If you have been in a serious pedestrian accident you can hire the lawyer of your choice outside of where the accident took place. When it comes to hiring a lawyer, where they are located is not the top priority. With today's technology, so much of the communication between a lawyer and their client is done over the phone and/or email.
The most important thing to think about when hiring a lawyer is how much experience they have in handling cases like yours. Also, find out what their reputation is in the community and see if they offer any written materials or videos that provide you with their level of expertise.
