my father Doctor wrote a letter that he is a vulnerable adult and his PoA needs to be invoked to make financhal and medical decisions in November. i was unaware of it cause I was on bed rest and recovery from knee and hip replacement and it’s now June and I haven’t done it yet. is it a requirement of a POA to invoke it,
You will need to have his physician put this in letter form on his clinic's official letterhead and then print it out. You will need to show it to banks and other financial institutions if you wish to now manage his affairs as his active PoA.
I just did this for my Mom. I had been operating, with her permission, as her Durable PoA. Now she has advancing dementia and memory issues and has poor judgment and executive skills so I am managing almost everything for her daily.
I needed this letter plus signed affadavits to manage her investments. Other medical clinics may require it. His bank will have a rigorous protocol as well. Having the letter means you now won't need to bring your Father with you to accomplish certain tasks.
Be sure to review the entire PoA document so that you know exactly what authorities you have on his behalf.
