If the developer does not give the online sign, he can complain to the local housing authority or the inspection Committee, and the developer needs to complete the online sign within the specified time.

Under normal circumstances, it will be handled within 30 days after signing the purchase contract. If it is not handled within the specified time, it is illegal.

In addition, it is necessary to negotiate with the developer before complaining. If it can be settled through consultation, there is no need to sue. Before the signing of the housing network, the area on the contract is the predicted area. Only after the online signing, the Housing Authority will conduct acceptance and determine the final area. Moreover, before the online signing, the Housing Authority will not take care of it.
