A revocable living trust provides financial protection in the event you are no longer able to manage your financial affairs yourself. You can be trustee while you are healthy, but if you have a stroke or become otherwise incapacitated, your successor trustee would manage your assets in the trust.
You may recall that during the final weeks of his life, former President Richard Nixon refused "heroic measures" and received only palliative (comfort-easing) care at his home. Similarly, former First Lady Jacqueline Kennedy Onassis refused life-prolonging medical intervention before her death from non-Hodgkins lymphoma. Former President Nixon and Mrs. Onassis both retained control over their final medical care through use of a living will and a health care power of attorney.
The federal government imposes a substantial tax on gifts of money or property above certain levels. Without such a tax someone with a sizable estate could give away a large portion of their property before death and escape death taxes altogether. For this reason, the gift tax acts more or less as a backstop to the estate tax. And yet, few people actually pay a gift tax during their lifetime. A gift program can substantially reduce overall transfer taxes; however, it requires good planning and a commitment to proceed with the gifts.
