Idaho State Statutes - Idaho Attorney Directory

(a) If a testator fails to provide in
his will for any of his children born or adopted after the execution of his
will, the omitted child receives a share in the estate equal in value to that
which he would have received if the testator had died intestate unless:
(1) it appears from the will that the omission was intentional;
(2) when the will was executed the testator had one (1) or more children
and devised substantially all his estate to the other parent of the omitted
child; or
(3) the testator provided for the child by transfer outside the will and
the intent that the transfer be in lieu of a testamentary provision is shown
by statements of the testator or from the amount of the transfer or other
evidence.
(b) If at the time of execution of the will the testator fails to provide
in his will for a living child solely because he believes the child to be
dead, the child receives a share in the estate equal in value to that which he
would have received if the testator had died intestate.
(c) In satisfying a share provided by this section, the devises made by
the will abate as provided in section 15-3-902 of this code.
