Legal Framework and Enforcement

Prenups are legally recognized under Section 90B of the Family Law Act 1975.

Amending and Setting Aside Prenups

Additionally, couples can mutually agree to alter their agreement to reflect changes in their relationship or financial sta​​​​ge.

🔑 Key Takeaway: Flexibility exists within the rigid structure of prenups, allowing for amendments or nullification under specific circumstances.
