The manager of an LLC has apparent authority to deed property owned by the LLC. If an LLC has been dissolved, the manager still has authority to act for the LLC to help it wind down its affairs (which would include disposing of property which it owned). By deeding the property to himself, the manager may have breached his duty to the members of the LLC, but this would not affect the validity of the deed. To completely answer your question, I would have to review all of the documents involved. If you would like to meet with me for such a review, you can call my office at 813-434-4800 to make an appointment.
