When a fire ruins your oven, the insurance check comes to you. When a leak from your kitchen ruins the bookshop next door, the check goes to the bookshop, and your insurer also pays the lawyer who answers the bookshop’s claim. The first is first-party coverage, which pays for losses your own business suffers, and the second is third-party coverage, which pays for claims other people make against you.
Every policy you buy sits on one side of that line or, in a couple of cases, straddles it. Knowing which side a policy sits on tells you who gets paid, and above all how to set its limit.
Key takeaways
- First-party coverage pays your business directly for its own losses, usually without anyone having to prove fault.
- Third-party coverage, also called liability coverage, defends your business and pays people who claim you harmed them, up to your limits.
- One incident can set off both kinds at once, such as a leak that ruins your stock and the shop next door.
- Cyber insurance commonly includes both halves: your own recovery costs and claims from people whose data was exposed.
- Some of the costliest losses fall on neither side, so check the gaps before you need them.
Who the parties are
You, the business that buys the policy, are the first party, the insurer is the second, and anyone else, from a customer to a stranger walking past your door, is a third party. That’s all the jargon there is, and the California Department of Insurance uses the same split when it sorts commercial insurance into property insurance for your own property that’s stolen, damaged or destroyed, and casualty insurance for liability when your negligence injures a third party or damages their property.
With first-party coverage, you make the claim yourself, an adjuster checks that the loss came from something the policy covers, and the payment comes to your business minus your deductible, usually with no question of blame at all, so if lightning starts a fire in your salon, nobody has to have been careless for the claim to work.
Third-party claims run the other way. Someone else files, your insurer investigates and defends you, and if you’re legally responsible, it pays them. You never see that money, but what you get is a defense and, up to your limits, a business bank account that stays intact.
Which side is each of your policies on?
Six of the eight sort cleanly. Two don’t.
| Policy | First or third party | Who it protects | A typical claim |
|---|---|---|---|
| General liability | Third party | People your business injures or whose property it damages | A customer slips by your register |
| Professional liability | Third party | Clients who say your work cost them money | A missed deadline costs a client a launch |
| Commercial property | First party | Your equipment, furniture, stock and improvements | A break-in clears out a rack of stock |
| Business income | First party | Your income and ongoing expenses while you’re closed | A fire closes your kitchen for two months |
| Tools and equipment | First party | Your tools on job sites, in transit and in storage | Saws are stolen from your truck |
| Cyber | Both | Your systems and data, and people whose data you hold | Ransomware locks your files, then customers bring claims |
| Workers’ comp | Mostly its own category | Your employees, under your state’s rules | A line cook burns a hand |
| Garagekeepers | Depends on the option | Customers’ cars in your care | A car slips off your lift (either form); hail on the lot (direct coverage only) |
Workers’ comp pays medical care and lost wages to your injured employee under your state’s rules, generally without anyone proving fault, which makes it feel first-party even though the person being paid isn’t you. The employer’s liability part that usually comes with it is plainly third-party, because it covers lawsuits from employees or their families over a work injury.
Garagekeepers depends on the form you choose, because legal liability coverage pays only when your shop is legally responsible for damage to a customer’s car, so it behaves like any other liability policy, while direct coverage pays for covered damage regardless of fault and works much more like first-party coverage for property you don’t own. Garagekeepers vs. garage liability explains how to choose.
Compare cyber quotes on the shared limit
Cyber sits on both sides at once, which is why its quotes are harder to compare than most. The Federal Trade Commission’s cyber insurance guide, which credits the National Association of Insurance Commissioners with helping develop it, lists first-party cyber costs such as legal counsel to work out your notification duties, recovering lost data, notifying customers, lost income from business interruption, cyber extortion and fraud, and forensic investigation. Its third-party list covers payments to consumers affected by a breach, claims and settlements, and the cost of litigation and responding to regulators.
In practice, one policy can be paying your forensic team in the same month it’s defending you against the customers whose records leaked. So before you compare prices, find out whether both halves draw on one shared limit or have their own, because a single large breach can use up a shared limit on the first-party side before the lawsuits even arrive, and a cheaper quote with a shared limit may be the weaker policy.
One burst pipe, both kinds of claim
This is why owners get surprised in both directions: general liability won’t pay for your own damage, however clear the cause, and property insurance won’t pay the neighbor, however sorry you are.
