The Answer in 60 Seconds

Subrogation is the process by which an insurer, having indemnified the SME for a loss, steps into the SME's rights and pursues recovery against any third party legally responsible for the loss. The principle is codified for marine insurance in section 79 of the Marine Insurance Act 1906 and applies more broadly as a matter of standard policy wording across Singapore non-marine covers. The standard subrogation case in Singapore is Sompo Insurance Singapore Pte Ltd v RSA Insurance Group plc [2021] SGHC 152, in which Sompo (as the insurer) sought recovery from a counterparty under subrogation principles. The SME's role in subrogation is largely passive - cooperate with the insurer's recovery action, preserve relevant evidence, and avoid waiving rights against third parties that would prejudice the insurer's recovery. This article sets out how subrogation operates, the SME's obligations, and the practical implications for vendor and customer contracts where subrogation rights may have been waived.

The Sourced Detail

Subrogation is one of the structural pillars of insurance, ensuring that:

  • The SME is not under-indemnified (the SME recovers what was lost).
  • The SME is not over-indemnified (the SME does not recover twice - once from the insurer and once from the responsible third party).
  • The responsible third party is not let off (the loss falls on the party legally responsible).

The principle has a long common-law pedigree - foundational English cases like Castellain v Preston (1883) - and operates in Singapore through both statutory and policy-wording routes.

The statutory route - Marine Insurance Act 1906

Section 79 of the Marine Insurance Act 1906 codifies subrogation for marine insurance: where the insurer pays for a total loss, the insurer is entitled to take over the interest of the insured in whatever may remain of the subject-matter so paid for; and the insurer is subrogated to all the rights and remedies of the insured in respect of the subject-matter from the time of the casualty causing the loss.

The principle applies by analogy to non-marine insurance through the standard policy wording.

The policy-wording route

Standard Singapore non-life commercial policies include a subrogation clause that:

  • Vests in the insurer the right to take action in the SME's name to recover from any responsible third party.
  • Requires the SME to cooperate with the insurer's recovery action.
  • Prohibits the SME from waiving rights against third parties without the insurer's consent (typically with carve-outs for normal-course commercial arrangements).
  • Allocates any recovery between the insurer (up to the amount paid) and the SME (any excess, plus typically the SME's deductible).

The recurring Singapore authority

The audit-memory-confirmed Singapore authority on subrogation is Sompo Insurance Singapore Pte Ltd v RSA Insurance Group plc [2021] SGHC 152. In that case, Sompo (as the insurer that had paid out a claim) brought a subrogation action against RSA, advancing the principles of subrogation in a context involving overlapping cover arrangements. The case is the standard reference for modern Singapore subrogation practice.

Other Singapore authority on subrogation principles includes the older line of cases applying the common-law framework.

Where subrogation matters operationally

Three operational scenarios where subrogation engagement is critical.

Scenario 1: Fire caused by a contractor's negligence. A contractor working on the SME's premises causes a fire through negligent welding. The SME's property insurer pays the property loss. The insurer then exercises subrogation against the contractor (and the contractor's PL insurer). The SME's role is to preserve the evidence (the contractor's identity, the work-order documentation, the cause-of-fire investigation) for the insurer's recovery action.

Scenario 2: Customer injury caused by a supplier's defective product. A customer is injured by a product the SME supplied; the SME's product-liability cover pays the customer's claim; the insurer subrogates against the product manufacturer.

Scenario 3: Cyber loss caused by a vendor's breach. A vendor's data breach exposes the SME's customer data; the SME's cyber cover pays the response and notification costs; the cyber insurer subrogates against the vendor.

In each scenario, the SME's evidence preservation, contract documentation, and cooperation with the insurer's recovery action determine the success of the subrogation.

The "waiver of subrogation" issue

A standard commercial contract may include a "waiver of subrogation" clause - the SME agrees that, in the event of a loss caused by the counterparty, the SME's insurer waives its subrogation rights against the counterparty.

