b) If Arleen applies for guardianship, the guardianship designation must take effect before Caelan becomes mentally incapable.

c) If Caelan establishes a living will, Arlene will automatically be delegated the authority over financial decisions for Caelan.

d) If Arleen is appointed the attorney under an enduring power of attorney, the designation would end when Caelan becomes mentally incapable.
