@Mike H. not sure about if his friend had an umbrella coverage. But we covered this topic I believe on another page. Insurance and an Umbrella coverage is good and a must have, but really read your ENTIRE policy and the fine print and have your lawyer read it for you and negotiate its terms just like @Jay Hinrichs said. Most don't realize you can negotiate the terms. But don't misconstrue what Jay said, he also has something like 11 LLC and runs everything through his business, and also has insurance, negotiates those terms, and lives in an Asset Protection friendly state for the majority of the year as his residency. So he is not just relying on insurance, but practices proper methods of multiple layers of protection, and uses his team (Layers, CPA, etc) to make sure he is protected.
Umbrella policies say they are their to protect you from large lawsuits and damage awards, but if you read the fine print, their are lots of outs for them to not pay. They are a business with an entire area of law called Insurance Law for them and insurance lawyers. They would not be in business if they have to pay every claim, or the full amount. They will not pay punitive damages, they will not pay for reckless or outrageous conduct, they will not pay for intentional acts and anything they deam as fraud, and that clause is the death clause since they can use any conversation you had as intent and fraud. They will go back to initial conversations you had when starting your policy to prove intent and fraud. They will not cover activities of an insured as a director or officer, or business activity since business umbrella policies are for business and different then personal ones. And the list keeps going on what they won't cover, let alone what their legal team will argue and decide. Remember, its a business.
On piercing the veil, the point of a LLC or Business Structure is to keep separation from you personally, But that requires you to run it properly. The point is to create more damns to cross to get to you and more time, energy and expense of the person suing you. To try to pierce the veil it takes lots of time and money. Its just not a simple as saying, hey lets pierce the veil. Having a set up AP structure will generally facilitate faster settlements and at a cheeper amount, if not just prevent the suit from being filed since the lawyer deciding to file it will make a business decision on if his time, energy and resources will be awarded or not with the judgment? Yes, the corporate veil has been slightly deteriorated, but it still is regularly upheld and recognized in a structures integrated overall strategy where a LLC is used inside an overall plan holding a single asset. The courts typically give it the benefit of the doubt, and will force the plaintiff to show the company is a shame. Which it is not, since you are using your team to properly keep you up to regulations (CPA, Lawyer).
