Utah Code § 48-3a-304: Liability of members and managers.

(1) A debt, obligation, or other liability of a limited liability company is solely the debt, obligation, or other liability of the limited liability company. A member or manager is not personally liable, directly or indirectly, by way of contribution or otherwise, for a debt, obligation, or other liability of the limited liability company solely by reason of being or acting as a member or manager. This Subsection (1) applies regardless of the dissolution of the limited liability company.

(2) The failure of a limited liability company to observe formalities relating to the exercise of its powers or management of its activities and affairs is not a ground for imposing liability on a member or manager of the limited liability company for a debt, obligation, or other liability of the limited liability company.
