Here as far as visitation you need only comply with the current orders.Even if there has been deviation in the past, here as long as you comply you are fine.The real problem here is that the visitation no longer works,The child is older and needs non custodial parent to pitch in with activities.
If the other parent her take you back to court then it cuts both ways you have a chance to formalize the visitation.Again the orders control , the existing ones for now, any future ones when modified.
1. Do they have ground to stand on?Not if you are following existing orders here.
2. Concerns for child's social and extra curricular obligations as they age. Is child when with non custodial parent, despite being in agreement with enrolling child in such activities not expected to participate or uphold obligations?
I agree with you the no custodial parent has to shoulder their share of transportation here and participation during their visitation.
3. Grounds for full custody (currently primary physical custodial with joint legal custody)? Long history of disruptive behavior by noncustodial parent resulting in loss of child care, disrupted dr visit (the only one they attended), child endangerment x 2, and a laundry list of other false accusations made of custodial parent.
You only have to comply with existing orders.I understand you try to make deals and thats ok if the other side agrees otherwise you live and die by visitation orders.It may be time to return to court because child has aged and change is needed here since other parent will not cooperate.
I appreciate the chance to help you tonight.Thanks again and the best here.
