What to consider before varying or terminating a legal agreement in Australia

Varying or terminating a legal agreement refers to formally changing (vary) or cancelling (terminate) an existing legal agreement under Australian family law. This applies to agreements like prenups and postnups (Binding Financial Agreements), cohabitation agreements, and separation agreements.

Under the Family Law Act 1975, these agreements must be varied or terminated through a new signed agreement that requires independent legal advice for both parties. You cannot simply ignore or informally change these agreements, as this may create legal complications and the original agreement may still be enforceable.

Key benefits of properly varying or terminating agreements

Keeping agreements up to date as life changes helps avoid legal risks from outdated or unfair terms. Whether you've had children, changed careers, inherited assets, or reconciled after separation, updating your agreements ensures they reflect your current reality.

Properly varying or terminating agreements reduces future conflict by ensuring both parties agree in writing to any changes. It prevents courts from setting aside informal changes and ensures enforceability through proper legal process. This gives both parties certainty about their legal position.
