DECISION
32 In my opinion, notice of a lien can be effectively given at a time when the interest is still inchoate, in that there has not yet been a judgment or settlement to which the lien could attach. The important matter is the actual or presumed state of mind of the person dealing with the property at the time when that dealing takes place: if the person in question has notice of the lien at the time the property is dealt with, that will be sufficient, and it will not matter that the communication occurred at a time before the lien attached to particular property. I think this follows as a matter of principle concerning the circumstances in which persons can be bound by notice of equitable interests, and it is also assumed in some of the cases, including the leading case of Welsh v. Hole. In my opinion, the contrary view suggested by Johnstone v. Cox and Re Dallas is not applicable, because those cases were concerned with questions of priority; and held merely that a notice of an assignment of a future equitable interest, given before that interest actually arose, could not give priority over an assignment of that interest of which notice was given after the equitable interest in question arose.
33 In my opinion, it follows from this approach that the adequacy of the notice must be considered as at the time when the challenged dealing takes place; and the question whether a notice is sufficient to bring about the required actual or presumed state of mind must have regard, not only to the terms of the notice itself and the circumstances in which it was given, but also to the circumstances that have ensued in the meantime. I accept Mr. Brereton's submission that the change of solicitors would not of itself do away with notice imputed to the respondent through his previous solicitors; but the change of solicitors is a circumstance to be taken into account in determining whether the notice should be considered as being effective as at the time of the challenged dealing, that is in May 1993.
34 I noted a submission by Mr. Whittle that constructive notice was not sufficient, but I did not understand Mr. Whittle to submit that imputed notice was not sufficient. There is a suggestion in Ross v. Buxton (1889) 42 Ch. 190 at 202 that imputed notice might not be sufficient; but I will proceed on the assumption that it is.
35 In my opinion, the cases of Lloyd v. Banks, William Brandt's and James Talcott, referred to by Mr. Whittle, do confirm that notice of an assignment should be such as to convey to the recipient, not merely the possibility that an assignment may have occurred, but the fact that it has. In relation to a solicitor's lien, in my opinion, the notice must, viewed in all the circumstances occurring up to the time of the dealing with the affected property, be such as to convey to the recipient as at that time that a lien is being asserted in respect of costs incurred in the relevant matter and unpaid. It is not sufficient that it merely raise a possibility that such is the case.
36 In my opinion, the authority and accompanying letter sent to the respondent's solicitor in October 1989 did not have the clarity necessary to fix the respondent with notice of the appellant's lien in May 1993. As has been noted, the document itself made no reference to costs or to a lien, and in particular did not suggest that there were then any costs incurred in the matter which were owing, or assert that it was anticipated that there would be costs incurred in the proceedings which would need to be paid out of the property in question. It is true, as asserted by Mr. Brereton, that the reference to the authority being irrevocable and for valuable consideration, and the reference to the need for written consent of the appellants for the authority to be cancelled, strongly suggests that the solicitors were seeking to protect some interest of their own; and that, although that interest could arise from other dealings such as loans or work on other matters, it is likely that the interest would include costs incurred in the particular proceedings. However, when in April 1992 the appellants ceased to act for the respondent's wife, it did in my opinion become objectively unlikely that they would be the persons to whom the whole of any verdict or settlement would be paid; and the authority in its terms only referred to the whole of such moneys, not to any part referable to costs. Furthermore, at no time during the three and a half year period after the authority was sent was any notice given by the appellants to the respondent that there were unpaid costs which could support a lien or that any lien continued to be asserted, notwithstanding ample opportunities to do so, including the conversations in April 1993.
37 It is true, as submitted by Mr. Brereton, that Mr. Hahn conceded that, at the time of those telephone conversations, it must have occurred to him that the appellants' only remaining interest in the matter was their costs; and that he would have presumed that they were looking to be paid their costs out of the proceeds of sale of the Lane Cove property. However, in my opinion the circumstance that that matter must have occurred to Mr. Hahn, and that he would have made that presumption, does not convert those conversations into any kind of notice either to Mr. Hahn or to the respondent that the appellants were asserting that there were costs owing to them in respect of which they had a lien over the proceeds of the judgment.
38 The failure of the appellants to convey their claim to Mr. Hahn during these conversations, or indeed at any other time, could well have amounted to laches; but that defence was never raised and could not be given effect to. However, in my opinion, it is also a circumstance very relevant to the question whether the document sent to the respondent's previous solicitors three and a half years earlier was sufficient to fix the respondent with notice of a lien in May 1993.
39 Having regard to all the circumstances I have outlined, my opinion is that the document provided in October 1989 was not such as, in the circumstances that existed in May 1993, to give the respondent notice that the appellants claimed a lien for outstanding costs and disbursements over the proceeds of the judgment.
40 For those reasons, in my opinion the appeal should be dismissed with costs.
41 FOSTER AJA: I agree with Hodgson JA.
