To deliberately prevent someone from inheriting something. This is usually done by a provision in a will stating that someone who would ordinarily inherit property -- a close family member, for example -- should not receive it. In most states, you cannot completely disinherit your spouse; a surviving spouse has the right to claim a portion (usually one-third to one-half) of the deceased spouse's estate. With a few exceptions, however, you can expressly disinherit children.

A certain amount of a deceased person's money to which immediate family members are entitled at the beginning of the probate process. The allowance is meant to help support the surviving spouse and children during the time it takes to probate the estate. The amount is determined by state law and varies greatly from state to state.

For federal estate tax filing purposes, the total of all property owned at death, without regard to any debts or liens against the property or the costs of probate. Taxes are due only on the value of the property the person actually owned (the net estate) plus the amount of any taxable gifts made during life. In a few states, the gross estate is used when computing attorney fees for probating estates; the lawyer gets a percentage of the gross estate.

A person who makes investments. An investor may act either for herself or on behalf of others. A stock broker or mutual fund manager, for instance, makes investments for others who have entrusted her with their money.

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.'

Someone who will inherit property in the future. For instance, if someone dies and leaves his home 'to Alma for life, and then to Barry,' Barry is a remainderman because he will inherit the home in the future, after Alma dies.

Provides that an insured person who lives for the specified endowment period receives the face value of the insurance policy--that is, the amount paid at death. If the policy-holder dies sooner, the beneficiary named in the policy receives the proceeds.

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.
