1, commercial housing subscription book has the force of law. As an equal civil subject, the contracts and agreements signed between the developer and you under the condition of free will are valid as long as they do not violate the mandatory laws of the state. Commercial housing subscription book needs to affix the special seal for the contract, but the special seal for expropriation can also indicate the identity of the developer, because both the seal for expropriation and the seal for the contract are legally registered in the industrial and commercial department, and the act of affixing the seal is the developer's will, which does not affect the validity of the subscription. The absence of a legal person's signature does not affect the effectiveness of the company's expression of will and subscription.

You can pay the full amount today, as long as you get the purchase invoice after paying the fee. If you can only issue a receipt now, you can indicate the time when you received the purchase invoice on the receipt.

3. If the developer runs away after paying the house price and signing the subscription book, he can bring a lawsuit to demand the return of the house price and interest. If it is an existing house, it is unlikely that the developer will run away. If it is a pre-sale house, the developer should be required to provide a pre-sale permit. The developer who has obtained the pre-sale permit said that he has paid all the land use right transfer fees, obtained the land use right certificate and held the construction project planning permit. The project construction investment accounts for more than 25% of the total investment, and the construction progress and completion delivery date have been determined. Developers who can show pre-sale permits are more reliable.

4. Generally, a paper contract is signed first, and then the developer uniformly handles the initial registration and online signing.
