Formulation of a criminal complaint in cases of crypto fraud

Legally sound criminal complaint filed by a lawyer

Filing a criminal complaint for crypto fraud is more than just filling out a form at the local police station. In order for a complaint to be taken seriously by law enforcement, forwarded to the right department and not dismissed for lack of grounds, the facts of the case must be precisely formulated, evidence must be cleanly prepared and the forensic blockchain trail must be comprehensibly documented.

This legal work is being handled by a specialist in crypto and cybercrime law. lawyer. Crypto Investigation provides the forensic basis; the lawyer uses this to formulate a legally sound complaint and submits it to the relevant authority.

Important note: Crypto Investigation does not undertake criminal prosecution.

Crypto Investigation is a crypto forensics company – not a legal services provider. We analyze blockchain transactions, track stolen funds, and prepare forensic reports admissible in court. We do not provide legal representation in criminal proceedings.

Once you decide to file a criminal complaint, we will put you in touch with our lawyer. From this point on, the lawyer is your legal contact person. The complaint is drafted and filed by him, communication with the investigating authorities is handled through the law firm, and the legal fees are billed separately.

This clear division of tasks protects you in two ways.You get the forensic depth of crypto specialists and the legal certainty of a specialized lawyer – without any blurring of responsibilities.

Why a professionally drafted criminal complaint is crucial

German law enforcement agencies process thousands of reports of crypto fraud every year. However, many of these reports are quickly closed – not because no crime has been committed, but because the report is formally or substantively insufficient to launch a meaningful investigation.

Typical weaknesses of a self-formulated version:

  • Unclear facts: Which sections of the German Criminal Code (StGB) are relevant? Fraud (§ 263), computer fraud (§ 263a), commercial gang fraud, money laundering? The correct formulation of the offense steers the investigation in the right direction.
  • Unstructured evidence processing: Screenshots, wallet addresses, and email histories without a clear connection to each other make the work of the authorities more difficult.
  • Lack of forensic evidence: Without verifiable blockchain analysis, the flow of funds remains opaque to investigators.
  • Wrong authority: Reports that end up with the local police instead of the specialized public prosecutor's office or the cybercrime units waste valuable time.


A complaint prepared by a specialized lawyer circumvents these weaknesses and significantly increases the likelihood of a serious investigation. You can read more about the general requirements in our article.
Reporting crypto fraud – how to file a criminal complaint correctly.

What the lawyer specifically does

The lawyer we have arranged provides – for a separate fee – the following core legal services related to filing a criminal complaint:

1. Legally precise formulation of all facts

The lawyer analyzes the facts from a criminal law perspective and identifies each offense precisely and correctly: commercial fraud (§ 263 para. 3 of the German Criminal Code), computer fraud (§ 263a of the German Criminal Code), organized fraud, money laundering (§ 261 of the German Criminal Code) – often in combination. The correct structure of the offenses is essential to ensure that the report is assigned to the competent specialized public prosecutor's office and does not get lost in general police processing.

2. Structured preparation of all available evidence

Instead of a loose collection, the advertisement is structured as a coherent file – with clearly numbered attachments, references from the advertisement text to the respective evidence, and a chronology comprehensible to investigators. All available evidence is included. Evidence in cases of crypto fraud – Wallet addresses, transaction IDs, platform screenshots, email and chat histories, advertisements, bank documents – integrated in the right place.

3. Addition of the forensic blockchain analysis

The centerpiece of a crypto-related criminal complaint is the forensic report provided by Crypto Investigation. This report documents the complete flow of funds from the victim's wallet to the identified endpoints – including transaction hashes, clustering, cross-chain tracing, and, where applicable, the identification of regulated exchanges as points of reference. Learn more at [link to relevant page]. Blockchain analysis and crypto forensics.

The lawyer attaches this forensic report to the complaint and specifically refers to the forensic findings in the text of the complaint. This provides investigators not only with an allegation of fraud, but also with technically verifiable evidence.

4. Submission to the competent investigating authority

Crypto fraud is often international, frequently involving organized or gang-related activities. Such cases typically fall under the purview of specialized cybercrime prosecutors or specialized police units, such as the Central Cybercrime Unit of the respective state criminal investigation offices. The lawyer files the report with the correct authority based on the facts and jurisdiction – this saves weeks and increases the likelihood of a serious investigation.

What Crypto Investigation contributes to the criminal complaint

Even if the advertisement itself is drafted by the lawyer, the preliminary work by Crypto Investigation is crucial for its quality:

  • Forensic Blockchain Analysis with complete traceability and a report admissible in court
  • Identification of endpoints – Which exchanges, which wallet clusters, which jurisdictions are affected?
  • Structured evidence preparation in a form that the lawyer can directly incorporate into the advertisement
  • Answering technical questions the investigator – at the request and in consultation with the lawyer
  • Real-time monitoring the identified wallets to track fund movements during the process


This preliminary work is the reason why, in practice, reports based on crypto investigative forensics often receive significantly more substantial attention from the investigating authorities.

Costs of filing a legal complaint

The lawyer's fees are paid separately from the forensic fees of Crypto Investigation. The applicable fee schedule is usually the Lawyers' Fees Act (RVG) or an individual fee agreement with the lawyer.

The lawyer will provide you with a transparent fee proposal before accepting your case. Crypto Investigation's forensic costs and legal fees are easy to plan – both items are itemized separately, ensuring you always have a clear overview.

In some cases, legal expenses insurance may also be an option. The lawyer will clarify whether your insurance covers the specific case before accepting the mandate.

When a professionally written advertisement is particularly useful

A professionally prepared criminal complaint is not the only way in every case, but it is particularly recommended in certain situations:

  • Damage amounts starting at approximately 10,000 euros – Here, the potential value of the recovered item justifies the legal effort.
  • Clear path to regulated exchanges – Criminal procedural inquiries are particularly promising there.
  • International constellations – Requests for legal assistance require a sound legal basis.
  • Several victims of the same group of perpetrators – A coordinated advertisement carries more structural weight.
  • Commercial or organized background – Here, special circumstances become relevant that only a specialized lawyer can reliably assess.


Whether your case fits into one of these scenarios will be clarified together in the free initial assessment – before any legal fees are incurred.
