The prerequisite for the transfer of the files to the research group of the University of Zurich is the approval of the priests concerned, as the archdiocese announced on Tuesday.
Six of the seven still living priests who moved from the diocese of Chur to the newly built Archdiocese of Vaduz in 1997 have therefore given their consent.
The files in question would now be transmitted in copy to the Diocese of Chur so that they could be included in the study where appropriate.
In November, the archdiocese found that the legal situation in Liechtenstein did not allow the transfer of personnel files to foreign third parties.
The research team of the University of Zurich, which developed the Swiss reappraisal study, had asked for insight into the files of the priests who had belonged to the diocese of Chur before the establishment of the Archdiocese of Vaduz.
The archdiocese was formed in 1997 from the Liechtenstein parts of the Swiss diocese of Chur.
The problem of the Liechtenstein files has already been raised in the research group's report. Accordingly, the files of the former dean's office Liechtenstein were handed over to the Liechtenstein State Archives.
The files of the Diocese of Chur with reference to the Principality of Liechtenstein had been transferred from the Chur Archive to Vaduz.
"This situation presents researchers with a special source problem: For a large part of the investigation period (1950–1997), the territories of the Principality of Liechtenstein belonged to the Diocese of Chur. However, the source situation was subsequently changed in such a way that research into sexual abuse in this region of the diocese is significantly more difficult and sometimes almost impossible," the report said.
