I have full physical custody of my 2 1/2 year old daughter. My ex has visitation rights. And we share joint legal custody Recently he asked me to split her time with us 50/50. Im not going to go into all of it but there are several reasons I dont feel this is best for my little girl. Basically, he doesnt pay his child support, only shows up half of the time he says hes going to (I have never kept her from him), shares a room with him and his wife at his dads house, and completely ignores my instructions (i.e potty training, sippy cup weening etc...). He says im taking away his legal rights to having her half of the time. Is this true? Or am I within my rights? I dont want to keep her from her dad completely. I just think its better for her to be here where she has her own space and some structure as much as possible. In California...
