Is it necessary to use a Kane County Probate Attorney for a Kane County resident or can any Illinois Probate Attorney handle the case ?

I have a friend whose husband died , English is her second language . She needs to hire a new Probate Attorney because she does not feel her current Attorney has her best interest in mind or practice . Her current representation was recommended by a neighbor and started the Probate process . An Administrator has been named . There have been several instances of behavior that have caused my friend to question the loyalty Of her Attorney and wether there is influence behind the scene On behalf of the other side of her case . Her neighbor was a Kane County Judge for 30 years . She is trying to find an Attorney that will fight for her .
