I have a niece and a nephew. I had custody of them and let the grandmother have them because she had the oldest sister. Now I find out she is abuseing the children and the oldest who is 15 is pregrant. I want the kids back. What is the chances of getting them back? I live in Alabama ( the children are 8 , 10 , and the oldest 15

If you can prove abuse you stand a good chance.

What if the kids tell about the abuse and neglect?

That will be taken into consideration.
