What is a postnuptial agreement?
A postnuptial agreement (or "postnup") is a legally binding agreement made after a couple is already married or in a de facto relationship. It outlines how property, finances, debts, and other assets will be divided if the relationship ends in separation or divorce.
In Australia, postnups are a form of Binding Financial Agreement (BFA) under the Family Law Act 1975. Like prenuptial agreements, they must meet strict legal requirements including independent legal advice for both parties to be valid and enforceable. Think of it as creating financial clarity and protection after you've already said "I do". It provides certainty and can prevent costly disputes later.
Key benefits of postnuptial agreements
A well-drafted postnup can protect personal, family, or business assets acquired during the marriage while helping reduce conflict by setting clear expectations. It can help you avoid costly court disputes if separation occurs and protect one partner from the other's debts.
You can also clarify ownership of gifts, inheritances, or future earnings and help rebuild trust or stability in a strained relationship. Many couples find that creating a postnup actually strengthens their marriage by encouraging honest conversations about finances and future goals.
