This Hidden Cost of waiting: the impact that waiting can have on kids
Conflict gets most of the attention when we talk about harm to children of separation. But it is not the whole picture. Sometimes it is not conflict, or poor co-parenting, that creates harm, it is something far more passive and far more common: Leaving things unresolved and hoping they sort themselves out. In Parts 1 and 2 of this series, we looked at what the research tells us about children and separation, and what children actually need from their parents during this time. In this final piece, we need to talk about something that is harder to hear. But it is important.
Why Parents Wait
The reasons are completely understandable. Separation is exhausting. Emotions are raw. Formalising parenting arrangements feels like making the separation real. There is a hope that if things settle down naturally, there will not be any need for a formal process.
Sometimes that hope is right. Around 70% of separating Australian couples work out parenting arrangements between themselves without needing the family law system at all. That is genuinely the best outcome when it happens. Cooperative, flexible, child-focused arrangements reached without lawyers or courts.
But working it out between yourselves is very different from leaving things undefined and unresolved. Informal arrangements that exist in a state of ongoing uncertainty are not the same as cooperative agreements. And the research is clear about what prolonged uncertainty does to children.
What Uncertainty Actually Costs Children
When parenting arrangements are undefined, children live in a state of chronic low-level anxiety. Children in undefined arrangements often ask the same questions every day. Who is picking me up? How many sleeps until I see Mum? Am I going to Dad's this weekend? These are not curious questions; they are anxious ones. A child who has to ask is a child who does not know. And a child who does not know cannot settle.
Research consistently identifies this uncertainty, not the separation itself, as one of the most damaging things children experience during family breakdown. Children who know what to expect, who have a reliable routine across two households, and who can see that both parents have agreed on a plan, adjust significantly better than those left in limbo.
There is also a practical problem with delay. Informal arrangements calcify. What starts as a temporary arrangement while everyone figures things out gradually becomes the status quo. One parent becomes reluctant to change it. The other becomes frustrated. What could have been resolved cooperatively in one or two mediation sessions becomes entrenched and contested, and significantly more expensive and painful to unwind.
What the Law Now Says About This
The 2024 reforms to the Family Law Act actually enshrined this principle in legislation. The Act now expressly states that it is generally not in a child's best interests for legal disputes about them to go on indefinitely.
Courts must not reopen final parenting orders unless there has been a significant change in circumstances and it is in the child's best interests to reconsider. This change was specifically designed to reduce the pattern of ongoing litigation that keeps children trapped in uncertainty for years.
The message from both the law and the research is the same. Get to an agreement and get there as early as you can.
Mediation Is Not About Winning
One of the things that stops parents from seeking mediation is the belief that it is a negotiation. That someone wins and someone loses, and going in means giving something up. Good mediation is nothing like that. It is a facilitated conversation that starts not with positions ("I want the kids every weekend") but with interests: what does this child actually need? What does each parent need to be able to parent well? What arrangement will give the children the stability the research tells us they need?
When the conversation starts there, agreements are more durable, more flexible, and more satisfying for both parents. And most importantly, better for the children.
You Do Not Have to Have It All Figured Out
Many parents delay because they feel they need to know exactly what they want before starting the process. They do not. A single intake session with Resolve Well can help you understand what options look like, what the children's needs are pointing toward, and what a workable first framework might be. You do not need to arrive with all the answers. You just need to be willing to start the conversation.
The sooner children have a stable, agreed arrangement in place, the sooner they can begin to adjust. And the research is clear: they will adjust. Children are resilient. But resilience needs something stable to build on. Give them that, and you will have given them the most important thing you can during one of the hardest periods of their lives.
