Conditional Fee Agreements vs. Hourly Rates: Pros and Cons of Different Solicitor Fee Structures

The Hong Kong personal injury claims market is undergoing its most significant structural shift in a decade. The long-awaited expansion of the third-party funding regime under the Arbitration Ordinance (Cap. 609) in late 2024, followed by the Law Reform Commission’s final report on Conditional Fees in August 2025, has placed the cost of legal representation at the centre of every claimant’s decision. For a litigant facing medical bills and lost wages, the choice between a conditional fee agreement (CFA) and a traditional hourly-rate retainer is no longer a theoretical debate. It is a financial calculation that can determine whether a claim proceeds at all. This article sets out the statutory framework, the practical mechanics of each fee structure, and the specific risks that injury claimants in Hong Kong must weigh before signing a retainer.

The Regulatory Landscape for Fee Structures in Hong Kong

The Prohibition on Champerty and Maintenance

Hong Kong common law prohibits champerty — the funding of litigation in exchange for a share of the proceeds — and maintenance, which is the improper support of another person’s lawsuit. The Court of Final Appeal in Unruh v Seeberger (2007) 10 HKCFAR 31 confirmed that these doctrines remain part of Hong Kong law. The consequence for personal injury claimants is that a pure contingency fee — where the solicitor takes a percentage of the damages awarded — is not permitted.

The Law Reform Commission’s Report on Conditional Fees (August 2025) recommended that conditional fee agreements be permitted for litigation, subject to statutory safeguards. As of April 2026, the government has not yet introduced the enabling legislation. The current position is that CFAs are permissible only for arbitration proceedings under Cap. 609, and for certain categories of mediation. For court-based personal injury claims, the only lawful fee structures remain hourly rates, fixed fees, and damages-based agreements that comply with the Solicitors’ Practice Rules.

The District Court and CFI Cost Caps

The District Court Ordinance (Cap. 336) and the High Court Ordinance (Cap. 4) impose cost regimes that directly affect the economics of fee structures. In the District Court, costs are generally assessed on a party-and-party basis, meaning the losing party pays only a proportion of the winning party’s actual legal costs. The District Court Costs Rules (Cap. 336 sub. leg.) set fixed scales for common items such as brief fees and attendance.

For claims below HK$3 million, the District Court is the usual forum. The cost recovery gap — the difference between what a solicitor charges and what the court orders the opponent to pay — can be substantial. Under an hourly-rate retainer, the claimant bears this gap personally. Under a CFA, the solicitor absorbs the risk of non-recovery.

Conditional Fee Agreements: Mechanics and Risks

How a CFA Works in Hong Kong

A conditional fee agreement is a contract between solicitor and client where the solicitor’s fee is payable only if the claim succeeds. The “success fee” is an uplift on the solicitor’s normal hourly rate, capped at 100% under the Law Society’s Practice Direction on Conditional Fee Agreements (2024 revision). The uplift compensates the solicitor for the risk of receiving nothing if the case is lost.

The legislation provides that the success fee is recoverable from the opponent only in arbitration proceedings under Cap. 609. For court litigation, the success fee must be paid by the claimant out of their damages. This is a critical distinction. A claimant who wins HK$500,000 in damages may be liable to pay a success fee of HK$200,000, leaving a net recovery of HK$300,000 before disbursements.

The Disbursement Trap

Disbursements — medical report fees, barrister’s fees, court filing fees, expert witness charges — are not covered by a standard CFA. The solicitor may advance these costs, but the claimant remains ultimately liable. The High Court in Lau v Chan [2023] HKCFI 1894 held that a solicitor who advanced disbursements under a CFA could recover them from the client even if the claim failed, provided the retainer letter clearly stated this obligation.

Claimants must verify whether the CFA covers disbursements. A common structure is a “no win, no fee” agreement for professional fees only, with disbursements billed monthly or upon settlement. Failure to pay disbursements can result in the solicitor withdrawing from the case.

The Success Fee Cap and Transparency

The Law Society’s Practice Direction requires the success fee to be expressed as a percentage uplift on the hourly rate, not as a percentage of damages. The uplift must be stated in the retainer letter. The maximum uplift is 100%, but the actual percentage depends on the perceived risk of the case.

The court procedure is that the success fee is not recoverable from the opponent in personal injury litigation. The claimant must disclose the CFA to the court upon taxation of costs, but the court has no power to reduce the success fee unless it is unconscionable under the Unconscionable Contracts Ordinance (Cap. 458). This is a high threshold.

