Real Estate / Can I sell my home in Poland remotely? [2]

I am British, residing and working in the U.S.A. I am recently divorced from my Polish wife that lives in Poland in our family home. I would like to sign over power of attorney to my ex wife so she can list the family home for sale. Can this be done remotely? I intend on giving her all proceeds from the sale of the home so she can purchase a more reasonable flat. Any suggestions or advice is appreciated.
