Practice Relating to Rule 82. Recording of the Placement of Landmines
The UK LOAC Pamphlet (1981), under the heading “Future Developments”, considers the possibility of a treaty imposing “an obligation to record minefields and to fit remotely delivered mines with self-neutralising mechanisms or to record their location”. 
United Kingdom, The Law of Armed Conflict, D/DAT/13/35/66, Army Code 71130 (Revised 1981), Ministry of Defence, prepared under the Direction of The Chief of the General Staff, 1981, Section 11, p. 40, § 4(b).
The UK LOAC Manual (2004) states:
The recording of information about minefields, mined areas and mines (as well as booby-traps and other devices) is mandatory and is to be done as follows:
a. Except in the case of remotelydelivered mines, locations are to be “specified accurately by relation to the coordinates of at least two reference points and the estimated dimensions of the area containing these weapons in relation to those reference points”;
b. “Maps, diagrams or other records shall be made in such a way as to indicate the location of minefields, mined areas, booby-traps and other devices in relation to reference points, and these records shall also indicate their perimeters and extent”;
c. For the purposes of detection and clearance of mines, booby-traps and other devices, the records are also to contain “complete information on the type, number, emplacing method, type of fuse and life time, date and time of laying, antihandling devices (if any) and other relevant information on all these weapons laid. Whenever feasible the minefield record shall show the exact location of every mine, except in row minefields when the row location is sufficient. The precise location and operating mechanism of each booby-trap laid shall be individually recorded”;
d. In the case of remotelydelivered mines, the estimated location and area is to be “specified by coordinates of reference points (normally corner points) and shall be ascertained and when feasible marked on the ground at the earliest opportunity. The total number and type of mines laid, the date and time of laying and the selfdestruction time periods” are also to be recorded.
e. Copies of records are to be “held at a level of command sufficient to guarantee their safety as far as possible”.

In its chapter on negotiations between belligerents, the manual states:
Although no rules exist as to the form or contents of a capitulation, for the avoidance of doubt, it should be in writing and contain in the most precise and unequivocal words, the conditions which are to be observed. In particular, the agreement should state:
g. information on minefields and other defence installations.
