Victim of a criminal offence: reporting and private accessory prosecution

Rights of injured parties, private accessory prosecution (Nebenklage) and the adhesion procedure (Adhäsionsverfahren).

1What is it about?

Victims of a criminal offence have extensive rights in criminal proceedings. You can report the offence (§ 158 StPO), file a criminal complaint (Strafantrag) within three months in the case of offences prosecuted only on complaint (§ 77b StGB) and, in certain cases, join the proceedings as a private accessory prosecutor (Nebenkläger) (§ 395 StPO).

Private accessory prosecutors are active participants in the proceedings. They may be present at the main hearing, ask questions, file motions for evidence to be taken and lodge appeals (§ 397 StPO). Relatives of persons killed may also join. In addition, claims for damages and compensation for pain and suffering can be asserted in the adhesion procedure (§§ 403 ff. StPO).

2Typical case scenarios

  • Bodily harm, threats, stalking or domestic violence.
  • Sexual offences and other offences against sexual self-determination.
  • Relatives of a person killed who act as private accessory prosecutors.
  • Offences motivated by hatred or discrimination.
  • Fraud or property offences causing substantial loss.
  • Continuing investigations in which you need access to the case file.

3Frequently asked questions

Who can become a private accessory prosecutor?

Injured parties of certain offences, such as sexual and violent offences, and relatives of persons killed (§ 395 StPO). Joining is possible at any stage of the proceedings.

Who bears the costs?

In certain cases the court appoints legal counsel at the expense of the state (§ 397a StPO). Otherwise, legal aid (Prozesskostenhilfe) or reimbursement of costs by the convicted person may come into consideration.

What is psychosocial support during proceedings?

Professional support throughout the proceedings that offers information, stabilisation and accompaniment to appointments (§ 406g StPO). It is free of charge under certain conditions.

What can I do if the proceedings are discontinued?

Injured parties can lodge a complaint and, in some circumstances, bring a procedure to compel prosecution (Klageerzwingungsverfahren) (§ 172 StPO).
