Can you garnish funds from an llc account?

Short answer, no. Many states do allow a charging order, but the entire premise of the llc is to protect business assets and allow the business to continue to operate. A charging order simply garnishes any distributions from the llc, but the company's bank account belongs to the company, which is its own entity.

That said, there are circumstances where you can "pierce the veil" of corporate secrecy if you have a strong enough case to convince a judge that there is either fraud or that humanity will be irreversibly wronged (the Oklahoma principle) if you can't open up the llc, but it's a tough sell in most states including mine because the entire llc concept is to allow people to separate their business and personal lives.
