Insurable interest exists when an individual stands to suffer a financial loss or hardship if another person dies or is injured. Insurable interest is typically present when one is closely related to the person (e.g., spouse, parent, or child) or has a financial relationship with them (e.g., co-signing a mortgage). While maintaining a lasting friendship may suggest emotional interest, it does not typically meet the financial criteria for insurable interest unless there is a direct financial loss involved.
