”Mortgage inter alia means transfer of interest in the specific immovable prop erty for the purpose of securing the money advanced by way of loan. Section 17(1)(c) of the Registration Act provides that a non-testamentary instrument which acknowledges the receipt or payment of any consideration on account of the creation, declaration, assignment, limitation or extension of any such right, ti tle or interest, requires compulsory registration. Mortgage by deposit of title-deeds in terms of Section 58(f) of the Transfer of Property Act surely acknowledges the receipt and transfer of interest and, therefore, one may contend that its registration is compulsory.
However, Section 59 of the Transfer of Property Act mandates that every mortgage other than a mortgage by deposit of title-deeds can be effected only by a registered instrument. In the face of it, in our opinion, when the debtor deposits with the creditor title-deeds of the property for the purpose of security, it becomes mort gage in terms of Section 58(f) of the Transfer of Property Act and no registered instrument is required under Section 59 thereof as in other classes of mortgage. The essence of mortgage by deposit of title-deeds is handing over by a borrower to the creditor title-deeds of immovable property with the intention that those doc uments shall constitute security, enabling the creditor to recover the money lent. After the deposit of the title-deeds the creditor and borrower may record the trans action in a memorandum but such a memorandum would not be an instrument of mortgage. A memorandum reducing other terms and conditions with regard to the deposit in the form of a document, however, shall require registration under Section 17(1)(c) of the Registration Act, but in a case in which such a document does not incorporate any term and condition, it is merely evidential and does not require registration.”
