Regardless of how many names of individuals appear on the property deed, the person who meets the qualifications described in this subsection and proves sole responsibility for the payment of the property taxes on the subject property is the claimant with respect to that property. If 2 or more individuals meet the qualifications in this subsection and share the payment of the rent or the responsibility for the payment of the property taxes, each individual may apply on the basis of the rent paid or the property taxes levied on the homestead that reflect the ownership percentage of the claimant and the claimant's household.

If 2 or more individuals claim the same property, the matter must be referred to the State Tax Assessor, whose decision is final. Ownership of a homestead under this chapter may be by fee, by life tenancy, by bond for deed, as mortgagee or by any other possessory interest in which the owner is personally responsible for the tax for which a refund is claimed.
