(a) Unless the court finds that a bond is unnecessary and enters an order to that effect, or unless the appointed guardian is a bank or trust company (as defined in IC 28-1-1-3), a guardian must execute and file a bond relating to the duties of the guardian's office. Unless otherwise directed by the court, the bond must be in an amount that is not less than the amount determined under STEP THREE of the following STEPS: STEP ONE: Enter the aggregate value of the guardianship property.
STEP TWO: Add to the amount entered under STEP ONE one (1) year's estimated income.
STEP THREE: From the sum determined under STEP TWO subtract the value of any property that the guardian, by express limitation of power, lacks the power to sell, convey, or encumber without a court order.
