New Jersey Legal Ages Laws

Created by FindLaw's team of legal writers and editors | Last updated March 09, 2018

Most legal processes only apply to adults, those who are 18 years and older in most states -- although there are exceptions in every state for certain situations. Because they are still in the process of developing an understanding of behavioral and social norms, most people agree that young children should not be held legally accountable for their actions. In legal terms, children are said to lack legal capacity, and therefore are not treated and/or punished in the same way as adults. This makes sense, since the law does not, in general, hold people accountable who lack the mental capacity or maturity to understand the consequences of their actions. But at what point does a child legally become an adult -- i.e. when does an individual attain legal capacity?

Since maturity varies from person to person, when it comes to assigning an age for attaining legal capacity, states must draw a line somewhere -- even if it is somewhat arbitrary. While some states set a definite age at which a minor may be emancipated, New Jersey law does not specify an exact age (instead, it's decided on a case-by-case basis). The law also address things like the ability to enter into a contract, the ability to sue, and the age at which a minor may consent to medical treatment.
