No date has yet been set for the trial of the 89-year-old retired car worker.
Prosecutors accuse Demjanjuk - who was deported from the US in May - of serving as a guard at the Sobibor camp in Nazi-occupied Poland during World War II.
Demjanjuk says he was a Red Army soldier who spent the war as a Nazi prisoner of war and never hurt anyone.
Doctors cleared the way for formal charges earlier this month, determining that Demjanjuk was fit to stand trial for two 90-minute periods per day.
