Ind. Code § 16-36-7-34
An advance directive must be interpreted to carry out the known or demonstrable intent of the declarant. The following presumptions apply to an advance directive unless the terms of the advance directive explicitly prevent a presumption from applying:
(3) If an advance directive designates two (2) or more health care representatives and does not specify that:
(B) the health care representatives must act jointly or on a majority vote basis;
each health care representative has concurrent authority to act individually and independently to make health care decisions for the declarant. If two (2) or more health care representatives who are required to act jointly disagree about a health care decision, or if two (2) or more health care representatives who are authorized to act independently give conflicting instructions to a health care provider, the health care provider may decline to comply with the conflicting instructions, and in an urgent or emergency situation, the health care provider may provide treatment consistent with the instructions of one (1) physician or one (1) advanced practice registered nurse who examines or evaluates the declarant.
(4) If:
(B) the later signed advance directive does not explicitly state that one (1) or more of the previous advance directives by the declarant remain in effect;
each previous advance directive is superseded and revoked by the last signed advance directive.
(5) Unless the advance directive explicitly provides otherwise, each health care representative who is designated in an advance directive continues to have authority after the death of the declarant to do the following:
(7) If an advance directive explicitly provides that the authority of one (1) or more health care representatives is to be effective upon the future incapacity, disability, or incompetence of the declarant but if the advance directive does not specify a method or procedure for determining the incapacity, disability, or incompetence of the declarant:
(9) If the advance directive is silent on the issue of compensation for a health care representative designated in the advance directive, then each health care representative is entitled to receive the following:
(B) Reasonable reimbursement from the declarant's property for out-of-pocket expenses actually incurred and paid by the health care representative from the health care representative's own funds in the course of performing services or acts for the declarant under the advance directive.
Any health care representative may waive part or all of the compensation or expense reimbursements that the health care representative would be entitled to receive under the terms of the advance directive or under this subdivision.
(10) If an advance directive explicitly provides that the authority of a health care representative is effective only at times when the declarant is incapacitated or unable to consent to health care, then unless the advance directive explicitly states another procedure:
(12) If:
(C) the declarant is incapacitated or not competent to make personal health care decisions;
then subject to any order of priority explicitly stated in the advance directive, each health care representative designated in the advance directive must be given the opportunity to exercise authority for the declarant.
(14) Notwithstanding any provision in the advance directive, if a declarant is not competent to amend or revoke the declarant's advance directive, then a person who may act as a proxy for the declarant under sections 42 and 43 of this chapter has the right to petition a probate court with jurisdiction over the declarant for any of the following relief:
(D) An order appointing a new or additional health care representative, on the grounds that all health care representatives designated in the advance directive are not reasonably available to act.
Before issuing an order under this subdivision, the court must hold a hearing after notice to the declarant, to each health care representative, and any other person whose rights or authority could be affected by the order, and to any persons who have the highest priority under sections 42 and 43 of this chapter to serve as a proxy for the declarant if an advance directive had not existed. An order issued under this subdivision must be guided by the declarant's best interests and the declarant's known or demonstrable intent.
