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 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.

The portion of a deceased person's estate that a spouse is entitled to claim under state law. The statutory share is usually one-third or one-half of the deceased spouse's property, but in some states the exact amount of the spouse's share depends on whether or not the couple has young children and, in a few states, on how long the couple was married. In most states, if the deceased spouse left a will, the surviving spouse must choose either what the will provides or the statutory share. Sometimes the statutory share is known by its more arcane legal name, dower and curtesy, or as a forced or elective share.

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.

The inability, as determined by a court, to handle one's own personal or financial affairs. A court may declare that a person is incompetent after a hearing at which the person is present and/or represented by an attorney. A finding of incompetence may lead to the appointment of a conservator to manage the person's affairs. Also known as 'incompetency.'
