Completing tomorrow, however...

Hi folks,

I'm just looking for some advice, so I can best prepare myself for whatever s**t storm is about to be laid upon me.

We exchanged on Tuesday with completion going ahead tomorrow. However, I just received a message from the solicitor asking questions around the witness on the mortgage deed (which was submitted and accepted by the solicitor about a month ago).

We had a neighbour sign as a witness for us but instead of using his full first name, he used the short version (e.g. Instead of "Samuel", put "Sam"). He also put "W.P" before his signature, which after asking him what that means, said it's "without prejudice".

I've gone back to the solicitor with the information. But knowing them, they will contact me tomorrow on the day rather than today to say something needs to be redone.

I guess what I'm asking is could this mean that things won't be going ahead? could the mortgage be refused off the back of this?

***UPDATE*** Solicitor confirmed that there is no issue, it was just needed in writing for if the Land Registry challenged anything.
