Custody and Visitation Issues: How Do I Ask the Judge for a Evaluation of My Sons Dads Home

My question involves a child custody case from the State of: Indiana

I have a custody case in May. I want to ask the judge for a mental evaluation on my sons dad and also a evaluation of his home. How would I go about asking for that to be done? Would I just suggest that he do one? Or would the judge do one anyways because its a custody case?
