The forms specified by this division may be used, at the option of the party, in any proceeding involving a financial obligation growing out of the relationship of parent and child or husband and wife or domestic partners, to the extent they are appropriate to that proceeding.

Notwithstanding any other provision of these rules, all Uniform Interstate Family Support Act forms approved by either the National Conference of Commissioners on Uniform State Laws or the U.S. Department of Health and Human Services are adopted for use in family law and other support actions in California.
