Quote from @Drew Sygit:
If a legal issue occurs with your property resulting in a lawsuit, there's a decent chance the plaintiff's attorney will be successful in "piercing the corporate veil" of your LLC and being able to sue you directly.
To pierce the company veil of an LLC is not that easy. Of course if you are sloppy and commingle fund, or not record annual meetings, or sign in your personal name instead of the LLC name, that will make the job of the plaintiff easier. But with basic company management and bookkeeping, the hurdle to pierce the company veil is very high.
I would suggest the latest book from Garrett Sutton,
Veil Not Fail: Protecting Your Personal Assets from Business Attacks, that goes in detail into the errors not to make to avoid piercing the veil.
Anonymity is also recommended to avoid ambulance chaser attorney finding your assets.
I have seen in this forum a lot people complaining that it was not worth it as in a lawsuit you have to disclose your assets. No, you will only have to disclose your asset during a late phase of the lawsuit, mainly if you have lost. By hiding your asset, you are already avoiding many lawsuits to start.
Also by having LLCs, the plaintiff's attorney will only have a reasonable expectation to get only the company asset. If they are mortgaged, there is not a lot of equity left to reach. And as it is very unlikely to pierce the veil and will take a lot of attorney's resources, if there is no known other assets to go through it will be difficult to justify the cost. You will get in a much better position to settle for the insurance amount than going to a full lawsuit.
Last, even if the corporate veil is pierced into one of your LLC, if everything else you own is in other LLC, the plaintiff will then need to reverse pierce the veil on these other LLCs too as the charging order will block any access.
