Insurance, explained

Coinsurance clause: multiple insurers

Coinsurance can describe an arrangement in which two or more insurers directly insure agreed proportions of the same risk. The placement documents identify each participant and its share of the cover.

01 / The meaning

What it means.

A large property placement may be divided between insurers because the required capacity exceeds one insurer’s appetite. A lead insurer may negotiate terms or coordinate aspects of administration, but its precise authority comes from the documents. Each participant’s obligation should be checked: one insurer’s involvement does not by itself mean it guarantees every other participant’s portion.

This meaning differs from a property coinsurance or average clause, which can reduce a claim when insured values are inadequate. It also differs from reinsurance, where an insurer purchases protection for its own exposures. For a shared placement, a business should keep the complete security schedule, endorsements and claims instructions together. Differences between participating terms, currencies or insured entities can complicate an otherwise simple description of percentage shares.

02 / Put it in context

A practical example.

Hypothetical example

Hypothetical example: Two insurers take 60% and 40% of a warehouse risk. A covered loss would be assessed under the agreed placement, including the excess and participants’ obligations; the percentages alone do not establish the final payment.

This example illustrates the term. It does not predict a claim outcome.

A question for your broker.

Who is responsible for each share and for coordinating a claim?
