When parents or grandparents are able to pass down residential property or a family business to their children and grandchildren, it should be a piece of the American Dream come true. And, with foresight, good planning and a little bit of luck, it can be. Too often, however, these "gifts" can devolve into situations that tear extended families apart. It often doesn't take long before family members start to treat each other unfairly and eventually become openly hostile towards each other.
