What term describes a provision that limits an insurer's liability to a proportional share of an insured loss when other insurance is present?

The term that describes a provision limiting an insurer's liability to a proportional share of an insured loss when other insurance is in place is known as the Pro-Rata liability provision. This provision ensures that when multiple insurance policies cover the same risk or loss, each insurer pays a portion of the claim based on their respective coverage amounts. This helps prevent the insured from receiving a total payment that exceeds the actual loss suffered, encouraging fairness among insurers and maintaining the principle of indemnity.

In the context of insurance, proportionality is vital for managing risks and costs effectively. The Pro-Rata liability provision allows for equitable sharing of the claim among insurers, which is essential for maintaining the integrity of insurance contracts. This approach ensures that no single insurer is disproportionately burdened by the loss, and it promotes responsible risk management among multiple insurers involved in the same coverage.
