Incapacity, or inability, refers to a state where an individual is unable to perform certain tasks or make decisions due to physical or mental limitations. This can arise from various conditions, such as illness, injury, or cognitive disorders, affecting a person's capacity to function normally in daily life. In legal contexts, incapacity often pertains to a person's inability to manage their affairs or make informed choices. This can lead to the appointment of a guardian or power of attorney to assist or make decisions on their behalf, ensuring that their needs and rights are protected.
