Ind. Code § 30-4-6-10.5
(a) Except as provided in the terms of a trust, and to the extent there is not a conflict of interest between the representative and the person represented or among those being represented:
(6) a parent may represent and bind the parent's minor, unborn, or not yet adopted child if a guardian for the child has not been appointed;
with regard to a particular question or dispute.
(b) The holder of a general power of appointment, including a general testamentary power of appointment, may represent and bind persons whose interests are subject to the power of appointment, including:
(c) Unless otherwise represented:
(4) a person whose identity or location is unknown and not reasonably ascertainable;
may be represented by and bound by another person who has a substantially identical interest with respect to the particular question or dispute but only to the extent there is not a conflict of interest between the representative and the person represented.
(d) If the court determines that an interest is not represented under this section or that the otherwise available representation might be inadequate, the court may appoint a guardian ad litem to receive notice, give consent, and otherwise represent, bind, and act on behalf of:
(4) a person whose identity or location is unknown.
If not precluded by conflict of interest, a guardian ad litem may be appointed to represent several persons or interests. A guardian ad litem may act on behalf of the person represented with respect to any matter arising under this title, regardless of whether a judicial proceeding concerning the trust is pending. In making decisions, a guardian ad litem may consider general benefits accruing to the living members of the family of the persons represented.
