Section 19
SEC. 19. Application for registration of title may be made by the following persons, namely: First. The person or persons claiming, singly or collectively, to own the legal estate in fee simple. Second. The person or persons claiming, singly or collectively, to have the power of appointing or disposing of the legal estate in fee simple. Third. Infants or other persons under disability may make application by their legally appointed guardians, but the person in whose behalf the application is made shall be named as applicant by the guardian. Fourth. Corporations may make application by any officer duly authorized by vote of the directors. But the authority given to the foregoing four classes of persons is subject to the following provisos: That one or more tenants for a term of years shall not be allowed to make application except jointly with those claiming the reversionary interest in the property which makes up the fee simple at common law. That a mortgagor shall not make application without the consent in writing of the mortgagee. That a married woman shall not make application without the consent in writing of her husband unless she holds the land as her separate property or has a power to appoint the same in fee simple, or has obtained a decree of the court authorizing her to deal with her real estate as though she were sole and unmarried. That one or more tenants claiming undivided shares less than a fee simple in the whole land described in the application shall not make application except jointly with the other tenant owning undivided shares, so that the whole fee shall be represented in the action. But, notwithstanding the foregoing provisos, if the holder of a mortgage, upon the land described in the application does not consent to the making of the application, it may be entered nevertheless and the title registered subject to such mortgage, which may be dealt with or foreclosed as if the land subject to such mortgage had not been registered. But the decree of registration in such case shall state that registration is made subject to such mortgage, describing it, and shall provide that no subsequent certificate shall be issued and no further papers registered relating to such land after a foreclosure of such mortgage.
