Separating from a spouse or de facto partner often involves complex decisions about how property Is divided. In addition to family law considerations under the Family Law Act 1975 (Cth), separating couples must navigate state‑based tax regimes, particularly transfer duty (stamp duty) and, in some cases, land tax. Failing to properly address these obligations can lead to unexpected and avoidable costs. With the right structuring and advice, many of these costs can be reduced or eliminated.
