§ 2-6-106 — Antilapse; deceased devisees; class gifts

If a devisee who is a grandparent or a lineal descendent of a
grandparent of the testator is dead at the time of execution of
the will, fails to survive the testator, or is treated as if he
predeceased the testator, the issue of the deceased devisee take
in place of the deceased devisee and if they are all of the same
degree of kinship to the devisee they take equally, but if of
unequal degree then those of more remote degree take per
stirpes. One who would have been a devisee under a class gift if
he had survived the testator is treated as a devisee for
purposes of this section whether his death occurred before or
after the execution of the will.
