you don't need the wife to go with you, just take a copies of her id, blue book, a letter from her confirming that you are living with her, and take a copy of your marriage certificate and your passport and bank book just in case they ask you to see it.
Are you leaving her or has she left you, it matters that she has left first, or you will have to pay her some money if you have left her
Or if you have been separated for more than 5 years then you will be ok,she does not need to be there for the divorce but you have to let her know what you are doing
