I really doubt that it was going to be all that simple. With custody, it may start with an interim agreement for scheduled visitation, but it usually doesn't take long for an application to be made to modify that agreement ... the psych eval is usually the first tactic. The party that wants custody will take notes at every visit, documenting everything that can be interpretted as detrimental to the child. For example, a scrape on the knee can be interpretted as negligent parenting. If it was all that simple, custody wouldn't be such an expensive, protracted, antagonistic process.
In the long run - yes but in the short term - it was visitation and he JY set it up for the full blown custody because he would not agree in writing to a visitation schedule.
