Irrevocable trusts designed to save on estate tax. There are several kinds; with all of them, you keep income from trust property, or use of that property, for a period of years. When the trust ends, the property goes to the final beneficiaries you've named. These trusts are for people who have enough wealth to feel comfortable giving away a substantial hunk of property. They come in three flavors: Grantor-Retained Annuity Trusts (GRATs), Grantor-Retained Unitrusts (GRUTs) and Grantor-Retained Income Trusts (GRITs).

The failure of a bequest of property in a will. The gift fails (is 'adeemed') because the person who made the will no longer owns the property when he or she dies. Often this happens because the property has been sold, destroyed or given away to someone other than the beneficiary named in the will. A bequest may also be adeemed when the will maker, while still living, gives the property to the intended beneficiary (called 'ademption by satisfaction'). When a bequest is adeemed, the beneficiary named in the will is out of luck; he or she doesn't get cash or a different item of property to replace the one that was described in the will. For example, Mark writes in his will, 'I leave to Rob the family vehicle,' but then trades in his car in for a jet ski. When Mark dies, Rob will receive nothing. Frustrated beneficiaries may challenge an ademption in court, especially if the property was not clearly identified in the first place.

A trust in which the income is retained and not paid out to beneficiaries until certain conditions are met. For example, if Uncle Pierre creates a trust for Nick's benefit but stipulates that Nick will not get a penny until he gets a Ph.D. in French; Nick is the beneficiary of an accumulation trust.

Under a will, the failure of a gift of property. A gift lapses when the beneficiary dies before the person who made the will, and no alternate has been named. Some states have anti-lapse statutes, which prevent gifts to relatives of the deceased person from lapsing unless the relative has no heirs of his or her own. A lapsed gift becomes part of the residuary estate.

A bypass trust funded with an amount no larger than the personal federal estate tax exemption in the year of death. If the trust grantor leaves property worth more than that amount, it usually goes to the surviving spouse. The trust property passes free from estate tax because of the personal exemption, and the rest is shielded from tax under the surviving spouse's marital deduction.

The court process following a person's death that includes proving the authenticity of the deceased person's will appointing someone to handle the deceased person's affairs identifying and inventorying the deceased person's property paying debts and taxes identifying heirs, and distributing the deceased person's property according to the will or, if there is no will, according to state law. Formal court-supervised probate is a costly, time-consuming process -- a windfall for lawyers -- which is best avoided if possible.
