Suing an LLC
When you are suing an LLC, you are not going to be pressing charges against the owners.  It will only be against the company itself, as the way LLCs are constructed allows for the owners of the LLC to keep their business and personal assets separate. 

There are, however, certain conditions which allow you to hold a LLC owner personally responsible.  Depending on where they are incorporated will determine how hard it is for you to be suing an LLC.  If the LLC is incorporated in states that protect against piercing the corporate veil (i.e. Directly holding the members accountable) then you might have to settle with only suing the company itself.

There are certain cases in which suing an llc will allow you to hold its owner or other members personally accountable, however.  In cases of fraud, negligence, or illegal activities, you will have a much easier time in pressing charges against individuals as opposed to the entire company.

If you are the owner of a LLC and are worried about people who decide they are suing an LLC, make sure you take the necessary precautions.  Incorporate in a state that allows you near total privacy, as that will hold off many people that will jump on any little chance to sue you (this is referred to as the deep pocket syndrome).  You will also want to ensure that you cannot be found guilty of fraud of any kind – that would make you personally liable for any charges brought against your LLC. 

Suing an llc is probably not the best course of action, especially if you have a frivolous case.  LLCs may or may not be large businesses, and your legal costs may greatly exceed that which you would receive if you do choose to sue.  Settlement out of court would most likely be your best option, and one that most businesses would be happy to take. With more and more lawsuits getting thrown around every day, you will want to do your best to protect yourself, as well as only suing if you have just cause.  After all, you don't want to get sued yourself.
