I need to provide instructions to my oversea bank. I filled out the form and sent it to the bank.
They called me on my account's phone number to let me know that the form was rejected because "my signature doesn't look similar enough to the signature in my account". I was then told to guess what the account's signature looked liked and try to reproduce it.
Unfortunately, my signature changes over time. In fact, I can't even reliably produce 2 identical signatures one after the other, so for me to guess and reproduce what my signature looked like in their 5 years old records is next to impossible.
I am thinking of sending a copy of my passport and try to reproduce that signature, but I don't know if it will be accepted.
The bank has no branch in my country so the only alternative I can think of is to fly to the bank's country and handle the transaction in person. Of course this would be expensive and extremely inconvenient at this point.
Is there another way I can prove my identity to the bank? Maybe a legal procedure like signing in front of a notary?
