, the price is one-fifth of value, and A kept possession. All point to security, not sale.

Conclusion. It is a mortgage by conditional sale. The clause making the sale absolute on default does not end A's right; that right ends only by act of the parties or decree, so B must sue for foreclosure. Until a decree, A may redeem on paying the mortgage-money.

How this is examined

The 10-mark essay is “Define mortgage. Explain the different kinds of mortgages under the Transfer of Property Act”: definition, the three elements, s.59 formalities, then each kind with its remedy. The second essay is “Once a mortgage always a mortgage”: s.60, the proviso, the clog doctrine, Ganga Dhar and Pomal Kanji, and a line on conditional sale versus repurchase. Short notes: usufructuary mortgage; mortgage by deposit of title deeds; anomalous mortgage.
