Protect Bradly

My daughter, who is now 20 years old,  is my world. She met a man and thought she was in love. They got married and she got pregnant. Then his true colors came out. He  held a knife to her throat at one point. He verbally and mentally abused her. He neglected their son and he even broke their dog's leg. He has a temper that can't be controlled and does and says what he wants. She thankfully left him about 6 months ago and never looked back. She has filed for full custody of my grandson and we have a court date on December 4th. I am asking you all for help.  I can't afford to pay the attorney costs for my daughter. If I could I would in a heart beat. I am asking for the retainer cost for the lawyer which is $600.  If I can pay all the attorney costs for her it would be great to.  My grandson is only 8 months old and an absolutely adorable. Thank you for anything that you can give me to help her!!!
