My father's father and his brother and three sisters owned land in Italy. They are all deceased. All of them but one of the sisters bequeathed the land to my father. The one sister has five heirs who, according to records in Italy, live in Canada, but we don't know where they live or if they're even alive. Since the land we're trying to sell is 4/5 in my father's name and 1/5 in the name of these Canadian heirs, we don't know how to proceed. Can we sell the land and keep 1/5 of the money in an escrow account? Or can we simply put out an ad in various Canadian papers asking for them to come forward within a specified amount of time? Can anyone help with this?
