A 10-lot subdivision was approved by the proper governmental authority. The authority's action was pursuant to a map filed by Diaz, which included an undesignated parcel in addition to the 10 numbered lots. The undesignated parcel is differently shaped and somewhat larger than any one of the numbered lots. Subdivision building restrictions were imposed on "all the lots shown on said map." Diaz contracts to sell the unnumbered lot, described by metes and bounds, to Butts. Is title to the parcel marketable?
Yes, because the undesignated parcel is not a lot to which the subdivision building restrictions apply.  Yes, because the undesignated parcel is not part of the subdivision.  No, because the undesignated parcel has never been approved by the proper governmental authority.  No, because the map leaves it uncertain as to whether the unnumbered lot is subject to the building restrictions.
