Black’s1 defines “title” in the real property sense as the “formal right of ownership of property. Title is the means whereby the owner of lands has the just possession of his property; the union of all the elements which constitute ownership.” This definition implicates both the written evidence of title, i.e. a deed, and the physical evidence of title, i.e. occupation.
Just to be sure we are all on the same page: a written document such as a deed, that purports to convey title to the property described therein, is merely evidence of title; it’s not proof of title. The document may convey nothing at all or may not describe the property that was actually conveyed.
