In
Safra v Wilmer Cutler Pickering Hale and Dorr LLP [2026] EWHC 703 (SCCO)
the former client sought detailed assessment of a bill of $35,343,213.96 – approximately £26 million.
The Judgment runs to 76 pages, and 423 paragraphs, and is an exhaustive analysis of the law in relation to a variety of Solicitors Act 1974 matters, including Contentious Business Agreements, fairness and reasonableness of such agreements, interim statutory bills, Chamberlain bills, special circumstances, and allocation of payments.
The defendant solicitors had delivered a large number of interim bills, and one of the issues was whether the bills were final statutory bills for the periods in question and thus, outside the time limit during which a client had an unqualified right to have the bills assessed, and related to that, if there were special circumstances justifying detailed assessment out of time.
The Senior Courts Costs Office held that the bills were not final statutory bills and thus, the client had an automatic right to have them assessed, but nevertheless, the court considered in detail the issue of special circumstances.
Each case will depend upon its facts, and in Issue 408 at Pages 137 – 138 I reported the case of
Biggar v Howard Kennedy LLP [2026] EWHC 132 (SCCO), under the heading
SOLICITORS ACT ASSESSMENT: NO COSTS UPDATES DID NOT AMOUNT TO SPECIAL CIRCUMSTANCES.
If a bill states that it is not the final and definitive bill for work done in that period, then it is very unlikely to be a final statutory bill – the wording tells its own story.
The court also held that the solicitors had failed to keep the client informed of costs, including two increases in hourly rates, and along with other matters, that would have justified assessment out of time under the special circumstances provision.
The court said that it had never seen a case where such a large bill had been supported by so little information.
It held that the firm’s invoices contained:
- charges which are so high as to raise concerns as to the costs incurred across the board.
The court also held that the solicitor’s letter of engagement contained too much uncertainty for the agreement to be a Contentious Business Agreement, significant facts being the failure to set a fixed fee, and the failure to have a mechanism by which the fees could be increased.
“The consultation and complaint provisions in the Engagement Letter do not alter its straightforward provision for the Defendant to increase its hourly rates by any amount and at any time it saw fit”.
There was accordingly a significant element of uncertainty with the Engagement Letter as to the hourly rates that the defendant would be charging from time to time.
The court said that this was wholly inconsistent with the proposition that the Engagement Letter was a Contentious Business Agreement.
Even if it had been a Contentious Business Agreement, the court would have set it aside as being unreasonable.
“If I had concluded that the Engagement Letter were, nonetheless, a CBA [Contentious Business Agreement], I would have found it to be unreasonable in providing for the Defendant’s hourly charging rates to be increased at times and by amounts dictated entirely by the Defendant, whilst simultaneously removing the Claimant’s rights, under section 70, to challenge those hourly rates”.
At Paragraphs 2 – 5, the court set out the issues to be dealt with:
2. The parties have identified a number of preliminary issues to be determined for the purposes of the Claimant’s application, and a consent order dated 5 March 2025 provided for the hearing of those issues.
3. Under the heading “The Nature of the Retainer” they are:
(a) Does the Engagement Letter dated 2 September 2022 constitute a contentious business agreement within the meaning of section 59 of the Solicitors Act 1974?
(b) If it does, was it fair and reasonable (and should it therefore be enforced or set aside)?
4. Under the heading “The Status of the Invoices” they are:
(c) Was the Defendant entitled to deliver interim statutory bills to the Claimant under the terms of the Engagement Letter?
(d) Did the Invoices, as delivered, amount to interim statutory bills (compliant with the express and implicit requirements of such bills)?
(e) In light of the answers to the above questions, when were the invoices (individually or collectively) delivered to the Claimant as a statutory bill or bills for the purposes of the Solicitors Act 1974?
5. Under the heading “Entitlement to Assessment” they are:
(f) When and to what extent have any statutory bills been paid for the purposes of s.70(4) of the Solicitors Act 1974 (if at all)?
(g) To the extent required, are there special circumstances to justify an order for assessment of the Invoices pursuant to s.70(3) of the Solicitors Act 1974?
