Our policy protects "you" and "you" are defined as:
"yourself, your spouse and any members of your immediate family who normally reside with you AND are financially dependent on you."
Sorry, but your friend should rather get their own Pineapple policy
You can, however, insure your kids' stuff, that of your spouse or members of your immediate family.
Why?
If someone is not part of your immediate family, does not live with you, or is not financially dependent, there is no insurable interest. Instead, they represent a completely different risk profile, which we use to calculate their risk and give them a fair premium.
