N.J. Stat. Ann. § 54:8A-11

"Dependent" means any individual related to taxpayer, over half of whose support (exclusive of any amount received by a child or stepchild as a scholarship for study at an educational institution) for the eligibility year was received from the taxpayer, in fact or constructively. No person may be claimed as a dependent by any taxpayer if such person has filed a joint return with his or her spouse.