(h) In light of the answers to all the questions above, should the court make an order for assessment of all or any of the Invoices, pursuant to the applicable provisions within Part III of the Solicitors Act 1974?
(i) If an order for assessment is to be made, should it be made subject to any conditions?
At Paragraphs 8 – 20, the court sets out the statutory provisions in relation to these matters, all which are contained in the Solicitors Act 1974.
Paragraphs 143 – 151, the court sets out the case law in relation to Contentious Business Agreements.
214. There was, accordingly, a significant element of uncertainty within the Engagement Letter as to the hourly rates the Defendant would be paying from time to time. That is wholly inconsistent with the proposition that the Engagement Letter was a CBA. My conclusion is that it was not.
That disposed of that aspect of the matter, but in Paragraphs 215 – 223, the court considered, obiter, and in case it was wrong, in finding that the Engagement Letter was not a Contentious Business Agreement, whether the Contentious Business Agreement was unfair and/or unreasonable.
The court quoted the well-known test set out in
Re Stuart ex p Cathcart [1893] 2 QB 201
“With regard to the fairness of such an agreement, it appears to me that this refers to the mode of obtaining the agreement, and that if a solicitor makes an agreement with a client who fully understands and appreciates that agreement that satisfies the requirement as to fairness. But the agreement must also be reasonable, and in determining whether it is so the matters covered by the expression “fair” cannot be re-introduced. As to this part of the requirements of the statute, I am of opinion that the meaning is that when an agreement is challenged the solicitor must not only satisfy the Court that the agreement was absolutely fair with regard to the way in which it was obtained, but must also satisfy the Court that the terms of that agreement are reasonable. If in the opinion of the Court they are not reasonable, having regard to the kind of work which the solicitor has to do under the agreement, the Court are bound to say that the solicitor, as an officer of the Court, has no right to an unreasonable payment for the work which he has done, and ought not to have made an agreement for remuneration in such a manner.”
222. If I had concluded that the Engagement Letter were, nonetheless, a CBA, I would have found it to be unreasonable in providing for the Defendant’s hourly charging rates to be increased at times and by amounts dictated entirely by the Defendant, whilst simultaneously removing the Claimant’s rights, under section 70, to challenge those hourly rates.
223. I would, accordingly, have concluded that the Engagement Letter (had it been a CBA) should be set aside as unreasonable, and that the Defendant’s billed costs should be assessed in their entirety.
At Paragraphs 224 – 250, the court considered the question of whether the defendant was entitled to deliver Interim Statutory Bills under the terms of the Engagement Letter.
The starting point is that there is no such right.
The court held that there was although there was such a contractual right in this case.
At Paragraphs 251 – 282, the court considered whether the invoices as delivered amounted to final Interim Statutory Bills.
266. The standard wording on the Defendant’s finalised (and draft) invoices is, however, materially different in that, as the Claimant points out, each monthly invoice “Includes only Services and disbursements posted to date.”
257. The clear meaning of that phrase is that some of the work performed by the Defendant during the period covered by each invoice might not have been “posted”, in other words recorded upon the Defendant’s systems, at the time of delivery and accordingly might have to be included in a subsequent invoice. In other words, none of the finalised invoices are stated to be final for the period they cover: quite the contrary.
268. The Defendant attempts to interpret this phrase only as an indication that further charges may be rendered for work undertaken in the subsequent month. That does not seem to me to be a viable interpretation. There is no reason why an invoice covering work undertaken during a specified period should incorporate a redundant warning to the effect that that the solicitor will charge for further work undertaken during a subsequent period.
Chamberlain Bills
283. To explain my conclusions in this respect I need to refer to the concept of a “Chamberlain bill”. A Chamberlain bill is a series of non-statutory bills which together become a statute bill upon delivery of the last bill (Chamberlain v Boodle & King). A series of bills which, individually, do not qualify as statutory bills can nonetheless collectively comprise a Chamberlain bill (Bari v Rosen, Spencer J, at paragraph 52-59).
284. The Defendant’s case is that all of its finalised invoices, being statutory bills, were delivered on the dates shown in the schedule reproduced at paragraph 60 above.
