Delaware Code Title 25. Property § 1103. Marking and bounding lands;  procedure

(a) Any person seised of any estate in possession, reversion or remainder, or possessed of any term, not less than 15 years, in any lands, the bounds of which are unknown or are in danger of being lost, may apply to the Superior Court in the county where the lands are situate for a commission to mark and bound the estate.  The Court may issue the commission to any 5 persons agreed on by the parties or appointed by the Court, but no surveyor shall be appointed on such commission.

(b) Three months notice of the application shall be given by advertisements posted at the courthouse door of the county and at 5 public places of the 100 where the land lies, and also delivered to the persons in possession of the adjoining lands or left at their dwellings, and to the owners of such lands, if within the State.  If the lands are unoccupied or the owners unknown, the Court may direct the service or the publication of notice, as shall be judged proper.
