Contractual Liability

Overview

Contractual Liability coverage protects a business when it agrees, through a contract, to assume legal liability that would otherwise belong to another party. This is a standard coverage included in most Commercial General Liability (CGL) policies, and it is essential to the way risk is transferred between businesses through contractual indemnification agreements.

How It Works

In commercial relationships, contracts routinely include hold harmless and indemnification clauses. These clauses shift liability from one party to another. For example, a service agreement might state: "Contractor shall indemnify and hold harmless the Property Owner from any and all claims arising from Contractor's operations."

Without contractual liability coverage, the contractor's CGL policy would not cover this assumed liability. The contractor would be personally responsible for fulfilling the indemnification obligation, which could exceed the contractor's financial capacity.

With contractual liability coverage (which is standard in the ISO CGL form), the contractor's insurer steps in and covers the liability the contractor assumed by contract — up to the policy limits.

The "Insured Contract" Definition

The standard CGL policy (ISO form CG 00 01) defines an "insured contract" as any contract under which the insured assumes the tort liability of another party. The definition includes several categories by default:

• Leases of premises
• Sidetrack agreements (railroad)
• Easement or license agreements (except for construction or demolition on or near a railroad)
• Obligations required by municipal ordinance (except for work done for the municipality)
• Elevator maintenance agreements
• Any contract pertaining to the insured's business where the insured assumes the tort liability of another party to pay for bodily injury or property damage to a third person

This last category is the broadest and covers most commercial indemnification agreements.

Why It Matters for Compliance

Contractual liability coverage is the mechanism that makes indemnification clauses enforceable from an insurance perspective. If you require a vendor to indemnify you in your contract, you are relying on the vendor's ability to pay. Contractual liability coverage ensures that the vendor's insurer — not just the vendor — stands behind that obligation.

When reviewing a Certificate of Insurance, contractual liability is not shown as a separate line item. It is embedded within the Commercial General Liability coverage. On some ACORD 25 forms, you may see a checkbox or notation for "Contractual" within the General Liability section, indicating that the standard contractual liability coverage has not been excluded.

If contractual liability is excluded from a vendor's CGL policy (which is rare but possible through a specific exclusion endorsement), the vendor's indemnification obligations in your contract are not backed by insurance. This is a significant compliance gap.

Limitations

Contractual liability coverage does not cover every contractual obligation. Key exclusions include:

• Liability assumed in a contract for the insured's own negligence in some jurisdictions
• Liability under workers' compensation obligations
• Liability arising from professional services (covered by Professional Liability, not CGL)
• Punitive damages in many jurisdictions

Example

A property owner's lease requires the tenant to "indemnify, defend, and hold harmless the Landlord from all claims arising from Tenant's use of the premises." A visitor is injured in the tenant's space due to the tenant's negligence and sues both the tenant and the landlord. The tenant's CGL policy, through its contractual liability coverage, covers the tenant's obligation to indemnify the landlord — paying the landlord's defense costs and any settlement or judgment, up to the CGL policy limits.
