It does not really matter if you go on your own , all that matters is you have the 20 documents spread evenly between your spouse and yourself.

Worry not it's not as bad as you might be thinking.

I got my a week ago and i was there on my own.

All i can advise is that you do not need a solicitor to check the evidence you have.

Just gather all the document as stipulated on the form and you will be fine.
