Postnuptial agreements, also known as post-marital agreements, are legal contracts between partners that define their rights and obligations made once the couple is married or living together defacto, in the event of a future divorce or separation. 

They are essentially “postnups” that are entered into during, rather than before, a marriage or defacto relationship. Think of it as a mid-marriage prenup.

Postnuptial agreements can be used to clarify financial and property arrangements, establish spousal support, and determine child custody and support.

What Should a Postnuptial Agreement Address?

Postnuptial agreements can address a variety of issues, including the division of property and debts, spousal support, and child custody and support. 

They can also specify how property acquired during the relationship will be divided, as well as the treatment of assets and debts acquired before the marriage / relationship. 

Additionally, postnuptial agreements can address issues such as inheritance and life insurance policies.

When to Enter into a Postnuptial Agreement

There are several situations in which a couple might choose to enter into a postnuptial agreement. 

For example, they may decide to do so after experiencing a significant change in their financial circumstances, such as a large inheritance or the start of a successful business. Couples may also choose to enter into a postnuptial agreement if they did not sign a prenuptial agreement before getting married, or if they want to revise or update a prenuptial agreement.

What Should a Postnuptial Agreement Include?

Post Nuptials are designed to address what would happen to assets and liabilities in the event of reasonably expected situations. 

Usually this would cover: 

  • Debts and liabilities
  • Asset
  • Income (including future income)
  • Inheritances
  • Wills 
  • Property division
  • Insurance
  • Superannuation
  • Businesses owned
  • Any other financial or real property asset.

A postnuptial agreement should include a clear and detailed description of the assets and debts that each spouse brings to the relationship, as well as any property that is acquired during the relationship.

It should also include provisions for the division of property and debts in the event of a divorce or separation, as well as the payment of spousal support and child support. Additionally, a postnuptial agreement should address any other issues that are important to the couple, such as the treatment of inheritance or the ownership of a business.

What Are the Pros and Cons of a Postnuptial Agreement?

The main advantage of a postnuptial agreement is that it can provide peace of mind and security for both spouses, as well as clarity about their financial and property arrangements. It can also help to avoid potentially costly and contentious litigation in the event of a divorce or separation. 

However, postnuptial agreements can be complex and difficult to negotiate, and may create tension in a relationship. 

Additionally, they may not be enforceable in all jurisdictions, and there is always the possibility that a court could override the terms of the agreement if it is deemed to be unfair or against public policy.


Why Enter into a Postnuptial Agreement?

A postnuptial agreement can provide a sense of security and clarity for both spouses, especially in situations where there is a significant disparity in income or assets. It can also help to avoid potentially costly and contentious litigation in the event of a divorce or separation.

Are Postnuptial Agreements Legally Binding?

Yes, postnuptial agreements are generally legally binding, as long as they meet certain requirements, such as being entered into voluntarily and with full disclosure of assets and liabilities. However, the enforceability of a postnuptial agreement may vary depending on the jurisdiction and the specific terms of the agreement.

What Is the Difference Between a Postnuptial Agreement and a Financial Agreement?

Nothing – they are essentially the same thing. A postnuptial agreement is a type of financial agreement that is entered into after the marriage (or defacto relationship) has taken place, while a financial agreement can be entered into before, during, or after a marriage or de facto relationship.
