I guess, one can assume that all countries with working institutions (and some without) have at least a simple personal liability corporation, which is easy and cheap to establish, and a basic limited liability corporation, which is a little bit more involved and expensive to establish. I guess, because I haven't done any research, but I've come across such corporate forms in Germany, Italy, France, UK, Luxembourg, Hungary, Serbia, Congo, UAE, Estonia, Netherlands, Denmark, Norway, USA, Canada, the Philippines and probably a few more.
