Husband and wife may convey or transfer real or personal property directly, the one to the other, without the intervention of a third person; and may make partition or division of any real property held by them as tenants in common, joint tenants or tenants by the entireties. If so expressed in the instrument of partition or division, such instrument bars the wife's right to dower in such property, and also, if so expressed, the husband's tenancy by curtesy.
