Please sign this to verify ur signature

We were at the Escrow to sign the papers for our new place yesterday. And there was this paper we had to sign. In our opinion, it's weird..

Firstly, the lady raised some issues regarding Derrick's signature as it does not clearly show his name. Yes... In fact, she encountered cases previously where the bank required the person to change his signature for that matter of fact.

So for me, the following list of signature combinations will not be recognised:
"goh", "ella"

In any way, we were told to sign a paper that verifies this as our signature. A little oxymoron i guess, but whatever works..
