Only subscription book, developers can unilaterally sign online without notifying property buyers?
Only the subscription book, developers in the absence of notice to property buyers, can not unilaterally sign online. Because even online signing should be the expression of the true meaning of both parties, it is impossible to express the true meaning or even know it without one party present, so online signing is illegal. If negotiation fails, the case can be brought to the court of contract dispute for judgment. It is recommended to consult a lawyer and protect rights according to law.
