Coverage guide

Personal liability

Liability cover is the part of a homeowners policy that has nothing to do with your house. It exists for the day someone says you are responsible for harming them, and it is the coverage most likely to matter more than everything else combined.

What it actually does

Personal liability responds when you are legally responsible for bodily injury or property damage to another person. It does two separate things, and the second is easy to overlook.

It pays damages up to the policy limit. It also provides a defence — the insurer appoints and pays lawyers to defend the claim, and in most policies those defence costs are paid in addition to the limit rather than out of it. For the large majority of claims that never reach a judgment, the defence is the coverage that is actually used.

Cover follows the insured rather than the address. A household member causing injury away from home — on holiday, at a rented property, on someone else's premises — is generally within scope, subject to the exclusions.

Medical payments, which is not the same thing

Alongside liability sits a small medical payments limit that pays a guest's reasonable medical costs without any finding of fault. It is deliberately modest and it is deliberately no-fault; its function is to settle a minor incident quickly and neighbourly before it becomes a claim about blame.

The standard exclusions

Personal liability is broad but not unlimited. Cover generally does not extend to:

• Intentional acts — harm you meant to cause.
• Business activities, including a home business or a side trade run from the property.
• Motor vehicles, which are covered by the auto policy instead; watercraft and aircraft have their own rules and limits.
• Injury to household members, and to the named insured.
• Contractual liability you have taken on by agreement.
• Professional services you provide.

Two of those deserve emphasis locally. A business run from home — equipment repair, produce sales, any trade with customers coming to the property — sits outside the personal policy and needs its own arrangement. And a swimming pool, a trampoline or a dog can each attract specific conditions, surcharges or exclusions; some breeds are excluded outright by some insurers. None of that is hidden, but it is only found by reading.

How much is enough

Base policy limits are commonly set at a level that has not kept pace with what a serious injury claim now costs. The relevant question is not what feels adequate but what you have to lose: home equity, savings, investments, and in California a share of future wages that a judgment can reach.

Raising the underlying limit is usually inexpensive. It is one of the few places in a policy where a meaningful increase in protection costs very little.

Where the household boundary sits

Liability follows the people the policy names and the relatives who live with them, which is a wider group than owners often assume and occasionally a narrower one. A student living away at college is usually still within the household; an adult child who has moved out and established their own residence usually is not, even if the room is kept. A live-in carer, a lodger or an exchange student may fall outside entirely.

None of that is obscure, but it is decided by the policy's own definitions rather than by how the family thinks of itself. If anyone is living in the house whose status is ambiguous, that is a question to settle in advance rather than in the middle of a claim.

Where an umbrella sits

A personal umbrella policy adds a further layer above both the homeowners liability limit and the auto liability limit, typically starting at a million dollars. It also tends to be broader than the policies beneath it in specific respects.

Umbrellas require the underlying policies to carry stated minimum limits. If those underlying limits drop below the requirement, the umbrella may not respond as expected — so the layers have to be reviewed together rather than separately.

The California Department of Insurance's residential insurance guide sets out where liability sits within a homeowners or renters policy.
