Make a list of your possessions in your household. The more well documented this is the more likely you will be to be able to replace them.
Make sure that you inform your agents of any changes that you make to the home so that if anything happens to the structure, the recent changes will be reflected in the payout.
Check to see if there are any specific limits to what is insured by your company. Sometimes a person may think they are covered for certain things, but the limits negate that.
