Commercial General Liability (CGL) policies are the backbone of business insurance, providing coverage for third-party bodily injury, property damage, and personal injury claims. When an insurer disputes whether CGL coverage applies — asserting an exclusion, challenging the trigger, or denying the duty to defend — the financial exposure can be enormous. Both the insured business and third-party claimants can find themselves in the middle of a coverage dispute that significantly affects their recovery.
The Duty to Defend vs. the Duty to Indemnify
CGL coverage disputes typically involve two distinct obligations: the duty to defend (the insurer must provide and pay for a defense against covered claims) and the duty to indemnify (the insurer must pay any resulting judgment or settlement within policy limits). The duty to defend is broader — it arises whenever there is a mere possibility of coverage based on the allegations — and its wrongful breach by the insurer can be extremely expensive.
When an insurer wrongfully refuses to defend, it may be estopped from later contesting coverage and can be held liable for the full cost of the defense, the underlying judgment (even if it exceeds policy limits), and bad faith damages.
Common CGL Coverage Disputes and Settlement Ranges
Construction Defect Coverage Disputes
Subcontractors and general contractors facing construction defect claims frequently fight with their CGL insurers over whether the "your work" exclusion bars coverage. When insurers wrongfully deny coverage on this basis, settlements resolving the coverage and underlying claim together range from $200,000–$5 million depending on project size. Courts in many states limit the "your work" exclusion narrowly, protecting coverage for consequential damage to third-party property.
Pollution Exclusion Disputes
Broadly worded pollution exclusions are frequently invoked to deny claims involving chemical spills, contaminated stormwater discharge, or indoor air quality claims. Courts are divided on whether the exclusion applies to "ordinary" business activities involving chemicals. Coverage disputes over the pollution exclusion commonly settle for 40–80% of the underlying claim value.
Expected or Intended Exclusion
The "expected or intended" exclusion bars coverage for deliberate acts. Disputes arise when negligent conduct is characterized by the insurer as intentional. Coverage disputes over this exclusion frequently settle for 50–100% of the underlying claim because the line between negligence and intention is genuinely contested.
Additional Insured Disputes
When a contractor's CGL policy is supposed to cover an owner or developer as an additional insured, disputes over the scope of that coverage can result in significant insurer exposure. Successful additional insured claims recover the full cost of defense and any covered portion of the underlying judgment.
Key Factors in CGL Coverage Dispute Value
- Underlying verdict or settlement amount: The coverage dispute is anchored by the value of the underlying claim
- Policy limits: Available limits cap the indemnity obligation, though bad faith for failure to defend can exceed limits
- Number of triggered policy years: Long-term property damage claims may trigger coverage under multiple annual CGL policies
- State coverage law: Courts in different states interpret the same exclusions very differently, making jurisdiction critical

Frequently asked questions
What triggers the duty to defend under a CGL policy?
The duty to defend is triggered when the allegations in the complaint against the insured, if proven true, would potentially be covered by the policy. This "eight corners" test (comparing the complaint and the policy) is applied broadly in most states — even a remote possibility of coverage is sufficient to require the insurer to defend.
What happens if my insurer defends under a "reservation of rights"?
A reservation of rights letter means the insurer will defend you but reserves the right to later deny coverage for any resulting judgment. You generally have the right to retain independent counsel (Cumis or independent counsel) at the insurer's expense when a reservation of rights creates a conflict of interest between the insurer's defense attorney and your interests.
Can one occurrence trigger multiple years of CGL coverage?
Yes — for long-tail claims like environmental contamination or progressive property damage, courts use various trigger theories (injury-in-fact, exposure, manifestation, or continuous trigger) to determine which policy years are triggered. The continuous trigger theory, applied in many states, can trigger all policy years from first exposure to discovery, multiplying available coverage.
What is "stacking" of CGL policies?
When multiple years of CGL coverage are triggered by a single long-tail claim, stacking allows the insured to access the policy limits of each triggered year independently. For a claim spanning 10 years with $1 million annual limits, stacking can produce $10 million in available coverage.
Does the CGL policy cover claims made by my employees?
No — CGL policies specifically exclude claims by employees for employment-related injuries and illnesses, which are covered under workers' compensation and employers' liability insurance. An employment practices liability (EPLI) policy covers discrimination, harassment, and wrongful termination claims by employees.
