What is the name of your state?
PA
Any extra advice or examples of custody evaluations anyone here has been through?
Who pays for the evaluation and what is the approx. cost?
I am the one requesting it Pro Se.
Thanks.
Also, how long can this process take?
You can check PA Family Law Code for the guidelines of a custody evaluation. I've learned much depends on who is doing it. A therapist, a psychologist, a GAL etc. etc.
I was apprehensive doing one since my nuttyX frequently has various agencies evaluate me for in ongoing campaign of harrassment- BUT it ended up being a positive thing for my case. Lots of personality disorders show up on those

In my state the length varies, mine took several months (though some of that time was due to various people taking vacations or scheduling conflicts etc.) We all underwent testing and had appointments alone and with our child. The reports are then given to the court and the judge reviews them. The judge will have the final say, but most times relies heavily on the evaluation/report.
It's wise, as someone advised above, to ask the court appoint someone or that both of you agree on someone- which eliminates the risk of feeling like one or the other of you have a "hired gun". The cost is usually paid by either the one requesting the evaluation or both parties depending on their ability to pay. (at least in my state)
Ours cost around $8,000 but we are in an expensive county of CA.
