Except as otherwise provided in section 8-41-501(1)(c), a child eighteen years of age or over and a mother, father, grandmother, grandfather, sister, brother, or grandchild who was wholly or partially supported by the deceased employee at the time of death and for a reasonable period of time immediately prior thereto is considered an actual dependent. To be entitled to compensation, such dependents, except as provided in section 8-41-501(1)(c), must prove that they were incapable of or actually disabled from earning their own living. If said incapacity or disability is temporary only, compensation shall be paid only during the period of such temporary incapacity or disability.
