a real mess

my daughter passed away on nov 8, 2005. She was divorced for 5 years but ex lived with her, in her home which was given to her in divorce, until 2 months before her death. ex moved out then and bought new home. Her will named her mother as beneficiary of the whole estate. the estate consisted of her home, property, corvette, jewelry. her mother took it to probate and ex showed up with attorney to contest will, claiming commonlaw. In the meantime, it will be two years in november of this year and this is what has happened so far. Exhusband has gotten court orders to put everything in his name, moved into her home and has just taken over without this estate being setteled or has not gone to court as of this date. her mother paid real estate taxes, utility bills, etc. before he moved in and he has now taken over all bills, etc. her mother has nothing and it was willed to her. her mother has an attorney but there has been little, little communication between the two as they never call, write or let her know what is going on. she is not from texas, where daughter lived, so just went to the attorney's office that made out the will for her daughter in 1996 to do the probate. this attorney stayed with the case when it was probated andcontested and is supposed to be reprensenting the mother but does not communicate AT ALL. the mother is 71 years old, devastated by her daughters suicide and it was her ONLY child. she does not know where to turn but feels this is not legal what the exhusband is doing. can you give me some advice as to what her concourse would be to try and resolve this so she can grieve and have this behind her? should she get a different attorney? will she owe the present attorney if she gets a new one? She is going downhill and is not at all well and this STRESS she is under is taking its toll. Please help///// Thanks
