Indiana Code Title 29. Probate § 29-1-17-3

Sec. 3. (a) Except as provided in subsection (b) hereof, shares of the distributees shall abate, for the payment of claims, legacies, the allowance provided by IC 29-1-4-1, the shares of pretermitted heirs or the share of the surviving spouse who elects to take against the will, without any preference or priority as between real and personal property, in the following order:

A general devise charged on any specific property or fund shall, for purposes of abatement be deemed property specifically devised to the extent of the value of the thing on which it is charged.  Upon the failure or insufficiency of the thing on which it is charged, it shall be deemed property not specifically devised to the extent of such failure or insufficiency.

(b) If the provisions of the will or the testamentary plan or the express or implied purpose of the devise would be defeated by the order of abatement stated in subsection (a) hereof, the shares of distributees shall abate in such other manner as may be found necessary to give effect to the intention of the testator.
