Wyo. Stat. § 2-6-106
Current with changes from the 2024 Legislative Session, Acts 1-58, 60-118
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.
