Thank you. On this website, I do not always get to give good news, and this is one of these times.
Someone in your situation is what is known as a third party when it comes to custody. Third parties who are not related to the child generally have no "standing" before the Court to demand custody (with Florida Department of Children and Families being an exception).
What can be done here is to get the authorities involved. If it did not work then, it may work now, especially if she is more willing to testify to the abuse. If the Florida Department of Children and Families takes custody of the child, then they can place the child with extended family or a foster home. This is where you come in. If you are licensed/registered as a foster family, the Florida Department of Children and Families may place the child with you. Especially if she and you request it and the Florida Department of Children and Families believes it is in the child's best interest.
However aside from that, there is no way to force a custody matter since you are unrelated to the child.
Please note: If I tell you simply what you wish to hear, this would be unfair to you. I need to be honest with you and sometimes this means providing information that is not optimal. Negative ratings are reserved for experts who are rude or for erroneous information. Please rate me on the quality of my information; do not punish me for my honesty.
I hope this helps and clarifies. Please use the SEND or REPLY button to keep chatting, or please RATE when finished. You may always ask follow ups at no charge after rating. Kindly rate my answer as one of TOP THREE FACES/STARS and then SUBMIT, as this is how experts get credit for our time. Rating my answer the bottom two faces/stars (or failing to submit the rating) does not give me credit and reflects poorly on me, even if my answer is correct. I work very hard to formulate an informative and honest answer for you; please reciprocate my good faith with a positive rating.
