Please tell me how to proceed with an unjust enrichment return claim lawsuit.

I have confirmed that you have inquired about how to proceed with an unjust enrichment return claim lawsuit.

As in the situation you inquired about, if you wish to recover the amount unjustly transferred due to a mistaken transfer, you can recover the amount through an unjust enrichment return claim lawsuit.

Unjust enrichment refers to the profit that arises when another person's property is illegally acquired.

A mistaken transfer is a monetary profit arising from an unintended transaction, so the recipient has an obligation to return it.

Before proceeding with the unjust enrichment return claim lawsuit, you must first request the return of the amount of the mistaken transfer from the other party.

You said you have already made a request, but it appears the other party cannot be reached.

In this case, you may also consider sending a certified mail.

Certified mail can give legal pressure to the other party and can be used as favorable evidence in subsequent legal procedures.

If the other party refuses to return or cannot be reached, you can file an unjust enrichment return claim lawsuit.

To proceed with the lawsuit, you must prepare evidence such as the transfer receipt, account number, and account transfer details.

Through this, the court can recognize that the relevant transfer occurred by mistake and order the other party to return it.

However, if the other party does not return the amount or if return is impossible, additional legal procedures may be needed.

In this case, the court can impose not only the return of the amount but also interest on the unreturned amount.

Through these procedures, you can recover the unjustly transferred amount, and it is good to receive the help of a civil specialist attorney before the lawsuit.
