Yes. A BFA can deal with only some of the assets and financial resources of a marriage or de facto relationship.

Parties often wish to quarantine a particular asset or resource (such as premarital property, business interests or family heirlooms) or deal with it in a particular way.  This is particularly common for parties entering into a second relationship who want to ensure that their assets are preserved for the benefit of their children, rather than their new partner or the new partner’s children.
