In parenting matters, the Federal Circuit and Family Court of Australia always maintains the best interests of the child.

Your new relationship could become relevant if:

• Your child will be spending time with or living with your new partner
• Your new partner has a history of violence, abuse, or criminal behaviour
• There are concerns about how the relationship might affect your child’s emotional wellbeing or safety

If your new partner plays a significant role in your child’s life, the court may want to know about them. For example, if they are helping to raise the child or are frequently present during parenting time, their influence could be examined. If you fail to disclose a new relationship and the court later learns about it, especially if the partner poses a potential risk to the child, it may affect your credibility and weaken your case.

In property settlements, a new relationship may impact how the court assesses your financial circumstances.

Factors that may be considered include:

• Whether you’ve entered a de facto relationship with your new partner
• Whether your new partner contributes to household expenses
• Whether you have joint assets or financial resources
• Whether your new relationship affects your need for spousal maintenance

The court may find that your financial needs are lower if you are now supported by a new partner, which can influence how property and assets are divided.

Under Australian family law, both parties must provide full and frank disclosure throughout the legal process.

This includes:

• Your income, assets, liabilities, and superannuation
• Any financial resources, including support from a new partner
• Any change in personal circumstances, such as living arrangements or new relationships

If your new partner is contributing financially to your life, this must usually be disclosed during property negotiations or court proceedings.

You are not legally required to volunteer personal details to your ex-partner outside of court unless they are relevant to your case. However, if your new relationship affects parenting or finances, then it becomes legally significant and should be disclosed as part of your legal obligations.

Disclosing a new relationship may seem personal, but in family law, it can carry serious legal consequences. If you’re unsure about what to disclose, it’s best to get advice from a qualified family lawyer.
