Let's say you are a builder working on multiple projects. You have registered each one as a spv. if due to some unavoidable reason there is an accident and few people lose their life/property. Or if One of the business goes bankrupt, then Your personal property & other spv wouldn't be liable to cover the liability of that particular spv. This is limited liability. But this is enforceable only if you operate that spv as an spv( different special entity). If you accept /do payment using your personal account( or other spv's account), use business property for personal benefit (Even if you are sole owner) etc then opposing counsel can argue you took no step to separate your business from yourself. Then you become liable to pay your business liability.
