Which of the following is a person under disability?

• A. Adult
• B. Infant
• C. Incompetent
• D. Unknown

Answer: (B)

In Surrogate’s Court practice, a person under disability is someone who cannot manage their own affairs due to age or incapacity and therefore needs a guardian or other protective proceeding. The clearest example among the options is an infant, meaning a minor under 18. Minors are presumed incapable of handling legal and financial matters, so they are considered persons under disability and require a guardian to protect their interests.

An adult isn’t automatically under disability unless a court has specifically declared them incompetent; that’s a different, specific status. A person whose status is unknown isn’t a person under disability by itself. So the infant is the correct choice because a minor clearly fits the definition of a person under disability in this context.
