High Conflict Custody Australia: Strategies for Difficult Co-Parenting Situations
When Co-Parenting Isn't Working
Some separations are amicable. Others are not. High-conflict custody situations — where one or both parents are combative, controlling, or unable to communicate without escalation — are among the most draining experiences in family law. And they're more common than people admit: family lawyers estimate that roughly 10–15% of separating families end up in protracted, high-conflict parenting disputes.
The May 2024 amendments to the Family Law Act 1975 removed the presumption of equal shared parental responsibility, which in high-conflict cases often became a weapon — parents demanding 50/50 time not because it served the child, but to control the other parent. The new framework evaluates each family on its facts, with safety as the first consideration. For genuinely high-conflict families, this is a better starting point.
Parallel Parenting vs Co-Parenting
Standard co-parenting advice assumes both parents can communicate, compromise, and coordinate. In high-conflict situations, that assumption is wrong. Every text message, email, or school-gate interaction becomes an opportunity for conflict.
Parallel parenting is the alternative. The core principle: each parent runs their household independently. They don't discuss daily routines, discipline approaches, or bedtime rules. Communication is limited to essential logistics — schedule changes, medical emergencies, school events — and happens exclusively in writing.
Key elements of a parallel parenting structure:
- Written communication only. No phone calls. Text or email, kept brief and factual. Some families use dedicated apps like OurFamilyWizard that create timestamped, uneditable records.
- Detailed orders. The more specific the parenting orders, the fewer decisions require discussion. "Parent A has the child every Wednesday and Thursday" eliminates the weekly negotiation that "reasonable time" invites.
- Neutral changeovers. School drop-off and pickup removes the need for direct parent-to-parent contact. If the child isn't school-age, a neutral third-party location (like a supervised contact centre) keeps exchanges safe.
- Independent decision-making for day-to-day matters. Each parent makes decisions about meals, homework, screen time, and discipline during their own parenting time without consulting the other.
Major long-term decisions (schooling, medical treatment, religious upbringing) are part of parental responsibility. A parenting order can allocate that decision-making, including to one parent; day-to-day decisions remain with each parent during their parenting time.
Protecting Your Position in Court
If you're headed to court in a high-conflict situation, your behaviour matters as much as your arguments. Judges see dozens of parents each week who claim the other parent is impossible. What separates credible claims from noise is evidence and proportionality.
Document, don't retaliate. When the other parent sends an aggressive message, don't match their tone. Reply factually or not at all. Save everything.
Follow orders exactly. Even if the other parent isn't complying, your compliance is what the court evaluates when you file a contravention application. If you retaliate by withholding the child, you've undercut your own case.
Use professional support. A family consultant, child psychologist, or counsellor can provide evidence about the child's wellbeing that carries weight with the court. Self-reported parental frustration does not.

When to Apply for Sole Parental Responsibility
In genuinely high-conflict cases — particularly where one parent's behaviour is harmful to the child — applying for sole parental responsibility may be appropriate. This gives one parent the authority to make major decisions about the child without needing the other's consent.
Courts grant sole parental responsibility when they're satisfied that joint decision-making is unworkable and that the conflict itself is harming the child. Evidence that strengthens an application:
- A documented history of the other parent refusing to engage in decision-making (ignoring school enrolment requests, refusing to consent to medical treatment)
- Evidence that communication attempts consistently escalate into abuse or threats
- Professional assessments showing the child is suffering from the parental conflict
Sole parental responsibility does not mean the other parent loses parenting time. They can still have regular contact — the order only affects decision-making authority.
