You could petition to open an estate for your mother. That will either result in you becoming person rep and you can subpoena a copy of the will from the husband OR the husband will cough up the will and open the estate based upon the will. However, it's possible that your mother's assets passed to him outside of the terms of the will via joint accounts, beneficiary forms, etc.
