Do I have to disclose my new partner’s assets during a divorce?

22 December 2025

When a relationship ends with your ex-partner and you eventually begin to see somebody else, the question of your new partner’s assets can become surprisingly complex. In family law matters, especially involving property settlements, the court does not automatically require full disclosure of a new partner’s financial situation.

However, certain details can be relevant when determining a fair property settlement or other asset separation. This is particularly important in cases involving a de facto relationship, where the living arrangements and contributions of a new partner may influence the property settlement process. Understanding your legal obligations and the limits of what must be disclosed is essential for protecting your interests.

New partner, new finances. What does the court need to know?

How much does the Court need to know about your new partner following a divorce, and will their personal financial circumstances impact the property settlement with your ex? The short answer is generally, no. But you need to be clear as to what may be required.

You won’t need to provide full disclosure of your new partner’s financial circumstances. However, there is information the court will need to know:

What the family court requires in a Financial Statement

Anyone involved in family law property proceedings needs to file and serve what is called a Financial Statement, which includes information about other members of the household, such as name, age, relationship, and average weekly income.

Disclosure of your new partner’s contributions and expenses

If you’re living with a new partner, that information will need to be included in the Financial Statement. You also have to disclose all the expenses you’re paying for your new partner, and everything your new partner is paying for you.

How shared living expenses affect future financial needs

If your new partner is contributing towards living expenses, for example paying half the rent, then the Court may consider that your future financial needs will be less than your former spouse’s needs. You receive the benefit of having your expenses shared or paid by someone else. If you are helping to support a new partner or children, you will need to show the court evidence of that financial support.

Why the court asks for this financial disclosure information

Even though there is no general obligation to reveal every detail of a new partner’s financial circumstances relating to property matters, the court still needs certain information to ensure fairness. This includes details about a party cohabitating and contributing to household expenses, which can influence the division of the property pool.

Courts in Australia operate under the Family Law Act 1975, which requires parties to make a frank financial disclosure of their own financial resources and any relevant information affecting the case. This includes circumstances where a new de facto partner may be supporting you or sharing living arrangements. Understanding why the court requires this information helps to clarify your legal obligations and prepares you for the property settlement process.

Case Example: How the Court Considers Disclosure of a New Partner’s Financial Circumstances

In a recent case, the Court found there was no general obligation for a party to provide full and frank disclosure of their domestic partner’s financial circumstances.In this case, there was a long delay between the couple’s separation and the final property settlement, during which time the husband had remarried.

The husband married his new wife about two years before the trial started. They had two children together, who were aged four years and two years at the time of trial.

The husband gave no evidence about his new wife’s financial circumstances, and he did not call her as a witness. On appeal, the ex-wife said the trial judge mistakenly overlooked a contribution made by her, by failing to take into account that she allowed the husband and his new partner to live in one of their jointly owned properties, during which time the husband reduced the amount of the mortgage repayments.

The husband said his current wife did not work and he supported both her and their two young children. The ex-wife argued that the husband’s “lack of transparency and disclosure” about his current wife’s “financial position” should cause the court “considerable disquiet”.

However, the court found that “save for the provision of information about the income of other members of the parties’ households and any expenses paid on their behalf by third parties, disclosed in their prescribed Financial Statements, there is no general obligation upon parties to disclose the financial circumstances of their domestic partners”.

Legal obligations and exceptions in Family Law

Under the Family Law Act 1975, disclosure requirements are a critical part of ensuring a fair property settlement. There is a general obligation to make a full disclosure of relevant financial information. However, this obligation typically applies to your own finances, with only limited disclosure of your new partner’s situation.

When you are in a de facto relationship, certain relevant documents, such as bank statements and evidence of household expenses, may be required to support your case. This ensures transparency and allows the court to assess whether the living arrangements and contributions of a new de facto partner should be considered in property matters.

There are some exceptions, for example, in the case of a binding financial agreement or a consent order, disclosure requirements may differ. Knowing your legal obligations and understanding when exceptions apply is vital.

Can my ex claim money from my new partner in Australia?

It’s a common worry after separation: can my ex claim money from my new partner? In Australia, the law is clear: your new partner is generally protected from such claims by your former partner. That said, the court may still look at your living arrangements, each party’s financial circumstances, and whether your new partner contributes to your living expenses when deciding a settlement. This can feel overwhelming, especially when you’re trying to move forward. Understanding your rights and what the law allows can help ease uncertainty and protect both your relationship and your peace of mind.

Risks of not disclosing financial resources

Failing to provide adequate information about living arrangements or not being transparent about a partner’s income or contributions can have significant consequences. The court may view this as a lack of frank financial disclosure and may impose penalties or adjust property orders accordingly.

In a family law dispute, withholding information can damage credibility and influence the judge’s assessment of the case. It could also result in prolonged court proceedings and increased costs for all parties involved. Ensuring compliance with disclosure requirements protects your interests and strengthens your position during the property settlement process.

It’s okay to move on, but be legally prepared

Ending a relationship is never easy, and starting a new one can bring feelings of uncertainty or even guilt. If you are moving in with a new partner before divorce, it’s important to remember that there is nothing to be ashamed of; life goes on. What matters most is protecting yourself and your future. While it’s natural to embrace a fresh start, being legally prepared will ensure your new relationship doesn’t become a source of unexpected complications later.
