This is the most common way life insurance is purchased.
But, you don’t actually buy the coverage for yourself, you are the insured person, but the coverage provides a death benefit for someone else, for example, your spouse or child.
In order to purchase life insurance on someone you must have an insurable interest in that person.
You always have an insurable interest in yourself, and can therefore buy life insurance on your own life.
