Hi:
Disclosure: I am not an attorney.
I just attended a 2 day seminar on this subject and I agree in different ways with both @Cory Borenand @James Miller. I just had a conversation today with a friend who has high net worth. Her CPA formed her single member LLC with the state. Apparently, she has no operating agreement in place. My understanding is that one of the key reasons for intiating an LLC (as opposed to a sole proprietorship) is to provide asset protection to the member so that a judgement cannot be attached personally. You have to dot your I's and cross your T's on the paperwork to get proper asset protection. Formimg it, paying your yearly fee and ignoring the requirements will put you at potential risk.
In the case of my friend, if she is sued, with no operating agreement in place there is the possibliity that a judge could rule that the LLC was invalid and that "the veil could be pierced", thus she could end up with a judgment against her personally.
If you are a newbie and have no assets, I agree there may be little risk as there are no assets to attach. But if you go down this road and become more successful without becoming educated, there could be negative ramifications in the future. Best to have a complete understanding which hopefully you will get from all of us posters!
Best of luck!
