It is one of the most common questions in a first appointment, and the anxiety behind it is usually financial. People assume they have to move out before anything can begin, and that moving out is unaffordable.
The reassuring answer is that the law has anticipated this. Separation is about the ending of the relationship, not the ending of the lease.
What the law actually says
The Family Law Act expressly contemplates couples who separate without one of them leaving. Section 49(2) provides that parties to a marriage may be held to have separated even though they continued to live in the same residence.
There is a related point in section 49(1) that often reassures people. The parties may be held to have separated even where the cohabitation was brought to an end by the action or conduct of only one of them. Separation does not require agreement, and one person can bring the relationship to an end.
The Federal Circuit and Family Court of Australia publishes a fact sheet dealing specifically with being separated but living under one roof, which is a useful indication of how routinely this arises.
Why the twelve months matters
Time spent separated under one roof counts towards that twelve month period. So the clock is not paused simply because you are still sharing a house.
What the court looks for
Because there is no change of address to point to, the Court looks at whether the marriage has genuinely ended in substance. No single factor decides it, and the Court considers the overall picture.
| Area | What tends to be relevant |
|---|---|
| Sleeping arrangements | Whether you share a bedroom, and when that changed |
| Finances | Separate accounts, who pays what, ending joint arrangements |
| Household tasks | Whether you still cook, clean and shop for each other |
| Social presentation | Whether family and friends know you have separated |
| Shared activities | Whether you still attend events together as a couple |
| Government agencies | Whether you have notified Centrelink, Medicare and others |
| Intention | Whether at least one of you formed and acted on the intention to end it |
Continuing to share a household for practical reasons does not undermine separation. Parents often keep cooking family meals because of the children, and that is entirely consistent with being separated. The question is whether the relationship as a couple has ended, not whether the household has.
The evidence requirement
This is the practical difference, and the thing worth preparing for early.
When you apply for a divorce and you have been separated under one roof for all or part of the twelve months, you will generally need to file additional affidavit evidence explaining the arrangement. That usually means an affidavit from you, and often a corroborating affidavit from somebody independent who can confirm what they observed.
A corroborating affidavit commonly comes from a family member, a close friend, a neighbour or another adult in the household. It is not a character reference. It should set out what that person actually saw and was told, and when.
Keep a quiet, factual record
Not for conflict, and not something the other person needs to be confronted with. Simply a record that supports what you will later need to establish.
- The date of separation and the conversation around it. Who said what, and when.
- Changes to sleeping arrangements. Including the date they changed.
- Separation of finances. Closing joint accounts, redirecting salary, splitting bills.
- Notifications to agencies. Centrelink and Medicare records are objective and dated.
- Who you told and when. The people who might later provide a corroborating affidavit.
- Changes in household routine. Laundry, meals, shopping done separately.
Keep it somewhere private and secure, and keep it factual rather than emotional. A dated, matter-of-fact note is far more persuasive than a recollection assembled under pressure.
What separation triggers beyond divorce
Divorce is only one consequence, and often not the most urgent one.
Separation starts the clock on property matters. Limitation periods apply to most financial and property proceedings, and for married couples an application for property adjustment must generally be made within twelve months of a divorce becoming final.
Importantly, you do not have to wait for a divorce to sort out property. Property settlement and parenting arrangements can be dealt with from the point of separation, and in most cases they should be. Our pages on separation and property settlements set out how those run in practice.
Separation also sharpens your disclosure obligations, which begin earlier than most people expect. Our page on financial disclosure explains what is required.
When staying is not the right call
Everything above assumes the arrangement is safe. Where it is not, the analysis changes entirely.
If there is family violence, including behaviour that is controlling or intimidating rather than physical, remaining in the home to preserve a tidy legal position is the wrong priority. Safety comes first, and leaving does not weaken your property or parenting position.
The Australian Government’s family relationships service provides information on separation and divorce, including where to find support. If you are in immediate danger, contact police on triple zero.
Making it workable
If you do stay, a few things reduce friction considerably.
Agree who pays what, in writing, even informally. Divide the physical space as far as the house allows. Agree how you will each spend time with the children and who is responsible for what. Set some basic expectations about guests, privacy and communication.
And set a review point, because most people underestimate how long they will be in this arrangement. A conversation at the three month mark about whether it is still working is far better than drifting.

This is general information rather than legal advice, and your circumstances will drive the answer. If you are separated or considering it, and you are still sharing a home, speak with us early. Getting the record right at the start is far easier than reconstructing it later.
