My father-in-law passed away in a Nursing Home in Minnesota. His home is in a different st and we live in Calif. Where would we need to hire a lawyer?

His daughter was in control of his care and finances but does not communicate with us about his will or if there is one. How much time should we give her. It has taken a month in the past. We only know of his home but don't know his other assets. Should we look for a lawyer in the state that we live in or where is lived the past 4 years or where his home is?
