Why Your CGL Won't Save You from a $150,000 Attorney Bill

Here's a number that should make you sit up: attorney fees in an errors and omissions (E&O) claim can run from $3,000 to $150,000 (The Hartford, Errors & Omissions). That's just the legal tab—before any settlement or judgment. If you're a small business owner who thinks your commercial general liability (CGL) policy has you covered for every mishap, you're in for a rude awakening. Your CGL is built for bodily injury and property damage—not for the financial losses that come from a botched job or bad advice. This is the coverage gap that has sunk more than one thriving business, and it's time you closed it.

The Scenario: A Graphic Designer's Nightmare

Imagine you run a small graphic design studio. You've got a CGL policy because your landlord and a few clients asked for it. One day, you redesign a client's website, but you accidentally use copyrighted images without a license. The client gets sued for copyright infringement, and they turn around and sue you for negligence and misrepresentation. Your CGL policy? It likely covers personal and advertising injury, which can include copyright infringement, but the catch is that your CGL is designed for physical risks, not the abstract errors in your professional services (The Hartford, Professional Liability). Most CGL policies have a professional liability exclusion. So you're staring at a six-figure legal bill with no coverage.

Why Your CGL Isn't Enough

Here's the blunt truth: general liability and professional liability cover different worlds. General liability covers bodily injury and property damage—like a client slipping on your office floor. Professional liability covers financial losses from errors and omissions in your services (IRMI). And the difference isn't just in what's covered; it's in how the policy works. General liability is occurrence-based, meaning it covers incidents that happen during the policy period, even if the claim comes later. Professional liability is typically claims-made-and-reported, meaning you need a policy in force both when the incident occurred and when the claim is made (IRMI). That's a critical distinction. If you drop your professional liability coverage, you lose the safety net for past work unless you buy an extended reporting period.

The Cost of Closing the Gap

So what does it cost to add professional liability? The Hartford's average minimum monthly premiums for miscellaneous standalone coverage are $62, and for technology-company E&O it's $146 (The Hartford, Professional Liability). For architects and engineers, it's $239 a month. Compare that to the average general liability premium of about $810 a year (The Hartford, General Liability). You're looking at a few hundred dollars a month to protect against a potential $150,000 legal bill. That's a no-brainer. And if you want broader protection, a commercial umbrella policy can extend your limits across multiple policies, but it won't cover professional liability gaps—it only extends underlying policies you already have (The Hartford, Commercial Umbrella). So you can't rely on an umbrella to fix a missing professional liability layer.

What Claims-Made Means for You

Professional liability policies come with a retroactive date and an extended reporting period. The retroactive date means you're only covered for incidents that happen on or after that date (The Hartford, Professional Liability). If you switch carriers, your new policy's retroactive date might be later than when you did the work, leaving you exposed. The extended reporting period—usually 30 to 60 days, but extendable to a year or more for extra cost—gives you time to report claims after the policy ends (The Hartford, Professional Liability). Don't let your policy lapse without considering this. In the design scenario, if you let your E&O lapse and the copyright claim comes in six months later, you're on your own.

The Medical Malpractice Wake-Up Call

If you think professional liability is just for tech and design, look at medicine. Nearly 45.2% of physicians aged 55 and over have been sued, and 59.6% of OB-GYNs have faced a claim (Insurance Journal). Even for younger physicians, the risk is real. And premiums are rising—the share of medical liability premiums that increased year-over-year jumped from 13.7% in 2018 to 39.9% in 2025 (Insurance Journal). This isn't just about doctors; it's a reminder that any professional service can trigger a claim. The lesson: don't wait until you're sued to think about coverage.

Your Takeaway

If you provide any professional service—design, consulting, IT, engineering—you need professional liability insurance, period. Your CGL covers the slip-and-fall, but it won't cover the $150,000 attorney fee from a copyright mistake. The cost is modest—often less than $150 a month for tech E&O (The Hartford, Professional Liability). Get a quote today. And when you review your policy, pay attention to the retroactive date and the extended reporting period. A few hundred dollars a year is a small price for peace of mind.
