Joint Rights. Unless restricted by some further word, conjunct rights of fee in the husband and wife belong to the husband alone in fee, the wife having only a life estate. Conjunct rights given to a father and unborn children, carry the whole fee to the father, unless words are added expressly limiting the father's estate to his life only. Where the children are born and named in the conveyance of the conjunct right, they take a joint estate with the father in fee.
