Why would you feel the need to change your name back to your maiden name by deed poll. Surely a solicitor would have told you that it was unnecessary, you could have just started using your maiden name without the expense you have been through.
Secondly, the name used on the divorce petition is the name you were known by whilst you were married, it doesn't matter what you call yourself now, as long as it isn't to commit an offence or defraud someone.
your job title really is irrelevant, as you could change jobs at any time, so dont worry about trivial details like these.
As long as the details about wedding dates,who you are and the reasons for the divorce, eg breakdown of marriage, adultery etc are correct, you shouldn't have any problems.
Hope everything goes smoothly for you
