Clarke v. Graham
19 U.S. (6 Wheat.) 577
A power to convey lands must possess the same requisites and observe the same solemnities as are necessary in a deed directly conveying the lands.
A title to lands can only be acquired and lost according to the laws of the state in which they are situate.
The laws of Ohio require all deeds of land to be executed in the presence of two witnesses, and a deed executed in the presence of one witness only is void. A parol exchange of lands or parol evidence that a conveyance should operate as an exchange will not convey any estate or interest in lands.
