My question involves guardianship in the State of: Indiana and Colorado.
My younger sisters were put into foster care once my mom went to jail when they were 3 and 1 1/2, this was in Indiana. My grandmother came from Colorado to take care of them and raise them. My mother has wanted nothing to do with them, my other siblings, or myself since than 14yrs ago. 7 years ago my grandmother died and my aunt has been taking care of them since then. My younger brother (24, married, with a 3yr old) and myself (25 with a 4yr-old) and my older brother (26) have been informed that there living situation isn't good. They are still with my aunt and her daughter (now 19). My younger cousin treats them horribly and my aunt does nothing about it (verbally and mentally abusing them). Their house is infested with bedbugs, and other bugs. As of right now me and my younger brother want to get custody of them (we live in Indiana). We are unsure if they are wards of the state of Indiana, as custody was never established when my grandmother came to get them. We have asked my aunt if it was ok for us to have them and she has flat out refused it to happen. What do we need to do to get them?
