A trust in which the income is retained and not paid out to beneficiaries until certain conditions are met.

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 person or institution designated to receive trust property upon the death of a life beneficiary. For example, Jim creates a trust through which his wife Jane receives income for the duration of her life. Their daughter, the final beneficiary, receives the trust principal after Jane's death.

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).
