In order to buy burial life insurance plans on someone else, you need an Insurable Interest in that person, and you usually need their permission and signature on the application for coverage.
Insurable Interest in someone means you either rely on that person for some form of financial support, or that you would suffer a financial cost (loss) should that person die.
There is usually an insurable interest between spouses, parents and their children, family members, siblings, and business partners.
