All life insurance is a form of estate planning.

If you’re asking about life insurance used as a funding vehicle to pay for confiscatory estate and inheritance taxes, as well as income taxes with respect to decedent (our estates get to pay income taxes after we die, including untaxed IRA and qualified retirement plans — these taxes can be substantial for almost everyone), then I’ve included some links below to several trade associations of life insurance agents that specialize in using life insurance for estate liquidity:

National Association of Insurance and Financial Advisors
Society of Financial Service Professionals

Oh what a good question.People buy life insurance, usually in trust so it doesn’t also get included in the estate, in order to pay estate taxes. That’s about 97% of what you need to know. Outside of that you just need to look around for the specific information you’re looking for.
