Financial infidelity — the act of hiding money, debt or secret accounts from a partner — is increasingly acknowledged by lawyers as potentially more damaging than a physical affair. A Sydney-based family lawyer, Cassandra Kalpaxis, says victims often uncover a pattern of secrecy that can upend relationships and complicate separations.
New Zealand-born Amanda and Jared spent nearly a decade together before Amanda discovered Jared’s financial betrayal. Amanda described him as someone who was “terrible with money” while she saved, and she said they could not afford shared holidays because his spending outpaced the couple’s resources. They lived together, split rent and bills, and maintained a joint bank account until the savings were quietly drained. Amanda recalled Jared’s remarks about keeping money in trusts, and she learned only later that his family’s wealth and his own debts had been managed behind her back. A former bank visit revealed the balance had fallen to almost nothing, and Amanda said she had to top up the account while he spent freely.
Kalpaxis has described a broader pattern she has encountered in divorce cases: couples are often blindsided by hidden assets and a double life. In one case she recounted, a client learned her husband had been supporting a child overseas for ten years while running a remote business; after pushing for financial transparency, unusual transactions linked to overseas schools emerged, confirming the existence of another family abroad. The truth surfaced during separation, leaving families to explain to children that the life they trusted was built on lies. Kalpaxis stressed that such scenarios are not isolated, and she has worked with multiple clients who faced similar revelations over time.
The key red flags, she says, include resistance to providing documentation or access to bank statements, refusal to share passwords or statements, hostility when finances are discussed, distraction through lavish gifts, living beyond means while claiming hardship, signing documents without review, making large purchases or selling assets without consultation, and being secretive about business dealings or offshore accounts. Cryptocurrency and offshore accounts are also common concealment methods that can be difficult to locate. Kalpaxis notes that such indicators can creep in gradually, and she urges ongoing scrutiny when a partner controls access to shared financial information.
New research corroborates the concern that money secrecy is widespread. In a survey of more than 1,000 Australians, about 47.1% admitted to lying about money — including salary, savings and spending habits. Generational trends show Gen Z as the most likely cohort to lie about money (about 74.2%), followed by Millennials (56.2%), Gen X (41.2%), and Baby Boomers (22.1%). The findings underscore that financial deception can cross age groups and affect relationships across cultures, not just in high-profile cases.
Kalpaxis emphasizes that financial infidelity can be rooted in long-standing patterns of secrecy, control, and distrust, and it can emerge even when partners are ostensibly sharing expenses. She cautions that couples should seek transparency and address financial accounts collectively, particularly where assets are held in trusts, overseas entities, or unfamiliar investment vehicles. The stories highlighted in Daily Mail coverage — from Amanda and Jared’s decade-long dynamic to the overseas child revelation — illustrate the emotional and practical toll of financial deceit, and the importance of proactive financial planning in relationships.
