The partition so made vests a title in fee simple in the persons to whom the several shares are allotted, as fully and completely as if each had conveyed to the others; but if any fraud or undue influence be employed by any of the parties to obtain an unfair partition or allotment, such partition may be annulled by the circuit court, on a complaint filed within five years after the allotment.
