No. Jhnblgr.
Those previous threads are simply wrong.
One might attempt in a lawsuit to "pierce the corporate veil", but generally speaking a person's private assets are shielded from legal judgement if the corporation is properly formed. There are things you can do, unknowingly, to compromise that, but generally this is a significant obstacle for your average lawsuit. NOT THAT I'M AN ATTORNEY. You might sell personal assets as the owner if you felt a personal obligation to pay some kind of judgement against a corporation you own, but generally, this is not a requirement.
Corporations, by the way, are generally obligated to defend their employees when they are doing their work for the employer lawfully. e.g. somebody embezzles from your company, you aren't obligated to provide them an attorney on that front.
Why exactly would O&E insurance exist if it doesn't do anything? Hmmm? Why would a large corporation like, say, Siemens, have it? Why would General Re exist?
XR250 - sole proprietor or were you incorporated to some extent?
There are also about forty different corporate structures, full on incorporation, professional association, professional service corporation, etc, etc, etc, which are open to professionals that are not open, say, to an automobile manufacturer.
Further, to clarify yet another misconception. General liability is most commonly held for stores with physical locations as the public can enter them and get injured. It is "slip and fall" insurance, to some degree. If you never have any clients inside your house, there's no physical store. This is a bit of an argument I got into with somebody back when, where they insisted (as a sole proprietor independent contractor) I maintain GL, and worker's comp (I have no employees and am NOT incorporated), name them as a third party insured, and I declined. They eventually "left" the company and I continue to do work with them, unabated.
To quote Jay-Z......
Listing people randomly on your insurance as third-party has effects. Not on the cost of the insurance.
