(i) A person ceases to be actually dependent when his or her income from all sources exclusive of workers' compensation income benefits is such that, if it had existed at the time as of which the original determination of actual dependency was made, it would not have supported a finding of dependency.
In any event, if the present annual income of an actual dependent person including workers' compensation income benefits at any time exceeds the total annual support received by the person from the deceased employee, the workers' compensation benefits shall be reduced so that the total annual income is no greater than such amount of annual support received from the deceased employee. In all cases, a person found to be actually dependent shall be presumed to be no longer actually dependent three (3) years after each time as of which the person was found to be actually dependent. This presumption may be overcome by proof of continued actual dependency as defined in this subsection, but full payments shall not be suspended during the pendency of any proceeding to determine dependency.
