Please realize that you are NOT on track for full custody. You very well may be on track for primary custody, but your ex would practically have to be an axe murderer not to receive joint legal custody (joint decision making) these days.
Not necessarily. And not to pick on you specifically, this is one of those blanket statements that I hate.
Not all states have a presumption of joint legal custody. And of those that do, many have provisions that the presumption can be overcome, simply by showing that the parents cannot or will not communicate. Or that the parents frequently disagree.
Yet, we indicate all the time that joint is a given barring unfitness of a parent, and if someone posts that the other parent has sole legal, we assume that they MUST be hiding something that helped the judge determine their unfitness.
