My sister signed a Power of Attorney over to me so I can sell a house we own together. She is out of the country, The PoA was notarized and witnessed by two people, but the witnesses did not sign - they only printed their names (as indicated on the PoA). This was not a problem for signing the sales contract, but the buyer now wants witness signatures at closing. The buyer is not an attorney.
Are witnesses even needed in this situation (a notary signed the PoA)? If they are, must they SIGN the document or is their printed name enough to continue with closing.
