Hello,

Welcome to the forum.

That would appear to be a snippet of a "next of kin" 419/Advance Fee scam format. Typically, these scams ask you to step in as next of kin (or in some cases, convince you that you really are the next of kin) for a dead bank account owner.

One major catch is, even if the account existed, posing as next of kin to inherit when you are not next of kin is illegal. It would be considered theft through fraud, worldwide. The other major catch is the fact that the account doesn't exist in the first place.

The scammer just uses that as "backstory" to explain why he needs for you to send him money to pay various bank fees, legal fees, fees for certificates, and various other imaginary fees, which he and his friends pocket. They stop asking for money when you run out or it becomes apparent that you won't pay any more. These frauds often involve elaborate fake bank websites and people playing various "roles", with different email addresses and phone numbers.
