My sister is 11 years old and has been in the foster care system for the last 5 years. I never even know I had a sister until her case manager called my mother and let her know. We live in Florida and I am 20 years old. Is there any way that I can legally adopt her?
It is legally possible to adopt your sister, but it would have to be approved by the state as she is in their custody. You should also remember that your sister may or may not want you to adopt her. She may be happy with, and attached to, the foster care family she has been placed with. The court is likely to consider her wishes, given that she is 11 years old.
The first step is to talk to your sister's case manager and explain that you are interested in adopting her. If they agree to consider allowing you to adopt your sister, you would have to be approved through a home study process that determines if your home is a safe emotional and physical space for your sister. The home study process includes a criminal background check and an analysis of your ability to financially support a child.
