Business Liability Insurance

Business liability insurance is the coverage a business buys against claims by third parties, and the form the phrase almost always refers to in practice is the commercial general liability policy. It insures damages the business becomes legally obligated to pay because of bodily injury or property damage arising out of its operations, premises, or completed work, together with a defined set of personal and advertising injury offenses. It is the coverage a client's contract or a commercial landlord's lease names by name, and the one a client is asking to be added to when they request additional insured status.

The name is broader than the policy. In ordinary speech "business liability insurance" sweeps in professional liability, employment claims, vehicle liability, and cyber coverage, each of which is a separate policy answering a separate loss. This entry covers the general liability form and points to the others, because buying one of them in the belief that it does the work of several is the most expensive misunderstanding in small-business insurance.

The three coverage parts are not variations on one idea, and knowing which one a claim would fall under is how you tell whether you are covered at all.

Coverage A responds to bodily injury and property damage, which is the customer who trips on the entryway and the contractor whose ladder goes through a window. Coverage B responds to personal and advertising injury, and the standard form defines that as a specific list of offenses, among them libel, slander, invasion of privacy, wrongful eviction, and infringement of copyright in an advertisement. That closed structure is the part worth holding on to. A reputational or intangible harm is covered if it matches a named offense and not merely because it feels like a personal injury. Coverage C pays medical expenses for someone injured on the premises without regard to fault and without waiting for a lawsuit, in small amounts, which is why a minor incident can be closed quickly and quietly.

What the form does not reach is where most owners guess wrong, and the reason matters more than the answer. A claim that your work was defective, that your advice was wrong, or that a deadline you missed cost a client money is a claim for pure economic loss. Nobody was physically hurt and no property was damaged, so the claim never satisfies the grant in the first place and never gets as far as the exclusions. The base standard form does not contain a blanket professional-services exclusion, which is often added by endorsement where the insurer wants one. So the common explanation, that professional services are excluded, is both weaker and partly wrong: a business that goes looking for the exclusion to negotiate is solving the wrong problem, and what it actually needs is a second policy written to cover professional acts.

Whether the policy is written on an occurrence form or a claims-made form is the decision with the longest tail. An occurrence form responds to injury that happens during the policy period no matter how late the claim arrives, so coverage for a given year keeps working after that year ends. A claims-made form responds only to claims made during the period, subject to a retroactive date, so letting the policy lapse or switching insurers can strand years of past exposure unless tail or prior-acts coverage is bought. General liability is conventionally written on an occurrence form and professional liability conventionally claims-made, which is a second reason the two cannot be compared as though they were the same product with different names.

Two more wording questions decide what a limit is actually worth. The first is whether defense costs are paid in addition to the limit or come out of it. General liability conventionally pays defense on top of the limit, while many professional and management-liability forms pay defense within it, and because defense can exceed the damages in a claim that is eventually dismissed, two quotes at the same limit can be different products. That is a convention rather than a rule, so it is worth confirming on the form rather than assumed. The second is the difference between an additional insured and a certificate holder. Adding a client or landlord as an additional insured extends your policy's coverage to them by endorsement, which genuinely changes the risk your insurer is carrying. A certificate of insurance is evidence that a policy exists and confers nothing at all. Contracts ask for one and mean the other often enough that reading which was requested is part of reviewing the contract.

One boundary is worth stating plainly because it is a recurring assumption. Forming a limited liability company is not a substitute for insurance. An entity can limit an owner's personal exposure to certain claims, but it does not stop a claim from reaching the business's own assets, and it does not pay to defend one. Insurance, for its part, does not create an entity. A business needs an answer to both questions.

A claim runs through the policy in a fixed order. Something happens. The insurer asks whether the resulting damages are because of bodily injury or property damage, or whether they match one of the named personal and advertising injury offenses. If neither, the claim is outside the grant and the analysis stops. If it is inside the grant, the exclusions are read next, then the limits are applied, and the duty to defend is triggered, which is often worth more than the indemnity because the insurer takes over the lawyers.

The limits are where a policy quietly runs out. A per-occurrence limit caps what the insurer pays for any one claim. A general aggregate caps what it pays across the whole policy year, and it does not reset when a claim is closed. There is typically a separate products-completed-operations aggregate for claims arising out of finished work, plus small sub-limits for damage to premises rented to you and for the Coverage C medical payments.

A hypothetical example of the aggregate binding, with invented figures. Rowan's landscaping business carries a $1,000,000 per-occurrence limit and a $2,000,000 general aggregate. Early in the year a retaining wall fails and the claim settles at $700,000. In the summer a crew damages a neighbor's irrigation and outbuilding, settling at $800,000. The insurer has now paid $1,500,000, so $500,000 of the aggregate remains. In November a client's guest is injured on newly laid steps and that claim settles at $900,000, comfortably inside the per-occurrence limit. The aggregate is the binding constraint, so the policy pays $500,000 and the remaining $400,000 falls on the business. Nothing about the third claim was unusual; the year was.

Pros

• Covers the losses a homeowners or renters policy expressly will not, since personal policies generally exclude business liability and cap business property in the home at a token sublimit.
• Includes the insurer's duty to defend, which can be the larger benefit, since defense costs arrive whether or not the claim has merit.
• Conventionally written on an occurrence form, so a policy year keeps responding to injuries that happened in it long after it ends.
• Satisfies the contract and lease requirements that name it directly, and supports the additional insured endorsements clients ask for.
• Coverage C settles small on-premises injuries without fault or a lawsuit, which can stop a minor incident becoming a claim.

Cons

• Does not cover a claim that your professional work or advice caused financial harm, and that gap is in the grant rather than in an exclusion a reader could go looking for.
• The aggregate caps the policy year, so a bad run can leave a later claim partly uninsured even when each claim sits inside the per-occurrence limit.
• Whether defense costs sit inside or outside the limit varies by form, so two policies quoted at the same limit are not necessarily comparable.
• Covers neither employee injuries nor employment claims nor company vehicles, each of which is a separate policy.
• Adding a client as an additional insured extends your coverage to them, which is a real cost of a request that looks administrative.
