Definition:Cross liability clause
📋 Cross liability clause is a provision commonly found in general liability and commercial combined policies that treats each named insured under the same policy as though a separate policy had been issued to each of them. When multiple parties are listed as named insureds — for example, a parent company and its subsidiaries, or joint venture partners — this clause ensures that a liability claim brought by one insured against another is not excluded simply because both share the same policy. The clause is sometimes referred to as a "severability of interests" or "separation of insureds" provision, and its presence or absence can have significant consequences in multi-party commercial relationships.
⚙️ In practice, the clause operates by directing the insurer to apply the policy's terms independently to each named insured as if no other insured existed on the schedule. If Insured A sues Insured B for bodily injury or property damage arising from the insured operations, the policy responds to Insured B's liability in the same way it would if A held a completely separate policy. Critically, however, most cross liability clauses specify that the overall policy limit is not increased by the clause — it remains a shared ceiling across all insureds. This distinction matters in large-scale construction projects, joint ventures, and multinational programs where several entities operate under a single liability placement and each expects to be protected against claims from the others.
💡 Without a cross liability clause, an insured that is sued by a co-insured on the same policy may find that the insurer treats the claim as an internal dispute between parties to the contract rather than a covered third-party claim — leaving the defendant insured unprotected precisely when coverage is most needed. Brokers negotiating policies for joint ventures, consortium arrangements, or corporate groups routinely insist on the inclusion of this clause as standard practice. Underwriters, for their part, must factor in the additional exposure created by the clause when assessing the overall risk — particularly where the named insureds have significant operational interdependencies that increase the probability of inter-party claims. In jurisdictions such as Australia, the clause has been the subject of notable case law clarifying its interaction with subrogation rights and deductible application.
