I want to file a loan civil lawsuit but I lack evidence.

Even without a loan agreement, you can file a loan civil lawsuit.

However, since you must prove the fact of the loan and its amount, a strategy of gathering as much indirect evidence as possible is needed.

First, you can secure account transfer records to prove the loan amount and transfer date and time.

Also, if there were traces of communication about the loan through messages, even deleted text messages or KakaoTalk conversations can be largely recovered through digital forensic techniques.

Digital forensics refers to the technology of recovering and analyzing data remaining on digital devices such as mobile phones and computers, and using it as evidence in legal disputes such as civil lawsuits or criminal cases.

Additionally, statements from acquaintances who know about the loan circumstances or recordings in which the other party mentioned the loan can be submitted together to enhance credibility.

It is also good to send a content-certified mail before the lawsuit.

Although content-certified mail has no legal binding force, it serves as official documentation notifying the other party of the existence of the claim and the request for repayment, which can be used as important evidence in subsequent lawsuits.

The more insufficient the evidence feels, the better it is to promptly receive assistance from civil attorneys and digital forensics experts.

I hope you achieve the desired results by comprehensively preparing evidence-securing strategies, drafting the loan civil lawsuit complaint, and proof plans tailored to your situation.
