Can you ask for a psychological evaluation during a divorce?
Yes, and evaluation can be part of the process (altho you'll probably have to pay for it). My atty asked me if I wanted it done by a psychologist or by a lawyer, and said I had a choice. I told him a psych (altho we withdrew the divorce action before it ever got to that).
I'm sure it varies from state to state, but that's how it worked here in FL.
