Binding financial agreements (sometimes called ‘prenups’) can help manage risk and create certainty in some situations. They can be made before, during, or after a relationship, depending on the context.

What a BFA is (in practical terms)

A BFA is a formal agreement that sets out how property and (in some cases) spousal maintenance will be dealt with if a relationship breaks down. The goal is usually to create clarity and reduce future disputes.

Common situations where BFAs come up

  • Significant pre-existing assets
  • Second relationships / blended families
  • Family business interests
  • Inheritance expectations
  • Unequal contributions where both parties want clarity

When BFAs can be helpful

  • Both parties want clear expectations and are negotiating early
  • There is a genuine desire to reduce risk and uncertainty
  • The agreement is prepared carefully with appropriate advice and disclosure

When BFAs may not be suitable

  • One party feels pressured or rushed
  • There is limited disclosure or uncertainty about assets
  • The agreement is treated as a template rather than tailored to the relationship
  • Circumstances are changing rapidly (health, children, finances)

How this connects to property settlement

Many people compare BFAs with consent orders when formalising a property settlement. The right approach depends on timing, complexity, and your priorities.
