Mortgages 

A mortgage is security given over property for the performance of an obligation, almost always the repayment of a debt. It is easy to mistake a mortgage for a transfer of ownership to the lender, because that is close to how it worked historically — but that is precisely what the Torrens system changed.

A mortgage is security, not a transfer of ownership

At general law, a mortgage of land was structured as a conveyance of the mortgagor's estate to the mortgagee, defeasible (that is, liable to be undone) on repayment by the agreed date. Taken literally, this meant the lender became the legal owner and the borrower's right to get the land back was, strictly, contractual only. Equity intervened to protect borrowers by recognising an enduring right to redeem even after the contractual date for repayment had passed, called the equity of redemption, discussed further below.

Under the Torrens system, the position is restructured directly by statute: a registered mortgage does not transfer the mortgagor's estate to the mortgagee at all. The mortgagor remains the registered proprietor of the land. The mortgage instead takes effect as a registered charge or encumbrance over that title, giving the mortgagee defined statutory powers and priority, without ever vesting ownership in the mortgagee. This is a significant and deliberate departure from the general law position, and describing a Torrens mortgage as a transfer of ownership is a common student error worth avoiding explicitly.

The mortgagee's remedies on default

Once the mortgagor is in default (typically, failing to pay an instalment or breaching another term of the mortgage), the mortgagee's principal remedies are:

• Sue for the debt — an ordinary action for the money owed, available because the mortgage secures a personal obligation as well as creating an interest in the land.
• Take possession — a mortgagee generally has a right to take possession of the mortgaged property, historically exercisable even without default, though in practice constrained by the terms of the mortgage, by consumer protection legislation for residential lending, and by the mortgagee's practical preference to avoid the duties possession brings.
• Exercise the power of sale — the mortgagee's most commonly used remedy, allowing sale of the property and application of the proceeds first to the debt and costs, with any surplus returned to the mortgagor. The power must be exercised in good faith and with reasonable care as to price, per Forsyth v Blundell (1973) 129 CLR 477.¹ The power of sale is a creature of statute (or of the mortgage instrument read with statute) under each jurisdiction's Torrens legislation, and is conditional on preconditions such as a defined period of default and a valid notice to the mortgagor, the details of which differ between jurisdictions and must be strictly complied with before the power arises.
• Appoint a receiver, more commonly seen in mortgages over income-producing property or business assets, to collect income and manage the secured property pending sale.

Foreclosure — historically, an order vesting the mortgagor's estate absolutely in the mortgagee, extinguishing the equity of redemption — survives in modified and rarely used form under Torrens legislation in most jurisdictions, the power of sale having become the practical remedy of choice.

The equity of redemption

The equity of redemption is the mortgagor's right, recognised by equity, to redeem the mortgaged property by paying what is owed, even after the date fixed for repayment has passed, for as long as the mortgagee has not completed a valid sale or foreclosure. Equity treats this right as an incident of the security transaction that the parties cannot bargain away in substance: a term that purports to make the mortgagor's right to redeem illusory, or that confers a collateral advantage on the mortgagee extending beyond repayment of the debt and proper costs, risks being struck down as an unacceptable clog on the equity of redemption, even though sophisticated commercial mortgages are given considerable latitude in how they are structured.

Applying this in a problem question

1. Confirm the mortgage is over Torrens land and explain, if relevant, that the mortgagor remains registered proprietor — the mortgage is a charge, not a transfer.
2. Identify whether default has occurred and, if the mortgagee wishes to exercise the power of sale, whether the statutory preconditions (default period and notice) under the relevant jurisdiction's legislation have been satisfied.
3. Select the appropriate remedy or remedies for the mortgagee on the facts, and explain what each achieves and what it requires.
4. Ask whether any term of the mortgage improperly restricts or defeats the mortgagor's equity of redemption.
5. Trace where any sale proceeds go, remembering the mortgagee accounts to the mortgagor for any surplus after the debt and proper costs.
