New partner after separation and your kids

Is dating before divorce allowed?

Yes. Australia has no-fault divorce, so the only ground is that the marriage has broken down irretrievably, shown by 12 months' separation. Starting a new relationship during that period is not unlawful and does not, by itself, affect the divorce. See the Federal Circuit and Family Court of Australia for the divorce process and our guide on how to get a divorce in Australia.

Where it matters is practical. A new relationship can complicate how you describe the date of separation, how finances are shared, and how the children and your ex react.

Effect on property settlement

Property is divided based on the contributions of each partner, future needs and what is just and equitable, under the Family Law Act 1975. The question is not who left or who met someone new, and the court generally does not penalise either party for the breakdown of the marriage.

Some points to watch:

• Spending on a new partner: money spent on a new partner from the pool, such as gifts, holidays or paying their debts, may be treated as wasted or added back.
• Contributions after separation: a new partner's contributions generally do not form part of your pool, but your financial circumstances may be considered under future needs.
• Time limits: there are strict limits for applying to court after divorce or separation, so do not delay property negotiations. See delaying property settlement.

Effect on child support

Child support is calculated from each parent's income and the care each provides, not from the new partner's income. However, a new partner can still affect arrangements indirectly. If your care percentage changes, or a new baby is born, the assessment can be updated. Parents can agree to a private arrangement or use the Services Australia — Child Support formula assessment.

See our child support guide for how assessments work. A new partner's income is generally not counted, but a parent's ability to earn and their living costs can matter in limited situations.

Introducing a new partner to the children

This is often the most sensitive part. There is no legal rule about when to introduce a new partner, but children generally cope best when changes are gradual. The Australian Institute of Family Studies highlights the importance of stable routines and low conflict between parents for children's wellbeing.

1. Wait until the relationship is established before introducing a partner as part of the children's lives.
2. Tell the other parent first, briefly and respectfully, so it does not come as a shock via the children.
3. Start with short, low-key meetings, not big occasions.
4. Keep parenting roles clear. A new partner supports; they do not replace a parent.
5. Do not ask children to keep secrets from the other parent.

Our guide to stepparent rights explains how a new partner's role is viewed in law.

Moving in together

Living with a new partner can have financial consequences, and it is worth thinking before acting. Moving in may affect government payments and living costs, and it can start a de facto relationship in law after the relevant period or in particular circumstances such as a child of the relationship or significant contributions. See de facto relationships.

If you are receiving spousal maintenance, a new de facto relationship or marriage can affect it. See spousal maintenance. If you have unfinished property matters, protecting the pool before combining finances is sensible. Check the information at MoneySmart (ASIC) on joint finances.

Common disputes and how to avoid them

• "Not around my kids": one parent objects to the other's partner. Courts rarely control who a parent dates unless there is a real risk to the child.
• Discipline and parenting roles: disagreement over what a new partner may do. Agree the boundaries in writing.
• Social media and gossip: avoid posting about the separation or the new partner, and avoid negative comments about your ex.
• Money: disputes over who pays for what when the pool is not yet settled.

Court is a blunt tool for these issues and rarely the best place to start. If there has been family violence or abuse, safety must come first. Call 000 in an emergency or contact 1800RESPECT on 1800 737 732 (1800RESPECT), and see domestic violence and family law.

How mediation helps

A new partner can bring out strong feelings, even when the separation was amicable. Mediation provides a neutral space to agree on introductions, parenting roles and communication, and to settle property and support so that new relationships do not cloud the old ones. Agreements can be recorded in a parenting plan or formalised through consent orders.

Family lawyers and mediators work well together, and we encourage you to have your lawyer review any final agreement. Explore our co-parenting mediation service for more.
