The correct answer is (a). Section 58(f) of the Transfer of Property Act defines anomalous mortgage.
A mortgage is a security interest in real property that is used to secure a debt. The mortgagee (lender) holds the title to the property until the debt is repaid, at which point the mortgage is discharged.
An anomalous mortgage is a mortgage that is not created in accordance with the requirements of the Transfer of Property Act. For example, an anomalous mortgage may be created without a written agreement, or it may be created for an indefinite period of time.
Section 58(f) of the Transfer of Property Act states that “a mortgage created without a written agreement, or for an indefinite period of time, is void.” This means that an anomalous mortgage is not a valid security interest, and the mortgagee does not have a right to the property.
The other options are incorrect because they do not define anomalous mortgage. Section 58(d) defines a mortgage by demise, Section 58(g) defines a mortgage by sub-demise, and Section 58(1) defines a mortgage by conditional sale.
