The following persons shall be conclusively presumed to be wholly dependent for support upon a deceased employee:

(1)  A wife upon a husband with whom she lives, or from whom she was living apart for a justifiable cause, or because he had deserted her, or upon whom she is dependent at the time of his death. The findings of the workers’ compensation court upon the questions of justifiable cause and desertion shall be final for the purposes of this chapter.

(2)  A husband upon a wife with whom he lives or upon whom he is dependent at the time of her death.

(3)  A child or children, including adopted and stepchildren, under the age of eighteen (18) years, or over that age but physically or mentally incapacitated from earning, upon the parent with whom he or she is or they are living or upon whom he or she is or they are dependent at the time of the death of that parent, there being no surviving dependent parent. In case there is more than one child who is dependent, the compensation hereunder shall be equally divided among them.
