Contractual Liability
Also known as: Assumed Liability, Contractually Assumed Liability
Contractual liability is liability a business assumes by agreement instead of having it imposed directly by tort law. Every time you sign a lease, subcontract, vendor agreement, or venue rental that contains an indemnity or hold harmless agreement, you are taking on contractual liability — you are promising to answer for losses that the law might otherwise assign to the other party. The standard CGL policy addresses this with an exclusion for assumed liability, then restores coverage for the specific promises that fit its insured contract definition.
For a small-business owner, understanding contractual liability is essential because it is one of the few ways you can dramatically expand your own exposure with the stroke of a pen. Agreeing to a broad-form indemnity can make you responsible for another party's negligence, and if that assumed liability falls outside the insured-contract carve-back, you could be paying claims your policy will not cover. The safest posture is to confirm that every indemnity you sign is matched by coverage and, where the contract requires it, by additional insured status.
The practical nuance is the split between the parties: the one giving protection is the indemnitor and the one receiving it is the indemnitee. Insurers price contractual liability into the CGL premium because it is a routine part of doing business, but they still exclude assumed liability for professional services, product warranties, and pure breach-of-contract damages. Before signing, have a broker map the contract's indemnity language to your policy so the liability you assume by indemnity is one your insurer will actually stand behind.
