Therefore, this paper examines the role required by the lawyers focusing on groups related to adult guardianship or lawyers among professionals. In summary, first, there are issues which require to appoint lawyer as adult guardians (including guardianship, assistance, help). Second, if lawyer is appointed as adult guardian in the future, he/she must comply with not only the right of representation of simple property management and legal act on property management but also obligation to consider his/her own opinions. And to practice this, he/she must closely work with welfare officials who support adult ward in the community to act as a member of network that supports adult ward.
