Which insurance principle is preserved with the use of the pair and set clause?

Subrogation is the right of an insurer to pursue a third party that caused a loss to the insured, recovering amounts paid in claims. While important, this principle relates to the insurer's ability to reclaim losses rather than the preservation of the insured's financial position, which is the focus of the pair and set clause.

Utmost good faith, or "uberrima fides," requires both parties in an insurance contract to act honestly and disclose all relevant facts. While this principle is essential for the contract's validity, it does not directly relate to the pair and set clause's role in ensuring that the insured does not profit from their claim.

Insurable interest is the requirement that the insured must have a legitimate interest in the subject matter of the insurance. Although critical for the validity of an insurance contract, the pair and set clause specifically addresses the indemnity aspect, making it distinct from the concept of insurable interest.
