18 Finally, Mr and Mrs Siahos alleged that they were at a special disadvantage with respect to the plaintiff. Accordingly, at the time of their purported execution of the mortgage and at all other relevant times, the plaintiff took unconscientious advantage of them.
19 The plaintiff denied these allegations and asserted its right to rely upon its registered mortgage over the property. Alternatively, the plaintiff contended that the defendants were liable to repay all monies advanced to them on restitutionary principles.
Consideration
20 Mr and Mrs Siahos did not persist with the contention that they had not signed documents upon which the plaintiff relied that bore signatures purporting to be theirs. Instead they relied first upon the assertion that their signatures were procured by Peter's fraud and that the plaintiff should in the circumstances have known, or become aware, of that fact. Secondly, Mr and Mrs Siahos said that the plaintiff could not rely on any documents executed by Peter as their attorney to recover monies advanced by the plaintiff for Peter's benefit from them. Thirdly Mr and Mrs Siahos asserted that, either alone or in combination, these matters made it unconscionable for the plaintiff to rely upon its strict legal entitlement to possession of the property to secure repayment of any monies paid to or for Peter's sole benefit or for the plaintiff to seek to recover any such monies from them personally if the mortgage were found to be ineffective for this purpose.
21 The circumstances that attended the creation of the earlier mortgage over the property, that was discharged using funds provided by the plaintiff, were explored only briefly in evidence. However, no evidence established, and no submission was made to suggest, that the plaintiff was or should have been aware of any irregularity or impropriety that may have attended the creation of that liability or the transfer of a one third interest in the property to Peter. Mr and Mrs Siahos were therefore unable, and did not seek, to deny that the discharge of that liability by funds provided by the plaintiff was a benefit for which they remained liable to account to the plaintiff.
22 There is no evidence that the plaintiff was, or should have been, aware of any fraud or other irregular or suspicious conduct on the part of Peter. The loan documentation was in all respects valid on its face. There is no evidence to suggest that the plaintiff was, or should have been, aware that Peter was orchestrating a refinancing transaction using funds provided by the plaintiff taking security over the property that Mr and Mrs Siahos did not consent to or understand. The transaction was explained to Mr and Mrs Siahos by a chartered accountant, Ms Johnstone, upon whose certificate of explanation the plaintiff was entitled to rely. Whatever concern one might have about the efficacy of an explanation given over the telephone, probably to Mrs Siahos only, while she was in Greece and with a limited command of English, there is no suggestion that the plaintiff's concern about that should have been excited. Nor was there any reason for the plaintiff to suspect that the acknowledgment given by Mr and Mrs Siahos of legal advice given to them by Dimitrios Dialektos was anything other than what it purported to be.
23 Mr and Mrs Siahos submitted that because Nicholas Karefylakis made a written request to the plaintiff by letter dated 23 August 2005 to waive the plaintiff's usual requirement that the legal and financial aspects of the transaction be independently explained to them, the plaintiff was, or should have been, thereby put on notice that Peter was defrauding his parents or that the transaction was in some other way improper. The plaintiff denied Peter's request the following day in a letter in these terms:
"We confirm that we did seek further advice from our client regarding the waiver of the Special condition that Prokopios Siahos and Chrisoula Siahos obtain independent Legal and Financial advice as to the implications of entering into this transaction and advise that the Lender has NOT agreed to waive it.
