A Postnuptial Agreement is a legal document created by two individuals who are already married, outlining the division of assets and liabilities in the event of a divorce or separation. Like prenuptial agreements, postnuptial agreements can be used to protect individual assets, clarify financial expectations, and potentially minimise conflicts in the event of a divorce or separation.

Postnuptial agreements typically include provisions for the division of property, spousal support, and other financial arrangements. They may also address other issues, such as child custody and visitation. In order for a postnuptial agreement to be legally binding, it must be signed by both parties and can be used to modify or replace an existing prenuptial agreement.

Postnuptial agreements are often used by couples who did not sign a prenuptial agreement before marriage but still wish to clarify their financial rights and obligations in the event of a divorce. They can also be used to update an existing prenuptial agreement to reflect changes in financial circumstances, such as the acquisition of new assets or a change in career.
