​

Paying party costs disputes arise where a receiving party’s bill of costs is excessive, poorly delegated, or disproportionate to the issues in the litigation. We act for insurers, local authorities and defendants across England & Wales in challenging bills of costs through Points of Dispute, proportionality arguments and detailed assessment proceedings.  These services relate to legal costs disputes governed by the Civil Procedure Rules in England & Wales.

What We Do for Paying Parties

​

We provide strategic support throughout the lifecycle of a costs dispute, including:

 

• Drafting Points of Dispute in detailed assessment proceedings

• Reviewing Replies and advising on negotiation strategy

• Proportionality, delegation and grade challenges

• Preparation for detailed assessment hearings and settlement negotiations

 

Challenging Bills of Costs

 

​A detailed bill of costs can contain hundreds or thousands of individual entries. Effective paying party strategy requires identifying the areas where reductions are most likely to be achieved. Hourly rates, grade allocation, duplication, and lack of delegation are common drivers of excessive costs. We analyse the bill line-by-line to identify:

​

• work falling outside the reasonable scope of the claim

• routine tasks billed at senior rates

• disproportionate time against value and complexity

• duplication between fee earners

These issues are then advanced through properly structured Points of Dispute supported by proportionality and necessity arguments.

​

Detailed Assessment Defence

​

Where costs cannot be agreed, disputes are resolved through detailed assessment proceedings under CPR Part 47. Paying parties must challenge the receiving party’s bill through structured Points of Dispute supported by evidence on proportionality, delegation, hourly rates and necessity.  Effective defence requires identifying the issues that will carry weight before the costs judge and focusing challenges accordingly.

 

Proportionality and Strategy

​

Effective paying party challenges do not focus on individual entries alone. The strongest outcomes arise where hourly rates, time claimed, and overall totals are linked to proportionality, conduct, and the actual requirements of the litigation.  This integrated approach frequently results in significant reductions prior to, or at, detailed assessment.

 

Acting Nationally for Paying Parties

​

We provide specialist costs lawyer and law costs draftsman services across England & Wales.  We act for local authorities, insurers, and private defendant in:

• detailed assessment proceedings

• negotiations following service of the bill

• fixed costs scope disputes

• guideline hourly rate challenges

 

Early involvement allows exposure to be assessed and strategy to be deployed before positions become entrenched.  Paying party costs disputes are rarely resolved by challenging isolated entries. The most effective strategy focuses on the issues that are likely to influence the outcome of detailed assessment, including proportionality, delegation, hourly rates and overall necessity. Early specialist involvement frequently results in substantial reductions before a matter proceeds to a contested hearing.
