Who do I indicate as my legal parent and guardian when my mother is remarried. Both my mom and step-dad jointly own a business, therefore I placed her and his joint income as out family income, so do I place my step-dad as my legal parent? On my Fafsa I had to use both my stepdad and my mothers income, because I live with them 50% of the time. Does this still apply to my UC Application? Since, my biological dad is still fully involved with my life, but he and my mom have no official separation documents (they were never married), who should I put?
