Dear @Presly,
Welcome back to the Wefugees Community and thank you for reaching out to us again.
I’m not a lawyer, but I tried to make some research. I read that, in general, lawyers have to hand out the file including all of your documents. However, if the bill is not fully paid yet, they might be allowed to hold them back for the time being. I would highly recommend to discuss this with your new lawyer - I am sure he/she can help to clarify here (also regarding the total amount your old lawyer requests). Good luck and please don’t hesitate to get back to us with any further questions.
All the best,
Meike
