The Stages of a Criminal Case from A to Z: What Happens After a Report Is Filed and How Long It Can Take

25.05.2026Reading time: 8 minAuthor: attorney Yuri Arutyunov

A criminal case is a complex and lengthy process that can seriously change a person's life. Once a report has been filed with the police or other authorities, a chain of events begins in which each stage has its own rules, time limits and opportunities for defence. In Moscow, where the workload of law enforcement agencies is high, it is important to understand what will happen next in order to avoid mistakes and seek professional help in good time.

Attorney for criminal cases in Moscow Yuri Ashotovich Arutyunov provides a full range of services to protect citizens' rights at all stages of the proceedings. Early involvement of a specialist often helps to change the course of a case in the client's favour.

Why it is important to know the stages of criminal proceedings

Most people face a criminal case for the first time and have no idea how exactly events unfold. A great deal of time passes between the pre-investigation check and a possible appeal against the sentence. Knowing the stages makes it possible to build the line of defence correctly, gather the necessary documents and avoid typical mistakes that are difficult to correct later.

In the practice of attorney Yuri Ashotovich Arutyunov there have been many cases where timely legal assistance in criminal matters helped to terminate the prosecution at an early stage or to obtain a lenient punishment.

The pre-investigation check: the first stage after a report

Once a crime report has been received, a pre-investigation check begins. This is the period during which police officers or investigative bodies gather the initial materials: they question witnesses, study documents and inspect the scene of the incident. By law, this stage usually lasts from 3 to 30 days, but in complex cases the period may be extended.

At this stage, a person may be a witness, a complainant or already a suspect. It is important to understand that any statements made without an attorney may later be used against you. An attorney for criminal cases in Moscow advises against giving explanations without defence counsel present, especially if there is a risk of becoming a suspect.

During the check, expert examinations may be ordered and documents may be requested from organisations. If there is sufficient material, a decision is made to initiate criminal proceedings. If not, initiation of proceedings is refused. At this stage, an experienced attorney helps to gather evidence of innocence, challenge unlawful actions of officers or obtain a refusal to initiate proceedings.

What to do during the pre-investigation check

You should not ignore summonses to the police station. It is better to attend with an attorney. The specialist will ensure that your rights are respected, help you formulate your position correctly and record any violations by law enforcement officers.

  • Do not give evidence without defence counsel;
  • Record all actions of the officers (video or audio, with their consent or through the attorney);
  • Gather documents and witnesses in your favour;
  • Challenge rulings through the prosecutor or the court.

An attorney's services in criminal cases at this stage often make it possible to avoid the initiation of proceedings and the associated stress and restrictions.

Initiation of criminal proceedings and the status of participants

If the check reveals signs of a crime, a ruling to initiate criminal proceedings is issued. From this moment, the key figures appear: the suspect, the victim and the witnesses. In Moscow, such rulings are issued by investigators of the Investigative Committee, inquiry officers of the Ministry of Internal Affairs or other authorised persons.

After proceedings have been initiated, a preventive measure may be imposed on the person: a written undertaking not to leave, house arrest, bail or remand in custody. Each option seriously affects a person's life. An attorney defending the accused helps to obtain the most lenient measure or to have it changed.

At this stage, searches, seizures of documents and interrogations begin. It is important that all procedural actions are carried out strictly in accordance with the Code of Criminal Procedure of the Russian Federation, with defence counsel taking part.

Time limits at the preliminary investigation stage

In most cases, the preliminary investigation must be completed within 2 months. However, this period is regularly extended to 6 months, a year or even longer in particularly complex cases. The practice of attorney Yuri Ashotovich Arutyunov includes cases that lasted more than two years.

During the investigation, evidence is gathered, confrontations and expert examinations are conducted, and all participants are questioned. The suspect becomes the accused once charges have been brought.

The preliminary investigation: key actions and rights

At the preliminary investigation stage, the investigator carries out a large volume of work. Investigative actions are conducted: interrogations, searches, and the ordering of forensic examinations (medical, handwriting, vehicle-related and others). The accused has the right to give evidence, file motions and review the case materials.

One of the important moments is the completion of the investigation and the presentation of the materials for review. At this stage, the attorney carefully studies all volumes of the case, identifies violations and prepares a position for the court.

If the case concerns a road traffic accident, bodily harm, theft, fraud or other articles of the Criminal Code of the Russian Federation, the classification of the acts and the body of evidence are of decisive importance. A good attorney for criminal cases in Moscow helps to classify the acts correctly or to find grounds for reclassification to a less serious article.

Typical mistakes at the investigation stage

Many accused persons give detailed evidence without consulting defence counsel, agree to all the expert examinations proposed by the investigation or do not challenge unlawful actions. This significantly complicates the defence in court.

  • Signing records without reading them;
  • Declining an attorney at the first interrogations;
  • Failing to file motions for additional expert examinations in time;
  • Breaching a written undertaking not to leave.

Professional legal assistance in criminal cases helps to avoid such mistakes and to actively influence the course of the investigation.

The trial: how a criminal case is heard in court

Once the case has been sent to court, the court proceedings begin. In Moscow, criminal cases are heard by district courts and, for grave crimes, by the Moscow City Court. The judicial investigation includes the examination of evidence, the questioning of witnesses and the closing arguments of the parties.

The court may deliver an acquittal, impose a punishment, terminate the case on various grounds or return it for further investigation. At this stage, the attorney's work in the criminal proceedings is particularly important — speeches in the closing arguments, filing motions, presenting additional evidence.

By law, a case is heard by the court of first instance within up to 2 months for simple cases, but in practice this often takes from 3 to 12 months or more.

Preventive measures and their impact on life

Throughout the proceedings, restrictions may apply: a prohibition on certain actions, house arrest, detention in a pre-trial detention centre. Each option requires separate work by the attorney to change or cancel the preventive measure.

Appeal, cassation and supervisory review: options for challenging the sentence

Parties who disagree with the sentence have the right to appeal within 10 days. The court of appeal reviews the lawfulness and validity of the decision. The cassation and supervisory instances follow.

An attorney for criminal cases in Moscow continues working after the sentence has been passed, helping to prepare appeals and present additional arguments.

How long a criminal case lasts on average

From the moment of the report to the sentence entering into force, it usually takes from 6 months to 2-3 years. In particularly complex cases, the process may drag on for 4-5 years or more. The actual time frames depend on the category of the case, the number of episodes, the workload of the authorities and the position of the defence.

Why you need an attorney for criminal cases at every stage

Defending yourself rarely leads to a good result. A professional attorney knows the nuances of the Code of Criminal Procedure of the Russian Federation, has experience dealing with investigators and judges in Moscow, knows how to work with evidence and protects the client's rights.

  • Consultations at any stage;

  • Appealing decisions;
  • Defence in courts of all instances.
