How do multiple insurance policies interact?

When more than one policy could respond to the same loss, the interaction between them becomes its own source of risk.

Primary and excess layers, overlapping liability covers, contractual indemnities and other-insurance clauses can combine in ways that leave the insured either double-covered and over-paying, or caught in a dispute about which insurer pays first while the loss sits unfunded.

For a board operating layered or multi-line programmes, the danger is assuming the policies dovetail when, in practice, their wordings may conflict.

This report explains how multiple policies interact in your chosen jurisdiction and industry, and the contribution, subrogation and other-insurance principles that allocate liability between insurers.

It covers the indicators that a programme contains gaps or overlaps at its seams, the impact when insurers dispute priority, and when to engage brokers and coverage counsel to align wordings and resolve inter-insurer questions before they delay a recovery the organisation urgently needs.
