I have custody of my 5 yr old since he was 1. The mother hasnt paid child support since Aug 2007.Between Aug 07 until July 08 she didnt visit the child,and called me approx. 7 times during that period she never asked to speak to the child, just to talk to me for a couple minutes. Recently she has been visiting the child often,since Sept 08. She has called me and told me that her newer husband has driven drunk with our son in the vehicle, and has also locked up her 8 year old son in his room to smoke marijuana,she told me this in Jan 09 when she had our son for visitaion and stated that her husband would be moving out.Now she states that they staying together and still living in the same house as where my son visits. Now she wants to change custody so he lives w/ her, what do I need to do.
