In those cases where a landowner files suit alleging that the Government took his property or an interest therein, a litigation report should be furnished in accordance with ER 1180-1-1. Litigation reports will be submitted in quadruplicate in cases involving military installations, and in triplicate in cases involving civil works. District and Division Engineers will furnish an additional copy direct to the local United States Attorney in actions in a United States District Court. In addition to the information required by ER 1180-1-1, there will be furnished preliminary certificates of title to properties subject to the taking, covering a period of search of at least 25 years prior to initiation of the action, and indicating the date of acquisition of the plaintiff's interest. Certificates may be procured commercially, or may be prepared by a staff attorney.

(2) Statement as to any outstanding clearance easement directives, including criteria for approach and transition zones, status of negotiations, and copies of appraisal reports;
(3) Statement that all acquisition of clearance easements has been stopped, unless their prompt acquisition is necessary to provide for current flight operation; and
(4) Recommendation that there be included in the estate, in the event of settlement, provisions for the clearance of existing obstructions and prohibition against future obstructions, provided that circumstances will permit a delay in the acquistion of a clearance easement until completion of the litigation.
