"19 All three parties, that is the plaintiff, defendant and Mr Oteri, knew that the defendant held a first mortgage G545917 over the Alness Street property, that it secured the repayment of $491,000, that Mr Oteri had purchased the Duncraig Road property and that the first defendant was to advance a further $40,000 to assist Mr Oteri pay the deposit on the Duncraig Road property. All three parties knew that Mr Pourzand had a second mortgage G647605 registered over the Alness Street property. All parties knew that Mr Oteri intended to sell, and did sell, the Alness Street property; they knew that as a result, when the Alness Street property was sold, both the defendant's first mortgage and the plaintiff's second mortgage were to be discharged, that a new first mortgage was to be taken by the defendant over the Duncraig Road property and that Mr Pourzand was to take a new second mortgage over the Duncraig Road property. All parties knew that as a condition of the $40,000 advance, the defendant required Mr Pourzand execute a deed of priority. All parties knew that the loan of $491,000 was to be 'swapped', meaning that Mr Oteri would remain indebted for that amount as well as the extra $40,000 after the settlement regarding the Duncraig Road property. The deed of priority, when prepared, referred to the rule in Hopkinson v Rolt so all three parties can be taken to understand, in general terms at least, the effect of the rule.
20 The rule in Hopkinson v Rolt has the effect that a first mortgagee whose mortgage is taken to cover what is then due and also future advances, cannot rely on the first mortgage to recover the future advances in priority over a second mortgagee if the first mortgagee had notice of the second mortgagee before it made the new advances. Neither of the parties to the litigation deny that the rule in Hopkinson v Rolt applies to mortgages under the Transfer of Land Act. As to which, see Matzner v Clyde Securities Ltd [1975] 2 NSWLR 293 and Mercantile Credits Ltd v Australian & New Zealand Banking Group (1988) 46 SASR 407. All parties knew that the defendant knew about Mr Pourzand's mortgage, and that this meant that the defendant could not advance further moneys and treat the first mortgage as security for that further advance, unless Mr Pourzand agreed that the defendant had priority for such an advance. If Mr Pourzand did not agree and moneys were advanced by the defendant, then although the first mortgage was a first mortgage, and although it was an 'all money' security, the defendant would rank in priority after Mr Pourzand, and the additional moneys advanced would only be recoverable under the first mortgage after Mr Pourzand had been paid out the money due under his mortgage.
21 The parties therefore all understood that the deed of priority was to order the affairs of the first and second mortgagees, so that the defendant ranked first for payment of a sum not exceeding $531,000, which was the original debt plus the additional $40,000.
22 All the parties knew, or reasonable parties in their position would have known, that the mortgages over the Duncraig Road property, upon registration, were given a number by the Land Titles Office which would be different from the number on the mortgages over the Alness Street property.
23 I find that Mr Pourzand did not know that the defendant had agreed with Mr Oteri to advance a further $136,500 after settlement on the Duncraig Road property."
