A trust that allows couples to reduce or avoid estate taxes. Each spouse puts his or her property in an AB trust. When the first spouse dies, his or her half of the property goes to the beneficiaries named in the trust -- commonly, the grown children of the couple -- with the crucial condition that the surviving spouse has the right to use the property for life and is entitled to any income it generates. The surviving spouse may even be allowed to spend principal in certain circumstances. When the surviving spouse dies, the property passes to the trust beneficiaries. It is not considered part of the second spouse's estate for estate tax purposes. Using this kind of trust keeps the second spouse's taxable estate half the size it would be if the property were left directly to the spouse. This type of trust is also known as a bypass or credit shelter trust.

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.'

Convincing a probate court that a document is truly the deceased person's will. Usually this is a simple formality that the executor or administrator easily satisfies by showing that the will was signed and dated by the deceased person in front of two or more witnesses. When the will is holographic -- that is, completely handwritten by the deceased and not witnessed, it is still valid in many states if the executor can produce relatives and friends to testify that the handwriting is that of the deceased.

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 document given to an executor by the probate court, authorizing the executor to settle the estate according to either a will or the state's intestate succession laws.

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.
