If a guardianship was established by a tribal court, only that court has the authority to modify it. Each individual tribe has its own rules and regulations which it applies to guardianship issues. Because there are special rules governing who can appear before a tribal court, it is a good idea to work with the tribe’s social services staff when researching a guardianship issue. They may be able to bring the matter to the tribe’s attention informally and work with the state to solve the problem. You should consult your guardianship contact when any tribal issues arise.
