Is A Postnuptial Agreement Legally Binding?

If a postnuptial agreement (Binding Financial Agreement) correctly complies with the appropriate provisions of the Family Law Act 1975, the document will legally bind the signatories to the agreed procedure set out in the document.

Generally speaking a valid and legally binding agreement will contain the following elements:

  • The agreement must be voluntary. Neither party should feel pressured into entering into the agreement;
  • Both parties need to be separately and independently advised by a lawyer;
  • Both parties must disclose their financial assets and liabilities in a full, frank and honest manner;
  • There should be adequate time to reflect and consider the terms that are proposed in the postnuptial agreement, and neither party should feel pressured by time to sign the agreement;
  • The agreement must be fair or it is unlikely to be upheld. The parties also should recognise that the matrimonial circumstances and the agreement are likely to change as time goes by.

There are provisions with the Act that address Binding Financial Agreements involving fraud, impracticality, unenforceability, changes in circumstances, unconscionable conduct and superannuation concerns. Under the Act, Binding Financial Agreements involving any of these considerations may be set aside by a court.

As time passes it is also advised for postnuptial agreements to be reviewed, especially if either party’s financial or personal circumstances change.
