Like you are saying, assets of a business can be transferred into a GRAT
(type of trust). Usually, this is done to transfer ownership without losing half the value of the company to the govt. in taxes upon death. Usually the person passing the assets into the trust has some sort of insurance policy in the event of death before the terms he or she has set up in the GRAT have transpired. I'm not sure exactly how they work, but they involve annuity payments to the grantor, and tax free transfer of the assets at the end of the terms. It's how Walton transferred Walmart to his heirs. I'm not sure how you would do it with a farm, maybe form a corp. and put shares into GRAT, but dying without protecting your business or assets from the thieving government is one of the dumbest things you could do to your kids.
