My question involves child abuse or neglect in the State of: INDIANA
Hello I have a issue concerning my sister and her 2 children. My father called me today asking if he could bring my sister's 2 children ages 5 & 1 to stay at our house and take custody or watch them indefinitely until my sister can get clean and be around to take care of her own children. Basically my sister is addicted to pain killers and heroin and my dad informed me that she has not been around at all and she has failed to live up to her parental roles set forth by the CPS to keep custody of them. My dad basically told me he thinks its only a matter of days before CPS comes and takes the children who have been solely in his care for the past couple of months. No guardianships or custody has been signed over to my father or to me by my sister at all. He wants to bring them the 3 hours north to our house tomorrow.
I am concerned about if we can get into trouble for harboring these children without the mothers knowledge or consent. My dad said basically if something happens he will take sole responsibility for the consequences if there were any. I'm not sure this is comforting enough to me. I have to know exactly what the consequences would be for me if she decided to take action. Is this too big of a risk for me to take? I am just so concerned for these children and would hate to see my blood end up in some foster home. I would really appreciate any guidance or information regarding this as I feel lost in what to do. Thank you so much for your time.
If you need any further background on the situation or have questions just ask and I will try to respond asap.
