She is entitled to know what is being done with the property. If mom is incompetent confirm there is no court proceeding for guardianship pending. if there is the agent's power to act is temporarily suspended pending outcome of guardianship proceeding. 3) ask for an affidavit of the agent (Fla has a form affidavit that the DPOA is effective and agent acting within scope of authority.
