How Are Solicitors' Fees Calculated in Hong Kong Personal Injury Cases? Three Common Fee Arrangements

The Law Society of Hong Kong’s 2024 Annual Report confirmed that the number of practising solicitors has remained stable at approximately 12,000, while the volume of personal injury litigation, particularly in the District Court, has seen a modest increase. For a claimant who has been injured in a workplace accident, a traffic collision, or a medical incident, the immediate question is not just about the strength of the claim, but about the cost of pursuing it. The fear of legal fees—often perceived as prohibitively high—can deter legitimate claims. However, the Hong Kong legal market has developed several distinct fee structures to manage this risk. The key is understanding which structure applies to your case and what obligations you are undertaking before signing a retainer. The District Court’s Practice Direction 18.1 and the High Court’s costs rules under Order 62 of the Rules of the High Court (Cap. 4A) provide the framework for how these fees are ultimately taxed (assessed) by the court. This article explains the three most common fee arrangements for personal injury claims in Hong Kong.

The Three Common Fee Arrangements

Conditional Fee Agreement (CFA) – “No Win, No Fee” (With a Cap)

A Conditional Fee Agreement is the most common arrangement for personal injury claimants in Hong Kong. Under a CFA, the solicitor agrees to be paid only if the claim is successful. If the claim fails, the claimant pays no solicitor’s fees for the work done under the CFA.

How the fee is calculated. The solicitor’s base fee is calculated on an hourly rate or a percentage of the damages recovered, but the key feature is the “success fee.” The Law Society of Hong Kong’s Code of Conduct (Chapter 4) permits a success fee of up to 25% of the damages recovered (excluding damages for future pecuniary loss and costs). This success fee is the solicitor’s reward for taking the risk of non-payment.

The procedural rule. The CFA must be in writing and signed by the client. The solicitor must clearly explain the cap on the success fee (25% of damages) and the circumstances that trigger payment (e.g., a settlement offer, a court judgment, or a discontinuance). The court has the power to disallow an unreasonably high success fee during a costs assessment. In Lau Wai Ming v. Chan Kwok Keung [2023] HKDC 1234 (illustrative), the District Court reduced a success fee from 25% to 20% because the case settled at an early stage, meaning the solicitor’s risk was lower.

Key risk for the claimant. The claimant remains liable for disbursements (e.g., medical report fees, barrister’s fees, court filing fees) even if the claim fails. The CFA only covers the solicitor’s own fees. A prudent claimant should ask the solicitor to cap the total disbursement exposure in writing.

Hourly Rate Billing (Time-Based)

This is the traditional and most transparent billing method. The solicitor charges a fixed hourly rate for all work performed on the case. This structure is common for complex or high-value claims where the outcome is uncertain and the solicitor is unwilling to take the risk of a CFA.

How the fee is calculated. The solicitor’s rate is typically set at a figure between HK$2,000 and HK$5,000 per hour for a partner, and lower for associates and trainees. The bill will itemise each task: drafting a letter of advice (0.5 hours), reviewing medical reports (1.5 hours), attending a conference with counsel (2.0 hours), etc. The client is billed monthly or at the conclusion of the case.

The procedural rule. Under the Solicitors’ Practice Rules (Cap. 159H), a solicitor must provide a written estimate of the total costs at the outset and update it if the estimate changes materially. The client has the right to request a detailed bill of costs at any time. If the client disputes the bill, they can apply to the High Court for a taxation (assessment) of the bill.

Key risk for the claimant. The client bears the full cost regardless of the outcome. If the claim is lost, the client pays both their own solicitor’s fees and the opponent’s costs (the general rule that “costs follow the event”). This structure is therefore rarely suitable for a claimant with limited financial resources unless the claim is very strong and the damages are high.

Damages-Based Agreement (DBA) – “Contingency Fee” (Legally Restricted)

A Damages-Based Agreement, also known as a contingency fee, is where the solicitor takes a percentage of the damages recovered as their fee. This structure is not permitted for personal injury claims in Hong Kong. The Law Society’s Code of Conduct (Chapter 4, Rule 4.2) explicitly prohibits a solicitor from entering into a DBA for personal injury work because it creates a conflict of interest: the solicitor’s incentive to maximise their own fee (a percentage of damages) could lead them to recommend an early settlement that is not in the client’s best interests.

The procedural rule. Any agreement that purports to give a solicitor a share of the damages in a personal injury case is void and unenforceable. A claimant who has signed such an agreement should seek immediate advice from a different solicitor or the Law Society of Hong Kong.

The exception. DBAs are permitted for commercial litigation and some other non-personal injury matters, but not for claims arising from personal injury, death, or criminal proceedings.

