If you have been told that "co-parenting" is the goal after separation, but the reality of communicating with your former partner makes that goal feel impossible, you have not failed. You may simply be in a situation where the right structure is parallel parenting — and that is a legitimate, well-established approach with its own evidence base.

This guide explains the distinction between the two, when each one fits, and how to move from one to the other if needed. I built It's In Writing for separated parents in both modes — the platform's "messaging only, no shared calendars or expense trackers" design fits parallel parenting particularly well, but it works for co-parenting too.

The two models

Co-parenting

Co-parenting is what most separation guidance assumes. Two parents, in two households, raising the children as a coordinated team. Joint decisions on major matters. Open communication channels for minor matters. Some flexibility around schedules. Sometimes shared events (birthdays, school plays, graduations).

Co-parenting requires:

  • A baseline of mutual respect, even after separation.
  • Communication that does not consistently escalate.
  • The ability to disagree and resolve disagreements.
  • Both parents reasonably able to put the children's interests above their own grievances.

Where these conditions exist, co-parenting is generally the better outcome for children — it gives them coordinated support across two households.

Parallel parenting

Parallel parenting is the alternative when co-parenting is not viable. The two households operate independently. Each parent makes their own day-to-day decisions. Communication is restricted to logistics — pickups, schedules, essential information about the children. Minor disagreements are not negotiated; each parent handles their own household their way.

Parallel parenting suits:

  • High-conflict separations where attempted communication consistently escalates.
  • Situations involving past or ongoing emotional pressure that makes equal-footing communication difficult.
  • Cases where personality patterns (on either side) make collaborative decision-making unworkable.
  • The aftermath of a particularly difficult separation, often as a temporary structure that may eventually relax into more cooperative co-parenting once tempers settle.

Parallel parenting is not a sign of failure. It is a recognition that the children are better served by two functional households operating in parallel than by ongoing parental conflict in a forced-cooperation model.

How they look in practice

A small comparison table:

Issue Co-parenting approach Parallel parenting approach
Daily communication Open, friendly, regular Logistics only, written, brief
Pickup/dropoff Casual handovers, brief chat Curbside drop, no conversation
School events Both parents attend One attends each, no overlap
Birthday parties Joint or coordinated Two separate celebrations
Sick child decisions Phoned through, joint discussion Each parent handles in their own time
Discipline approach Coordinated rules across houses Each household sets own rules
Major decisions (school, medical) Joint, by consensus Joint by parenting plan, in writing
Schedule changes Flexible, by request Strict adherence to written plan
Information sharing Casual, ongoing Formal, channel-restricted
Disagreement resolution Direct discussion Through mediator or legal process

Different situations need different rows from each column. There is no rule that you must be all-in on one mode.

Mixed approaches

Most real-world separations are a mixture. You might:

  • Co-parent major decisions, parallel-parent daily life. Joint decisions on school enrolment, medical procedures, religious observance. Independent decisions on bedtimes, screen time, household rules.
  • Co-parent during stable periods, parallel-parent during friction. When communication is going well, more cooperation. When friction rises, retreat to logistics-only mode.
  • Co-parent for one child, parallel-parent for another. Different children sometimes need different arrangements, particularly if one parent has a stronger relationship with one child.
  • Start parallel and move toward co-parenting over years. This is common. The first 12–24 months after separation often need parallel discipline; later years may relax as the situation stabilises.

The right structure is whichever one actually serves your children's stability. The label matters less than the substance.

When to choose parallel parenting

Concrete signals that parallel parenting is the right structure:

  • Communication consistently escalates. Every attempt at discussion turns into argument. The children pick up on it.
  • Past or ongoing power-imbalance dynamics make equal-footing communication unworkable. This includes situations where one party has a pattern of using communication channels for harassment or control.
  • Joint decisions are repeatedly used as leverage. If discussions about pickup times or school events become opportunities for grievance airing, the joint-decision frame is not serving the decisions.
  • The children show distress around parental contact. Children are usually better at reading the room than adults give them credit for. Visible distress at handovers is a signal.
  • Either parent's mental health is being damaged by the communication pattern. Sustained drain on a parent's wellbeing eventually affects parenting capacity.
  • You have tried co-parenting in good faith and it has not worked. Repeated failure is a finding, not a moral judgment.

If two or three of these apply to your situation, parallel parenting is worth seriously considering.

How to move from co-parenting to parallel parenting

The shift is usually gradual. Practical steps:

Reduce communication to logistics

Stop responding to messages that are not about logistics. If a message contains discussion or argument that does not require a logistical response, do not engage. Use the BIFF method for any reply that is required.

Move all communication to written channels

Phone calls and in-person discussions create flexibility for the wrong reasons — they are also harder to document. Move everything to a written platform. We have a guide on documenting co-parent communication for court that covers this.

Make decisions within your household

Stop seeking input on minor decisions. Bedtimes, screen time, household rules, day-to-day routines — these are yours to set in your house. The other parent does the same in their house. Children adapt to two different sets of rules more easily than they adapt to ongoing conflict between parents.

Update the parenting plan

If you have a written parenting plan or court order, consider updating it to reflect the new structure. A formal plan that specifies:

  • Communication channels (e.g. "all communication via [app] only")
  • Decision-making authority (e.g. "minor day-to-day decisions are within the residential parent's authority")
  • Schedule with minimal change-by-agreement clauses
  • A defined dispute-resolution process for major decisions

…provides clarity that prevents the structure from drifting back to attempted co-parenting in moments of weakness.

Consider mediation or court orders

If informal restructuring is not working — particularly if the other parent does not respect the reduced-communication boundaries — formal mediation or consent orders can lock the structure in place. Family Dispute Resolution (FDR) is required before most family-court applications and can sometimes be a useful intermediate step.

What about the children?

Most parents considering parallel parenting worry that it will be harder on the children. Research suggests the opposite for high-conflict situations: children of parallel-parented separations generally do better than children of attempted-co-parenting-that-fails separations, because the visible conflict is reduced.

Practical tips for the children:

  • Don't disparage the other household. Two-household differences are normal. Different rules at each parent's house is not a problem unless one parent makes it one.
  • Be predictable in your own household. Children adapt to differences between households more easily when each household is internally consistent.
  • Don't make the children messengers. Communication between parents goes through written channels, not via the children. "Tell your father…" is not a parenting plan.
  • Don't pump them for information about the other household. What happens at the other parent's house is mostly not your business unless safety is involved.

A note on terminology

Australian family law does not use the phrase "parallel parenting" in legislation. The Family Law Act 1975 (Cth) and the FCFCOA Rules 2021 use language like "parental responsibility", "parenting arrangements", and "the child spends time with". The substance of parallel parenting can be implemented through these legal frames — the term is descriptive, not legal.

When talking to a lawyer, mediator, or court, describe the structure (limited communication channels, household-level decision-making authority, structured schedule with defined exception process). The professional vocabulary will follow.

Try It's In Writing

If parallel parenting is the right structure for your situation, the platform that produces the cleanest documented logistics-only record is It's In Writing. Start free — five messages on signup, no card required. Reading is always free for the parent you invite.

The structure is not failure. It is recognition. The children are better served by two stable households than by one performance of cooperation that everyone is exhausted by.
