Duty To Mitigate Loss
Duty to Mitigate Loss: Overview
The duty to mitigate loss is a fundamental principle in both contract law and commercial arbitration. It requires a party suffering a loss due to a breach of contract or wrongful act to take reasonable steps to reduce or minimize the loss.
Key Principle:
- The party cannot recover losses that could have been reasonably avoided.
- Failure to mitigate may reduce damages awarded, but it does not absolve the breaching party from liability.
This principle is widely recognized in Singapore, the UK, and international arbitration practice.
Elements of the Duty to Mitigate
- Knowledge of Breach – The non-breaching party must be aware of the breach or wrongful act.
- Reasonable Steps – Steps taken must be reasonable and commercially prudent under the circumstances.
- Causation – Losses avoided or reduced cannot be claimed as damages.
- Proportionality – Mitigation does not require extraordinary or impractical measures.
Key Insight: The duty is reactive, not proactive; it arises only once the breach has occurred or is imminent.
Applications
- Commercial Contracts – Reducing loss by sourcing alternative suppliers, minimizing delay costs, or reselling goods.
- Construction Contracts – Mitigating delay or disruption costs by adjusting workflow or hiring additional resources.
- Employment Contracts – Finding alternative employment to reduce lost wages after wrongful termination.
- Insurance and Finance – Taking reasonable steps to limit exposure after a loss or market fluctuation.
