The age of consent in New Jersey depends on the social relationship between sexual partners. The general age of consent is 16. Teenagers as young as 13 may consent to a sexual relationship, as long as their partner is at least 13 and no more than four years older than them. When a position of power exists, such as between teachers and students, employers, coaches, etc. the age of consent is 18. Absolutely no one younger than 13 can legally consent to sexual activity.
