I have an attorney in county of marital residence but my child and I are living in another county now, can I get case moved to county where we now liv

It sounds like you are trying to change the venue of the case to another county. Whether you can move your case (or change venue) will depend on a number of factors, such as the type of case you have pending, and the reason that you give the court for moving the case, the location of the other party, whether the other party objects to the motion, etc.  Since you say that you have an attorney already on your case in the first county, you should ask him or her about a motion to change venue.  Since they have been working the case already, they will have the information necessary to advise you fully regarding your chances of getting the court to change the venue.