The losses that land on neither side
The more useful lesson sits between the two sides. Owners tend to assume that if a loss is either “mine” or “someone else’s,” one of their policies must cover it, but several of the most expensive small-business losses fall into the space between the two kinds of coverage, and they’re excluded on purpose.
Your own employees’ injuries: general liability protects third parties, and for this purpose your employees don’t count as third parties. Their work injuries go to workers’ comp, and a business without it can find that its liability policy won’t touch an employee’s claim at all. Workers’ comp vs. general liability walks through who pays when someone gets hurt.
Other people’s property in your hands: a customer’s car in your bay or a client’s laptop you’re repairing isn’t yours, so your property policy may not cover it, and liability policies commonly exclude property in your care, custody or control. It’s someone else’s property, but it’s in your possession, and that combination falls between the policies unless you buy coverage written for it, which is the whole reason garagekeepers exists.
Redoing your own faulty work: if a contractor’s bad pipe joint floods a client’s basement, general liability may respond to the water damage, subject to its terms. The cost of tearing out and redoing the joint itself is usually treated as a business cost, on the reasoning that insurance is meant for accidents, while the quality of your workmanship is your own risk.
Money you were tricked into sending: an email scam that diverts a payment is your own loss, but it isn’t physical damage, so property insurance usually won’t pay, and nobody is suing you, so liability doesn’t apply either, though some cyber policies offer limited coverage for it, and some businesses buy a separate crime policy for it, which Corgi doesn’t sell. Email scams and wire fraud explains where that coverage may come from and how small the limit can be.
None of these gaps is exotic, though, since each one comes from an ordinary day at an auto shop, a contractor’s truck, an office inbox or a kitchen, which is why what business insurance doesn’t cover is worth reading before you buy.
Why the split changes how you buy
So why should any of this change what you buy? Mostly because of limits, since a first-party limit should match a number you can measure, such as what it would cost to replace your equipment and stock at today’s prices or how many months of income you’d need to reopen, while a third-party limit is a judgment about how large a claim against you could get, and it’s often set for you by a lease or client contract. How to choose liability limits covers that second kind.
The first kind is easier to get wrong, because it looks like a simple number. An owner who guesses at a property limit and never updates it can find out after a fire that the equipment they bought five years ago costs far more to replace today. Valuation is a first-party question too: whether you’re paid replacement cost or actual cash value only matters for your own property, and it can change a claim by thousands of dollars.
Deductibles differ as well, since a first-party deductible comes off your own payout, while a liability policy may have its own deductible, apply it differently or have none, so check your declarations page for each policy separately.
See what general liability costs for your business
About five minutes, all online. Your certificate is ready the day you buy.
Landlords and clients mostly ask about the third-party side, usually on a certificate of insurance, so it’s easy to buy liability coverage because a contract demands it and leave the first-party side to chance. A lease may require you to insure your own improvements, and a lender may ask about the oven it financed, but nobody checks whether your limit is high enough. That part is on you.
Frequently asked questions
Is liability insurance first-party or third-party coverage?
Liability insurance is third-party coverage. General liability, professional liability and the liability parts of cyber and workers’ comp respond when someone outside your business claims you harmed them, paying for your defense and for damages you’re legally responsible for, up to your limits.
Does first-party coverage depend on who was at fault?
Usually not. First-party coverage like commercial property pays when a covered cause, such as fire, theft or wind, damages your property, whether or not anyone was careless, so what matters is whether the policy’s terms cover the cause.
Does third-party coverage ever pay me?
Not directly. Third-party coverage pays the person making the claim, along with your legal defense, and its value to you is that a covered claim doesn’t come out of your business’s own money, up to your policy limits.
Do I need both kinds of coverage?
Most businesses carry some of each, because most can both suffer a loss and cause one. A café with a lease might carry general liability for customers and property coverage for its equipment, but which policies you need depends on what you own, who you serve and what your contracts require.
Is cyber insurance first-party or third-party?
Commonly both. First-party cyber coverage helps with your own costs, like restoring data and notifying customers, and third-party cyber coverage helps when people whose data was exposed, or regulators, bring claims, so check what each part covers and whether the limits are shared.
