Sec. 25. (a) In accordance with IC 32-17-13, a transfer on death transfer may be subject to the payment of the surviving spouse and family allowances under IC 29-1-4-1.

(b) A beneficiary designation designating the children of the owner or children of any other person as a class and not by name includes all children of the person regardless of whether the child is born or adopted before or after the beneficiary designation is made.

(c) Except as provided in subsection (d), a child of the owner born or adopted after the owner makes a beneficiary designation that names another child of the owner as the beneficiary is entitled to receive a fractional share of the property that would otherwise be transferred to the named beneficiary.  The share of the property to which each child of the owner is entitled to receive is expressed as a fraction in which the numerator is one (1) and the denominator is the total number of the owner's children.

(d) A beneficiary designation or a governing instrument may provide that subsection (c) does not apply to an owner's beneficiary designation.  In addition, a transferring entity is not obligated to apply subsection (c) to property registered in beneficiary form.

(e) If a beneficiary designation does not name any child of the owner as the designated beneficiary with respect to a particular property interest, a child of the owner born or adopted after the owner makes the beneficiary designation is not entitled to any share of the property interest subject to the designation.
