Key takeaway: Separation means the end of a relationship, and it can happen even while living under one roof. The date of separation matters because it starts time limits for property and divorce. Practical priorities are securing finances, sorting interim arrangements for bills and the home, updating your will, and reaching agreement on parenting and property — ideally through mediation.
What does separation mean?
Separation is the point at which at least one partner decides the relationship is over and acts on that decision. There's no form to file to "become separated" — it happens in fact, not on paper. You can even be separated while still living in the same house, which is common for financial reasons or for the children's stability.
Just separated and not sure where to start? A consultation will help you map your next steps calmly.

Your date of separation is more than symbolic — it has legal consequences. It starts the 12-month clock you need before you can apply for divorce, and it begins the time limits for property settlement (two years from separation for de facto couples). It can also affect how contributions after separation are assessed, and the Australian Institute of Family Studies documents how common and significant this life transition is. Where the date is unclear — especially with separation under one roof — it's worth getting advice early. The Family Law Act 1975 governs how these timeframes apply.
First practical steps
- Secure your important documents — ID, financial records, tax returns, superannuation statements.
- Understand your finances — list assets, debts and accounts so you know the full picture.
- Think about the children — stability and routine matter most in the early days.
- Consider interim arrangements — who lives where, and how bills are covered, while things settle.
- Get early guidance — understanding your options prevents costly missteps. See our separation checklist →
Who pays the bills during separation?
There's no automatic rule, and this is a frequent flashpoint. In the interim, the sensible approach is to maintain the status quo where possible — keep paying joint commitments like the mortgage to protect both parties' credit and the asset itself — while you negotiate a fair arrangement. Where one partner controlled the finances, interim spousal maintenance may be appropriate. These interim questions are exactly the kind of thing mediation resolves quickly. See spousal maintenance →
Who stays in the house?
Neither partner is automatically required to leave the family home, and leaving doesn't mean giving up your claim to it. Who stays in the short term is often a practical decision — but if there's family violence, safety changes everything and protective orders can determine occupation. Mediation can help reach a workable interim arrangement without escalation. If safety is a concern, read this →

Many people search for a "separation agreement", expecting a single document that locks everything in. Australia works a little differently. A written agreement you reach between yourselves — sometimes called a separation agreement — is a useful record, but on its own it is generally not enforceable by a court. To make your arrangements binding, you formalise them through one of the recognised legal instruments below.
| Instrument | Covers | Legally binding? |
|---|---|---|
| Informal written agreement | Anything you both agree | No — a record only, but evidence of intent |
| Parenting plan | Children's living and time arrangements | No, but courts consider it |
| Consent orders | Property, finances and/or parenting | Yes — approved by the court |
| Binding financial agreement (BFA) | Property and finances | Yes — with independent legal advice for each party |
For most separating couples, the practical path is to reach agreement through mediation, then formalise the financial side as FCFCOA consent orders and the parenting side as a parenting plan or consent orders. That gives you certainty without a court fight. See how consent orders work →
Protecting yourself
- Update your will — separation doesn't automatically revoke gifts to an ex in every state; review it promptly.
- Review beneficiary nominations on superannuation and insurance.
- Protect your privacy — change passwords and secure your personal accounts.
- Keep records — of finances and important communications.
- Look after your wellbeing — lean on support, including counselling.
What comes next
Once the immediate practicalities are stable, the substantive questions — dividing property and finalising parenting — come into focus. For the vast majority of people, mediation is the fastest, least costly and least damaging way to resolve them. See property settlement after separation →
