Deciding that a relationship is over is rarely simple, and it becomes even harder when the person you once shared your life with refuses to accept it. You may feel stuck, guilty for wanting to leave, or worried that nothing can happen until your partner agrees. Many people in this position quietly wonder whether they are even allowed to act on their own.
You are, and understanding why can lift a weight from your shoulders. In Australia, ending a relationship does not depend on your partner’s cooperation, and knowing how the law works lets you take concrete steps rather than waiting for an agreement that may never come.
Below, the team at Nevett Ford explains what separation actually requires, your options when only one person wants out, and the practical steps that protect you in the meantime.
Can My Partner Stop Me From Separating?
No, your partner cannot legally stop you from separating. Under the Family Law Act 1975, Australia operates a no-fault system, which means the court is not interested in who ended the relationship or why. Separation is not a joint decision that needs sign-off from both people. It happens when at least one person decides the relationship is finished and makes that decision clear to the other.
Your partner may deny that anything has changed or hold out hope that things will return to the way they were. Neither response stops the separation from being legally valid. Their cooperation can make the process smoother and less stressful, but it isn’t required, and you don’t need their permission to begin.
What Does Separation Actually Involve?
In practical terms, there’s no form to lodge and no register to notify. What matters is that your intention is clear and your day-to-day conduct reflects it.
Can we be separated while living together?
Many couples cannot move into separate homes straight away, often for financial reasons or to keep life stable for the children. You can still be separated while living at the same address. This is known as separation under one roof, and the court recognises it.
In these situations, you may need to show that you were leading separate lives. Evidence can include sleeping in different rooms, dividing finances, reducing shared activities, and telling close family or friends that the relationship has ended. Make a note of the date you separated, because that date carries legal weight later on.
Can I Get Divorced If My Partner Will Not Agree?
Yes. Divorce in Australia rests on a single ground: that the marriage has broken down irretrievably, shown by a period of separation of at least twelve months. An unwilling partner cannot change that.
Applying for divorce on your own
You are entitled to apply on your own through a sole application for divorce, filed in the Federal Circuit and Family Court of Australia. Your partner must be formally served so they are aware of the proceedings, but being served does not mean they have consented. They cannot block the divorce simply because they disagree with it. Provided the legal requirements are met, the court can grant it regardless of the parties’ wishes.
Divorce lawyers handle uncooperative partners all the time, and letting a divorce lawyer manage the filing and service spares you much of the stress. If your partner is avoiding service or refusing to cooperate with paperwork, a family divorce lawyer can talk you through the alternatives open to you.
What about property, finances, and the children?
Divorce is also a separate process from dividing property and arranging the care of the children. Ending the marriage doesn’t settle those questions on its own, and they can be dealt with on their own timeline.
Two financial matters often arise alongside a divorce: property settlement and spousal maintenance. Spousal maintenance is support that one person may have to pay to the other where that person cannot reasonably meet their own living costs. Time limits apply once a divorce is finalised, so it’s wise to obtain advice before they pass.
What if we were in a de facto relationship?
If you were in a de facto relationship rather than a marriage, the same principle holds: your partner cannot force the relationship to continue. There’s no divorce to apply for, since that step exists only for married couples. Still, you can generally seek a property settlement and spousal maintenance under the same Family Law Act, provided you meet the criteria for a de facto relationship. Parenting arrangements are decided in the same way, based on the children’s best interests rather than the parents’ relationship status.
What Steps Can I Take If My Partner Refuses to Separate?
Even when the separation is one-sided, you have options. A measured approach keeps tension low and gives you space to plan.
1. Communicate your decision clearly.
Tell your partner calmly and directly that things are over between you. Staying consistent avoids mixed messages and helps fix your separation date.
2. Set clear boundaries.
This might mean separate bedrooms, separate bank accounts, and limiting conversations to logistics. Boundaries aren’t a punishment. They simply let each of you adapt to a household that now runs on different terms.
3. Protect your finances
Take note of joint accounts, assets, and debts, and avoid making major financial decisions under pressure. Getting advice early gives you a clearer picture of your options.
4. Prioritise the children
If you have children, try to keep discussions centred on their needs. Parenting arrangements, also known as child custody, can usually be negotiated separately from the emotional issues between you and your partner.
5. Consider mediation
A neutral third party can help you settle parenting and property questions, even when your partner digs in at first.
6. Get family law advice early
Family law lawyers can clarify your rights and obligations from the outset and help you avoid costly missteps.
