The form is available on NB site, but it is put in another category documents list. However, If you intend to include your common-low parther in your application, you must fill that form. What I did was to fill that form and went together with my partner to Notary Public where we just sign it. And yes, you have to provide all documents you declare in that form - leases, common depostits, ect..
thanx Svetlanka, seems that married couples don't need to attach that form.
