211.18—Action by claimant.
Real estate claims may be presented by the owner of the property or his duly authorized agent or legal representative. The word “owner”, as so used, includes lessees, mortgagors, and conditional vendees, but does not include mortgagees, conditional vendors, and others having title for purposes of security only. The claim, if filed by an agent or legal representative, should show the title of the person signing and be accompanied by evidence of the appointment of such person as agent, executor, administrator, guardian, or other fiduciary.
