My experience is/was in Oregon. Here, if the divorcing parents can’t agree voluntarily, the state hands down a parenting plan that divides the time 70/30, (which comes out to every-other-weekend, plus extra times during school vacation time), with the “residential parent” getting the 70%. “Residential parent” is the one who didn’t move out. Residential parent also gets legal custody (decision making power, remember, custody and parenting time can be different).
This is all assuming no criminal behavior, ie. abuse. If there’s no criminal behavior, and the parents can’t agree, then there is no arguing for more or less time, you just get the default plan. Again, all Oregon-specific info.
