An umbrella policy pays liability claims after your homeowners, auto or other underlying policies reach their limits, and can cover some claims those policies do not, such as libel or slander. New York’s regulator describes umbrella limits as typically $1 million or more, and insurers usually require minimum liability limits on the underlying policies. Households with more assets, more properties, more drivers or more exposures generally have more at stake in a single judgment. Sizing comes down to adding up what you would want protected and the ways a serious claim could arise.
How an umbrella policy works
The Insurance Information Institute describes umbrella insurance as excess liability coverage that adds a layer above homeowners, auto and other vehicle policies, starting when their liability limits are used up. It may also cover risks those policies often don’t, such as libel or slander.
New York’s Department of Financial Services adds that umbrella policies usually cover additional offenses such as false arrest and invasion of privacy, typically with limits of $1 million or more. It also describes a narrower personal excess policy that follows the homeowners policy at a higher limit.
More on the structure is on the umbrella insurance and personal liability insurance pages.
What drives the number
- What you own. New York’s regulator frames the umbrella decision around having sufficient assets you would like to protect.
- Pools, entertaining and dogs. The Insurance Information Institute lists a swimming pool with pool parties and having a dog as reasons to consider more coverage.
- Drivers in the household, especially a teenage driver, which the Insurance Information Institute also names.
- Rental property you own, another exposure the Insurance Information Institute calls out.
- Boats. The standard homeowners form covers watercraft liability only for certain smaller boats.
- Business activity. The standard homeowners form excludes liability from business activities, so a home office, staff or a side business deserves a direct question.
- Several homes, each with its own guests, workers and premises exposure.
Underlying limits have to line up
An umbrella starts where your other policies stop, so insurers set minimums underneath it. The Insurance Information Institute says most insurers want at least $250,000 of liability on the auto policy and $300,000 on the homeowners policy before selling a $1 million umbrella. New York’s regulator notes that insurers may require you to buy and keep certain minimum underlying limits.
Ask what happens under your umbrella if an underlying policy lapses or carries a lower limit than required, and make sure every home, vehicle and boat is listed and checked.
How to think about the limit
Start with a list rather than a number: the homes, accounts and other assets that a judgment could reach, and the exposures above. Then look at how the umbrella limit plus the underlying limits compare to that list.
Households with significant assets, several properties and several drivers usually find the comparison points to a higher limit than a single-home household would choose. The cleanest results come from shopping the home, autos and umbrella together so the layers fit.
If a home is titled to a trust or LLC, confirm the umbrella reflects that. See insuring a home owned by a trust or LLC.
When to revisit it
- A new home, rental property or boat.
- A new driver in the household.
- A pool, trampoline or dog added at any property.
- A change in how a home is titled.
- A significant change in assets.
Common questions
What does an umbrella policy cover that my homeowners policy doesn’t?
It adds liability limits above the underlying policies and may cover some claims they often don’t, such as libel or slander. New York’s regulator also lists false arrest and invasion of privacy as offenses umbrellas usually cover.
Is there a rule for how much umbrella coverage to buy?
No single rule. The decision turns on the assets you want to protect and your household’s exposures, layered on top of your underlying limits.
Do I need certain limits on my home and auto policies first?
Usually. The Insurance Information Institute says most insurers want at least $250,000 of auto liability and $300,000 of homeowners liability before selling a $1 million umbrella.
Does an umbrella cover my boat?
That depends on the umbrella and the underlying boat coverage. The standard homeowners form covers watercraft liability only for certain smaller boats, so boats should be reviewed as their own exposure.
What is the difference between personal excess and umbrella coverage?
New York’s regulator describes personal excess as coverage similar to the homeowners policy at a higher limit, while an umbrella sits over home and auto policies and usually covers additional offenses.
