A juvenile is considered neglected under custody law when they do not receive:

In the context of custody law, neglect refers to a situation where a juvenile is not receiving the essential care and support that they need to grow up safely and healthily. The correct answer identifies "proper care, supervision, or discipline" as the basis for considering a juvenile neglected.

Proper care encompasses various aspects, including physical needs like shelter and nutrition, as well as consistent supervision to ensure the child's safety. This also involves appropriate discipline that contributes to the child's development, teaching them boundaries, and helping to foster self-control. When a juvenile lacks these critical elements, their wellbeing is at risk, which is why this option reflects the core of what constitutes neglect under custody law.

While financial support, emotional support, and education are all important for a child's development and stability, the specific focus of neglect law regards the absence of adequate care and supervision. Thus, even if a child receives financial or emotional support, if they lack proper care, supervision, or discipline, it can qualify them as neglected according to the pertinent legal definitions.
