my husband and i recently found out that his estranged father died in 2000. his mother (my husband's grandmother) supposedly wrote my husband into her will and he would be entitled to his share upon his father's death. we know little about her. they have been estranged for about 30 years. from what weknow, she died in oklahoma and we live in texas. how do we find out what her will said and what he is entitled to without hiring an lawyer?
