My father, living on an island in the Caribbean, will be sole beneficiary of his sister's(who lives in Germany) estate. Due to his inability to travel, he has prepared a power of attorney with jurisdiction for our country and Germany so that I can legally represent him when I go to Germany to deal with sale of apartment, burial and any thing else that needs to be sorted out.
Is there going to be a problem with my father's power of attorney which has been prepared in our country? If so, what would you advice?
