I don’t have a recommendation for your jurisdiction but as someone with a TPO and going through a divorce, I have separate attorneys for my TPO and my divorce case. They are at the same firm and communicate freely. I think you need someone with a civil law focus, not family law focus, and they can then check in with your former divorce attorney so that a parenting plan can be modified as needed based on the outcome of the TPO.
I’m sorry you’re in this situation.
