46 First, Mr Loel sent Chateau's Calderbank letter of 11 September 2009 to Dr and Mrs Zepinic at their address long before they were said to be in London and long before the termination of Mr Roskov's retainer. In the following terms the Calderbank letter of 11 September 2009 set out the history of the matter, referred to the contractual charging provision and the CTTT judgment for $370,847.35 and left an offer open for acceptance until 15 September 2009.
"3. In the circumstances, Chateau clearly has a caveatable interest as the chargee in respect of the moneys payable by you and your husband to it.
4. We note that you have not asserted that Chateau does not have a caveatable interest, that the caveat is invalid, vexatious or otherwise unsupportable nor that the caveat was improperly or irregularly registered.
5. On that basis, if our client applies to the Supreme Court of New South Wales for an order extending the operation of the Caveat, it is likely that the Court will make such an order.
6. We estimate that Chateau's costs of making such an application to the Court will be in excess of $5,000.00. If Chateau makes such an application to the Court and the Court makes an order extending the operation of the Caveat, Chateau will also seek an order that you pay its costs of, and incidental to, the application on an indemnity basis.
7. Chateau would prefer to resolve the issue without either party incurring further unnecessary costs. To that end, Chateau offers to resolve the issue on the following basis:
(a) you endorse the enclosed further caveat, with Chateau as the caveator, in respect of the Land with your consent (the "Further Caveat") and return the Further Caveat to us by 5:00pm on 15 September 2009;
(b) you undertake to do all things deemed necessary by Chateau to enable Chateau to lodge the Further Caveat by 3:00pm on 18 September 2009; and
(c) you undertake not to lodge with the Registrar-General any evidence whatsoever of the service of the Lapsing Notice."
47 Chateau's Calderbank letter claimed that in light of the short time available for making an application to the Court for extending the caveat that a reasonable period had been given to the Zepinics for accepting the offer. The letter further said that if the offer were not accepted Chateau would apply to the Court without further notice for an order extending the caveat.
