When you get a lawyer, if you have a copy of your previous submission you can give it too the lawyer so they can have an idea about what to do. God bless!
Sometimes legal aid lawyers take on tooo much and you end up doing the work but luckily you were able to read and make the necessary corrections for your file. I hope it goes well for you
I won't say that because my lawyer was very helpful and always responded to my emails and calls. She was very nice and informative. Not all lawyers are greedy
You don't need to update unless you have something you think would strengthen your case or any changes in your situation. For instance, if you start working, change job, volunteer or support letters etc..
