Your Client Just Got Sued: Claim Defense and the Coverage Gap

28.7% of physicians had been sued by 2024 (Insurance Journal). But you don't need a scalpel to feel that sting. If you're a contractor, consultant, or any professional, a single claim can drain your bank account and your sanity. The real danger isn't the lawsuit itself—it's the way your insurance policy handles the defense. Most business owners assume their policy will cover everything. It won't.

The Scene: A Claim Hits Your Business

Imagine you're a small architect. You've got a general liability policy and a professional liability policy. You've never been sued. Then a client claims your design caused a $500,000 construction delay. Your insurer assigns a lawyer. You think, "Great, I'm covered." But here's where the trap springs.

Defense Costs: Inside or Outside Your Limits?

Here's the first fork in the road. For general liability, defense costs are typically paid in addition to the policy limit. That means if you have a $1 million limit and the defense costs $200,000, you still have $1 million left to pay a settlement or judgment (IRMI). For professional liability, defense costs are commonly included within the limit. So if your professional liability limit is $1 million, and the defense eats $300,000, you only have $700,000 left to pay the other side. That's a huge difference. And most small businesses don't realize it until it's too late.

The Claims-Made Trap

Your professional liability policy is probably written on a claims-made basis. That means you're covered only for claims reported during the policy period—and only for incidents that happened on or after your policy's retroactive date (The Hartford). If you switch insurers, your new policy's retroactive date may be later than the old one. Any incident that occurred before that date isn't covered. You might think you're safe, but you're not.

What Your Policy Actually Covers

General liability covers bodily injury and property damage, plus personal and advertising injury. Professional liability covers financial losses from errors and omissions—like the design flaw that cost your client money. But it won't cover a slip-and-fall in your office; that's general liability territory (The Hartford). And neither covers intentional misconduct, fraud, or criminal acts (Cornell Law School Wex). So if a client claims you deliberately misled them, you're on your own.

The Cost of Defense: Real Numbers

Attorney fees alone can run from $3,000 to $150,000, and settlements can reach millions (The Hartford). If you've got a $1 million professional liability limit, a $150,000 defense leaves you $850,000 for the settlement. That's still decent. But what if you've got a $500,000 limit? You're down to $350,000. And if you lose, you might have to pay out of pocket.

The Fix: Stack Your Defense

You need both general liability and professional liability. The Hartford recommends carrying both for full protection. And consider a commercial umbrella. It extends limits across multiple policies—not just one. But here's the catch: you can't get umbrella coverage without an underlying policy. So start with a solid base.

Here's a quick checklist:

• Check your policy: is defense inside or outside the limit?
• Know your retroactive date—write it down.
• Don't rely on a certificate of insurance. It's just proof of coverage, not a guarantee of what's covered (The Hartford).

Quick tip: If you're a professional, ask your broker to quote the same limits with defense costs outside the limit. It'll cost more, but it could save you.

Bottom Line

The single best move: read your professional liability policy and ask, "Are defense costs inside or outside my limits?" If they're inside, buy a higher limit—or get a policy that pays defense in addition. Don't let a lawsuit eat your coverage before you get to the settlement table.
