The below article is very superficial. For example, although having the trustee originally purchase the insurance is optimal, there are several other ways to transfer the insurance policy into the trust.

ILITs were designed to avoid taxes on life insurance payouts.
ILIT is an acronym for “irrevocable life insurance trusts.
“Why would you need one?
