A person in prison may generally write and send their own text as a letter. The external publisher or media outlet decides whether to publish it.
Section 86 StVG permits prisoners to correspond in writing with other people and bodies. Section 89 StVG provides for writing materials and, where necessary, paper. Section 87 StVG generally permits letters to be sent and received. A manuscript, a letter to an editor or documents for a publisher therefore initially fall within ordinary correspondence.
Sending a manuscript does not amount to publication approval. The recipient decides whether to accept, edit or publish the text. The prison may inspect correspondence under sections 90 and 90a StVG or withhold an item under the statutory conditions. Send a clearly identified and complete version and keep a copy and proof of the sending date.
