(c) In computing relocation payments under the Uniform Act, if any member(s) of a household or owner(s) of an unincorporated business, farm, or nonprofit organization is (are) determined to be ineligible because of a failure to be legally present in the United States, no relocation payments may be made to him or her. Any payment(s) for which such household, unincorporated business, farm, or nonprofit organization would otherwise be eligible shall be computed for the household, based on the number of eligible household members and for the unincorporated business, farm, or nonprofit organization, based on the ratio of ownership between eligible and ineligible owners.
