Common Law Partner Agreement Template for Australia

A Common Law Partner Agreement, also known as a cohabitation agreement, is a legal document that establishes clear financial and property arrangements between de facto partners in Australia. Under Australian law, particularly the Family Law Act 1975, de facto couples have significant legal rights similar to married couples, making this agreement essential for protecting your interests and avoiding disputes.

When do you need this document?

You should consider creating a Common Law Partner Agreement when you begin living together with your partner, before purchasing property together, or when either party brings significant assets into the relationship. This document is particularly valuable if you own a business, have children from previous relationships, or want to keep certain assets separate. It's also crucial if there's a significant income disparity between partners or if you're planning major financial commitments together. The agreement can be established at any point during your relationship, but it's most effective when created before major life changes or asset acquisitions.

Key legal considerations

Your agreement must address several critical areas to be legally sound and enforceable. Property division clauses should clearly distinguish between individual assets brought into the relationship and assets acquired together. Financial responsibility sections must outline how household expenses, debts, and income will be managed during the relationship and upon separation. The document should include dispute resolution mechanisms, specifying whether mediation or arbitration will be used before court proceedings. Child custody and support arrangements can be included if applicable, though these remain subject to the best interests of the child principle under Australian law. Additionally, the agreement should address inheritance rights and superannuation benefits, as de facto partners have automatic rights under succession laws that you may wish to modify.

Legal requirements in Australia

Under Australian law, your Common Law Partner Agreement must meet specific requirements to be enforceable. Both parties must receive independent legal advice before signing, and this must be documented with certificates from each party's lawyer. The agreement must be in writing and signed by both parties in the presence of witnesses. Full financial disclosure is mandatory – both partners must provide complete information about their assets, liabilities, and income. The agreement cannot be unconscionable or significantly unfair to either party. State-specific legislation, such as the Property (Relationships) Act in various states, may impose additional requirements. The document should comply with both federal family law and relevant state property law to ensure comprehensive protection and enforceability across all jurisdictions.
