Umbrella Insurance

Last reviewed September 15, 2026

Adds a layer of liability above your auto, home, boat and rental policies, paying once their limits are spent. It is priced by the limit you choose and the policies beneath it, and it pays some claims those policies never would.

A personal umbrella is a single liability policy that sits over the liability parts of every other personal policy you hold. When a crash, a dog bite or a drowning at your pool produces a judgment larger than the auto or home limit, the underlying policy pays up to its limit and the umbrella pays the rest, up to its own. It pays the defense too, and on a serious injury claim the lawyers can cost as much as the verdict.

Because the umbrella only pays after the underlying limit is exhausted, the carrier requires those limits to meet a stated floor before it will write the policy, and the floor applies to every car, home, boat and rental unit on the schedule. That is the mechanism to understand: the umbrella is inexpensive relative to its limit precisely because the first layer of every claim is paid by another policy.

The premium follows the limit chosen and what sits underneath: the number of cars and drivers, homes, boats, rental units, whether there is a young driver, a pool or a dog of a breed the carrier scores, and the household's claim record. The analysis looks at net worth and future income, both of which a judgment can reach, and sets the limit from there. For a household with little of either and no drivers, the recommendation can be that an umbrella is not yet worth its premium.

Covered and not covered

Covered

Bodily injury judgments above your auto liability limits
Injuries at your home or pool above the home liability limit
Dog bites and injuries caused by household members away from home
Libel, slander and other personal injury claims a home policy excludes
Defense costs on a covered claim, often outside the limit
Claims arising from a boat, RV or rental property on the schedule

Not covered

Your own injuries or property, unless excess uninsured motorist is added
Business and professional liability, including a side business run from home
Intentional harm and criminal acts
Vehicles, boats or properties you own but did not list
Liability you assumed in a contract
The layer beneath the required underlying limit, if you let an underlying policy lapse

What umbrella insurance does

How the layers stack

Suppose your auto policy carries a bodily injury limit of $250,000 per person and you cause a crash that ends in a $900,000 judgment. The auto carrier pays $250,000 and the defense to that point. A $1 million umbrella pays the remaining $650,000 and the defense from there. Without the umbrella the balance is collected from savings, from home equity above the state's homestead protection and, in the states we serve, from wages for years. The same stacking applies over the home policy for an injury on your property and over a boat or rental policy that is listed on the umbrella's schedule.

Underlying limit requirements

The umbrella lists a required underlying limit for each policy beneath it: auto bodily injury and property damage, home personal liability, watercraft, recreational vehicles and rental properties. If an underlying policy is dropped below that number or lapses, the umbrella still attaches at the required limit, and the gap between what you carry and what the umbrella expected is yours. Some carriers write the umbrella only when the auto and home are with them; others accept outside policies and ask for the declarations pages each year.

What the umbrella covers on its own

Beyond adding a layer, most umbrellas cover claims the underlying policies leave out: personal injury in the legal sense, meaning libel, slander, defamation and false arrest, along with liability from incidents abroad and some claims involving vehicles you rent or borrow. For these the umbrella pays from the first dollar after a self-insured retention, a deductible-like amount that is usually modest. What is covered here varies by carrier more than any other part of the form.

Excess uninsured motorist

Everything above pays other people. Some carriers offer an endorsement that extends uninsured and underinsured motorist coverage to the umbrella limit, so that when an uninsured driver injures you or a family member badly the umbrella pays your side. It is not offered everywhere and it adds to the premium, but for a household whose exposure runs the other way it is often the more valuable half of the policy.

Exclusions

A personal umbrella excludes business and professional liability, including a side business run from the house, intentional harm, liability you took on in a contract, and any vehicle, boat, aircraft or property that is not listed on the schedule. A rental house or a ski boat left off the schedule is uncovered, which is the most common umbrella claim denial.

Auto InsurancePays what you owe other people after a crash, and, if you choose, repairs or replaces your own car. The liability limits you pick decide how much of your own money is exposed; the deductibles decide what a claim costs you on the day.
Home InsuranceRebuilds the house, replaces what is in it and pays what you owe if someone is hurt on your property, less the deductibles on the page. The dwelling limit, the settlement basis on the roof and contents, and the wind and hail deductible decide what a bad year actually costs you.
Boat & Watercraft InsuranceRepairs or replaces the boat, motor and trailer, pays for people you injure on the water, and covers towing, wreck removal and fuel spill cleanup that a home policy never touches. Hull value, horsepower, navigation area and where the boat is stored set the premium.
Landlord / Rental Property InsuranceInsures a house, condo or small building you rent to others: the structure, the rent you lose while it is repaired, and lawsuits from tenants and visitors. Written on a dwelling fire form, because a homeowners policy stops responding once the owner moves out and a tenant moves in.
Commercial Umbrella InsuranceA second layer of liability limit above your general liability, commercial auto and employers liability policies that pays once one of them is exhausted by a claim. Bought in round increments, priced on the exposures underneath it, and often demanded by contracts before work can start.
