When a person not the rightful owner of any real estate, shall have any conveyance or other evidence of title thereto, or shall assert any claim, or pretend to have any right of title thereto, which may cast doubt, or suspicion on the title of the real owner, such real owner may file a bill in the chancery court to have such conveyance or other evidence or claim of title cancelled, and such cloud, doubt or suspicion removed from said title, whether such real owner be in possession or not, or be threatened to be disturbed in his possession or not, and whether the defendant be a resident of this state or not. Any person having the equitable title to land may, in like cases, file a bill to divest the legal title out of the person in whom the same may be vested, and to vest the same in the equitable owner. Any person holding or claiming under a tax title lands heretofore or hereafter sold for taxes may proceed hereunder in like manner and may include, as a defendant, any political subdivision of the state, having or asserting any evidence or claim of title adverse to such tax title.
