People insure valuable items to protect themselves financially in case of loss or damage. There are several types of insurance and rules that policyholders should follow. Key rules include having an insurable interest in the item, providing truthful information, not making a profit from claims, sharing compensation between insurers of the same item, and only receiving a proportional payout if underinsured. To get insured, individuals calculate item values, fill out forms, compare quotes, and select the best coverage for their needs.
