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.

Under a trust, the situation that occurs when the sole trustee and the sole beneficiary are the same person or institution. Then, there's no longer the separation between the trustee's legal ownership of trust property from the beneficiary's interest. The trust 'merges' and ceases to exist.

Any trust that imposes limits or controls over the rights of trust beneficiaries. These trusts include (1) special needs trusts designed to assist people who have special physical, emotional or other requirements, (2) spendthrift trusts designed to prevent a beneficiary from wasting the trust principal; and (3) sprinkling trusts that allow the trustee to decide how to distribute trust income or principal among the beneficiaries.

1) An alternate beneficiary named in a will, trust or other document. 2) Any person entitled to property under a will if one or more prior conditions are satisfied. For example, if Fred is entitled to take property under a will only if he's married at the time of the will maker's death, Fred is a contingent beneficiary. Similarly, if Ellen is named to receive a house only in the event her mother, who has been named to live in the house, moves out of it, Ellen is a contingent beneficiary.
