Family dispute resolution is an opportunity for you and your former spouse to try and negotiate care arrangements for the child/ren amicably and without court intervention. If you agree about the care arrangements, you can create and sign a parenting plan, which is an agreement between the parties about those care arrangements, but is not enforceable at law. However, you can then apply to have the plan sealed by the court as consent orders, which makes it legally enforceable and the court can hold either party accountable should they contravene the orders.
Consider what the existing care arrangements are, what you would like them to be, and what concessions you are willing to make in order to reach an agreement. If the current arrangement is week-about, then that should continue. If the current arrangements are mostly with the other parent and alternate weekends with you, and you would like them to be 50/50, then you could consider a gradual increase in the time spent with arrangements to reach 50/50 in a few months time.
Have a few options open, but if there's anything sought that you don't agree with, don't sign the parenting plan. Wait and decide outside of the conference what your options are.
If you wish, you can have a legal representative present so they can ensure everything is legally square on your behalf. If you're unable to reach an agreement, then you may file for parenting orders through the court.
