General liability can protect your business when a customer or visitor claims you caused injury or damaged their property. It suits businesses serving customers or working on their premises; your own building, tools and stock need property coverage. [9](https://www.iii.org/article/commercial-general-liability-insurance "Commercial general liability insurance") [10](https://www.insurance.ca.gov/01-consumers/105-type/95-guides/09-comm/commercialguide.cfm "Commercial Insurance Guide") [11](https://www.hiscox.com/documents/partner-agent/specimen_forms/GL_Form.pdf "Commercial General Liability Coverage Form")

## Key Differences in General Liability Insurance

### Coverage Features for the Business

Lockton says it designs custom GL programs through insurers across the global market and groups the line with environmental impairment, medical malpractice, product recall, and umbrella or excess placements. Marsh McLennan Agency describes evaluating GL alongside a company’s operations and liabilities but does not list adjacent casualty lines on its overview.

### Placement and Service Details

Lockton says commercial clients retain the same dedicated service team throughout placement; the Marsh McLennan Agency page invites adviser contact without describing team continuity there.

- Ask Marsh McLennan Agency to identify related policies, attachment points, and the assigned team for this GL placement. [8](https://www.marshmma.com/us/services/business-insurance.html "Business Insurance | MMA")
