Commitment letter of residential owners to build sun rooms

Legal analysis: Letter of Commitment, if the obligation is unilaterally set, the obligor must sign it (legal person or organization should seal it). The counterpart of acceptance is a simple obligee, and the absence of signature by the obligee does not affect the validity of acceptance. For example, for the transfer of unilateral rights, the transferee of rights need not sign, but should inform the obligor of the transfer of rights.

Legal basis: Article 937 of the Civil Law of People's Republic of China (PRC) is a property service contract in which the property service provider provides the owner with property services such as the maintenance of buildings and ancillary facilities, the management and maintenance of environmental sanitation and related order, and the owner pays the property fee.

Property service providers include property service enterprises and other managers.
