How to Add or Expand a Criminal Complaint
“I’ve found new information – but I don’t know what to do”
“I realized only later, after going through my emails, that there was another person involved. I didn’t mention him in the original report. Now I’m worried I’ve messed something up.”
This happens more often than you think. A criminal complaint doesn’t have to be perfect from the start. If new facts or evidence come to light, you can and should submit an addition. But it must be done properly, on time – and with a clear understanding of the rules.

✏️ Addition vs. Expansion: what’s the difference?
Addition – you’re providing new information related to the same incident or person
Expansion – you’re identifying new persons, acts, or cases not mentioned before
Both are valid – but it’s important to clearly and specifically define them so the police can work with them.
🧾 What the addition should include:
✅ A description of new facts or evidence
✅ How they relate to the original complaint
✅ Attachments (e.g. records, screenshots, emails)
✅ The date and ID of the original complaint
⚠️ Risks of informal additions:
❌ The police might not link the letter to the file
❌ It won’t be included in the investigation
❌ Key information might be overlooked
We recommend a formal written format, data mailbox or registered mail – ideally with legal consultation.
🧑⚖️ Lawyer’s recommendation:
✅ Don’t wait if you have new information
✅ Structure and write the addition clearly
✅ Don’t rely on the police to “figure it out” themselves
✅ I can help you formulate it and plan your evidence strategy
One sentence can change the course of the case
📌 New information can prompt the police to reconsider – but only if it’s clear, properly worded, and delivered on time.
