What fee should i pay? my attorney say he will send me a document that includ a list of all cost expended by his firm on my case as well as the

Hi.  You should consult the contract that you signed when you first hired the attorney.  It should outline all of his fees and what y'all agreed on regarding additional expenses. I can tell you that our firm works on a contingency fee basis, but expenses (like fees for copying, postage, legal research, etc) do come out separately.  So our breakdown would show the contingency fee percentage we agreed on with the client plus any additional expenses (like fees for copying, postage, legal research, etc.).  The attorney should give you a breakdown.  We call that at our office a disbursement statement which outlines the recovery, fees and expenses, leaving the total amount that you will recover.   The attorney should not refuse to give you a statement of that nature.  I hope this information helped.  Best of luck!
