Step 5: Keep Important Records
Store copies of your insurance policies, receipts, photos of valuable belongings, and claim documents in a secure location. Good documentation makes the claims process much easier.
Who Should Pay Extra Attention?
- ✔ First-time insurance buyers
- ✔ Homeowners and renters
