When your lawyer asks you for documents, they are asking you for specific documents, usually from a particular time period.
Give them what they want.
When your attorney asks for a specific document, they want THAT specific document for a reason. Save yourself the headache of giving some other document that you feel is " just as good, " only to have to finally give the orginal document that they originally requested.
I have heard clients say that they are paying their lawyer " Just to do paperwork!"
Well, "yes and no." Documentation is part of the American system. When you own a house, you get a document called a deed, to show ownership. It's not just " Paperwork." That paperwork is worth hundred of thousands or even millions of dollars. For Lawyers, and the legal system, there isn't "just paperwork."
