DanushaNowakows i 19 May 2017 #31My biological grandfather owned 3 plots of land in Poland. He left that property to my biological father. My biological father gave Power of Attorney to another relative in Poland as my father liived in the U.S. My biological father passed away 2yrs ago. I understand that this makes the Power of Attorney for our Polish resident relative no longer valid, I think.In my biological father's will, I was disinherited, I strongly believe at the pressure of his 4th wife with whom he had no children. I am the oldest living heir. My mother was recently in Poland and we heard about these 3 plots of land for the first time. They were not mentioned in my father's will, written in the U.S.My question now, is that I don't believe his widow, nor any of the other children are aware this property even exists. I would like to proceed with selling the land and accepting my share of the proceeds.I'm not sure what impact the U.S. will has over Polish laws. I don't even know where to begin. I would like to move quickly. Please advise on where to begin and which documents I will need. There was something related to my father's will that I was asked to sign. I never did. I appreciate any advice you may have!
