Is it valid for the owner to organize a lottery without property?

Invalid. The owners' committee is an autonomous organization organized by the owners themselves and elected according to law. At the owners' meeting, the owners' committee is responsible for the supervision and management of property service quality and charges, and has the right to negotiate and sign the contents of the property service contract, but has no right to change the property service enterprise. Therefore, if the owners' committee refuses the property by drawing lots, the purpose of replacing the property service enterprise cannot be effectively realized by the owners' committee's own decision, and can only be effectively realized by voting at the owners' meeting and obtaining the consent of more than half of the owners.