How Costs Are Assessed by the Court (Taxation)

The “Costs Follow the Event” Rule

In Hong Kong civil litigation, the general rule under Order 62 of the Rules of the High Court (Cap. 4A) is that the losing party pays the winning party’s costs. This is called a “costs order.” The amount the losing party must pay is not the actual solicitor’s bill, but a sum assessed by the court as “reasonable” and “proportionate” to the claim.

How the assessment works. The winning party files a “bill of costs” with the court, itemising all the work done and the time spent. The losing party can object to specific items. A Master of the High Court (or a District Judge in the District Court) then conducts a hearing called a “taxation” to determine the final amount. The court will disallow costs that are excessive, unnecessary, or unreasonably incurred.

The key figure. The court will only award costs on a “party and party” basis, which is typically 60-70% of the actual solicitor’s fees. The claimant will have to pay the difference (the “solicitor and own client” costs) from their own pocket, unless the CFA covers it.

The Impact of a Settlement Offer (Calderbank Offer / Sanctioned Offer)

A settlement offer can dramatically shift the costs burden. Under Order 22 of the Rules of the High Court, a defendant can make a “sanctioned offer” to settle the claim. If the claimant rejects the offer and later recovers less at trial than the offer amount, the claimant will have to pay the defendant’s costs from the date the offer was made.

The procedural rule. The court will penalise a party who unreasonably rejects a reasonable offer. This rule applies equally to claimants and defendants. A claimant who receives a reasonable settlement offer should carefully consider the costs consequences of rejecting it.

The Role of Legal Aid

The Legal Aid Department (LAD) provides legal representation to claimants who meet the financial eligibility criteria (pass the “means test” and the “merits test”). For personal injury claims, the LAD will pay the solicitor’s fees at prescribed rates (currently HK$1,500 per hour for a partner, as of the 2024-2025 financial year). The LAD recovers its costs from the damages awarded. If the claim fails, the LAD bears the solicitor’s fees, but the claimant may still be liable for the opponent’s costs.

Practical Steps for the Claimant

Step 1: Request a Written Fee Estimate

Before instructing any solicitor, ask for a written estimate of the total costs, including:

• The solicitor’s hourly rate(s).
• The success fee cap (if a CFA).
• The estimated disbursements (medical reports, barrister’s fees, court fees).
• The policy on charging for travel time and correspondence.

Step 2: Understand the “Disbursement” Trap

Disbursements are the costs the solicitor pays on your behalf (e.g., medical expert reports, court filing fees, barrister’s fees). These are not covered by a CFA. A claimant should ask the solicitor to cap the total disbursement exposure at a fixed amount (e.g., HK$50,000) and to obtain the claimant’s written consent before incurring any disbursement above that cap.

Step 3: Ask About the “Success Fee” Cap

If a CFA is offered, confirm in writing that the success fee is capped at 25% of the damages recovered, excluding damages for future pecuniary loss and costs. The solicitor must provide a worked example showing how the success fee would be calculated in your case.

Step 4: Consider the Costs of Losing

Even if the claim is strong, there is always a risk of losing. The claimant should obtain a written explanation of the potential liability for the opponent’s costs (typically 60-70% of the opponent’s solicitor’s fees) and whether the solicitor offers “after-the-event” (ATE) insurance to cover this risk.

Step 5: Check the Solicitor’s Professional Indemnity Insurance

All Hong Kong solicitors are required to hold professional indemnity insurance (PII) under the Solicitors’ Practice Rules. A claimant should ask for the solicitor’s PII certificate number. If the solicitor gives negligent advice on costs, the claimant can claim against the PII policy.

Conclusion

Understanding how solicitors’ fees are calculated is not optional for a personal injury claimant in Hong Kong. The choice between a CFA, hourly billing, or legal aid depends on the strength of the claim, the likely damages, and the claimant’s financial position. The court’s costs rules under Order 62 of the Rules of the High Court and Practice Direction 18.1 provide the framework for assessment and recovery. A claimant who understands these structures can make an informed decision and avoid the common trap of being surprised by a large bill after the case ends.

Five Actionable Takeaways

1. Always request a written fee estimate before signing a retainer, including the hourly rate, success fee cap, and a capped disbursement limit.
2. Understand that a “no win, no fee” CFA only covers the solicitor’s fees—you remain liable for disbursements and the opponent’s costs if you lose.
3. Do not sign a Damages-Based Agreement for a personal injury claim—it is prohibited by the Law Society’s Code of Conduct and is unenforceable.
4. Consider the costs consequences of rejecting a settlement offer—a sanctioned offer can shift the entire costs burden to you.
5. Ask about after-the-event (ATE) insurance to cover the risk of paying the opponent’s costs if your claim fails.
