Sometimes when changing from city, country or house we take the time to trash and sort all this papers but if we are not «forced» probably we never do. When we do we find things that we didn’t remember of and after putting our memory at work we remember what that was about.
Imaging what happens if is another person who is trying to dig into those papers. A complete mess.
So we better start selecting, scrapping and locate those important papers (deeds, mortgages, heritages, loans, bank accounts, property and so on and so forth) into a place where just the people you decide have access and have complete information of what is all about.
Better safe than sorry.