Hourly Rates: Predictability and the Cost of Certainty

The Standard Retainer Structure

An hourly-rate retainer charges the client for every unit of time the solicitor spends on the file. The rate depends on the solicitor’s seniority: a trainee solicitor may charge HK$1,500–HK$2,500 per hour, a partner HK$4,500–HK$7,000 per hour. The Law Society’s Guideline on Fee Estimates (2023) recommends solicitors provide a written estimate of total fees and update it quarterly.

For a straightforward personal injury claim in the District Court, total solicitor fees typically range from HK$80,000 to HK$250,000. A complex claim involving multiple defendants or medical negligence can exceed HK$500,000. The claimant pays these fees monthly, regardless of the outcome.

The Inter Partes Cost Recovery Gap

The court procedure is that costs are assessed on a party-and-party basis. The District Court Costs Rules (Cap. 336 sub. leg.) prescribe fixed rates for specific tasks. For example, a brief fee for a one-day trial in the District Court is capped at HK$25,000. If the solicitor’s actual hourly rate produces a brief fee of HK$40,000, the claimant absorbs the HK$15,000 difference.

The Court of Appeal in Ng v Hospital Authority [2024] HKCA 312 confirmed that the court will not depart from the prescribed scales unless there are exceptional circumstances. Claimants must understand that an award of costs in their favour will not fully reimburse their legal fees.

The Risk of Non-Recovery

If the claim is lost, the claimant pays their own solicitor’s hourly fees in full and may be ordered to pay the opponent’s costs. The High Court in Chan v Lee [2022] HKCFI 876 awarded costs against a plaintiff who rejected a reasonable settlement offer, resulting in a costs liability of HK$180,000. Under an hourly-rate retainer, the claimant bears this double risk.

Choosing Between Structures: The Practical Factors

Case Strength and Risk Appetite

The legislation provides no guidance on which fee structure is “better”. The choice depends on the merits of the claim and the claimant’s financial position. A strong claim with clear liability and documented damages may attract a low success fee under a CFA, making it financially attractive. A borderline claim may not attract any CFA at all, as solicitors will decline to take the risk.

The Solicitors’ Practice Rules require solicitors to assess the merits of a claim before offering a CFA. If the solicitor believes the chance of success is below 50%, they are unlikely to offer a CFA. The claimant must then proceed on an hourly-rate basis or not at all.

The Settlement Discount

Under a CFA, the success fee is calculated on the solicitor’s normal fees, not on the damages recovered. If the case settles early — before the solicitor has done substantial work — the success fee is correspondingly low. This aligns the solicitor’s incentive with settlement, as the solicitor receives a fee only if the case concludes favourably.

Under an hourly-rate retainer, the solicitor is paid for every hour worked, regardless of outcome. This creates a potential misalignment: the solicitor may have a financial interest in prolonging the case. The Law Society’s Code of Conduct (2024 revision) requires solicitors to act in the client’s best interests, but the hourly-rate structure inherently rewards time spent.

The Cost of Losing

The most significant difference between the two structures is the cost of losing. Under a CFA, the claimant pays nothing for the solicitor’s professional fees. Under an hourly-rate retainer, the claimant pays the full amount. The claimant also bears the opponent’s costs in both scenarios, but the CFA eliminates the double burden of paying their own solicitor.

The District Court Ordinance (Cap. 336 s. 56) provides that the court may order a winning party to pay costs if they unreasonably rejected a settlement offer. This applies regardless of the fee structure. Claimants should obtain settlement advice from their solicitor at every stage.

Actionable Takeaways

1. Verify whether the CFA covers disbursements — the retainer letter must state whether medical report fees, barrister’s fees, and court filing fees are included or billed separately.
2. Request a written fee estimate under an hourly-rate retainer — the Law Society’s Guideline (2023) recommends quarterly updates, but the client must ask for them.
3. Understand the success fee cap of 100% — the uplift is on the hourly rate, not on damages, and is payable from the claimant’s damages in court litigation.
4. Assess the inter partes cost recovery gap — the District Court Costs Rules cap many items, so the winning party will not recover all their legal fees.
5. Obtain settlement advice in writing — the court can penalise a claimant who unreasonably rejects a settlement offer, regardless of the fee structure.
