This video discusses the issues that arise when someone is unable to sign documents in person and wants to use a power of attorney instead. The document that grants the authority to sign on behalf of someone else is important, and it needs to specify who can sign and what their powers are. Powers of Attorney can vary in scope, some may allow only simple actions, while others may grant broad authority over finances and properties. However, it is crucial to note that Powers of Attorney are for living individuals only and become null and void upon their death.
