15 The respondent contends that there is no serious question to be tried because the consideration for the unregistered mortgage was past, save for the amount of $25,000.00 advanced by the plaintiff after the date of execution of that mortgage. The unregistered mortgage was executed on 5 April 2001 and amended by increasing the amount thereof from $90,000.00 to $115,000.00 on 14 May 2001. It was common ground that the plaintiff had advanced a total of $90,000.00 to the respondent by 16 March 2001 and advanced a further $5,000.00 to him on 8 May 2001, $10,000.00 on 15 May 2001 and $10,000.00 on 8 June 2001. Accordingly, by the date of the execution for the first time of the mortgage, $90,000.00 had been advanced and thereafter the further sum of $25,000.00 had brought the total amount of those loans to the figure of $115,000.00 being the amount of the mortgage as amended.
