If Robert K. Naumann or Joseph S. Agnello did not prepare an estate plan for your deceased loved one, probate or other litigation may be unavoidable. Our attorneys have numerous probate matters pending at all times, and we represent Executors, Trustees, and Guardians, as well as heirs and beneficiaries, both in probate and outside probate, in Cook County and in the nearby collar counties. Our experience includes contested estates, creditor settlement and discharge, diverse assets, unconventional wills and codicils, and highly complex heirships.
