How can i protect my interest in an llc?

If the LLc is basically your interest in a professional partnership type arrangment...say a consulting firm....try to show that their is no market for your interest..the value is really only comes from the involvement of those working in the business....hope none of your partners offers to buy out your interest...that type of thing. If there is value in your interest, and it isn't much more than an investment, your pretty much screwed...
