“It's hard to quantify, right now. But at a guess, I'd say it's probably more than 50% faster, at times. It's literally that quick. We've found to be an essential practical tool. We're very satisfied.”

Detailed assessment proceedings meaning

Published by a LexisNexis Family expert
What does Detailed assessment proceedings mean?
The court process by which the amount of recoverable litigation costs is quantified after a costs order, usually requiring the losing party to pay the winner’s costs. In England and Wales, this is the detailed assessment regime under the civil procedure rules 1998 (SI 1998/3132), Part 47 and Practice Direction 47. The receiving party serves a notice of commencement and bill of costs; the paying party may serve points of dispute (within 21 days), with optional replies. Bills not exceeding £75,000 are usually dealt with by provisional assessment; otherwise there is a hearing before a costs judge or authorised court officer. Failures to engage can result in a default costs certificate. Costs are assessed on the standard or indemnity basis, subject to proportionality and reasonableness, and culminate in a costs certificate; interest generally runs from the costs order. The phrase is used chiefly in England and Wales. Equivalent processes exist but use different terminology: taxation of accounts before the Auditor of Court in Scotland; taxation before the Master (Taxing Office) in Northern Ireland; and adjudication of legal costs by the Office of the Legal Costs Adjudicators in Ireland (Legal Services Regulation Act 2015).

QOCS applies to detailed assessment in personal injury claims, limiting enforcement of defendants' Part 36 costs: Challis v Bradpiece [2024] EWHC 1124 (SCCO) (England and Wales)

Challis v Bradpiece [2024] EWHC 1124 (SCCO) What are the practical implications of this case? This appears to be the first judgment (so far as the writer is aware) to squarely consider whether qualified one-way costs shifting extends to detailed assessment proceedings. The ruling will assist claimant solicitors, who can now confidently tell clients that QOCS protection runs for the full duration of a personal injury claim. Those representing defendants are likely to be dismayed, as this removes a valuable bargaining lever, notably in matters where the principal claim was issued before the April 2023 revisions to the QOCS rules. As the hearing took place in the Supreme Court Costs Office, its precedential weight is, in most situations, persuasive rather than binding, and therefore does not rule out further challenges. Even so, the deputy costs judge undertook a comprehensive examination of the submissions and authorities, meaning that fresh, compelling grounds would probably be required to convince a court to disapply QOCS in later cases...

Appeals against costs orders under CPR 52: principles, procedure, permission and practicalities (England and Wales)

This Practice Notice explains what ought to be taken into account when considering an appeal against a costs order—the starting position being that such appeals are generally discouraged. It outlines the preliminary factors and the foundation for a costs-only appeal, which falls under CPR 52. It also covers the time limits for appealing, obtaining permission to appeal, challenging a refusal of permission, the correct venue for the appeal, the documents required to initiate it, and the consequences of bringing an appeal. This Practice Note does not consider: an appeal against the decision of a costs officer, as these are governed by special provisions in CPR 47.21 to CPR 47.24.

Interim payments on account of costs: applications, quantum and case law under the Civil Procedure Rules (CPR 44.2(8)), including budgeting, CFAs, Part 36 and stays (England and Wales)

This Practice Note examines what an interim payment on account of costs is, when the court may make such an order, and the presumption that an order will follow where a detailed assessment is anticipated. It also identifies what might constitute a good reason to displace that presumption when costs are to be assessed in detail. In addition, it reviews the relevant case law and considers the position both where costs budgeting has taken place and where it has not. What is an interim payment on account of costs? When the court orders the losing party to pay costs, the receiving party will not obtain payment until costs are agreed or a detailed assessment has concluded, a process that can take a considerable period. The general principle, stated in Mars UK Ltd v Teknowledge (1999), is that a successful party is entitled to their costs and should not be kept waiting for payment. In Grupo Hotelero Urvasco (2013), applying the underlying Mars principle, the judge confirmed that a...
