All persons in the territory of the belligerent or in territory occupied by the belligerent must be enabled to transmit to and receive from members of their families, wherever they may be, news of a strictly personal nature. There must be no undue delay in forwarding such correspondence.
1116. Censorship
This correspondence is liable to censorship by the belligerent concerned. If the belligerents consider it necessary to restrict such correspondence the restrictions must be limited to prescribing the compulsory use of standard forms containing 25 freely chosen words, to be despatched at the rate of not less than one a month.
1117. Family enquiries
Belligerents must facilitate enquiries by members of families dispersed as a result of the war, with the object of renewing contact between them. They must also facilitate the work of approved organizations engaged in this task.
