Finding and removing duplicate insurance

Repeated liability, bicycle, travel, device, employer, and card coverage.

Direct answers

Key points

  • Personal-liability riders are the most commonly duplicated cover.
  • Card and employer benefits often overlap travel and device cover.
  • Duplication rarely pays twice — it usually just wastes premium.
  • Keep one adequate policy per risk and cancel the rest.

Make a one-page inventory

List every policy, rider, card benefit, and employer or cooperative cover against the risk it addresses. Where two cover the same liability, keep the one with the better limit and terms and cancel the duplicate.
