My ex and I are most likely going to court for custody. I want sole custody and he wants joint legal. He is not fit. Anyway, his parents have custody over his 12 yr old. I am trying to find out if they have sole custody. Does anyone know how I can find their case? I looked on the court access website but I cannot find it on there?

Contact the public records division for the county where the custody order was established. You'll probably have to go there in person and search the files to find the case in question.
