How to Avoid Uncovered Losses From Third Parties

MAY 5, 2026

Organizations rely on increasingly complex networks of suppliers, vendors, contractors, and service providers. These third parties can boost efficiency, scalability, and innovation — but they also introduce material risk. Supply chain disruption, regulatory scrutiny, and contractual risk-transfer failures are now among the most common causes of uncovered or disputed losses.

Recent third-party risk data highlights the impact. In construction and service environments, third‑party bodily injury and property damage claims tied to subcontractors and vendors remain a leading source of large, uncovered losses. Industry analyses show that 67% of general contractors report claims involving subcontractors, with average uninsured or underinsured subcontractor losses approaching $847,000 per claim once legal defense costs and settlements are included.¹

Compliance breakdowns add to the problem: nearly one‑quarter of certificates of insurance (COIs) reviewed contain material errors or missing endorsements. When a claim falls outside a vendor’s actual coverage, those gaps can leave your organization exposed. when claims arise that fall outside a vendor’s actual coverage. This reinforces why verifying and enforcing third‑party insurance requirements remains critical.

Identify Risk Transfer Opportunities

The first step is determining where risk should be transferred to third parties through contract language and insurance requirements.

Consider a company that hires a contractor to perform routine premises maintenance. The contract requires general liability insurance, but it does not include hold-harmless, indemnification, or additional insured status provisions. When a third party is injured and sues the company, the contractor’s insurer denies coverage, leaving the company to absorb a large deductible and potential premium increases.

To avoid this outcome, contracts should clearly require:

• Defense, indemnification, and hold-harmless provisions. Include an enforceable hold-harmless and indemnity clause, and require that this transfer be backed with additional insured status. 
• Additional insured status (primary and noncontributory). This status provides the additional insured with the right to an immediate defense by the named insured's carrier rather than merely being indemnified for defense costs at a later date. It also helps ensure that defense costs will be paid in addition to policy limits. 
• Waivers of subrogation (when appropriate). Courts can sometimes limit subrogation protections even when additional insured status applies. To reduce that risk, ask for a policy endorsement that allows pre-loss waivers of subrogation.
• Clear guidance on when risk transfer applies — and when your own insurance responds. Structure your liability insurance or risk financing program to respond only when the indemnity clause and additional insured status do not apply, or when those limits are exhausted.

Effective risk transfer helps ensure the party best positioned to control the underlying exposure bears the loss. But contract language alone does not guarantee that insurance coverage will respond as intended. Indemnity provisions routinely require one party to assume liability for another — so the outcome depends heavily on how the applicable policies treat that assumed liability.

Because commercial general liability (CGL) insurance is often the primary coverage for that liability, it’s important to understand what the policy does — and does not — cover under its contractual liability provisions. When you draft or agree to indemnity language, confirm the CGL coverage scope and its key limitations.

Optimize Contract Language and Align Insurance Coverage

Organizations often assume excessive liability through unfavorable contract terms, especially in standard lease, vendor, or customer templates. Too often, teams sign without fully evaluating whether insurance coverage supports those obligations.

For example, a lease may require a tenant to indemnify a landlord for broad environmental liabilities far exceeding the tenant’s actual exposure. Risk assessments, benchmarking, and exposure analysis can often support lower, more appropriate limits. That can reduce insurance costs while still maintaining contractual compliance.

Contract language should also clearly define key responsibilities, including data security and cyber liability, breach notification duties, control of defense costs, and insurance requirements tied to actual exposure rather than blanket limits. This matters even more as regulators emphasize supply chain accountability and risk allocation.

Even well‑drafted contracts can fail if insurance policies do not align with the liabilities assumed. Indemnity provisions often extend beyond bodily injury and property damage to include financial loss, design errors, or performance failures — exposures that many general liability policies do not cover.

In these cases, you may need complementary coverage such as errors and omissions (E&O) or cyber liability insurance to avoid uncovered losses and breach‑of‑contract disputes. Notably, third‑party risk assessments frequently identify misalignment between contract terms and insurance coverage — particularly when organizations rely solely on certificates of insurance instead of reviewing the underlying policy language.
