Tyler Waits Jr guardian ad litem

I am trying to help my single mother of 4 including me, all under the age of 18. She is going through a custody battle for my younger brother Tyler. She has recently been told she needs to get a (GAL) guardian ad litem. We are trying so hard to win this case. NO child deserves to live with a father who is abusive and an addict. Money is very tight of course being a single mother. She has raised all of us kids since day one with no help. Any thing can help! Thank you!
