Child Custody Lawyer

Hi my Name is Chad but this isn't about me it's about my two kids Harmony and Hunter. On 3/16/2015 I filed for a change of custody order to get custody of my children because my son said he was being abused by my ex wife's new husband. We went to mediation and the mediator did an interview with Hunter. She found out it was true and my ex wife knew about it. She was going to grant us custody. On the custody court date my ex wife made a false claim that I had sexually abused my 3 year old daughter. I go back to court on July 6 2015. This time I need to have a lawyer. I can't let her get away with beating my kids. I need this money so I can get a lawyer and bring these children back to a safe home. Where they can grow, live and play. She has mental and physically abused these children long enough. I need your help, please.
