There are various ways to re-obtain German citizenship. For example, Sec. 13 of the German Nationality Act provides a facilitated process through which former citizens may seek re-instatement.

However, that procedure is only available if an applicant can demonstrate that he or she (a) would have been granted a Retention Certificate (had a timely application been made), and (b) maintains sufficient ties to Germany that still exist today.  Read more about dual citizenship and re-obtaining German citizenship.
