I am looking for help on a real estate issue in Gaspe Quebec…

I am looking for help on a real estate issue in Gaspe Quebec Canada. My dad passed away about 8-1/2 years ago. He did not have a will. He was married at the time of his death, but not to my mother. They had been divorced for probably over 20yrs prior to his death. The woman he was married to had three kids at the time of his death. None of them were his and he never adopted them. I have 5 brothers and one sister. Our concern is a piece of property that my dad was the owner of at the time of his death. This piece of property is in Gaspe Quebec Canada. The property has been in my dads (our) family for several generations. The property is undeveloped and mainly consists of trees. After my dads death my oldest brother was added to a local bank account that my dad used to pay the property taxes. Since his death my oldest brother has been paying the taxes out of that same account for the last 8yrs. His wife at the time has no interest in the property other than maybe getting some money for it. What we (all my brothers and sister) would like to is get this property leaglly into one or all of our names. If it makes any difference all my brothers and sister except one brother are still Canadian citizens. My dads wife at the time of his death is an American citizen and so are all 3 of her children.
