Personal liability insurance

Household coverage for bicycles, children, pets, water damage, and exclusions.

Direct answers

Personal liability covers legal liability arising from daily life — a child breaking property, a cycling accident, or certain water-leak claims — and one household policy or rider is often enough for the whole family.

Key points

  • One household policy usually covers all family members.
  • It is commonly attached as a cheap rider to auto, fire, or card cover.
  • Business activities, professional liability, and intentional acts are excluded.
  • Confirm the household definition and any liability to household members.

One rider, whole household

Because personal-liability riders are cheap and broad, most families need only one — but confirm the household definition, the limit, whether legal support is included, and that it covers bicycle and pet-related liability.
