Can a sibling ask POA to show records of accounts?

Yes, a sibling can request a power of attorney (POA) to show records of accounts, particularly if they have a legitimate interest in the affairs being managed. However, the POA is not legally obligated to disclose records unless specified in the POA document or required by law. If the sibling is concerned about the management of the accounts, they may need to consult a legal professional for guidance on their rights and options.