285. The Defendant however accepts that if the Defendant’s finalised invoices were not, individually, statutory bills, then as the Claimant says, the complete series of non-statutory bills delivered by the Defendant to the Claimant together comprised a statutory “Chamberlain bill”, delivered on 17 September 2024, consistently with the terms of the letter of 16 September 2024 sent to the Claimant by Mr Born and Mr Trenor.
286. Given the conclusions I have already reached, that is the only conclusion open to me. The effective date of delivery of a statutory bill to the Claimant by the Defendant was 17 September 2024.
When And to What Extent Have Any Statutory Bills Been Paid for the Purposes of Section 70(4), Solicitors Act 1974?
Given that the court found that the interim bills were not statutory bills, the court did not need to consider these issues for the purposes of this decision, but did so, in detail, and setting out the case law in detail, and this is at Paragraphs 287 – 328.
The points to note are that partly paid bills for the purposes of Section 70, are treated as unpaid bills.
Monies paid into an overdrawn account are set against, and extinguished, the earliest debts first.
Special Circumstances
329. Because I have concluded that the Defendant’s invoices together represented a part-paid Chamberlain bill delivered on 17 September 2024, and because the Claimant applied for the assessment of that bill on 17 December 2024, section 70(2) applies and special circumstances are not required before an order for the assessment of that bill can be made. Again however I will explain what my conclusions would have been, had I found that the Defendant’s invoices were interim statute bills.
The court then dealt with this issue in detail with an extensive analysis of the case law, at Paragraphs 330 – 408.
The court would have found special circumstances justifying assessment of the bill out of time.
404. I have not previously encountered a case in which such levels of costs accrued with such limited information being provided to the client. The Defendant’s failure to notify the Claimant of its hourly rate increases seems symptomatic of a lack of awareness of the importance of keeping the client fully informed of the costs position. However much he would have known about what was being done for him, and however pleased he may have been at the level of service provided, the Claimant was not regularly being kept aware of what it was costing him. That would have been unsatisfactory even if the fees finally billed had not been so far in excess of what he had clearly indicated that he could afford.
408. For those reasons, had it been appropriate, I would have certified that there were, in this case, special circumstances that would have justified an order for the assessment of such statutory bills as fell within section 70(3).
Summary of Key Conclusions
416. The Engagement Letter between the Claimant and the Defendant, as signed on 2 September 2022 and amended on 25 September 2023, was not a Contentious Business Agreement (CBA). Its unilateral, open-ended provisions for hourly rate increases, the amounts and timing of which were entirely at the discretion of the Defendant, are inconsistent with the requisite characteristic of certainty.
417. If I had found that the Engagement Letter was a CBA, I would have set it aside as unreasonable because it incorporated those unilateral, open-ended review provisions whilst (as a CBA) preventing the Claimant, on any assessment, from challenging any increased hourly rates, whatever they might have been.
418. The Engagement Letter did allow for the Defendant to deliver interim statutory bills to the Claimant in the course of the Defendant’s retainer.
419. The invoices actually delivered were not, however, interim statutory bills, because they lacked the requisite element of finality.
420. The invoices collectively, as a series, comprised a single Chamberlain bill delivered to the Claimant by the Defendant on 17 September.
421. The Claimant’s application for detailed assessment having been made on 17 December 2024, this court has jurisdiction to order an assessment of the Chamberlain bill under section 70(2) of the Solicitors Act 1974.
422. Given that Defendant’s invoices were not interim statute bills, it is not necessary for the Claimant to establish that special circumstances justify an order for assessment of such of them as would otherwise have fallen within section 70(3). If it had been necessary, I would have found that special circumstances do apply.
423. I find it to be appropriate to make an order for assessment, under section 70(2), of the Chamberlain bill delivered by the Defendant to the Claimant on 17 September. I do not find it to be appropriate to attach any conditions to that order.
COMMENT
This is one of the most exhaustive and detailed Judgments in recent times of these Solicitors Act 1974 matters, although much of the Judgment is obiter, as it was not necessary for the decision in the case, the Judgment as a whole is of great assistance.
