Section 1-403. [Pleadings; When Parties Bound by Others; Notice.]
In formal proceedings involving trusts or estates of decedents, minors, protected persons, or incapacitated persons, and in judicially supervised settlements, the following apply:
(1) Interests to be affected shall be described in pleadings which give reasonable information to owners by name or class, by reference to the instrument creating the interests, or in other appropriate manner.
(2) Persons are bound by orders binding others in the following cases:
(i) Orders binding the sole holder or all co-holders of a power of revocation or a presently exercisable general power of appointment, including one in the form of a power of amendment, or a presently exercisable power to appoint among a class of appointees which is broader than the class of those persons who would take in default of the exercise of such power, bind other persons to the extent their interests as objects, takers in default, or otherwise are subject to the power.
(ii) To the extent there is no conflict of interest between them or among persons represented, orders binding a conservator bind the person whose estate the conservator controls; orders binding a guardian bind the protected person or ward if no conservator has been appointed; orders binding a trustee bind beneficiaries of the trust in proceedings to probate a will establishing or adding to a trust, to review the acts or accounts of a prior fiduciary and in proceedings involving creditors or other third parties; and orders binding a personal representative bind persons interested in the undistributed assets of a decedent’s estate in actions or proceedings by or against the estate. If there is no conflict of interest and no conservator or guardian has been appointed, a parent may represent a minor child.
(iii) An unborn or unascertained person who is not otherwise represented is bound by an order to the extent the person’s interest is adequately represented by another party having a substantially identical interest in the proceeding.
(3) Notice is required as follows:
(i) Notice as prescribed by section 1-401 shall be given to every interested person or to one who can bind an interested person as described in (2)(i) or (2)(ii) above. Notice may be given both to a person and to another who may bind such person.
(ii) Notice is given to unborn or unascertained persons, who are not represented under (2)(i) or (2)(ii), by giving notice to all known persons whose interest in the proceedings are substantially identical to those of the unborn or unascertained persons.
