A lot of issues here. If you are concerned with the child's safety, you could contact CYS and give them this information about your mother. It might inspire them to investigate a bit further. You can let them know that you are available to help raise and care for the child. As for custody, does your sister still have custody?
It sounds to me like you really need to consult with a local attorney experienced in family, including CYS, matters. I agree that you might try contacting CYS as my colleague has suggested. However, in addition, you should meet with an attorney. He or she may be able to help you navigate the treacherous CYS waters better than you are able to on your own. For several decades I've represented children and parents in CYS matters here in Delaware County, both as private counsel and as court-appointed, and know that sometimes it's hard even for the attorneys to get through all their protocols. You could really use some help.

This is not a simple question. Your sister certainly has the right to challenge this, which sounds like a voluntary agreement, not a court order. Whether you can do so independently is a more difficult question. As suggested, you can contact CYS as well as consult with a lawyer yourselfp
