The person who manages assets owned by a trust under the terms of the trust document. A trustee's purpose is to safeguard the trust and distribute trust income or principal as directed in the trust document. With a simple probate-avoidance living trust, the person who creates the trust is also the trustee.

A surviving spouse's right to receive a set portion of the deceased spouse's estate -- usually one-third to one-half. Dower (not to be confused with a 'dowry') refers to the portion to which a surviving wife is entitled, while curtesy refers to what a man may claim. Until recently, these amounts differed in a number of states. However, because discrimination on the basis of sex is now illegal in most cases, most states have abolished dower and curtesy and generally provide the same benefits regardless of sex -- and this amount is often known simply as the statutory share. Under certain circumstances, a living spouse may not be able to sell or convey property that is subject to the other spouse's dower and curtesy or statutory share rights.

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.

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.

An ownership interest in the minerals contained in a particular parcel of land, with or without ownership of the surface of the land. The owner of mineral rights is usually entitled to either take the minerals from the land himself or receive a royalty from the party that actually extracts the minerals.

A complete listing of all property owned by a deceased person at the time of death. The inventory is filed with the court during probate. The executor or administrator of the estate is responsible for making and filing the inventory.

A child or spouse who is not mentioned in a will and whom the court believes was accidentally overlooked by the person who made the will. For example, a child born or adopted after the will is made may be deemed a pretermitted heir. If the court determines that an heir was accidentally omitted, that heir is entitled to receive the same share of the estate as she would have if the deceased had died without a will. A pretermitted heir is sometimes called an 'omitted heir.'
