How do I get a lawyer if I live in NJ And she lives in PA.

You may want to retain a lawyer in the child's home state.  The child's home state is the state where the child lives on the date the case is filed or within the six months before the case started.  In terms of finding a lawyer, you may contact the local Bar Association for referrals.   I would like to further assist you with your child custody matter, but require more information. The attorneys at Weinberger Law Group offer a free initial consultation.  We are happy to gather more information during the consultation to better guide you through your next steps.  Call (855) 545 - 9323 to set up an appointment or for more information.
