Any recent change(s) in circumstances?
There is a legal process that likely your lawyer can explain more thoroughly than I can. The short explanation is that once a final decree is made then the court order - custody and parenting details - is considered the final one.
That is why our collective wisdom in peer support is that we more reasonably normal parents need to seek the best (or least bad) initial temp order and the same for the final decree's adjustments. The best for our children, which of course means the best for the reasonably normal parent. We still have to deal with the disordered parent but that's less of a priority.
But the other parent is still disordered. And no order works perfectly over time no matter how had we try. The way to make a subsequent change in the USA is to file for
Change of Circumstances. To make a major change of custody is a big deal, legally speaking. Basically it says that the existing order is unworkable, why you need a greater amount of legal authority in custody and/or the parenting schedule and solutions you propose to improve a new order.
In my case we had already made use of a child psychiatrist who was the evaluator in our
Custody Evaluation. For my
Change of Circumstances we used a
Guardian ad Litem, a child's advocate. Ours was a respected GAL, I was fortunate since some claiming to be GALs may be new lawyers inexperienced with resolving the parent/child relationships.
However, I noticed that my GAL and the judge tried to play both sides, so neither of us won but neither lost either. At the time we each had equal custody and equal parenting time. I had filed for custody as well as majority parenting time. Well, I gained custody (guardianship) but my ex didn't lose equal parenting time. The GAL explained it would allow ex to continue getting child support.
It still wasn't a fix but it was better. My authority, previously disrespected and obstructed, was a bit more clearly defined. A couple years later, after her disparagement and playing games with exchanges continued, I went back to court and got majority parenting schedule too.
