Regarding the above subject which provides guidance on how to evidence applicants' intent to apply for joint credit, can someone point me to what is the recommended disclosure for a home equity application?

If you look at Regulation B, Appendix B, it shows examples of application forms. For home equity you would need the credit application for secured credit.

Depending on your forms company - they may be updating applications to accomodate the requirements of Reg B joint applicants. We use Bankers System and the new application forms we just ordered have a specific area on the app that requires initials of the joint applicants stating that they are applying jointly for the credit.
