A concise, practitioner‑focused introduction to Supported Decision‑Making (SDM) that summarizes what SDM is, how it differs from conservatorship, and how professionals should implement SDM in routine practice. The brief explains statutory recognition of SDM following AB 1663, defines SDM agreements and signature/witness formalities, and highlights professionals’ obligations to permit supporters to attend and participate in meetings and communications (including IEPs, care planning, discharge planning, and financial meetings). It clarifies when a third party may refuse supporters (reasonable belief of fraud, coercion, or abuse) and notes that recognizing SDM agreements may constitute a required reasonable accommodation under state and federal law.