Waivers of subrogation are common in:

  • Lease agreements - landlord-tenant mutual waivers are standard.
  • Construction contracts - the JCT, FIDIC, and PSSCOC standard forms include waivers.
  • Customer contracts - sometimes negotiated by larger customers.
  • Vendor contracts - sometimes negotiated by larger vendors.

The waiver binds the SME's insurer only if the policy wording permits the SME to waive, or if the insurer is notified and accepts. Standard wording typically permits the SME to enter into waivers in the normal course of commercial arrangements, but the insurer should be on notice of any material waiver.

Three practical implications:

  • Read the policy's position on waivers before signing any contract with a waiver clause.
  • Notify the insurer of material waivers (typically with the next renewal or sooner if material).
  • Maintain a register of contracts containing waivers, in the seven-folder structure.

The deductible question

Where the insurer recovers from a third party, the recovery typically reimburses the insurer first (up to the amount paid), then the SME (for any excess and, depending on the wording, the deductible).

A subrogation recovery may not always include the SME's deductible. The policy wording determines whether the deductible portion of any recovery flows to the SME or remains with the insurer.

The "made whole" principle

The general principle, articulated in Castellain v Preston (1883), is that the SME is entitled to be made whole before the insurer takes the subrogation recovery. Where the insurer's payment was less than the SME's full loss (because of the deductible, sub-limit, or policy limit), and a subrogation recovery is obtained, the SME's residual loss may be entitled to first claim on the recovery.

The "made whole" principle interacts with the policy's subrogation clause; the policy wording governs the specific allocation.

The SME's obligations

The SME's obligations under a subrogation clause typically include:

  1. Cooperate fully with the insurer's recovery action - provide documents, witnesses, and statements.
  2. Preserve evidence of the loss and of the responsible third party's involvement.
  3. Not prejudice the insurer's recovery rights by waiving claims against third parties without consent.
  4. Account for any direct recovery from a responsible third party (the recovery may need to be paid over to the insurer).
  5. Continue any limitation-period preservation action (writs, demand letters) to prevent the claim against the third party from being time-barred.

When subrogation does not engage

Subrogation does not engage in three scenarios:

  • Loss caused entirely by the SME - no responsible third party.
  • Loss caused by a co-insured under the same policy - the insurer typically cannot pursue its own insured.
  • Loss subject to a waiver of subrogation that the insurer is bound by.

In each case, the insurer's payment is the SME's total recovery; the matter ends there.

Common Mistakes / What Goes Wrong

  1. Signing contracts with waivers of subrogation without checking the policy position.

  2. No notification to insurer of material waivers.

  3. Direct settlement with a responsible third party without insurer consent. May prejudice the insurer's position.

  4. Evidence not preserved for the insurer's recovery action.

  5. Not maintaining the limitation-period clock on the third-party claim.

  6. Misunderstanding the "made whole" principle. The SME's residual loss may be entitled to first claim on a recovery.

  7. No register of contracts with waivers. Unknown waivers may surface at claim time.

  8. Deductible recovery position not understood. The wording governs.

  9. Subrogation declaration delayed to insurer.

  10. No coordination between the SME's solicitors and the insurer's in any direct litigation.

What This Means for Your Business

  1. Read every commercial contract for waiver-of-subrogation clauses before signing.

  2. Notify the insurer of any material waiver, ideally at policy renewal.

  3. Maintain a register of contracts containing waivers in the seven-folder structure.

  4. Preserve evidence of any loss and of the responsible third party's involvement.

  5. Cooperate fully with the insurer's recovery action.

  6. Do not settle directly with a responsible third party without insurer consent.

  7. Understand the "made whole" principle for your specific policy wording.

  8. Coordinate solicitor engagement between SME and insurer where the SME has direct counsel.

Questions to Ask Your Adviser

  1. For our current policies, what is the subrogation clause's position on waivers?
  2. What is the "made whole" position - if a recovery is obtained, how does it flow between us and the insurer?
  3. For our recent lease and supplier contracts, do they contain waivers of subrogation, and have they been notified?
  4. If we suffer a loss that may have a third-party cause, what is the insurer's recovery support model?
  5. For our deductible, does it form part of a subrogation recovery?
