Overview
Many commercial general liability policies include a built-in "separation of insureds" clause that functions like a cross-liability provision. That clause treats each insured as if they were the only insured when a claim is made, allowing one insured to pursue a claim against another insured under the same policy without defeating coverage.
This article explains what that clause does, the common limits of its protection, and practical steps to confirm coverage when a contractor or developer asks to be added or reserves the right to sue.
Key takeaways
- Standard liability policies normally include a separation of insureds clause that resembles a cross-liability endorsement.
- Being named on another party's policy is different from being added as an additional insured on your own policy.
- Confirm limits, exclusions, and how excess or umbrella policies respond when multiple insureds are involved.
How it works
When a claim is made against two parties covered by the same liability policy, the separation of insureds language treats each party independently for defense and indemnity purposes. In practice, this means a general contractor can sue a subcontractor covered by the same policy and the insurer evaluates the claim against the defendant as if the plaintiff were not an insured.
The clause does not create a new insured or expand coverage beyond the policy terms; it only prevents the insurer from using co-insured status as a complete bar to coverage. For more detail, see Understanding Cross Liability Endorsements.
What it may cover (and what it may not)
What it may cover: covered bodily injury or property damage claims between insureds, defense costs up to policy limits, and separate limits application when the policy language so provides.
What it may not cover: contractual liabilities that were not assumed on a covered contract, intentional acts, professional errors excluded by the policy, and situations specifically excluded by endorsements. Also remember that excess and umbrella policies may have different terms or follow-form limitations. For examples of how excess coverage interacts with primary policies, see Understanding Excess Liability Policies.
Common mistakes to avoid
- Assuming cross-liability equals being an additional insured — they are different legal and coverage concepts.
- Failing to read endorsements and exclusions that change how limits apply or remove coverage for specific claims.
- Relying on verbal assurances instead of written policy language when a contractor requests to be "added" or to retain the right to sue.
- Overlooking how indemnity agreements and waivers of subrogation can alter who ultimately pays or defends a claim.
Questions to ask an agent
Who is named on my liability policy and how does the separation of insureds clause operate here?
If a general contractor asks to be named or wants to preserve the right to sue, will that change my coverage or limits?
How would a claim between co-insureds affect my policy limits and defense obligations?
Do any endorsements, exclusions, or the excess/umbrella program change how cross-insured claims are handled?
Next steps
Review the liability policy declarations page and any endorsements that modify insured status, limits, or exclusions before agreeing to contract language that affects coverage.
If you have questions about a specific request from a contractor or want to confirm how your policy would respond, talk to an agent.
Frequently Asked Questions
Does a cross-liability clause let one insured recover from another insured under the same policy?
Yes; the separation of insureds language allows one insured to bring a claim against another insured and preserves coverage for the defendant as if the plaintiff were not insured.
Is being covered by the same policy the same as being an additional insured?
No; an additional insured endorsement grants specific coverage rights to another party, while separation of insureds only treats insureds independently for claims handling.
Will a lawsuit between insureds use the same policy limits for both parties?
Often the policy's single limit applies, but policy language and endorsements determine whether limits are shared or applied separately.
Should I accept contractual language that lets a contractor retain the right to sue me?
Review the contract with your agent and insurer first to confirm whether your policy and limits provide the protection you need before agreeing.
