Cross-Liability Exclusion
Also known as: insured versus insured exclusion, insured-vs-insured provision
A cross-liability exclusion (sometimes phrased as an insured-versus-insured provision) governs what happens when one party covered by a policy brings a claim against another party covered by that same policy. A strict cross-liability exclusion bars coverage for these intramural suits, on the theory that a policy should not fund a fight between two of its own insureds. The concept is especially important on policies with multiple named insureds, joint ventures, and additional insureds, where one insured's negligence might injure another. It is the mirror image of, and interacts directly with, severability of interests.
For a small-business buyer, the practical question is whether your policy will defend you if a co-insured points the finger at you. Many general liability forms actually permit claims between insureds because the separation-of-insureds condition treats each insured as if it had its own policy — so an employee of one insured injured by another insured may still recover. However, directors and officers policies frequently retain a firm insured-versus-insured exclusion to stop collusive lawsuits among executives. Knowing which stance your policy takes tells you whether internal disputes are covered or a costly gap.
A key nuance: the presence or absence of a cross-liability exclusion changes the value of naming multiple parties on one policy. If you add a client or partner as an additional insured on a policy that bars insured-versus-insured claims, you may unintentionally block your own ability to recover from that co-insured after a loss. This overlaps with the anti-subrogation rule, which independently stops an insurer from suing its own insured. Before agreeing to broad additional-insured requirements, confirm how cross-liability and severability language interact so you preserve, not surrender, your recovery rights.
Because ISO's standard Commercial General Liability form (CG 00 01) already covers each insured separately through its Separation of Insureds condition, a cross-liability exclusion is what carriers add to bar one insured from suing another under the same policy.
Real-world scenario
Consider Harbor Point Hospitality LLC, which operates a 90-seat restaurant, and its sister entity Harbor Point Realty LLC, which owns the building. To save money, the owner listed both companies as named insureds on a single commercial general liability policy carrying a $1,000,000 per-occurrence limit, a $2,000,000 general aggregate, and a $1,000 deductible, for an annual premium of $6,800. A dishwasher employed by the Hospitality entity slipped on a poorly maintained loading-dock ramp owned by the Realty entity and suffered a shoulder injury. Workers' comp paid $48,000 in medical and wage benefits, but the worker also sued Harbor Point Realty LLC in tort for $750,000, alleging the landlord entity negligently maintained the ramp.
Because Realty is a separate named insured being sued by the injured party, this looks like a covered third-party claim. But the owner's older ISO form contained a cross-liability exclusion barring coverage for suits by one insured against another. The carrier denied defense, and Harbor Point paid $22,000 in early defense costs out of pocket before a coverage attorney intervened. Had the policy instead included a severability of interests condition and no cross-liability bar, the insurer would have owed defense and any settlement up to the $1,000,000 limit.
After the scare, the owner restructured: separate general liability policies for each LLC at $4,200 and $3,100 respectively, plus a $1,500 charge to add each entity as an additional insured on the other. The claim ultimately settled for $310,000, with $68,000 in legal fees — a $400,000 total lesson in how one clause can erase six figures of expected protection.
How it affects your premium
A cross-liability exclusion is a policy provision, not a separately rated coverage, so it rarely carries its own line-item charge. Instead, whether you can negotiate it away — and what that costs — depends on these underwriting factors:
- Number of named insureds on one policy. The more affiliated entities (holding companies, real-estate LLCs, operating companies) share a single policy, the more likely an underwriter insists on the exclusion to limit intra-family suits.
- Presence of a severability of interests clause. Policies built on a modern severability of interests condition treat each insured separately, which can offset a broad cross-liability bar; older or manuscript forms may not.
- Common ownership and employee sharing. When one entity's employees work on another entity's premises, insurers see higher intra-insured injury exposure and price or exclude accordingly.
- Industry and injury frequency. Construction, hospitality, and habitational risks with frequent premises and operations claims draw tighter cross-liability language.
- Requested endorsements. Buying an endorsement to delete or narrow the exclusion may add a modest premium or trigger higher minimums.
- Use of additional-insured status instead. Structuring cross-coverage through additional insured grants rather than shared named-insured status changes both price and how the exclusion applies.
- Claims history between affiliates. Any prior suit by one insured against another is a red flag that hardens terms at renewal.
Common misconceptions
Myth: If both my companies are named insureds on the same policy, we're both fully protected if one sues the other.
Reality: A cross-liability exclusion can bar exactly that claim — coverage for suits by one insured against another. Without a severability of interests condition or a deletion endorsement, the policy may treat the whole thing as an uninsured internal dispute.
Myth: A cross-liability exclusion is the same thing as the standard employee-injury or your-work exclusion.
Reality: It is a distinct exclusion aimed specifically at claims between insureds on the same policy, not at the general employer's-liability or work-product bars. A claim can pass those tests and still be denied under cross-liability.
Myth: Adding a second entity as an additional insured is riskier than naming it, so I should just list both as named insureds.
Reality: Often the opposite is true. Additional insured status can preserve the intent to cover suits between the parties while avoiding the broad cross-liability trap that shared named insured status can trigger.
