"I want to find evidence of my partner's infidelity, but I'm worried it might be illegal." If you resort to illegal methods such as hiring a private investigator or installing a spy app to prove a spouse's misconduct, there is a high risk that you could instead face criminal punishment or that the evidence may not be admitted in court. At Law Firm Jeonjae, we explain lawful ways to collect evidence during consultations, such as card transaction records, black box footage, and applications to preserve CCTV evidence. We also help clients secure evidence through official channels, such as court orders to submit financial transaction information or requests for factual inquiries, so they can proceed with their case safely.
