I have been living in a different state than my family for the last 8 years with verry limited contace with my mother and father brother and sisters. I had a good relationship with my grand parents who recently died, I want to know how to get a copy of their will, Do I call the court house iin the county they lived or died and what divission. They lived in washington county missouri . My immidate family will not give me any information, the one living grand parrent I have has said their was a lot their and it is being spent but she is afraid to go into it to much. A mutiual aquanticence has also called me to let me know that the property part is up for sale.
