My husband and I have had Guardianship (through Indiana) since June 2005 of my 2 nieces (sister's birth children). She has been encarcerated for 15 months and got out in June 2007. During the last 2 1/2 years, she has sent NO financial support, has not seen the children except 2 times (at my initiation) and calls on average of every 4 months. My husband and I want to adopt the two children (we now are residents of Florida) and my sister has petitioned the court in Indiana for dissolution of the Guardianship. My question is this: What criteria does a birth parent have to meet in order to get this guardianship dissolved and what constitutes abandonment in Indiana to severe her parental rights?
