How much do corporate lawyer charge client and how much does it cost to do legal research an attend court hearing to fight a case an dismiss the cas

Unfortunately, the answer to your question regarding the amount of legal fees required to prepare, file and attend a hearing on a motion to dismiss is "it depends".  If the facts of your case are not complex, the case is filed in the State court (as opposed to Federal Court) and the basis for the motion to dismiss is fairly straightforward then the cost could be as minimal as $750-$1000.    If the case is filed in Federal Court and there are legal/factual complexities, it could cost between $2000-$4000.    You will only have twenty days to file an answer to the lawsuit from the date the you are served so you will want to retain an attorney as soon as reasonably possible.
