When your loved one signs for you to be Power of Attorney, be sure all names on the document match the legal names on your IDs (driver's license, etc.) We are selling mom's house this week, and I was told since I didn't sign my full name on the POA they might not go through with the sale. It has to match your ID/full legal name. Since mom now cannot sign a new POA we are stuck.
I had both my POA's done at a lawyers office over 2 years ago, and designated both my children as my POA's, and they were not with me, nor were they required to sign. Again, only the lawyer and 2 witnesses from his office signed them.
I'm guessing that perhaps you did the POA's that you print off from online and then take it to be notarized and 2 witnesses sign and you were one of the witnesses.
This might be a good lesson for folks to make sure that they spend the little bit of money that it costs to have a lawyer do any POA's needed. so as not to cause any issues.
I would imagine this also varies by state as everything seems to.
Good luck, for sure!
