In clinical geriatric psychiatry, it is an accepted standard of care to obtain corroborative information when conducting clinical evaluations.However, medical-legal tasks of capacity evaluation, such as for the evaluation of capacity to instruct counsel, testamentary capacity and possibly even capacity to appoint powers of attorney, may require strict confidentiality which prevents obtaining corroborative information from informants. As a result, obtaining corroborative information for capacity evaluation in this context is more complex than in clinical care.
