This seminar will focus on recent developments in the law of capacity. To exercise legal capacity, individuals must have decision-making capacity. Some individuals have cognitive impairments that render them “incompetent” or “incapacitated,” and they are not permitted to exercise legal capacity contemporaneously. Decisions affecting their lives (and that have legal consequences) instead will be made by someone else (e.g., guardian, agent, family member, etc.) or via advance directive. Over the last decade, states have led the way in adopting supported decision-making laws that may increase the number of people with decisional impairments who can exercise legal capacity. This seminar will focus on international, federal, and state laws that facilitate the contemporaneous exercise of legal capacity for individuals with cognitive impairments and survey recent legal scholarship based on these laws. Students will produce an original paper on a topic of their choosing related to legal capacity.
