General Liability Insurance Definition & Compliance Guide

General liability insurance - formally known as commercial general liability (CGL) insurance - is the foundational coverage required in virtually every commercial contract. It protects the insured against third-party claims for bodily injury, property damage, and personal and advertising injury arising from their operations, products, or completed work.

When a vendor, contractor, or tenant is required to carry insurance, general liability is always the first line item on the list. Understanding what it covers, what the standard limits mean, and how to read a CGL section on a certificate of insurance is essential to any compliance program.

What General Liability Insurance Covers

A standard CGL policy covers three broad categories of claims:

Bodily injury and property damage. Claims from third parties (not employees) who suffer physical harm or property damage due to the insured's operations. A customer who slips on a wet floor at a vendor's location, or a contractor's crew that damages a client's property - these are the protections CGL is built for.

Personal and advertising injury. Claims arising from libel, slander, false arrest, malicious prosecution, copyright infringement in advertising, or similar non-physical harms. This coverage is often overlooked but is included in standard CGL policies.

Medical payments. No-fault payments for minor medical expenses incurred by a third party at the insured's premises or due to the insured's operations, regardless of legal liability. This is a goodwill coverage designed to resolve small claims quickly.

What General Liability Insurance Does Not Cover

Standard CGL policies exclude:

• Professional errors and omissions - advice, design, or professional services failures are excluded; these require professional liability insurance
• Employee injuries - covered by workers' compensation, not CGL
• Auto liability - covered by commercial auto insurance
• Intentional acts - deliberate harm is not covered
• Pollution - typically excluded or limited; separate pollution liability is often required
• Cyber incidents - typically excluded; requires cyber liability coverage

Understanding these exclusions matters when drafting or reviewing insurance requirements. If your vendor's work includes professional advice, design work, or environmental exposure, CGL alone is not sufficient.

Standard Limits in Contract Requirements

CGL limits appear in two forms on a COI:

• Per occurrence limit - the maximum the insurer will pay for any single claim or occurrence
• General aggregate limit - the maximum the insurer will pay for all claims during the policy period

Common contractual requirements include:

• $1,000,000 per occurrence / $2,000,000 aggregate - standard for most commercial contracts
• $2,000,000 per occurrence / $4,000,000 aggregate - common in construction and higher-risk contracts
• Higher limits supplemented by umbrella or excess liability

The per occurrence vs. aggregate distinction is important: a policy with adequate aggregate limits can still fail to satisfy a per-occurrence requirement if the per-occurrence limit is lower than specified.

Reading the General Liability Section of a COI

On an ACORD 25 form, the CGL section appears in the commercial general liability row. Key fields to verify:

1. Policy number and carrier - confirms a specific policy is in force with an identified insurer
2. Effective and expiration dates - must cover the period of performance or tenancy
3. Each occurrence limit - must meet or exceed the per-occurrence requirement in your contract
4. General aggregate limit - must meet or exceed the aggregate requirement
5. Products/completed operations aggregate - a separate aggregate that applies to completed operations claims; contracts may require this separately
6. Additional insured status - must be noted for the correct entity if required by your contract
7. Waiver of subrogation - must be noted if required

Common Compliance Issues

Aggregate limits partially consumed. The COI shows a $2 million aggregate, but if the policy is mid-term and prior claims have consumed $1.5 million of that aggregate, only $500,000 remains available. COIs do not show remaining aggregate limits.

Products/completed operations aggregate excluded. Some contracts require products/completed operations coverage to be maintained for a period after project completion. If this aggregate is not present or is too low, the requirement is unmet.

Wrong entity as additional insured. The most common issue: additional insured noted on the CGL line but for the wrong entity name, or with a scope that does not include completed operations when the contract requires it.

Occurrence vs. claims-made form. Most CGL policies are occurrence-based, but some are claims-made. Contracts often specify occurrence form. If a claims-made policy is submitted, it does not satisfy an occurrence requirement.

How Bramble Helps

Bramble reads your contracts to extract CGL requirements - limits, endorsements, form type, and scope - then compares them against submitted COIs line by line. Limit shortfalls, missing endorsements, and form type mismatches are flagged automatically.
