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.'

A will that is created in a way that allows a probate court to easily accept it as the true will of the person who has died. In most states, a will is self-proving when two witnesses sign under penalty of perjury that they observed the willmaker sign it and that he told them it was his will. If no one contests the validity of the will, the probate court will accept the will without hearing the testimony of the witnesses or other evidence. To make a self-proving will in other states, the willmaker and one or more witnesses must sign an affidavit (sworn statement) before a notary public certifying that the will is genuine and that all willmaking formalities have been observed.

The legal authority to decide who will receive someone else's property, usually property held in a trust. Most trustees can distribute the income from a trust only according to the terms of the trust, but a trustee with a power of appointment can choose the beneficiaries, sometimes from a list of candidates specified by the grantor. For example, Karin creates a trust with power of appointment to benefit either the local art museum, symphony, library or park, depending on the trustee's assessment of need.
