My father passed away recently and my father had a will but I don't know who the lawyer is and one brother is not trying to get anything taken care of

I'm sorry to hear about your father's passing.  If you think that your father has assets that must pass by virtue of the contents of his will, then initiating a probate administration of his estate is appropriate.  Do you know whether your brother has the will?  If he does, you can file a petition with the court directing him to produce the will and open the probate.  If you don't know who has the will, you can always seek to have yourself appointed as the administrator of the estate.  In any event, you may want to file a caveat with the register of wills to ensure that nothing happens with your father's estate without you knowing in advance.  You should consider retaining an attorney to assist you with your rights and with the estate.
