Evidence to Keep After Financial Fraud
Good evidence helps your bank, provider and the police act. What to save after financial fraud, how to capture it safely, and how to build a simple timeline.

After fraud, it is natural to want to delete everything and move on. Before you do, save the evidence. It is what lets your bank, provider and the police trace money and connect cases.
What to keep
- Payments: transaction IDs, amounts, dates, times, recipient names, numbers and accounts.
- Messages: chats, emails and texts, with the sender's number or address visible.
- Calls: call log screenshots with numbers and times.
- Websites and apps: addresses, screenshots and app names.
- Profiles: usernames and profile links of scammers.
- Crypto: wallet addresses and transaction hashes.
How to capture it
- Take screenshots before blocking or reporting accounts.
- Export chats where the app allows.
- Download statements from your bank or provider.
- Save everything in one folder and back it up.
