Community owners spontaneously advocate the signature of community owners. Does the evaluation of property management need the authorization of the neighborhood Committee? Does the obtained data have legal effect? No authorization is needed, because both the Property Law and the Property Management Regulations stipulate that owners can exercise autonomy in the community. In China, we belong to the management and service work under the leadership of the government, so we can report to the community neighborhood Committee when carrying out the above work.

The data obtained must have legal effect, but the legal effect refers to the convening of the owners' meeting, and the major public affairs in the community must be approved by more than two-thirds of the owners and more than two-thirds of the construction area in accordance with the provisions of the Property Law, which is legal, otherwise it will be invalid.
