Cohabitation Property Agreement Template for Australia

A cohabitation property agreement is a legally binding contract that defines property rights, financial responsibilities, and asset division arrangements for unmarried couples living together in Australia. Under the Family Law Act 1975, de facto relationships have similar legal recognition to marriages, making this document essential for protecting your individual and shared interests throughout your relationship.

When do you need this document?

You should consider creating a cohabitation property agreement when moving in together, purchasing property jointly, or combining finances with your partner. This document becomes particularly important if you're bringing significant assets into the relationship, have children from previous relationships, or operate a business together. It's also valuable when one partner owns the family home and the other contributes to mortgage payments or improvements. Creating this agreement early in your cohabitation helps establish clear expectations and prevents misunderstandings about financial responsibilities and property ownership.

Key legal considerations

Your agreement must include comprehensive provisions for both separate and joint property, clearly defining what assets each partner owns individually and what will be considered shared property. Financial disclosure is mandatory—both parties must provide complete information about their assets, debts, and income. The document should address ongoing financial contributions, including mortgage payments, household expenses, and property improvements. It's crucial to include provisions for relationship breakdown, specifying how assets will be divided and whether either party has claims to property appreciation. Both parties must receive independent legal advice before signing to ensure the agreement is fair and enforceable under Australian law.

Legal requirements in Australia

Under the Family Law Act 1975 and various state Property Law Acts, cohabitation agreements must meet specific requirements to be legally binding. Both parties must enter the agreement voluntarily without duress or undue influence, and there must be full financial disclosure between partners. Independent legal representation is strongly recommended and often required for enforceability. The agreement must be in writing, signed by both parties, and witnessed according to state requirements. Some states may require registration of the agreement for certain property transactions. The document must comply with the Relationships Act in your state, which governs domestic relationship recognition and property rights for unmarried couples.
