When any owner of a farm, the name of which has been recorded in the office of the register of deeds of the county in which the farm is located according to the law in effect at the time of recording, transfers by deed or otherwise the whole of such farm, such transfer may include the registered name thereof; but if the owner shall transfer only a portion of such farm, then, in the event, the registered name thereof shall not be transferred to the purchaser unless so stated in the deed or conveyance. ?(1915, c. 108, s. 4; C.S., s. 4009; 2012-18, s. 1.13.)
