You incorporated your roong business. You are the sole shareholder, director, and also the President. Although it is a small business with you as the sole employee. you have managed to be profitable (even in 2020 with Ccvid). You run the business out of your home and do not maintain a lot of business assets. You are now being sued by a former client who claims {after paying you in full) you did a substandard job and within 12 months the entire roof had to be replaced due to it leaking. You have a simple standard form business contract in the name of your business and you used that here. However, he is suing you personally. Explain how the plaintiff might attempt to establish personal liability and whether you need to be concerned about the basic claim as well as the claim for personal liability and why based on the legal concepts learned in this course
