Custody Evaluator

I lied. Apparently NY has minimal guidelines which custody evaluators are supposed to follow (thanks to reader M.L.). Overview here: NY State Education Dept.

Makes me wonder though, these could hardly be called directives, more like guidelines. Are there any repercussions for not following these guidelines? Seems as though it would be quite difficult to prove a step was skipped, for example.

Anyone from NY, report on your experience with a custody evaluation. Do you feel as though your evaluator addressed this list in its entirety?

Also, maybe all states have these, but they are all equally weak and therefore useless in type of practical sense.
