Can POA for these things be done via Legalzoom or similar ‘do it yourself’ forms for various states or must you hire a lawyer?
Does the lawyer have to be from the state the elderly person resides in or can a lawyer in another state draw it up and have it sent to them to sign?
Wills and POA's are not that complicated, so sites like Legalzoom should be useful. Wills should be registered with your State's probate courts, to avoid complications after that person passes.
Re: POA's, my parents were in-state, so we could be there to assist. POA's have broad authority. In NY State, for example, POA's need to be registered, IF the power to sell real estate is granted within a POA. Otherwise, they need only be notarized, it seems. Google POA and your state. You'll find all kinds of websites offering information.
