How Calderbank Offers Can Save Time and Money in Legal Disputes
Reaching an early settlement in legal disputes can save both time and money. One effective method for achieving such settlements is through a Calderbank offer. This article will explain the concept of a Calderbank offer, its workings, implications, and the best practices for making and responding to such offers.
What is a Calderbank Offer?
A Calderbank offer is a settlement proposal made by one party to another during a legal dispute. It’s named after the English Court of Appeal decision in Calderbank v Calderbank. This offer is typically made “without prejudice save as to costs,” meaning it can’t be used against the offering party in the leading legal proceedings. Still, it can be referred to when deciding who should pay the legal costs if the case proceeds to trial.
The primary aim of a Calderbank offer is to encourage negotiation and resolution outside of court, thereby saving time and costs. If the offer is rejected and the final judgment is less favourable than the offer made, the offering party may be entitled to recover their fees from the date of the offer onwards. This incentivises parties to consider reasonable settlement offers seriously and discourages the unreasonable rejection of such offers.
Calderbank offers are typically made in writing and include specific details such as the proposed settlement amount, terms, and a deadline for acceptance. They can be used before or during litigation but must be made before the judgment is delivered.

How Does a Calderbank Offer Work?
Either party in a dispute can make a Calderbank offer before the case goes to trial. This is done through a written document known as a Calderbank letter. If the offer is rejected and the case proceeds to court, the court can take it into account when deciding on costs. Typically, the losing party pays the costs. However, if a Calderbank offer was unreasonably rejected, the court might order indemnity costs, allowing the party who made the offer to recover a portion of their costs.
Implications of Rejecting a Calderbank Offer
If a Calderbank offer is unreasonably rejected, the rejecting party may face an indemnity cost order, which means they might have to pay a higher proportion of the other party’s legal costs. The court will evaluate whether the offer was genuine and the rejection was unreasonable.
What is Included in a Calderbank Letter?
A well-drafted Calderbank letter should include the following:
A statement that the offer is ‘without prejudice save as to costs.- A reference to the principles derived from Calderbank v Calderbank.
- A clear statement that the offer may be used in court for an indemnity cost application.
- A specified time frame for acceptance, providing sufficient time.
- Reasons why the offer should be accepted.
- Clear, precise, and specific terms.
- Evidence of a genuine compromise.
Benefits of a Calderbank Offer
There are several benefits to using a Calderbank offer:
- Cost Reduction: It encourages settlement, potentially avoiding the costs associated with litigation.
- Cost Recovery: If the offer is rejected, the party who made it may recover part of their costs.
- Early Resolution: Promotes quick dispute resolution, saving time and resources.
- Strategic Advantage: Can influence cost decisions without guaranteeing an indemnity cost order.
Examples and Case Studies
Example:
Luca is in a legal dispute with Finn over a contract breach. Finn offers Luca $50,000 to resolve the dispute, sending this as a Calderbank letter. Luca refuses, as she seeks $90,000. The matter goes to trial, and Luca is awarded only $25,000. Because Finn’s offer was more favourable than the trial outcome, Finn can claim costs, arguing that Luca unreasonably rejected his reasonable offer.
Case Study:
In the 2021 case of Barboza v Blundy & Others [2021] QSC 82, the court emphasised the importance of Calderbank offers. The case highlighted how an unreasonably rejected Calderbank offer could significantly impact cost orders, reinforcing the necessity of carefully considering such offers.
Is a Calderbank Offer the Same as an Offer of Compromise?
A Calderbank offer is not the same as an offer of compromise. While both aim to sanction unreasonable rejection of settlement offers, they differ in how they impact costs. A Calderbank offer leaves costs to the court’s discretion, whereas an offer of compromise provides more predictability and certainty regarding costs.
Understanding Indemnity Costs
Indemnity costs are the justifiable legal expenses a party accumulates over the course of litigation. These typically encompass a variety of legal expenditures, such as:
- Professional fees
- General charges
- Out-of-pocket expenses
- Remuneration
A Practical Example
Imagine a former staff member takes legal action against you, claiming unfair dismissal. To resolve the matter, you present a fair out-of-court settlement, but the employee rejects it.
If the case goes to trial and the judge awards the employee an outcome very similar to the settlement you originally offered, you can use that prior offer to your advantage. You can argue that the former employee needlessly prolonged the legal process by dismissing a fair resolution early on. Consequently, the court may rule that the employee is responsible for covering both their own legal fees and yours.
Notable Case Examples and Figures
A 6-Day Offer Window: The Queensland Supreme Court ruled that dismissing a Calderbank offer that was open for just six days was unjustified, ultimately awarding indemnity costs to the offering party.

A $20,000 Cost Claim: Following the rejection of a Calderbank offer, a litigant in a Fair Work Commission matter applied to recover $20,000 in costs.
Reference: Fair Work Commission Decision 2024 FWC 3363
A $900,000 Settlement Dispute: The NSW Supreme Court analysed a $900,000 settlement proposal, demonstrating how critical precise drafting is if a party wants to successfully trigger indemnity cost protections.
